    MoneyGram Payment Systems, Inc. (“MoneyGram”)
    appeals from the final judgment of the United States
    District Court for the Western District of Texas in favor of
    the Western Union Company (“Western Union”). A jury
    found infringement of certain claims of U.S. Patents
    6,488,203 (the “’203 patent”); 6,502,747 (the “’747 pat-
    ent”); 6,761,309 (the “’309 patent”); and 7,070,094 (the
    “’094 patent”), and found those patents not invalid for
    obviousness. The district court denied MoneyGram’s
    renewed motion for judgment as a matter of law (“JMOL”)
    on infringement and invalidity of the asserted patents.
    Western Union Co. v. MoneyGram Int’l, Inc., No. 1:07-cv-
    00372, Dkt. No. 429 (W.D. Tex. Nov. 17, 2009) (“JMOL
    Opinion”). Because we find that the asserted claims in
    the patents in suit would have been obvious to a person of
    ordinary skill in the art at the time of filing, we reverse.
    BACKGROUND
    Western Union owns the ’203, ’747, ’309, and ’094
    patents directed to a system for performing money trans-
    fers. The ’203, ’747, and ’309 patents (collectively, the
    “send patents”) specifically relate to methods of sending
    money through a financial services institution (“FSI”).
    The ’094 patent claims methods for receiving transferred
    money. The patented system relates to money transfer
    services such as those offered by Western Union through
    retail locations where a customer may identify a recipient
    and tender an amount to be delivered to the recipient.
    3                            WESTERN UNION   v. MONEYGRAM
    The money transfer service collects the amount from the
    retail location and completes the transaction for the
    customer. Some of the traditional money transfer sys-
    tems required money senders to fill out forms with trans-
    action information such as recipient information and the
    amount of money to be transferred. The ’203 patent
    claims a method of performing a formless money transfer
    using an electronic transaction fulfillment device
    (“ETFD”).     Figure 1 from the ’203 patent depicts an
    embodiment of the patented system.
    Figure 1 of the ’203 patent
    In the patented system, a customer has telephone ac-
    cess to the customer service representative (“CSR”) at the
    WESTERN UNION   v. MONEYGRAM                            4
    financial institution, who obtains details of the transfer
    and “stages” the money transfer for the customer, storing
    the transaction details on a host computer (18). The
    customer is later able to complete the transaction at a
    retail location where an agent is able to retrieve the
    transaction from the computer (18) through an ETFD (22)
    and accept the required amount of money from the cus-
    tomer. Claim 1 is representative of the patented inven-
    tion:
    1. A method of performing a money transfer send
    transaction, the method comprising:
    providing a sender direct access to an em-
    ployee of a financial services institution in
    order to receive transaction details from
    the sender;
    storing, on a data base, the transaction
    details provided by the sender, wherein
    the transaction details include a desired
    amount of money to be sent by the sender
    to a recipient;
    establishing a code that corresponds to the
    transaction details stored on the data
    base, wherein the code is established for
    use by the sender during the send transac-
    tion;
    storing the code on the data base such that
    the code is useable to identify the send
    transaction on the data base;
    5                             WESTERN UNION   v. MONEYGRAM
    entering the code into an electronic trans-
    action fulfillment device in communication
    with the data base to retrieve the transac-
    tion details from the data base after the
    step of storing the code on the data base;
    and
    determining a collect amount, to be col-
    lected from the sender, based on the
    transaction details;
    wherein the code is not provided by or to
    the recipient for use by the recipient dur-
    ing the send transaction.
    ’203 patent, claim 1 (emphases added).
