    CAE, INCORPORATED,
    Plaintiff-Appellee,
    v.
    CLEAN AIR ENGINEERING, INCORPORATED,
    Defendant-Appellant.
    Appeal from the United States District Court
    for the Northern District of Illinois, Eastern Division.
    No. 97 C 3264--Warren K. Urbom, Senior Judge./1
    ARGUED MAY 9, 2001--DECIDED October 2, 2001
    Before RIPPLE, MANION and KANNE, Circuit
    Judges.
    RIPPLE, Circuit Judge. Appellee CAE,
    Inc. is a large, Canadian conglomerate
    whose operating subsidiary companies
    manufacture, among other things, aircraft
    simulators, air traffic control systems,
    medical equipment, and data acquisition
    systems for various industries. Appellant
    Clean Air Engineering, Inc. ("Clean Air")
    is an Illinois corporation whose core
    business is technical environmental
    consulting and air emissions testing.
    CAE, Inc. claims that Clean Air’s use of
    the initials "CAE" infringes CAE, Inc.’s
    federally registered "CAE" trademark.
    After a hearing on CAE, Inc.’s
    opposition to Clean Air’s application to
    register the CAE mark, the Trademark
    Trial and Appeal Board ("TTAB") found
    that, despite CAE, Inc.’s use of the CAE
    mark since the early 1950s and its
    federal trademark registration since
    1972, Clean Air’s use of a "virtually
    identical" mark was not likely to cause
    confusion among consumers. R.34, Ex.4 at
    5. The district court disagreed; it found
    that consumers were likely to be
    confused. The court entered judgment in
    favor of CAE, Inc. and enjoined Clean Air
    from future use of the initials absent a
    disclaimer of any association with CAE,
    Inc. Clean Air appeals. For the reasons
    set forth in the following opinion, we
    affirm the judgment of the district
    court.
    I
    BACKGROUND
    A.    CAE, Inc.
    CAE, Inc. was formed in 1947 as Canadian
    Aviation Electronics, Ltd. The company
    began using the CAE mark in the early
    1950s and officially changed its name to
    CAE, Inc. in 1993. Now a holding and
    management company, CAE, Inc. owns and
    controls approximately twenty subsidiary
    companies, eight of which are
    headquartered in the United States, and
    it employs nearly 6,000 people. In the
    1980s, CAE, Inc.’s export sales to the
    United States averaged over $100 million
    (Canadian), which comprised approximately
    twenty-five percent of CAE, Inc.’s gross
    revenue. In the 1990s, this figure rose
    to $430 million (Canadian), which was
    forty percent of CAE, Inc.’s gross
    revenue.
    Since the 1950s, CAE, Inc., through its
    subsidiaries, has designed, produced and
    sold a variety of testing and measuring
    equipment in the United States under the
    CAE name and mark. During the 1960s, CAE,
    Inc. began to design and to manufacture
    testing and measuring equipment,
    including hydrological sampling
    equipment, portable grain temperature
    probes and moisture meters. With the
    purchase of the Link Simulation and
    Training Systems Division of the Singer
    Company in 1988, CAE, Inc. became the
    world leader in simulation training. CAE,
    Inc. sold the assets of its simulation
    training operations in 1995.
    1. CAE, Inc.’s Registered Trademarks
    CAE, Inc. has been using the letters
    "CAE" as a trade name and service mark
    since the early 1950s and owns six
    registered trademarks containing "CAE."
    The first two trademarks, registered in
    1972, are for goods described as
    "[e]lectronic apparatus and equipment--
    namely, simulators, visual display
    systems and motion systems for use with
    simulators; supervisory control and data
    logging equipment and systems; and
    magnetometers and magnetic anomaly
    detection equipment." R.34, Ex.4 at 4.
    One of these trademarks, registration no.
    939,840, depicts the following letters
    without stylization or design: CAE.
    Registration no. 939,841 depicts the
    letters CAE within a design. In 1980,
    CAE, Inc. registered a third trademark,
    no. 1,135,602, which depicts the letters
    CAE within a design, for use in
    connection with "[n]uclear power station
    training simulators and air traffic
    control radar data processing and display
    equipment--namely input receivers,
    processors, interface units, displays,
    control stations, line printers, and
    flight plan entry consoles." 
    Id. at 4-
    5./2 CAE, Inc. holds three additional
    trademarks: no. 877,750, registered in
    1969 for "DATAPATH CAE," R.38-1, Race
    Dec., Ex.7; serial no. 74-407,272,
    registered in 1993 for "CAE SELECT," 
    id. Ex.6; and
    no. 2,106,086, registered in
    1997, which depicts CAE inside a new
    design, see 
    id. Ex.5. CAE,
    Inc. features
    the CAE mark in the names of all twenty
    of its subsidiaries and divisions,
    including those headquartered in the
    United States: CAE Electronics, Inc.; CAE
    Screenplates, Inc.; CAE McGehee, Inc.;
    CAE Ransohoff, Inc.; CAE Blackstance,
    Inc.; CAE Ney, Inc.; CAE Alpheus, Inc.;
    and CAE Vanguard, Inc./3 Those entities
    owned by CAE, Inc., but without CAE in
    their names, feature on their stationery
    and product literature a reference to
    their association with CAE, Inc. CAE,
    Inc. never has sold or assigned any
    rights in the CAE mark as a trademark,
    service mark, trade name or otherwise.
    2. CAE Electronics, Ltd.
    CAE Electronics, Ltd. ("CAE
    Electronics"), the largest of CAE, Inc.’s
    subsidiaries, is a world leader in the
    design of advanced technology products
    and systems. It is comprised of four
    divisions: commercial flight simulation,
    military simulation systems, marine
    control systems, and energy control
    systems. CAE Electronics’ core products
    include supervisory control and data
    acquisition ("SCADA") systems. SCADA
    systems are mechanical and
    electricalsystems used to automate
    processes and to provide operators with
    continuous real-time monitoring
    information. Using sensors, monitoring
    equipment and control devices, these
    systems optimize operator and system
    efficiency, allow users to evaluate
    processes and maximize use of resources
    to reduce operating costs and to increase
    profits of SCADA customers. CAE
    Electronics customizes each SCADAsystem
    to meet the customer’s needs and the
    requirements of the particular industry
    and process in which it is used. CAE
    Electronics prints the CAE mark on each
    SCADA system component and its packaging.
    Since the 1960s, CAE Electronics has
    developed, manufactured, and sold its
    SCADA products and systems for
    applications in the telecommunications,
    oil and gas, and hydro-electric power
    industries. In 1973, CAE Electronics
    adapted its SCADA technology for the New
    Brunswick Electric Power Commission to
    monitor and control an oil-fired thermal
    generating plant. The SCADA system
    designed by CAE Electronics for this
    utility gathered, processed, and
    displayed data from three generating
    units, and it monitored more than 2,000
    parameters of generator performance,
    including emissions. Also in the 1970s,
    CAE Electronics adapted its SCADA
    technology to monitor and control nuclear
    power generating systems, to
    monitorenvironmental variables in arctic
    environments, and to assist air traffic
    control systems. In the 1980s, CAE
    Electronics introduced marine control
    systems for naval vessels, using SCADA
    technology to monitor air quality; to
    detect dangerous conditions, such as
    smoke, ionization, and explosive gases;
    and to optimize vessel fuel usage. CAE,
    Inc. maintains that CAE Electronics’
    SCADA systems are capable of monitoring
    and controlling environmental variables
    such as smokestack emissions and other
    gaseous or aqueous emissions. At this
    time, however, CAE Electronics does not
    manufacture or market its SCADA systems
    for use in air emissions testing.
    3.   CAE Fibreglass Products, Ltd.
    CAE Fibreglass Products, Ltd. ("CAE
    Fibreglass") designs, engineers, and
    manufactures various fiberglass products,
    including storage tanks, tank covers,
    washer hoods, air ducts and chimney
    stacks for use in the pulp and paper,
    chemical, oil and gas, and mining
    industries. Between the late 1960s and
    the 1980s, CAE Fibreglass designed and
    manufactured large-diameter fiberglass-
    reinforced plastic ("FRP") pipe for
    companies in the pulp and paper and elec
    tric power industries, including Kimberly
    Clark, Weyerhauser, International Paper,
    and Niagara Mohawk Power. In 1979, CAE
    Fibreglass designed FRP pipe for the
    Jacksonville Electrical Authority to
    address the environmental problems
    created by underwater discharge of heated
    water. In 1980, CAE Fibreglass entered
    into a joint venture with Construction
    International Limited ("CIL") to promote
    stack analysis, system engineering,
    installation, scrubber and dust design,
    fabrication, and quality control. The
    CIL/ CAE joint venture characterized its
    business as "TOTAL TECHNOLOGY IN
    POLLUTION CONTROL" and actively marketed
    its products and services through product
    literature, client meetings, conferences
    and trade shows. R.38-1, Lothamer Dec.,
    Ex.1 at 3. The CIL and CAE logos appeared
    on all joint venture materials such as
    stationery, envelopes, business cards and
    invoices. The joint venture resulted in
    several contracts in the United States,
    including contracts with Onyx Chemicals
    in Illinois, SeaWorld Marine Park in
    Florida, Leaf River Forest Products in
    Mississippi, and Texas Utilities
    Services. CAE, Inc. and CIL terminated
    the venture by mutual agreement in 1983.
    4.   CAE Screenplates, Inc.
    CAE Screenplates, Inc. ("CAE
    Screenplates"), a wholly owned subsidiary
    of CAE, Inc., designs, manufactures, and
    sells screenplates, screen cylinders, and
    screen media used in the pulp and paper,
    chemical, food processing, petroleum and
    mining industries. The company’s
    precision-engineered screenplates are
    important components in machinery used in
    the production of pulp and paper. Its
    high-strength drilled screenplates are
    also critical components in "closed"
    washing and bleaching machinery, which
    reduces air and water emissions in the
    pulp-washing and pulp-bleaching process
    and thus assists pulp and paper
    manufacturers in complying with
    environmental regulations. The CAE mark
    appears on CAE Screenplates’ products and
    packaging, advertising materials, and
    brochures, and it is displayed at trade
    shows and exhibits where CAE Screenplates
    appears.
    One of the principal trade groups
    serving the pulp and paper industry is
    the Trade Association for Pulp and Paper
    Industries ("TAPPI"). TAPPI sponsors
    trade shows, which CAE Screenplates has
    attended since 1988 to exhibit its
    products and services. TAPPI also
    publishes the TAPPI Journal, to which
    most of CAE Screenplates’ customers
    subscribe and in which CAE Screenplates
    often is listed as a trade show
    exhibitor./4
    5. CAE, Inc.’s Advertising and Trade
    Shows
    CAE, Inc. and its subsidiaries promote
    their goods and services in a number of
    ways. For instance, the company
    advertises in trade publications such as
    the TAPPI Journal and Pulp & Paper,
    distributes informational brochures,
    sends direct mail, makes personal
    presentations, responds to requests for
    proposals ("RFPs"), attends trade shows
    and conferences such as the TAPPI shows,
    and posts information on its Internet
    website.
    6.   CAE, Inc.’s Competitors
    CAE Electronics’ chief competitors in
    the area of designing and manufacturing
    SCADA systems for energy control are ABB
    and Siemens. In addition to power plant
    control systems and power network
    management systems, which directly
    compete with CAE Electronics’ SCADA
    systems, ABB also sells air quality
    control services, including air quality
    monitoring and engineering, emissions,
    inventory, air quality permitting and
    coordination services, and environmental
    services in connection with power and co-
    generation. Siemens sells power
    transmission and distribution systems for
    energy control that compete with the
    SCADA systems designed by CAE
    Electronics. Siemens also sells systems
    for monitoring air quality and air
    purification. At present, however, CAE,
    Inc. does not perform environmental
    testing or consulting services.
    B.   Clean Air
    Clean Air is an Illinois corporation
    that employs 115 people. In the 1990s,
    Clean Air generated annual sales between
    $11.6 million and $18.7 million. Since
    the mid-1970s, Clean Air has used the CAE
    mark in various type styles, including
    plain capital letters without
    punctuation. On some materials, Clean Air
    prints "Clean Air Engineering" along with
    the letters "CAE," but it features only
    the initials "CAE" in the names of its
    several departments: CAE Analytical, CAE
    Diagnostic Services, CAE Process, CAE
    Source Testing, CAE Express, CAE VOC, and
    CAE Instrument Rentals.
    Clean Air’s core business is "source
    testing," which involves visiting the
    client’s place of business and running
    tests to determine whether the client’s
    processes comply with federal, state, and
    local laws concerning air pollution.
    Clean Air’s services also include
    technical consultation, research and
    engineering in the field of environmental
    processes. Clean Air’s clients usually
    are companies engaged in industrial
    processes such as combustion,
    manufacturing or spraying. Over the
    years, Clean Air has expanded the number
    of industries it serves to include the
    electric power generation, natural gas
    processing and petroleum refining, pulp
    and paper manufacturing, semiconductor,
    pharmaceutical, surface coating, chemical
    manufacturing and fuel combustion
    industries. It also manufactures and
    rents source-testing equipment, including
    data acquisition systems.
    In addition, Clean Air offers "process
    engineering" services, which include
    designing control equipment, improving
    the efficiency of existing control
    equipment, and providing flow modeling.
    Clean Air’s flow models have been used to
    investigate temperature mixing, pressure
    loss, and gas velocity uniformity for
    ovens, boilers, fabric filter systems,
    stacks, scrubbers and other components.
    Recently, in conjunction with Pegasus
    Technologies, Ltd. ("Pegasus"), Clean Air
    has begun selling components of
    SCADAsystems. In its promotional
    materials, Clean Air offers to provide
    knowledge and assistance in setting up
    and maintaining continuous emissions
    monitoring systems. Using Pegasus’
    NeuSIGHT product, which enhances the
    calculations of combustion control
    systems, data acquisition systems, and
    plant performance, Clean Air offers to
    help its clients refine their industrial
    processes to minimize emissions while
    maximizing "throughput." R.48, Ex.D at 3.
    Clean Air markets this technology for use
    with furnaces, boilers, incinerators,
    oxidizers, and pollution control
    equipment such as electrostatic
    precipitators and scrubbers.
    1.   Clean Air’s Departments
    Clean Air is comprised of several
    departments. CAE Analytical is a
    laboratory that conducts chemical and
    physical analysis of air samples to
    detect pollutants. CAE Combustion assists
    companies engaged in combustion processes
    in optimizing pollution control
    equipment, reducing emissions, and
    complying with environmental regulations.
    CAE Diagnostics analyzes airflow using
    modeling and laboratory resistivity
    testing. CAE Analytical, CAE Combustion,
    and CAE Diagnostics have been reorganized
    to form Clean Air’s CAE Source Testing
    Department. Clean Air’s remaining
    departments are: CAE Process, which
    designs and manufactures pollution
    control equipment; CAE Express, which
    manufactures pollution sampling and
    measuring equipment; CAE VOC, which
    provides services for volatile organic
    processes; and CAE Instrument Rentals,
    which provides equipment used in source
    testing.
    2.   Clean Air’s Advertising
    In the 1990s, Clean Air expended between
    $116,000 to $287,000 annually on
    advertising. Clean Air advertises in
    trade association publications and
    journals, including the TAPPI Journal and
    Pulp & Paper; distributes product
    information through direct mailings;
    responds to RFPs; makes personal visits;
    and posts information about its products,
    services and catalogs on the Internet.
    Representatives of Clean Air have
    attended conferences and trade shows, in
    cluding the Federation of Environmental
    Technologists; Electric Power Research
    Institute; The Joint Power Conferences;
    Polytec, Iron and Steel Show; and the
    Emerging Technology Conference. Clean Air
    also regularly advertises in Pollution
    Engineering, Environment Today, AWMA
    Journal, Environmental Protection,
    Pollution Equipment News, The Thomas
    Register, regional Yellow Pages, Food
    Processing, Environment Canada,
    HydroCarbon Processing and Environment
    Technology.
    C.   CAE, Inc. Discovers Clean Air
    In early 1991, CAE, Inc. first learned
    that Clean Air was using the letters CAE
    as a trade name and service mark. Counsel
    for CAE, Inc. wrote to Clean Air,
    alerting Clean Air of CAE, Inc.’s
    registered trademarks and its intent to
    defend them vigorously.
    D. Clean Air’s Application for
    Registration and the TTAB Proceedings
    On November 22, 1991, Clean Air filed an
    application to register its CAE mark
    pursuant to 15 U.S.C. sec. 1051(a)(1)(A),
    claiming a first-use date of December 15,
    1975. Clean Air did not request a
    stylized design or include "Clean Air
    Engineering" in the proposed mark, but
    applied to register its mark as follows:
    CAE. Clean Air sought registration of the
    mark for use in relation to "technical
    consultation, testing, research and
    engineering in the field of environmental
    processes." R.34, Ex.4 at 6.
    In January 1993, CAE, Inc. filed a
    notice of opposition to Clean Air’s
    application pursuant to 15 U.S.C. sec.
    1063(a). It asserted that: (1) Clean
    Air’s CAE mark is confusingly and
    deceptively similar to CAE, Inc.’s
    previously used and registered mark; (2)
    Clean Air’s CAE mark is confusingly and
    deceptively similar to CAE, Inc.’s
    previously used trade names; and (3)
    Clean Air’s CAE mark falsely suggests
    that Clean Air is associated with,
    sponsored by, or otherwise related to
    CAE, Inc.
    In November 1995, the TTAB held a
    hearing at which both parties appeared
    and presented evidence concerning the
    likelihood of confusion./5 See 15
    U.S.C. sec. 1067 (requiring the TTAB "to
    determine and decide the respective
    rights of registration" when an
    opposition to registration has been
    filed). In its written decision, the TTAB
    acknowledged that Clean Air’s proposed
    mark is "virtually identical" to the
    trade name and mark first used by CAE,
    Inc. in the 1950s and registered in 1972.
    R.34, Ex.4 at 5. Despite this visual
    similarity, however, the TTAB concluded
    that there was no likelihood of confusion
    because: (1) the parties’ goods and
    services were dissimilar; (2) the
    parties’ customers were sophisticated
    purchasers of expensive and
    individualized goods and services; and
    (3) there was no evidence of actual
    confusion. Accordingly, the TTAB
    dismissed CAE, Inc.’s opposition to Clean
    Air’s registration of the CAE mark.
    E.   District Court Proceedings
    As provided in 15 U.S.C. sec.
    1071(b)(1), CAE, Inc. appealed the TTAB’s
    decision to the district court ("Count
    V") and also asserted claims against
    Clean Air for trademark infringement
    ("Count I"), see 15 U.S.C. sec. 1114(1),
    unfair competition ("Count II"), see 15
    U.S.C. sec. 1125(a), and dilution under
    federal and state law ("Counts III and
    IV"), see 15 U.S.C. sec. 1125(c)(1) & 765
    ILCS 1035/15. Clean Air counterclaimed
    for a declaratory judgment affirming the
    TTAB’s decision ("Counterclaim I") and
    also asserted common law claims for
    unfair and predatory trademark use and
    tortious interference with prospective
    advantage ("Counterclaims II and III").
    In addition to presenting the
    evidentiary record from the TTAB
    proceeding, the parties submitted a
    substantial amount of new evidence to the
    district court./6 Clean Air’s new
    evidence provided an updated description
    of its products and services and
    reiterated that there was no evidence of
    any incidents of actual confusion. In
    contrast, the new evidence proffered by
    CAE, Inc. set out in greater detail the
    overlap, and potential overlap, between
    the two companies’ products and services.
    For example, CAE, Inc. pointed to Clean
    Air’s website materials, in which Clean
    Air stated:
    Our objective in working with our
    customers is to enhance both
    environmental and financial performance.
    How do we do this? Many who are
    unfamiliar with CAE may look at a list of
    our services and try to fit us into a
    predetermined niche. We hear this all the
    time--"Oh, you guys are the instrument
    rental company" or "Don’t you do scrubber
    optimizations?" or "I know you. You’re a
    stack testing company." The truth is that
    we do all these things and a lot more.
    But our strength, our uniqueness, lies
    not in our pieces but in the synergy that
    comes from bringing these pieces together
    into an integrated whole.
    R.38-2, Dale Dec., Ex.6 at 2 (emphasis in
    original). In addition, Clean Air
    publicizes on its website a "NEW ONLINE
    STORE" that gives customers access to
    products ranging in price from $1.75 to
    $11,150. 
    Id. at 4.
    Clean Air also
    proffered recent issues of the TAPPI
    Journal and Pulp & Paper. The 1998 Pulp &
    Paper Buyer’s Guide lists CAE Machinery,
    Ltd. and CAE Screenplates (both
    subsidiaries of CAE, Inc.) directly below
    Clean Air’s listing and also lists
    CAEExpress, a department of Clean Air.
    The new evidence before the district
    court further described CAE, Inc.’s
    forays into the field of environmental
    engineering. CAE, Inc. provided the
    district court with evidence that, in
    1973, it had adapted its SCADA technology
    to monitor stack emissions for the New
    Brunswick Electric Power Commission and
    that, in the early 1980s, the CIL/CAE
    joint venture offered "TOTAL TECHNOLOGY
    IN POLLUTION CONTROL," including stack
    analysis, system engineering,
    installation, scrubber and dust design,
    fabrication, and quality control, each of
    which were services similar, if not
    identical, to those offered by Clean Air.
    The new evidence also revealed that the
    parties offer, or have offered, other
    similar services, including: emissions
    testing; process engineering; flow
    modeling; optimization; and design,
    production, programming, and installation
    of SCADA systems.
    Also newly before the district court was
    an updated list of the industries to
    which both Clean Air and CAE, Inc. market
    and supply their products and services
    using the CAE mark; this list included
    the electric power generation, natural
    gas processing and petroleum refining,
    pulp and paper manufacturing,
    semiconductor, pharmaceutical and surface
    coating industries. CAE, Inc. provided
    the district court with a list of
    customers common to both companies, which
    included Northern States Power Company,
    Jacksonville Electric Authority, the
    United States Navy and Georgia Pacific
    Corporation. In addition, while CAE, Inc.
    acknowledged that none of its
    subsidiaries directly competed at that
    time with Clean Air in the measurement of
    smokestack emissions for regulatory
    compliance, CAE, Inc. informed the
    district court that its SCADA products
    and systems were fully capable of
    monitoring and controlling environmental
    variables such as smokestack emissions.
    CAE, Inc. also informed the court that it
    might easily begin to offer these
    services by adding appropriate monitoring
    and control equipment to existing SCADA
    systems.
    On the parties’ cross-motions for
    summary judgment as to Counts I, II and V
    of CAE, Inc.’s amended complaint, the
    district court discerned the main
    question with respect to all three counts
    to be whether there was a likelihood of
    confusion if Clean Air used a CAE mark
    similar to the CAE mark for which CAE,
    Inc. had federal trademark registration.
    Finding that a likelihood of confusion
    did exist, the district court granted
    summary judgment to CAE, Inc. on Counts
    I, II and V and on Counterclaim I,
    thereby reversing the TTAB’s decision and
    cancelling Clean Air’s registration of
    the CAE mark. The court also enjoined
    Clean Air from any future use of the CAE
    mark./7
    Clean Air moved for reconsideration. The
    district court adhered to its previous
    order, with the exception of entering
    judgment for CAE, Inc. on Clean Air’s
    Counterclaims II and III and modifying
    the injunction to permit Clean Air to use
    a CAE mark only when accompanied by a
    disclaimer of any affiliation with CAE,
    Inc. The court also ordered Clean Air to
    deliver to CAE, Inc. for destruction "any
    and all stationery, circulars, labels,
    advertising, packaging materials, plates,
    or other materials in its possession or
    under its control that contain" the CAE
    mark without the required disclaimer.
    R.60 at 2.
    On September 15, 2000, the district
    court denied Clean Air’s additional
    motions for post-judgment relief pursuant
    to Federal Rules of Civil Procedure 59(e)
    and 60(b)(2). In a separate order, also
    dated September 15, 2000, the district
    court granted Clean Air’s motion for a
    stay pending appeal only with respect to
    that part of the judgment requiring Clean
    Air to deliver to CAE, Inc. for
    destruction all materials containing the
    CAE mark without the required disclaimer.
    It denied Clean Air’s motions in all
    other respects. Clean Air filed a timely
    notice of appeal from the final judgment
    entered on August 4, 2000, and from the
    denial of post-judgment relief./8
    II
    DISCUSSION
    On appeal, Clean Air first contends that
    the district court reweighed all of the
    evidence in the record and thus applied
    the incorrect standard in reviewing the
    decision of the TTAB; Clean Air suggests
    that the district court should have
    applied de novo review only to the new
    evidence not presented to the TTAB.
    Second, Clean Air argues that the
    evidence does not support the district
    court’s finding that a likelihood of
    confusion exists.
    In response, CAE, Inc. maintains that,
    in light of the extensive new evidence
    introduced in the district court
    proceedings, the court applied the
    correct legal standard in reviewing the
    TTAB’s decision and the cross-motions for
    summary judgment. CAE, Inc. also argues
    that the undisputed facts support the
    district court’s likelihood-of-confusion
    determination.
    A.   The Lanham Act
    Congress passed the Lanham Act in 1946
    to "federalize" existing common law
    protection of trademarks used in
    interstate commerce. Peaches Enter. Corp.
    v. Repertoire Assocs., Inc., 
    62 F.3d 690
    ,
    692 (5th Cir. 1995). It established a
    federal right of action for trademark
    infringement to protect both consumer
    confidence in the quality and source of
    goods and businesses’ goodwill in their
    products. See generally 
    id. (discussing the
    Lanham Act’s purposes and basic
    scheme). The Lanham Act protects
    registered marks from interference by
    state legislation, prevents unfair
    competition and protects against
    fraudulent "use of reproductions, copies,
    counterfeits, or colorable imitations of
    registered marks." 15 U.S.C. sec. 1127;
    see also Eli Lilly & Co. v. Natural
    Answers, Inc., 
    233 F.3d 456
    , 461 (7th
    Cir. 2000). The Act created a federal
    register, which provided a public record
    of every registered trademark, service
    mark, collective mark and certification
    mark. See 15 U.S.C. sec.sec. 1051
    (registration application procedure),
    1052 (describing registerable
    trademarks); 3 J. Thomas McCarthy,
    Trademarks and Unfair Competition sec.
    19:2, at 19-11 (4th ed. 2001)
    (hereinafter "McCarthy"). Registration
    under the Act affords the registrant a
    rebuttable presumption of validity:
    [A] mark registered on the principal
    register . . . shall be prima facie
    evidence of the validity of the
    registered mark . . . and of the
    registrant’s exclusive right to use the
    registered mark in commerce on or in
    connection with the goods or services
    specified in the registration subject to
    any conditions or limitations stated
    therein, but shall not preclude another
    person from proving any legal or
    equitable defense or defect . . . which
    might have been asserted if such mark had
    not been registered.
    15 U.S.C. sec. 1115(a); see also 3
    McCarthy sec. 19:9, at 19-24.
    In order to be registered, a mark must
    be capable of distinguishing the
    applicant’s goods or services from those
    of others, see 15 U.S.C. sec. 1052, and
    must have been used in interstate
    commerce, see 15 U.S.C. sec.sec.
    1051(a)(1)(A) & 1127; see also Peaches
    Enter. 
    Corp., 62 F.3d at 692
    (noting that
    the Lanham Act protects trademarks used
    in interstate commerce). See generally 3
    McCarthy sec. 19:123, at 19-281 to 19-283
    (discussing the "in commerce"
    requirement). To obtain registration, the
    applicant must present certain facts in a
    verified written application to the
    United States Patent and Trademark Office
    ("PTO") and must pay a statutory filing
    fee. See 15 U.S.C. sec. 1051(a)(1). If,
    on review by a trademark examiner, it
    appears that the applicant is entitled to
    registration, the Commissioner of Patents
    and Trademarks publishes the mark in the
    PTO’s Official Gazette. See 15 U.S.C.
    sec. 1062(a). Upon publication, "[a]ny
    person who believes that he would be
    damaged by the registration" may file,
    within thirty days (along with the
    required fee), an opposition to the
    registration. 15 U.S.C. sec. 1063(a). If
    no successful opposition is made, the
    mark is registered and notice of the
    registration is published. See 15 U.S.C.
    sec. 1063(b)(1).
    If an opposition is filed, however, the
    parties are notified of a hearing before
    the TTAB, which determines and decides
    "the respective rights of registration."
    15 U.S.C. sec. 1067. Any party
    dissatisfied with the TTAB’s decision may
    appeal either to the United States Court
    of Appeals for the Federal Circuit or to
    a federal district court. See 15 U.S.C.
    sec. 1071; Am. Legion v. Matthew, 
    144 F.3d 498
    , 499 (7th Cir. 1998); 3 McCarthy
    sec. 21:20, at 21-25 to 21-26. In an
    appeal to the Federal Circuit, the case
    proceeds on the closed administrative
    record and no new evidence is permitted.
    See 15 U.S.C. sec. 1071(a)(4). In
    contrast, an appeal to the district court
    is both an appeal and a new action, which
    allows the parties to request additional
    relief and to submit new evidence. See
    Spraying Sys. Co. v. Delavan, Inc., 
    975 F.2d 387
    , 390 (7th Cir. 1992); 3 McCarthy
    sec. 21:20, at 21-26. The courts of
    appeals, other than the Federal Circuit,
    have appellate jurisdiction to review the
    district court’s decision. See 15 U.S.C.
    sec. 1121(a).
    Under the Lanham Act, a party may assert
    claims for, inter alia, trademark
    infringement, see 15 U.S.C. sec. 1114(1)
    (in this case, Count I), or unfair
    competition, see 15 U.S.C. sec. 1125(a)
    (in this case, Count II). To prevail on
    either claim, a plaintiff must establish
    that (1) its mark is protectable and (2)
    the defendant’s use of the mark is likely
    to cause confusion among consumers. See
    Eli 
    Lilly, 233 F.3d at 461
    ; Smith
    Fiberglass Prod., Inc. v. Ameron, Inc., 
    7 F.3d 1327
    , 1329 (7th Cir. 1993).
    Likelihood of confusion is also the
    central factual issue in reviewing a
    decision by the TTAB to sustain or
    dismiss opposition to a trademark
    registration. See Spraying 
    Sys., 975 F.2d at 392
    .
    B.   Standard of Review
    The district court’s decision involved
    both the entry of summary judgment and
    review of an agency decision: TTAB’s
    dismissal of CAE, Inc.’s opposition to
    Clean Air’s registration of CAE as a
    trademark. Thus, we first must determine
    which standard of review the district
    court should have applied to the TTAB’s
    decision.
    1. District Court’s Review of TTAB’s
    Decision
    We first determine which standard of
    review applies to a district court’s
    review of a TTAB decision, and we then
    evaluate whether the district court
    applied that standard in this case. As
    described above, the Lanham Act provides
    two avenues for review of TTAB decisions:
    review by the Federal Circuit on the
    closed record of the TTAB proceedings,
    see 15 U.S.C. sec. 1071(a)(4); or review
    by the district court with the option of
    presenting additional evidence and
    raising additional claims, see 15 U.S.C.
    sec. 1071(b)(1); see also Spraying 
    Sys., 975 F.2d at 390
    ; 3 McCarthy sec. 21:20,
    at 21-25 to 21-26. In the latter
    scenario, the district court sits in a
    dual capacity. It is an appellate
    reviewer of facts found by the TTAB and
    is also a fact-finder based on new
    evidence introduced to the court. See 3
    McCarthy, sec. 21:20, at 21-26. Although
    the district court’s review of the TTAB’s
    decision is considered de novo when the
    parties present new evidence and assert
    additional claims, the district court
    also must afford deference to the fact
    findings of the TTAB. See Spraying 
    Sys., 975 F.2d at 391
    ; 3 McCarthy sec. 21:21,
    at 21-27 to 21-28.
    The degree of deference that the
    district court must afford the TTAB’s
    findings of fact is a matter that
    recently has come under scrutiny. Before
    1999, a majority of courts, including
    this one, followed the thorough
    conviction standard established in Morgan
    v. Daniels, 
    153 U.S. 120
    , 125 (1894).
    Under that standard, the TTAB’s
    determination "’must be accepted as
    controlling upon a finding of fact about
    confusing similarity of trademarks,
    unless the contrary is established by
    testimony which in character and amount
    carries thorough conviction.’" Spraying
    
    Sys., 975 F.2d at 391
    (quoting Fleetwood
    Co. v. Hazel Bishop, Inc., 
    352 F.2d 841
    ,
    844 (7th Cir. 1965)); see also Material
    Supply Int’l, Inc. v. Sunmatch Indus.
    Co., 
    146 F.3d 983
    , 990 (D.C. Cir. 1998)
    (holding that the thorough conviction
    standard applies to review of the TTAB’s
    resolution of disputed issues of fact);
    Coach House Rest., Inc. v. Coach & Six
    Rest., Inc., 
    934 F.2d 1551
    , 1557 (11th
    Cir. 1991) (same); Wells Fargo & Co. v.
    Stagecoach Prop., Inc., 
    685 F.2d 302
    , 306
    (9th Cir. 1982) (same); Aloe Creme Lab.,
    Inc. v. Tex. Pharmacal Co., 
    335 F.2d 72
    ,
    74 (5th Cir. 1964) (same); Wilson Jones
    Co. v. Gilbert & Bennett Mfg. Co., 
    332 F.2d 216
    , 218 (2d Cir. 1964) (same);
    Century Distilling Co. v. Continental
    Distilling Co., 
    106 F.2d 486
    , 489 (3d
    Cir. 1939) (same); 3 McCarthy sec. 21:22,
    at 21-29 to 21-30 (noting that, before
    1999, most courts used Morgan’s "thorough
    conviction" standard); but cf. On-Line
    Careline, Inc. v. Am. Online, Inc., 
    229 F.3d 1080
    , 1084 (Fed. Cir. 2000) (noting
    that, in the Federal Circuit before 1999,
    TTAB questions of fact were reviewed for
    clear error). Under the majority rule,
    the district court reviewed de novo any
    new evidence presented, but it weighed
    that evidence against the TTAB’s findings
    under the "thorough conviction" standard.
    Spraying 
    Sys., 975 F.2d at 391
    .
    In 1999, however, the Supreme Court held
    in Dickinson v. Zurko, 
    527 U.S. 150
    (1999), that the proper standard of judi
    cial review of findings of fact made by
    the PTO is not the stricter "clearly
    erroneous" standard but rather the
    slightly more deferential standard of the
    Administrative Procedure Act ("APA"), 5
    U.S.C. sec. 706./9 
    Zurko, 527 U.S. at 165
    . Section 706 of the APA sets forth
    the standards governing the scope of
    judicial review of agency factfinding:
    The reviewing court shall--
    . . .
    (2) hold unlawful and set aside agency .
    . . findings . . . found to be--
    (A) arbitrary, capricious, [or] an abuse
    of discretion, or . . .
    . . .
    (E) unsupported by substantial evidence
    in a case subject to sections 556 and 557
    of this title or otherwise reviewed on
    the record of an agency hearing provided
    by statute . . . .
    In making the foregoing determinations,
    the court shall review the whole record
    or those parts of it cited by a party. .
    . .
    5 U.S.C. sec. 706. Although the Court
    left open the question of which APA
    standard applied--"arbitrary, capricious,
    or abuse of discretion" under sec.
    706(2)(A) or "substantial evidence" under
    sec. 706(2)(E)--the Federal Circuit has
    concluded that, after Zurko, it will
    review TTAB findings of fact for
    substantial evidence. See On-Line
    