    Claim 12 is dependent on claim 1 and adds the limita-
    tion that an employee of the money transfer business
    provides the transaction identifying code. Claim 16,
    which is also dependent on claim 1, adds the limitation of
    collecting the money from the sender, notifying the data-
    base of the collection, and recording the transaction as
    complete. The ’203 patent was filed on October 26, 1999
    and issued on December 3, 2002. The ’747 patent, also
    filed in 1999, and the ’309 patent, filed in 2004, are both
    continuations of the ’203 patent. The ’309 patent claims
    are similar and substantially identical in scope to the ’203
    patent claims. The ’747 patent primarily adds the use of
    internet-based communications, using an internet com-
    munications protocol (“the TCP/IP protocol”), to the
    money transfer system and claims the use of a “first
    computer” instead of “the data base” used in the ’203
    patent. Claim 20 is illustrative:
    WESTERN UNION   v. MONEYGRAM                           6
    20. A method of performing a money transfer send
    transaction through a financial services institu-
    tion, the method comprising:
    receiving transaction details on a first
    computer of the financial services institu-
    tion, wherein the transaction details are
    provided by a sender and include a desired
    amount of money to be sent by the sender
    to a recipient;
    storing the transaction details on the first
    computer;
    establishing a code that corresponds to the
    transaction details, wherein the code is es-
    tablished for use by the sender during the
    send transaction;
    storing the code on the first computer such
    that the code is useable to identify the
    send transaction;
    receiving the code at the first computer
    from an electronic transaction fulfillment
    device in communication with the first
    computer after the step of storing the code
    on the first computer;
    validating the code received from the
    transaction fulfillment device by compar-
    ing the code received from the transaction
    7                            WESTERN UNION   v. MONEYGRAM
    fulfillment device with the code stored on
    the first computer; and
    transmitting a collect amount, to be col-
    lected from the sender, from the first com-
    puter to the transaction fulfillment device
    if the code received from the transaction
    fulfillment device is valid;
    wherein at least a portion of the method is
    performed using TCP/IP, and wherein the
    code is not provided by or to the recipient
    for use by the recipient during the send
    transaction.
    ’747 patent, claim 20 (emphases added). During prosecu-
    tion of the ’747 and ’309 patents, the inventors filed a
    terminal disclaimer limiting the terms of those patents to
    that of the ’203 patent in response to double patenting
    rejections by the USPTO.
    Like the patented invention, a prior art system owned
    by Orlandi Valuta, another money transfer service com-
    pany, also employed technology that did not require
    customers to fill out forms to transfer money. Below is a
    figure from Orlandi Valuta’s literature on its “Red Phone”
    system:
    WESTERN UNION   v. MONEYGRAM                             8
    Orlandi Valuta’s Red Phone technology, used as early
    as 1997, required a customer to use a telephone to initiate
    a transaction with an Orlandi Valuta CSR. The telephone
    typically used by the customer was a red colored tele-
    phone available at the retail location that automatically
    connected to an Orlandi Valuta CSR in Los Angeles,
    California. The CSR would enter information received
    from the customer into the Orlandi Valuta computer
    system, whereupon the system would fax an invoice to the
    retail location of the customer or to the one that the
    customer had requested. The Orlandi Valuta customer
    would not receive a confirmation number for the transac-
    tion, but was simply required to wait at the retail loca-
    9                            WESTERN UNION   v. MONEYGRAM
    tion. Upon receipt of the fax, an agent at the retail loca-
    tion would call out the name of the customer, who could
    then tender the required amount to that agent. Western
    Union acquired Orlandi Valuta in 1997, shortly after it
    had developed the formless transfer system.
    The patents in suit claim to solve shortcomings of the
    Orlandi Valuta system. The inventors, Earney Souten-
    burg and Dean Seifert, both employees of Western Union,
    were also responsible for Orlandi Valuta’s technology
    group following Western Union’s acquisition of that
    company. Prior to developing the patented system, later
    commercialized as Western Union’s “Yellow Phone”
    system, the inventors evaluated Orlandi Valuta’s formless
    money transfer system to determine if Western Union
    could utilize it on a larger scale to support its higher
    volumes of money transfers. The inventors claim that the
    Orlandi Valuta system was not a viable formless option
    for Western Union.
    MoneyGram, also a money transfer service company
    and a direct competitor of Western Union, developed and
    deployed its “FormFree” money transfer system in 2000.
    Like the patented system, the MoneyGram system pro-
    vided the customer with a confirmation number, which
    when provided by the customer to a retail agent allowed
    for completion of the previously staged transaction. This
    confirmation number was also stored in a Confirmation
    File database along with other information, such as the
    transfer amount, of the staged transaction. In September
    2003, when MoneyGram learned of the patents in suit, it
    developed a work-around to avoid infringement of those
    patent claims. The redesigned system no longer stored
    the desired amount to be sent in the Confirmation File
    database for pending transactions. Instead, the customer
    was required to provide that information again to the
    agent at the retail location where the customer funded
    WESTERN UNION   v. MONEYGRAM                            10
    and completed the transaction. MoneyGram obtained a
    formal noninfringement opinion from outside counsel on
    its redesigned system with regard to Western Union’s
    patents.