    Careline, 229 F.3d at 1085
    . "Substantial
    evidence is more than a mere scintilla.
    It means such relevant evidence as a
    reasonable mind might accept as adequate
    to support a conclusion." Consol. Edison
    Co. v. NLRB, 
    305 U.S. 197
    , 229 (1938).
    This court has yet to interpret and to
    apply Zurko, which went unnoticed by the
    district court and the parties in this
    case. Clean Air contends, however, that,
    in the absence of "credible . . .
    material factual evidence" that the
    TTAB’s findings were clearly erroneous,
    the district court erred in "reweighing"
    the evidence in the administrative
    record. Appellant’s Br. at 7 & 8. On the
    other hand, CAE, Inc. maintains that, in
    light of the "extensive new evidence"
    presented in the district court
    proceedings, the court correctly applied
    the thorough conviction standard to the
    TTAB’s factfinding. Appellee’s Br. at 15.
    We cannot accept either of these
    contentions. After Zurko, it is clear
    that neither the clearly erroneous nor
    the thorough conviction standard apply;
    instead, Zurko instructs that we must
    apply the APA when reviewing agency
    factfinding. See 
    Zurko, 527 U.S. at 165
    .
    In addition, we agree with the Federal
    Circuit’s resolution of the question left
    open in Zurko as to which prong of sec.
    706(2) applies. When a court’s review of
    an agency’s factfinding is circumscribed
    by the agency record, as the Federal
    Circuit explained, the substantial
    evidence standard in sec. 706(2)(E)
    applies. See In re Gartside, 
    203 F.3d 1305
    , 1312-15 (Fed. Cir. 2000); see also
    
    Zurko, 527 U.S. at 164
    (noting that if an
    agency’s decision is "bound up with a
    record-based factual conclusion," the
    reviewing court applies the substantial
    evidence standard); On-Line 
    Careline, 229 F.3d at 1085
    (reviewing TTAB factfinding
    for substantial evidence); Recot, Inc. v.
    M.C. Becton, 
    214 F.3d 1322
    , 1327 (Fed.
    Cir. 2000) (same). Cf. 6 West Ltd. Corp.
    v. NLRB, 
    237 F.3d 767
    , 777 (7th Cir.
    2001) (applying the substantial evidence
    standard to finding of fact made by the
    National Labor Relations Board); Powers
    v. Apfel, 
    207 F.3d 431
    , 434 (7th Cir.
    2000) (Social Security Administration);
    Malek v. INS, 
    198 F.3d 1016
    , 1021 (7th
    Cir. 2000) (Board of Immigration
    Appeals); Hoffman Homes, Inc. v.
    Administrator, U.S. EPA, 
    999 F.2d 256
    ,
    261 (7th Cir. 1993) (Environmental
    Protection Agency); Kraft, Inc. v. FTC,
    
    970 F.2d 311
    , 316-18 (7th Cir. 1992)
    (Federal Trade Commission); Stanley v.
    Bd. of Governors of Fed. Reserve Sys.,
    