    In May 2007, Western Union filed this lawsuit in the
    United States District Court for the Western District of
    Texas, ultimately asserting infringement of claims 1, 12,
    16, and 21 of the ’203 patent; claim 20 of the ’747 patent;
    claims 12 and 22 of the ’309 patent; and claim 2 of the
    ’094 patent. In December 2008, the district court con-
    strued claims of all four patents at issue. Western Union
    Co. v. MoneyGram Int’l, Inc., No. 1:07-cv-00372, 
    2008 WL 5731946
     (W.D. Tex. Nov. 6, 2008). In August 2009, the
    district court granted summary judgment that Money-
    Gram’s design-around system did not infringe the as-
    serted claim of the ’094 patent. Western Union Co. v.
    MoneyGram Int’l., Inc., No. 1:07-cv-00372, Dkt. No. 353
    (W.D. Tex. Aug. 21, 2009).
    The case was tried to a jury in September 2009. Dur-
    ing trial, Western Union withdrew its claim of infringe-
    ment of the ’309 patent and claim 21 of the ’203 patent as
    to MoneyGram’s redesigned system. Following trial, the
    jury found that MoneyGram’s redesigned system in-
    fringed claims 1, 12, and 16 of the ’203 patent and claim
    20 of the ’747 patent under the doctrine of equivalents. It
    found that MoneyGram’s pre-design-around system,
    however, literally infringed the same claims as well as
    other claims that Western Union had asserted only
    against the earlier MoneyGram system: claim 21 of the
    ’203 patent and claims 12 and 22 of the ’309 patent. On
    claim 2 of the ’094 patent, also asserted only against the
    earlier system, the jury found infringement under the
    doctrine of equivalents. The jury rejected MoneyGram’s
    argument that the asserted patent claims were obvious in
    light of the Orlandi Valuta prior art system. The jury
    11                            WESTERN UNION   v. MONEYGRAM
    awarded Western Union reasonable royalty damages in
    the amount of $16,529,501.81.
    Following trial, MoneyGram renewed its JMOL mo-
    tion on obviousness of the asserted patent claims based on
    the Orlandi Valuta system, and on noninfringement of the
    asserted patent claims. Western Union renewed its JMOL
    motion on literal infringement of the ’747 patent. The
    court denied all JMOL motions. In deciding Money-
    Gram’s JMOL motion on obviousness, the court found
    that MoneyGram had waived its argument on the issue.
    JMOL Op., slip op. at 31. Nevertheless, the court pro-
    ceeded to evaluate MoneyGram’s motion on its merits and
    decided that the jury had a legally sufficient evidentiary
    basis upon which it could conclude that the asserted
    claims were not obvious. Id. at 32. Specifically, regarding
    the Orlandi Valuta prior art system, the court found that
    it did not employ an ETFD terminal at the retail location
    and did not use a code. Id. at 31-32. The court concluded
    that it would not have been obvious for a person of ordi-
    nary skill in the art to combine these two elements with
    the existing Orlandi Valuta system. Id. Moreover, it held
    that secondary considerations such as commercial success
    and investments made by both parties in designing sys-
    tems better than the Orlandi Valuta system weighed
    against a finding of obviousness. Id. Thus, the district
    court denied MoneyGram’s JMOL motion. Lastly, the
    court granted a permanent injunction against Money-
    Gram. Id. at 60. MoneyGram now appeals the court’s
    rulings on claim construction, infringement, and invalid-
    ity of the ’203, ’747, and ’309 patents. 1 We have jurisdic-
    tion pursuant to 
    28 U.S.C. § 1295
    (a)(1).
    1  Western Union cross-appealed the court’s denial
    of its JMOL motion on literal infringement of the ’747
    patent, which we dismissed as an improper cross-appeal.