    940 F.2d 267
    , 272 (7th Cir. 1991)
    (Federal Reserve Board). We see no need
    to depart from that rule here.
    Accordingly, we conclude that findings of
    fact by the TTAB properly are reviewed
    under the substantial evidence standard
    set forth in sec. 706(2)(E) of the APA.
    Accord On-Line 
    Careline, 229 F.3d at 1085
    .
    The district court did not have the
    benefit of this clarification at the time
    it rendered its decision; therefore, we
    must determine whether, in substance, the
    district court’s review of the TTAB’s
    decision was consistent with Zurko. At
    the beginning of its analysis, the
    district court recognized that its review
    of the newly presented evidence was de
    novo, but it also acknowledged that the
    TTAB’s factfinding was controlling
    "’unless the contrary is established by
    testimony which in character and amount
    carries thorough conviction.’" R.49 at 16
    (quoting Spraying 
    Sys., 975 F.2d at 391
    ).
    The court first outlined the newly
    presented evidence and then, with
    reference to the TTAB’s findings,
    discussed how that evidence required a
    different conclusion than that reached by
    the TTAB. In conclusion, the court stated
    that it had "given deference to the
    [TTAB’s] decision and [was] still left
    with a firm, thorough conviction that the
    [TTAB’s] decision was incorrect." R.49 at
    25. Thus, the district court did not
    apply the clearly erroneous standard
    rejected by the Supreme Court in Zurko,
    but rather applied the "meaningful
    review" required by the APA. 
    Zurko, 527 U.S. at 162
    . The district acted as a
    fact-finder with respect to the new
    evidence and factors not discussed by the
    TTAB, see 
    id. at 164,
    while also
    affording deference to the TTAB’s
    findings. Therefore, although the
    district court did not formally apply the
    substantial evidence standard now
    required by Zurko, the court applied that
    standard in substance, and it did not
    commit reversible error with respect to
    the standard of review./10
    2. Appellate Review of the District
    Court’s Decision
    This court reviews de novo the district
    court’s decision to grant summary
    judgment. See Albiero v. City of
    Kankakee, 
    246 F.3d 927
    , 931 (7th Cir.
    2001). Summary judgment is appropriate
    when the "pleadings, depositions, answers
    to interrogatories, and admissions on
    file, together with the affidavits, if
    any, show that there is no genuine issue
    as to any material fact and that the
    moving party is entitled to a judgment as
    a matter of law." Fed. R. Civ. P. 56(c).
    "Factual disputes are ’genuine’ only ’if
    the evidence is such that a reasonable
    jury could return a verdict for the
    [nonmovant],’" and are "’material’ only
    when they ’might affect the outcome of
    the suit under the governing law.’" Oest
    v. Ill. Dep’t of Corrections, 
    240 F.3d 605
    , 610 (7th Cir. 2001) (quoting
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 248 (1986)). Thus, in ruling on a
    summary judgment motion, the district
    court "must decide ’whether the evidence
    presents a sufficient disagreement to
    require submission to a jury or whether
    it is so one-sided that one party must
    prevail as a matter of law.’" 
    Id. (quoting Liberty
    Lobby, 477 U.S. at 251
    -
    52).
    In reviewing the district court’s
    decision, "we must construe all facts in
    the light most favorable to the non-
    moving party and draw all reasonable and
    justifiable inferences in favor of that
    party." Bellaver v. Quanex Corp., 
    200 F.3d 485
    , 491-92 (7th Cir. 2000). The
    nonmovant may not rest on the pleadings
    but must adduce evidence "set[ting] forth
    specific facts showing that there is a
    genuine issue for trial." Fed. R. Civ. P.
    56(e). The nonmovant must create more
    than mere doubt as to the material facts
    and will not prevail by relying on a mere
    scintilla of evidence to support its
    position. See Liberty 
    Lobby, 477 U.S. at 252
    ; 
    Albiero, 246 F.3d at 932
    .
    In a trademark infringement case,
    whether consumers are likely to be
    confused about the origin of a company’s
    products is a question of fact, and,
    ordinarily, we would review the district
    court’s finding of fact for clear error.
    See Smith Fiberglass 
    Prod., 7 F.3d at 1329
    ; 3 McCarthy sec. 23:73, at 23-189.
    Although disputed questions of fact may
    prevent summary judgment in certain
    instances, the question of whether
    likelihood of confusion exists may be
    resolved on summary judgment "if the
    evidence is so one-sided that there can
    be no doubt about how the question should
    be answered." Door Sys., Inc. v. Pro-Line
    Door Sys., Inc., 
    83 F.3d 169
    , 173 (7th
    Cir. 1996) (affirming summary judgment
    for the defendant when there was "no
    reasonable likelihood that any
    significant number of consumers could
    mistake the defendant for the
    plaintiff"). Thus, the district court’s
    grant of summary judgment for CAE, Inc.
    constitutes a finding that, even
    resolving all factual disputes in favor
    of Clean Air, there is a likelihood of
    confusion as a matter of law. We review
    this legal conclusion de novo. See Kohler
    Co. v. Moen, Inc., 
    12 F.3d 632
    , 633-34
    (7th Cir. 1993); Sands, Taylor & Wood Co.
    v. Quaker Oats Co., 
    978 F.2d 947
    , 951-52
    (7th Cir. 1992). In addition, this court
    reviews the district court’s application
    of the likelihood of confusion analysis
    to determine if it "’was infected with
    legal error, i.e., an erroneous general
    principle about the way the test should
    be applied.’" Dorr-Oliver, Inc. v. Fluid-
    Quip, Inc., 
    94 F.3d 376
    , 380 (7th Cir.
    1996) (quoting Forum Corp. of N. Am. v.
    Forum, Ltd., 
    903 F.2d 434
    , 438 (7th Cir.
    1990)). With these standards of review in
    mind, we turn to the merits of the
    parties’ claims.
    B.   Likelihood of Confusion/11
    Seven factors comprise the likelihood of
    confusion analysis: (1) similarity
    between the marks in appearance and
    suggestion; (2) similarity of the
    products; (3) the area and manner of
    concurrent use; (4) the degree of care
    likely to be exercised by consumers; (5)
    the strength of the plaintiff’s mark; (6)
    whether actual confusion exists; and (7)
    whether the defendant intended to "palm
    off" his product as that of the
    plaintiff. Ty, Inc. v. Jones Group, Inc.,
    
    237 F.3d 891
    , 897-98 (7th Cir. 2001); see
    also Barbecue Marx, Inc. v. 551 Ogden,
    Inc., 
    235 F.3d 1041
    , 1043-44 (7th Cir.
    2000). "The likelihood of confusion test
    is an equitable balancing test." Barbecue
    
    Marx, 235 F.2d at 1044
    . No single factor
    is dispositive and courts may assign
    varying weights to each of the factors
    depending on the facts presented. See 
    id. In many
    cases, however, three of the
    factors are likely to be particularly
    important: the similarity of the marks,
    the defendant’s intent, and actual
    confusion. See 
    id. 1. Similarity
    of the Marks
    As both the TTAB and the district court
    found, the CAE mark that Clean Air sought
    to register is indistinguishable from the
    block-letter CAE mark that has been
    registered by CAE, Inc. since 1972. Both
    parties use the CAE mark in connection
    with the products and services they
    offer. Indeed, Clean Air itself concedes
    that the marks are "virtually identical."
    Appellant’s Br. at 17. Accordingly, there
    is no genuine issue of material fact
    about the similarity of the marks, and
    this factor weighs in favor of finding a
    likelihood of confusion.
    2.   Similarity of the Products
    The second factor is the similarity of
    the products bearing the CAE mark. The
    TTAB found that the products and services
    for which Clean Air sought registration
    were "quite distinct" from the products
    and services specified in CAE, Inc.’s
    trademark registrations. R.34, Ex.4 at 5.
    The TTAB relied heavily on its findings
    that CAE, Inc. never provided the
    services for which Clean Air sought
    registration, i.e., "technical
    consultation, testing, research and
    engineering in the field of environmental
    processes," and that CAE, Inc. presently
    does not offer environmental engineering
    services or environmental consulting
    services to its customers. 
    Id. at 6.
      The district court disagreed with the
    TTAB’s assessment. It found that the
    parties’ products and services do overlap
    at least insofar as "both parties offer,
    under the CAE name, process engineering
    and data acquisition systems, equipment,
    and services to companies involved in
    industrial processes." R.49 at 18. It
    found further that this overlap was
    likely to confuse consumers. The district
    court also believed that the diverse
    nature of CAE, Inc.’s businesses made "it
    likely that consumers might reasonably
    expect CAE, Inc. to expand its business
    to offer the same products and services
    offered by Clean Air." 
    Id. at 19.
    On appeal, Clean Air emphasizes certain
    of its products and services, specific to
    the field of environmental consulting and
    engineering, that differ from those
    offered by CAE, Inc., and it asserts that
    the parties are not, and never have been,
    in direct competition. Thus, Clean Air
    maintains, the district court erred in
    finding an overlap among the parties’
    products and services because there was
    "overwhelming" evidence to support the
    TTAB’s finding of an absence of overlap.
    Appellant’s Br. at 18. CAE, Inc. contends
    that the district court correctly found
    similarity, in particular between the
    parties’ products and services related to
    process engineering, and a likelihood
    that CAE, Inc. could and would expand
    into additional services currently
    offered by Clean Air.
    Although, as the district court noted,
    many of the products and services offered
    by the parties are "quite different,"
    R.49 at 18, this dissimilarity is not
    dispositive of the likelihood of
    confusion inquiry. A likelihood of
    confusion may exist even if the parties
    are not in direct competition, see Forum
    
    Corp., 903 F.2d at 442
    , or their products
    and services are not identical, see
    McGraw-Edison Co. v. Walt Disney Prod.,
    
    787 F.2d 1163
    , 1169 (7th Cir. 1986).
    Rather, because the rights of an owner of
    a registered trademark extend to any
    goods that might be, in the minds of
    consumers, "related," i.e., put out by a
    single producer, the more accurate
    inquiry is whether the public is likely
    to attribute the products and services to
    a single source. See 
    McGraw-Edison, 787 F.2d at 1169
    . "Closely related" products
    are those that "would reasonably be
    thought by the buying public to come from
    the same source, or thought to be
    affiliated with, connected with, or
    sponsored by, the trademark owner."
    Sands, Taylor & 
    Wood, 978 F.2d at 958
    (internal citations and quotation marks
    omitted); see also Int’l Kennel Club of
    Chicago, Inc. v. Mighty Star, Inc., 
    846 F.2d 1079
    , 1089 (7th Cir. 1988) (holding
    that a likelihood of confusion existed
    when the products were not identical but
    were sufficiently related to create an
    inference in consumers’ minds that the
    products came from the same source).
    a.   Current Goods and Services
    To support its argument that no overlap
    exists between the parties’ products and
    services, Clean Air relies heavily on the
    admissions of several of CAE, Inc.’s
    employees that, at present, CAE, Inc.
    does not provide technical consultation,
    testing, research or engineering in the
    field of environmental processes, for
    which Clean Air sought registration, nor
    does it provide equipment for air
    pollution testing and monitoring. As the
    district court found based on the newly
    presented evidence, however, the
    undisputed facts show that the parties do
    offer some of the same products and
    services. Both offer, under the CAE name,
    process engineering and data acquisition
    systems, equipment, and services to
    companies with industrial processes.
    Process engineering includes SCADA
    systems, which both parties market to
    their customers (many of whom are the
    same) for the purpose of making existing
    equipment work more efficiently and
    making operators perform more
    efficiently, thereby increasing profits.
    Both companies’ process engineering
    technologies have applications in the
    same industries: pulp and paper, electric
    power, natural gas processing and
    petroleum refining, semiconductor,
    pharmaceutical and surface coating. In
    addition, Clean Air markets software that
    can be used as an add-on or upgrade for
    a SCADA system, including those SCADA
    systems designed and built by CAE, Inc.
    Thus, the district court correctly
    concluded that the undisputed facts
    demonstrated that Clean Air’s use of a
    mark identical to that registered by CAE,
    Inc. in connection with closely related
    products and services is likely to cause
    confusion. See Sands, Taylor & 
    Wood, 978 F.2d at 958
    -61 (holding that the
    defendant’s use of the plaintiff’s mark
    to market a similar isotonic beverage was
    likely to cause confusion); Scandia Down
    Corp. v. Euroquilt, Inc., 
    772 F.2d 1423
    ,
    1431 (7th Cir. 1985) (holding that
    Euroquilt’s use of a similar mark in
    connection with similar products-- down
    bedding--was likely to cause confusion).
    Even taking as true Clean Air’s
    assertion that it offers different
    process engineering services for
    different purposes, this would not refute
    the district court’s finding that
    consumers are likely to be confused by
    Clean Air’s use of the CAE mark. In
    McGraw-Edison, for example, we held that
    the district court should have considered
    the question of whether the purchasing
    public might believe that a single source
    produced both McGraw Edison’s electronic
    fuses and Disney’s video games. See
    
    McGraw-Edison, 787 F.2d at 1169
    . Because
    McGraw-Edison’s fuses were "compatible
    and consistent" with the electrical and
    electronic products marketed by Disney,
    the products were not entirely unrelated
    and consumers reasonably could attribute
    the fuses and the video games to the same
    source. 
    Id. As in
    McGraw-Edison, the likelihood of
    confusion about the source in this case
    arises from the relatedness of the
    products and services. For example, one
    of the products listed in CAE, Inc.’s
    trademark registration is "supervisory
    control, test and data logging equipment
    and systems," R.34, Ex.4 at 4; among the
    services Clean Air markets to its
    customers under the CAE mark are
    designing and building data acquisition
    systems and control equipment and making
    existing equipment work more efficiently.
    In addition to these general
    similarities, specific similarities exist
    as well. Clean Air markets its SCADA
    systems for monitoring air quality and
    emissions. CAE, Inc. designed a SCADA
    system in 1973 for the New Brunswick
    Power Commission’s stack emissions
    monitoring operation, and it advertised
    stack emissions testing services in
    connection with its CIL/CAE venture in
    the early 1980s. Moreover, Clean Air’s
    development and marketing of SCADA
    software and components that are
    complementary to CAE, Inc.’s SCADA
    products increase the likelihood of
    confusion. See Fuji Photo Film Co. v.
    Shinohara Shoji Kabushiki Kaisha, 
    754 F.2d 591
    , 598 (5th Cir. 1985) (explaining
    that complementary products in particular
    are susceptible to confusion). None of
    this evidence was before the TTAB when it
    found that no likelihood of confusion
    existed.
    Because the new evidence demonstrated
    that Clean Air and CAE, Inc. offer some
    closely-related, if not substantially
    similar, products and services under the
    CAE mark, the district court correctly
    found that consumers reasonably could
    conclude that Clean Air’s products and
    services are affiliated or associated
    with CAE, Inc. See Ty, 
    Inc., 237 F.3d at 900
    (holding that similarities between
    the defendant’s "Beanie Racers" and Ty,
    Inc.’s "Beanie Babies" could cause the
    public to believe that the defendant’s
    products were affiliated or associated
    with Ty, Inc.); Int’l Kennel 
    Club, 846 F.2d at 1089
    (holding that the
    similarities between the parties’
    products were significant enough that the
    public might attribute both products to a
    single source).
    b. Expansion Into Other Products and
    Services
    Clean Air also objects to the district
    court’s finding that "the diverse nature
    of CAE, Inc.’s businesses makes it likely
    that consumers might reasonably expect
    CAE, Inc. to expand its business to offer
    the same products and services offered by
    Clean Air" in the air pollution control
    business. R.49 at 19. The court based its
    finding on undisputed evidence that: (1)
    CAE, Inc. is a large, multinational
    conglomerate that currently offers
    products and services related to data
    acquisition, flow modeling, and process
    engineering to industrial companies; (2)
    two of CAE, Inc.’s major competitors, ABB
    and Siemens, currently offer air quality
    services that overlap with some of Clean
    Air’s products and services; and (3) CAE,
    Inc. has been involved in the air
    pollution control business, in particular
    through the CIL/CAE joint venture that
    offered "TOTAL TECHNOLOGY IN POLLUTION
    CONTROL" in the 1980s. No evidence of ei
    ther (2) or (3) was introduced in the
    TTAB proceeding.
    Courts have recognized that an important
    reason to protect trademark owners
    against the use of similar marks on
    closely related products is "to protect
    the owner’s ability to enter product
    markets in which it does not now trade
    but into which it might reasonably be
    expected to expand in the future." Sands,
    Taylor & 
    Wood, 978 F.2d at 958
    . The
    Lanham Act aims to protect "the trademark
    owner’s interest in capitalizing on the
    good will associated with its mark by
    moving into new markets." 
    Id. This protection
    is warranted here, where CAE,
    Inc. has been involved in the air
    pollution control business, currently
    markets its products and services to
    companies and industries subject to
    environmental regulations, and competes
    with two companies who offer air
    pollution services similar to Clean Air.
    These circumstances demonstrate the
    convergence of the technologies of CAE,
    Inc. and Clean Air as well as an
    industrial affinity between their
    products and services that is likely to
    increase consumer confusion if both
    parties market their products and
    services in connection with the same CAE
    mark. See Int’l Kennel 
    Club, 846 F.2d at 1089
    (concluding that it would be logical
    for consumers to conclude that the
    plaintiff kennel club would branch out
    into marketing "pedigree" toy dogs).
    In analyzing the similarity of products
    and services, the district court gave
    "due deference" to the TTAB’s finding of
    dissimilarity. R.49 at 19. But, the
    district court had before it new evidence
    that CAE, Inc.: (1) had past experience
    in the air pollution business through the
    CIL/CAE joint venture and in connection
    with the New Brunswick Power Authority
    Project; (2) had been involved in other
    areas of pollution control through its
    FRP pipe businesses; (3) possessed the
    ability to configure its current products
    for application in the pollution control
    business; (4) marketed its products and
    services to the same companies that Clean
    Air marketed its environmental
    engineering services; and (5) competed
    with two companies that offered products
    and services substantially similar to
    those offered by Clean Air. All of this
    new evidence was subject to the district
    court’s de novo review, and it supported
    the court’s conclusion that the
    similarity of the parties’ products and
    services weighed in favor of a finding of
    likelihood of confusion.
    3.   Area and Manner of Concurrent Use
    The third factor in the likelihood of
    confusion analysis assesses "whether
    there is a relationship in use,
    promotion, distribution, or sales between
    the goods or services of the parties."
    
    Forum, 903 F.2d at 442
    . Although the TTAB
    did not address this factor in its
    decision, the district court found that
    the parties use the CAE mark in the same
    manner and display the CAE mark in the
    same channels of commerce. The undisputed
    evidence supports the district court’s
    conclusion that this factor weighs in
    favor of a finding that a likelihood of
    confusion exists.
    First, it is undisputed that the manner
    in which the parties use the CAE mark is
    similar because both parties use CAE as
    the first component of the names of their
    subsidiaries and departments: CAE
    Machinery, CAE Express, CAE Screenplates,
    CAE Diagnostics, CAE Instrument Rentals,
    CAE Source Testing, CAE Combustion, etc.
    Without prior knowledge, it is virtually
    impossible for consumers to distinguish
    which names are attributable to CAE, Inc.
    and which are attributable to Clean Air.
    Second, Clean Air does not dispute that
    it has displayed and continues to display
    the CAE mark in the same channels of
    commerce as CAE, Inc. CAE, Inc. and Clean
    Air agree that they have targeted the
    same general audience (companies with
    industrial processes) and some of the
    same specific industries, such as pulp
    and paper, electric power, natural gas
    processing, petroleum refining,
    semiconductor, pharmaceutical and surface
    coating. See Ty, 
    Inc., 237 F.3d at 901
    (holding that the area of concurrent use
    overlapped when the parties sold their
    products in the same stores, advertised
    in the same magazines, and targeted the
    same general audience). In fact, as seen
    in the new evidence not presented to the
    TTAB, CAE, Inc. and Clean Air have
    marketed and sold their goods and
    services to dozens of the same companies
    and entities, including Gaylord
    Container, Westvaco, Georgia Pacific,
    Dupont, Owens Corning, Phillip Morris and
    Weyerhauser. The parties employ similar
    marketing procedures, including personal
    meetings with a direct sales force,
    direct mailings, advertisements in trade
    journals and exhibitions, and appearances
    at trade shows and conferences. See
    