    DISCUSSION
    Obviousness
    We begin with the district court’s denial of Money-
    Gram’s JMOL motion on obviousness. We review the
    denial of a JMOL motion de novo, applying law from the
    regional circuit, in this case, the Fifth Circuit. Harris
    Corp. v. Ericsson lnc., 
    417 F.3d 1241
    , 1248 (Fed. Cir.
    2005). Under Fifth Circuit law, a motion for judgment as
    a matter of law “should be granted by the trial court if,
    after considering all the evidence in the light [favorable
    to] and with all reasonable inferences most favorable to
    the party opposed to the motion, the facts and inferences
    point so strongly and overwhelmingly in favor of one
    party that the court concludes that reasonable jurors
    could not arrive at a contrary verdict.” Bellows v. Amoco
    Oil Co., 
    118 F.3d 268
    , 273 (5th Cir. 1997).
    At the outset, Western Union argues that Money-
    Gram has waived its right to appeal several issues includ-
    ing obviousness of the asserted patent claims based on the
    Orlandi Valuta system in combination with a keypad. It
    argues that the district court properly found this argu-
    ment waived below because MoneyGram failed to specifi-
    cally raise obviousness based on a keypad device in its
    Rule 50(a) motion and that omission ran afoul of the
    purpose of Rule 50. Therefore, Western Union contends,
    MoneyGram cannot attempt to incorporate new prior art
    arguments on appeal.
    We disagree and decide that the district court erred in
    concluding that MoneyGram had waived its obviousness
    argument specifically as it related to Orlandi Valuta.
    Rule 50(a) requires that a motion for judgment as a
    Western Union Co. v. MoneyGram Payment Sys., Inc., No.
    2010-1080, Dkt. No. 54 (Fed. Cir. May 3, 2010).
    13                            WESTERN UNION   v. MONEYGRAM
    matter of law “must specify the judgment sought and the
    law and facts that entitle the movant to the judgment.”
    Fed. R. Civ. P. 50(a)(2). We have held that even a cursory
    motion suffices to preserve an issue on JMOL so long as it
    “serves the purposes of Rule 50(a), i.e., to alert the court
    to the party’s legal position and to put the opposing party
    on notice of the moving party’s position as to the insuffi-
    ciency of the evidence.” Blackboard, Inc. v. Desire2Learn,
    Inc., 
    574 F.3d 1371
    , 1379–80 (Fed. Cir. 2009). Fifth
    Circuit law, applicable here, also construes the rule
    liberally, excusing “technical noncompliance” when the
    purposes of the rule are satisfied. Navigant Consulting,
    Inc. v. Wilkinson, 
    508 F.3d 277
    , 288-89 (5th Cir. 2007)
    (citation omitted). Applying that liberal standard, we find
    no waiver here. MoneyGram argued in its Rule 50(a)
    motion that it was entitled to JMOL on obviousness on all
    asserted claims of all asserted patents, specifically listing
    Orlandi Valuta as prior art that rendered the claims
    obvious. We agree with MoneyGram that those state-
    ments were sufficient to preserve MoneyGram’s obvious-
    ness arguments as to Orlandi Valuta.
    On the merits, MoneyGram argues that the claimed
    invention simply takes a known prior art system and adds
    obvious elements, such as the use of an off-the-shelf
    keypad to access transaction information. It contends
    that the patent specification itself concedes the fact that
    the core concept of the claimed invention, namely, the
    idea of providing a customer with direct access to a CSR
    who can store the customer’s transaction details in the
    FSI’s database, was well-known in the prior art. Accord-
    ing to MoneyGram, the patented invention simply re-
    placed the fax machine in the Orlandi Valuta system with
    an off-the-shelf keypad—a well-known device in the art.
    MoneyGram further argues that the district court incor-
    rectly concluded that the Orlandi Valuta system did not
    WESTERN UNION   v. MONEYGRAM                             14
    use a code even though there was ample evidence that
    such a code existed in that system by the name “clave,”
    and users could use the clave to obtain information about
    their money transfers.        Regardless whether Orlandi
    Valuta taught that limitation, MoneyGram argues, add-
    ing a numerical code to a system that processes financial
    transactions would have simply been common sense to a
    person of skill in the art. As for the ’747 patent, which
    primarily added the use of internet-based communica-
    tions to the ’203 patent, MoneyGram argues that such an
    improvement would have been obvious under this court’s
    precedent. On secondary considerations relied upon by
    the district court, MoneyGram contends that they have no
    relation to the claimed invention. Thus, MoneyGram
    contends that it established, by clear and convincing
    evidence at trial, that the asserted claims were obvious.