    Forum, 903 F.2d at 441-42
    (holding that
    concurrent use existed when both parties
    marketed and sold products through a
    direct sales force, direct mailings, and
    attendance at the same trade show). In
    particular, both CAE, Inc. and Clean Air
    regularly have attended the TAPPI trade
    show for the pulp and paper industry and
    have advertised in the TAPPI Journal and
    Pulp & Paper. See Ty, 
    Inc., 237 F.3d at 901
    . The advertiser index of Pulp & Paper
    has listed "CAE Clean Air Engineering"
    directly above the listing for "CAE
    Screenplates" and directly below the
    listing for "CAE Machinery, Ltd.," both
    of which are subsidiaries of CAE, Inc.
    and are entirely unrelated to Clean Air.
    The manufacturers and suppliers directory
    for the 1998 Pulp and Paper Buyer’s Guide
    also listed CAE Machinery, Ltd. and CAE
    Screenplates directly below the listing
    for Clean Air. In light of the
    substantial new evidence before the
    district court relating to the parties’
    promotional and advertising efforts and
    the TTAB’s failure to make a finding as
    to this factor, the district court was
    entitled to review this evidence de novo
    and to conclude, correctly we believe,
    that the undisputed facts demonstrate
    that Clean Air and CAE, Inc. sell and
    market their products and services
    through many of the same channels.
    Therefore, this factor weighs in favor of
    a finding of likelihood of confusion.
    4. Degree of Care Likely to Be Exercised
    by Consumers
    To assess properly the degree of
    consumer care, the court must consider
    both parties’ potential consumers,
    because even those consumers who buy only
    CAE, Inc.’s products and services could
    be confused as to the source of those
    products or services. See 
    Forum, 903 F.2d at 442
    ; Fuji Photo 
    Film, 754 F.2d at 596
    (explaining that the Lanham Act’s
    prohibition of trademark infringement
    "clearly encompasses confusion on the
    part of purchasers of either (or both)
    party’s products") (emphasis in
    original). The TTAB held that this factor
    weighed against a finding of likelihood
    of confusion because both parties’
    products and services were "quite
    expensive" and were "offered only to
    sophisticated commercial buyers (as
    opposed to ordinary consumers), usually
    after extensive negotiations." R.34, Ex.4
    at 9. Notwithstanding the sophistication
    of many of the parties’ customers, the
    district court found, based on additional
    new evidence, that there was a real
    likelihood of confusion because Clean Air
    sold products ranging in price from $1.75
    to $11,150 via the internet, telephone
    and catalogues.
    The district court did not err in
    concluding that the nature and
    sophistication of the parties’ customers
    increased the likelihood of confusion.
    First, although many of the parties’
    customers are sophisticated and decide to
    buy only after extensive negotiations,
    these customers’ technical sophistication
    about their particular industry does not
    equate to trademark sophistication. See
    Fuji Photo 
    Film, 754 F.2d at 595
    (explaining that, even though consumers
    of printing presses were sophisticated
    and did not buy on impulse, those factors
    were not determinative). As the
    undisputed facts show, the parties’
    products and services already overlap,
    particularly with respect to process
    engineering and SCADA systems, and will
    overlap to an even greater degree if they
    expand to offer new products, as Clean
    Air recently has done by developing
    software for SCADA systems and as CAE,
    Inc. is capable of doing by adapting its
    current technology for further use in the
    pollution control field. This convergence
    of the parties’ technologies makes it
    more likely that even an informed and
    sophisticated consumer will mistakenly
    attribute the parties’ products and
    services to a common source. The
    potential for such mistakes is heightened
    by the difficulty of determining which
    CAE entity belongs to which party without
    some prior knowledge of each party’s
    corporate structure.
    Second, the district court gave
    appropriate weight to new evidence that
    demonstrated that Clean Air offers a wide
    variety of low-priced goods through its
    catalogue and on the Internet. The more
    widely accessible and inexpensive the
    products and services, the more likely
    that consumers will exercise a lesser
    degree of care and discrimination in
    their purchases. See 
    id. at 596
    (stating
    that the simplicity and negligible cost
    of Fuji’s goods and its extensive
    advertising increased the likelihood of
    confusion about the source of the goods).
    Third, in addition to point-of-sale
    confusion about the source of products
    and services, we have recognized that the
    Lanham Act’s protections also extend to
    post-sale confusion of potential
    customers. 
    Dorr-Oliver, 94 F.3d at 381-82
    (explaining post-sale confusion and
    quoting Lois Sportswear, U.S.A., Inc. v.
    Levi Strauss & Co., 
    799 F.2d 867
    , 872-73
    (2d Cir. 1986)). Post-sale confusion
    refers to a situation in which, for
    example, a potential customer sees a
    product bearing the label "CAE Rental
    Equipment" without reference to Clean Air
    and, consistent with the customer’s
    familiarity with CAE, Inc., mistakenly
    attributes the products to CAE, Inc.,
    thereby influencing his buying decision,
    either positively or negatively. See 
    id. at 381-82.
    That association constitutes
    infringement of CAE, Inc.’s registered
    trademark. See id.; see also Lois
    
    Sportswear, 799 F.2d at 872-73
    (explaining that, although product labels
    informed actual buyers in the store about
    the source of the plaintiff’s jeans,
    similarity in the stitching patterns
    could cause prospective buyers who saw
    the jeans outside the store to associate
    the defendant’s jeans with the plaintiff,
    thereby influencing their buying
    decision).
    Finally, the district court correctly
    distinguished on their facts the two
    cases relied on by the TTAB. In Dynamics
    Research Corp. v. Langenau Manufacturing
    Co., 
    704 F.2d 1575
    (Fed. Cir. 1983), the
    court affirmed the TTAB’s finding that
    there was no likelihood of confusion
    because, although the parties both used
    the mark "DRC," they sold entirely
    different products (appellant sold gauges
    for press brakes and appellee sold sheet
    metal fabric) to different companies in
    different industries. Dynamics 
    Res., 704 F.2d at 1576-78
    . In contrast, the
    undisputed evidence here shows that CAE,
    Inc. and Clean Air offer some of the same
    basic technology and, in some instances,
    serve the same companies and the same
    industries; therefore, Dynamics is not
    persuasive. Likewise, the Federal
    Circuit’s determination that confusion
    was unlikely in Electronic Design &
    Sales, Inc. v. Electronic Data Systems
    Corp., 
    954 F.2d 713
    (Fed. Cir. 1992),
    rested on the TTAB’s failure to consider
    all seven factors in the likelihood of
    confusion analysis and on
    significantdifferences between the
    parties’ products. The plaintiff used the
    "EDS" mark to advertise its power
    supplies and battery chargers, whereas
    the defendant used the "EDS" mark in
    connection with its computer services.
    Electronic Design & 
    Sales, 954 F.2d at 717-19
    . Thus, the lack of an overlap
    between the parties’ products and
    services in Electronic Design & Sales
    renders its holding unpersuasive in this
    case as well.
    The district court, although affording
    deference to the TTAB’s finding as to
    consumer sophistication, also looked at
    newly presented evidence of the broad
    availability of Clean Air’s products,
    some of which are inexpensive. The court
    reviewed evidence of an overlap in the
    companies that currently consume both
    parties’ products and services. The court
    also considered evidence of the parties’
    converging technologies, which increases
    the potential for further overlap in the
    future as the parties expand their
    businesses. This application of the
    fourth factor of the likelihood of
    confusion analysis was a correct
    application of the law. The undisputed
    evidence in the record supports the
    court’s factual finding that consumer
    sophistication did not diminish the
    likelihood of confusion.
    5.   The Strength of CAE, Inc.’s Mark
    The "strength" of a trademark refers to
    the mark’s distinctiveness, meaning its
    propensity to identify the products or
    services sold as emanating from a
    particular source. See Eli 
    Lilly, 233 F.3d at 464
    ; Sands, Taylor & 
    Wood, 978 F.2d at 959
    (quoting McGregor-Doniger,
    Inc. v. Drizzle, Inc., 
    599 F.2d 1126
    ,
    1131 (2d Cir. 1979)). The TTAB did not
    address the relative strength of CAE,
    Inc.’s registered CAE mark, but the
    district court concluded that CAE, Inc.
    has a "strong, distinctive mark." R.49 at
    23.
    Trademark law recognizes five categories
    of trademarks, in ascending order of
    distinctiveness: generic, descriptive,
    suggestive, arbitrary and fanciful. See
    Two Pesos, Inc. v. Taco Cabana, Inc., 
    505 U.S. 763
    , 768 (1992) (adopting Judge
    Friendly’s formulation in Abercrombie &
    Fitch Co. v. Hunting World, Inc., 
    537 F.2d 4
    , 9-11 (2d Cir. 1976)). The CAE
    mark is an unpronounceable set of letters
    and thus falls into the category of
    letter marks generally accorded broader
    trademark protection because "it is more
    difficult to remember a series of
    arbitrarily arranged letters than it is
    to remember words, figures, phrases, or
    syllables." 3 McCarthy sec. 23:33, at 23-
    97; see also Edison Bros. Stores, Inc. v.
    Brutting E.B. Sport-Int’l GmbH, 230
    U.S.P.Q. 530, 533 (TTAB 1986) (referring
    to the "well-established principle" of
    trademark law that confusion is more
    likely between "arbitrarily arranged
    letters" than other categories of marks).
    This principle is particularly applicable
    here because the letters CAE appear
    without reference to the underlying words
    from which they were originally derived--
    Canadian Aviation Electronics. See Weiss
    Assoc., Inc. v. HRL Assoc., Inc., 
    902 F.2d 1546
    , 1548 (Fed. Cir. 1990)
    (invoking this principle and finding a
    likelihood of confusion between TMS and
    TMM for competitive specialized computer
    software).
    In addition to the fact that the CAE
    mark is an unpronounceable set of
    letters, the district court based its
    finding of the strength of CAE, Inc.’s
    mark on the company’s: (1) 40-year use of
    the mark in the United States; (2)
    hundreds of millions of dollars of annual
    sales in the United States; (3) extensive
    expenditures to promote its products and
    services in connection with the CAE mark;
    (4) use of the letters in the names of
    its subsidiaries and divisions; and (5)
    registration of several federal
    trademarks that feature the letter
    combination. Clean Air disputes the
    district court’s conclusion, pointing to
    seven registrations of the CAE mark by
    companies other than CAE, Inc., and
    arguing that CAE, Inc. is attempting to
    "monopolize" the CAE mark for all
    purposes. Appellant’s Br. at 22. As CAE,
    Inc. points out, however, six of these
    registrations are cancelled and thus are
    not evidence of third party use that
    would weaken CAE, Inc.’s mark. See
    
    McGraw-Edison, 787 F.2d at 1171
    (explaining that third parties’ trademark
    registrations are material to the
    strength of mark "only to the extent that
    the similar marks are promoted by their
    owners or recognized by the consuming
    public"). As to the remaining
    registration, Clean Air introduced no
    evidence that the mark was in use, and
    the registrant’s website confirmed that
    the mark was not being used. Other than
    these cancelled or inactive
    registrations, Clean Air did not
    introduce any evidence of actual use of
    the CAE mark by third parties nor did it
    introduce evidence that the third
    parties’ marks were well-promoted or that
    they were recognized by consumers. See
    
    id. In contrast,
    CAE, Inc. has long used its
    CAE mark in the marketplace. Since the
    1950s, CAE, Inc. has used the CAE mark to
    identify itself and its products and
    services. Today, CAE, Inc. is a
    diversified, multinational company with
    thousands of employees and twenty
    subsidiaries. It has millions of dollars
    in annual sales and expends tens of
    thousands of dollars each year to promote
    its business using the CAE mark, which
    demonstrates that CAE, Inc. has built,
    and continues to build, a reputation for
    the quality of its products and services.
    See Barbecue 
    Marx, 235 F.3d at 1045
    (stating that the length of use of the
    mark and the popularity and reputation of
    the goods demonstrated the strength of
    the mark). Thus, in the absence of
    evidence that third parties actually have
    used the CAE mark or that the CAE mark
    has been promoted and recognized by
    consumers, there is no genuine issue of
    material fact regarding the strength of
    CAE, Inc.’s mark, and the district court
    correctly concluded that the mark is
    strong and distinctive. See McGraw-
    
    Edison, 787 F.2d at 1171
    (finding no
    genuine issue of material fact as to
    strength when the record lacked evidence
    of third parties’ use or consumer
    recognition of a similar trademark).
    6.   Actual Confusion
    Although evidence of actual confusion,
    if available, is entitled to substantial
    weight in the likelihood of confusion
    analysis, see Int’l Kennel 
    Club, 846 F.2d at 1090
    ; 
    McGraw-Edison, 787 F.2d at 1172
    -
    73, this evidence is not required to
    prove that a likelihood of confusion
    exists, see Barbecue 
    Marx, 235 F.3d at 1045
    ; Eli 
    Lilly, 233 F.3d at 465
    . The
    TTAB viewed the absence of a "clear
    instance" of actual confusion during the
    course of the parties’ twenty-year
    coexistence as "indicative" that little
    likelihood of confusion existed. R.34,
    Ex.4 at 12. The district court
    acknowledged the lack of evidence of
    actual confusion; it found that this
    factor weighed "only slightly in favor"
    of a finding that no likelihood of
    confusion existed. R.49 at 25.
    The one instance of actual confusion in
    the record appears in the testimony of
    Frey Frejborg, an employee of CAE, Inc.,
    who stated that one of CAE, Inc.’s
    suppliers had asked him "if there is a
    connection between C.A.E. Clean
    Engineering and CAE ScreenPlates [a CAE,
    Inc. subsidiary]." R.46, Ex.A, Tab 2 at
    5. This testimony, absent the identity of
    the speaker and the time-frame in which
    it was said, is not entitled to great
    weight, particularly because the speaker
    was not a customer of CAE, Inc. but
    rather a supplier. See Smith Fiberglass
    
    Prod., 7 F.3d at 1330-31
    (finding that
    the district court did not err in
    discounting an employee’s testimony about
    an instance of actual confusion that
    lacked the exact quote and identity of
    the speaker).
    One instance of actual confusion has
    been deemed sufficient to weigh in favor
    of finding a likelihood of confusion. See
    Wesley-Jessen Div. of Schering Corp. v.
    Bausch & Lomb, Inc., 
    698 F.2d 862
    , 867
    (7th Cir. 1983). Discounting Mr.
    Frejborg’s testimony, however, does not
    preclude a finding of likelihood of
    confusion. See Sands, Taylor & 
    Wood, 978 F.2d at 960
    ("As we have stated many
    times . . . the plaintiff need not show
    actual confusion in order to establish
    likelihood of confusion." (emphasis in
    original)). Because, as the district
    court noted, instances of actual
    confusion may be difficult to discover,
    the most that the absence of evidence of
    actual confusion can be said to indicate
    is that the record does not contain any
    evidence of actual confusion known to the
    parties. See 3 McCarthy sec. 23:18, at
    23-62. Other than its reliance on a
    twenty-five-year history without reported
    incidents of actual confusion, Clean Air
    has not come forward with hard evidence
    to demonstrate a genuine issue of
    material fact that consumers are not
    likely to be confused by the parties’
    simultaneous use of the CAE mark in
    connection with their businesses. See
    
    McGraw-Edison, 787 F.2d at 1173
    (noting
    that the defendant failed to counter the
    plaintiff’s evidence of actual
    confusion). In light of the paucity of
    evidence either way, the district court
    properly treated this factor as weighing
    only slightly in favor of a conclusion
    that no likelihood of confusion exists.
    7.   Clean Air’s Intent
    The final factor for consideration is
    Clean Air’s intent. The parties do not
    contest the district court’s finding
    that, because Clean Air did not intend to
    palm off its products and services as
    those of CAE, Inc., this factor was
    irrelevant to the likelihood of confusion
    analysis. See Sands, Taylor & 
    Wood, 978 F.2d at 961
    (stating that intent is
    relevant only if the defendant intended
    to palm off its goods as those of the
    plaintiff); Fuji Photo 
    Film, 754 F.2d at 598
    (holding that intent is immaterial
    when the undisputed evidence shows that
    the defendant acted in good faith); 3
    McCarthy sec. 23:107, at 23-248 to 23-251
    (explaining that proof of intent to
    deceive or to confuse is not necessary to
    prove trademark infringement).
    Accordingly, we find no error in the
    district court’s treatment of this
    factor.
    8.   Weighing the Factors
    Although we have recognized that the
    similarity of the marks, evidence of
    actual confusion, and the defendant’s
    intent are the three "most important"
    factors in the likelihood of confusion
    analysis, Eli 
    Lilly, 233 F.3d at 462
    ,
    there is "no hard and fast requirement"
    that all three of these factors must
    weigh in the plaintiff’s favor in order
    to find that a likelihood of confusion
    exists, Ty, 
    Inc., 237 F.3d at 902
    .
    Rather, the district court must give
    appropriate weight to the factors that
    are particularly important based on the
    facts of each case. See Ty, 
    Inc., 237 F.3d at 901
    -02 (holding that the
    magistrate judge did not err in placing
    greater weight on the similarity of
    marks, the similarity of products, and
    the area and manner of concurrent use);
    Barbecue 
    Marx, 235 F.3d at 1046
    (stating
    that the key factors in the likelihood of
    confusion analysis in that case were the
    defendant’s intent, actual confusion, and
    the degree of care exercised by
    customers).
    Presented with the administrative record
    as well as a substantial amount of new
    evidence, the district court placed
    greater weight on the identical
    appearance of the CAE marks, the
    similarity of the products and services
    bearing the CAE mark, the identical
    manner and channels of commerce in which
    the parties used the CAE mark, the
    strength of the CAE mark registered by
    CAE, Inc., and, to a lesser extent, the
    degree of care likely to be exercised by
    consumers. The court based its findings
    on a record of undisputed facts and
    analyzed the importance of each factor in
    the context of this particular case and
    with appropriate deference to the
    findings of the TTAB. Clean Air failed to
    demonstrate a genuine issue of material
    fact as to any of the factors; therefore,
    the district court correctly concluded
    that a likelihood of confusion existed as
    a matter of law. We conclude that the
    district court correctly balanced all
    seven factors. Accordingly, the district
    court correctly entered summary judgment
    in favor of CAE, Inc. and against Clean
    Air based on a finding that consumers
    were likely to be confused by the
    parties’ contemporaneous use of the CAE
    mark in connection with their goods and
    services. See Door 
    Sys., 83 F.3d at 173
    (affirming summary judgment when there
    was no genuine issue of material fact as
    to likelihood of confusion).
    Conclusion
    The district court’s conclusion that
    consumers are likely to be confused by
    the parties’ simultaneous use of the CAE
    mark was correct and is conclusive as to
    all claims. Accordingly, we affirm the
    judgment of the district court in all
    respects.

    District Judge for the District of Nebraska,
    sitting by designation.
    /2 This trademark was cancelled on May 28, 2001, and
    is no longer active.
    /3 CAE, Inc. also has featured the CAE mark in the
    names of most of its former subsidiaries and
    divisions: CAE International, Ltd.; CAE Fibre-

    and CAE Aviation, Ltd.
    /4 CAE Machinery, Ltd., another CAE, Inc. subsidiary
    that designs, manufactures, and sells equipment
    to the pulp and paper industry and offers repair
    and servicing of that equipment under the CAE
    name, also advertises in publications for the
    pulp and paper industry, including TAPPI Journal.
    /5 In the TTAB proceeding, CAE, Inc. produced the
    following evidence: Answers to Interrogatories;
    Response to First Request for Admissions; Re-

    L. Adams; Testimony of Frey Frejborg; Testimony
    of Robert Kemerer; Testimony of Alexander T.
    Wilson; Testimony of James W. Best; Testimony of
    James S. Herz; Testimony of Robert Aimonetti; and
    CAE, Inc.’s Notice of Reliance, which contained
    published advertisements of CAE, Inc. and Clean
    Air.
    Clean Air produced the following evidence in
    this proceeding: Answers to Interrogatories;
    Responses to Request to Admit; Responses to CAE,
    Inc.’s Discovery Requests; Deposition of Frank S.
    Kilvinger; Deposition of William I. Walker;
    Testimony of Frank S. Kilvinger; Testimony of

    articles from Pollution Engineering, Chicago
    Daily Law Bulletin and the Wall Street Journal;
    CAE, Inc.’s trademark renewal file materials; and
    results of "CAE" trademark name searches and
    registrations.
    Although the record is not entirely clear, it
    appears that all of this evidence also was pre-
    sented to the district court, with the exception
    of CAE, Inc.’s trademark renewal file materials
    and the articles from Pollution Engineering,
    Chicago Daily Law Bulletin and the Wall Street
    Journal.

    /7 After CAE, Inc. advised the court that it would
    not pursue its dilution claims in light of the
    decision in Nike, Inc. v. Nike Securities L.P.,
    50 U.S.P.Q.2d 1202 (N.D. Ill. Feb. 18, 1999), the
    district court entered judgment in favor of Clean
    Air on Counts III and IV. This ruling is not at
    issue on appeal.
    /8 We denied Clean Air’s motion for a stay pending
    appeal.
    /9 Although Zurko involved the Federal Circuit’s
    review of a decision of the PTO, the Court’s
    holding also has been applied to findings of fact
    made by the TTAB. See, e.g., On-Line 
    Careline, 229 F.3d at 1085
    . Furthermore, whether the ag-
    grieved party elects direct review by the Federal
    Circuit or initiates a new action in the district
    court, both courts should apply the APA standard
    of review to the TTAB’s factfinding. See 
    Zurko, 527 U.S. at 164
    (rejecting the argument that the
    "two paths" for review would create "an anomaly"
    in the standard of review).
    /10 The Supreme Court recognized that the difference
    between the clearly erroneous standard and the
    substantial evidence standard "is a subtle one--
    so fine that (apart from the present case) we
    have failed to uncover a single instance in which
    a reviewing court conceded that use of one stan-
    dard rather than the other would in fact have
    produced a different outcome." 
    Zurko, 527 U.S. at 162
    -63; see also 3 McCarthy sec. 21:22.1, at 21-
    32 ("It is hard to see more than a subtle differ-
    ence between the old and new standards of appel-
    late review of facts.").
    /11 The first element of a Lanham Act claim, whether
    CAE, Inc.’s marks are protectable, is not at
    issue here. As the district court noted, it is
    undisputed that CAE, Inc. registered the block
    letters "CAE" and that Clean Air advertised
    products and services using the block letters
    "CAE" without permission from CAE, Inc. R.49 at
    15. Therefore, the only issue is whether Clean
    Air’s use of the CAE mark is likely to cause
    confusion. See Eli 
    Lilly, 233 F.3d at 461