    It further notes that in response to its case on obvious-
    ness, Western Union did not even offer a rebuttal before
    the jury. Therefore, MoneyGram argues, there is no
    evidence on the record to support the jury’s underlying
    fact findings or its ultimate conclusion of nonobviousness.
    Western Union argues in response that the Orlandi
    Valuta system may share some similarities with the
    patented invention, but it does not teach the core concepts
    claimed by its patents. Western Union argues that the
    Orlandi Valuta system lacks at least three critical ele-
    ments: (1) the “code” that is established for use by the
    sender during the send transaction; (2) an ETFD; and (3)
    the use of the Internet. Regarding the code, Western
    Union argues, the jury heard testimony that the clave in
    the Orlandi Valuta system was not given to the customer
    until after the transaction had been completed, and that
    was sufficient evidence for the jury to find that limitation
    missing from the prior art. Likewise, it argues, the ETFD
    claimed is one used for completing the money transfer
    15                            WESTERN UNION   v. MONEYGRAM
    transaction, and no evidence presented at trial estab-
    lished that the fax machine in the Orlandi Valuta system
    could provide similar transaction fulfillment functionality.
    According to Western Union, the keypads known in the
    prior art were not the same as an ETFD, and MoneyGram
    presented no evidence that such a keypad could be used to
    retrieve transaction details from a database, as claimed in
    the patents. Western Union further argues that to the
    extent these elements were well-known in the prior art,
    the jury’s verdict of nonobviousness is easily supported by
    the lack of evidence of any motivation for one skilled in
    the art to have combined these elements with the Orlandi
    Valuta system. It contends, for example, that its own
    witness testified that extensive coding work was required
    to incorporate an ETFD into the commercial embodiment
    of the asserted patents. Lastly, Western Union argues,
    evidence of secondary considerations, such as the com-
    mercial success of its Yellow Phone system, cannot be
    ignored in evaluating the jury’s finding of nonobviousness.
    We agree with MoneyGram that in light of the Or-
    landi Valuta system, Western Union’s asserted claims
    would have been obvious as a matter of law. Obviousness
    is a question of law based on underlying findings of fact.
    In re Kubin, 
    561 F.3d 1351
    , 1355 (Fed. Cir. 2009). We
    review the jury’s determination of underlying fact for
    substantial evidence, but we review the ultimate conclu-
    sion of obviousness de novo. Boston Sci. Scimed, lnc. v.
    Cordis Corp., 
    554 F.3d 982
    , 990 (Fed. Cir. 2009); Muni-
    auction, Inc. v. Thomson Corp., 
    532 F.3d 1318
    , 1324 (Fed.
    Cir. 2008). The underlying factual inquiries include (1)
    the scope and content of the prior art; (2) the differences
    between the prior art and the claims at issue; (3) the level
    of ordinary skill in the art; and (4) any relevant secondary
    considerations, such as commercial success, long felt but
    unsolved needs, and the failure of others. Graham v.
    WESTERN UNION   v. MONEYGRAM                              16
    John Deere Co., 
    383 U.S. 1
    , 17-18 (1966). Here the level
    of skill of one of ordinary skill in the art and the scope of
    the claims of the patents in suit are not at issue. The
    parties’ disputes revolve around whether the prior art
    taught three specific elements of the claimed inventions,
    whether there was a motivation to combine these ele-
    ments with the prior art system, and whether secondary
    considerations support a finding of nonobviousness. We
    address each in turn.
    A. Combining an ETFD and the Use of the Internet
    with the Orlandi Valuta System
    Western Union argues that the claimed ETFD is more
    than a simple keypad and includes functionality that
    cannot be achieved by simply exchanging the fax machine
    in the Orlandi Valuta system for a keypad. It argues that
    a keypad cannot communicate with a database to retrieve
    the transaction details. It also argues that there is no
    evidence in the record that a keypad equivalent to the
    ETFD was “well-known” in the prior art. Moreover, it
    argues, the combination would not have been obvious to a
    person of ordinary skill in the art.
    We find each of these arguments unpersuasive. The
    patent specification itself describes the addition of “an
    electronic transaction fulfillment device, such as an
    electronic terminal having a keypad,” ’203 patent col.4
    ll.8-10, and states that one embodiment is an FDX-400,
    available from Western Union, 
    id.
     col.4 ll.21-23. It ex-
    plains that FDX-400 comprises a numeric keypad, one or
    more function keys, and a display device. 
    Id.
     col.4 ll.23-
    25. MoneyGram presented that evidence at trial. It
    presented evidence to show that the Orlandi Valuta
    system used an FDX-400 device, although at the CSR
    location, not at the retail location. It also presented
    testimony that various electronic keypad devices, such as
    17                            WESTERN UNION   v. MONEYGRAM
    those used for credit card transaction processing, already
    existed at retail locations. We conclude that no reason-
    able jury should have found that MoneyGram failed to
    present sufficient evidence to demonstrate that electronic
    transaction devices, at least as sophisticated as the FDX-
    400, were commonplace in the art at the time of the
    invention.
    We next address the question whether there was mo-
    tivation to combine the prior art ETFD with the Orlandi
    Valuta system. An obviousness determination is not the
    result of a rigid formula disassociated from the considera-
    tion of the facts of a case. Indeed, the common sense of
    those skilled in the art demonstrates why some combina-
    tions would have been obvious where others would not.
    See KSR Int’l Co. v. Teleflex Inc., 
    550 U.S. 398
    , 416 (2007)
    (“The combination of familiar elements according to
    known methods is likely to be obvious when it does no
    more than yield predictable results.”). Based on the
    Supreme Court’s reasoning in KSR, we have subsequently
    held that applying computer and internet technology to
    replace older electronics has been commonplace in recent
    years. See Muniauction Inc., 
    532 F.3d at 1327
    ; Leapfrog
    Enters., Inc. v. Fisher-Price, Inc., 
    485 F.3d 1157
    , 1161
    (Fed. Cir. 2007).         In Leapfrog, we held that
    “[a]ccommodating a prior art mechanical device that
    accomplishes [the goal of teaching a child to read phoneti-
    cally] to modern electronics would have been reasonably
    obvious to one of ordinary skill in designing children’s
    learning devices.” 
    485 F.3d at 1161
    . Our conclusion of
    obviousness was based in part on the reasoning that
    “[a]pplying modern electronics to older mechanical devices
    has been commonplace in recent years.” 
    Id.
     Similarly, in
    Muniauction, we concluded that conducting previously
    known methods of bidding through an Internet web
    browser was obvious because it amounted to no more than
    WESTERN UNION   v. MONEYGRAM                            18
    applying the use of the Internet to existing electronic
    processes at a time when doing so was commonplace. 
    532 F.3d at 1327
    . We rejected the patentee’s arguments that
    even where it was routinely done, such incorporation
    would have been beyond the ability of a person of ordinary
    skill in the art. 
    Id.
    Here too, we find the use of an electronic transaction
    device where the prior art employed a fax machine to be
    an unpatentable improvement at a time when such a
    transition was commonplace in the art. See In re Mettke,
    
    570 F.3d 1356
    , 1360–61 (Fed. Cir. 2009) (finding it obvi-
    ous to add Internet access to a prior art kiosk that in-
    cluded a fax-machine). We fail to see how it would have
    been difficult for a person of ordinary skill in the art to
    integrate an electronic transaction device that was avail-
    able from Western Union itself into a well-known money
    transfer system that was also owned by Western Union at
    the time of the invention. Specific limitations that West-
    ern Union points to, such as using the ETFD to retrieve
    information from a database, are simply routine modifica-
    tions that are a part of adapting a new technology to an
    existing system. Here, a person of ordinary skill in the
    art replacing a fax machine with an ETFD that could
    access a database would necessarily have known how to
    retrieve transaction details from the database.
    Western Union further argues that it spent signifi-
    cant resources in developing its commercial embodiment
    of the patented invention and that the integration of the
    ETFD into a formless system was not a simple one that a
    skilled person could accomplish without any experimenta-
    tion. Although we have held that a finding of obviousness
    may not be proper where the prior art merely provided a
    promising field for experimentation, In re Kubin, 
    561 F.3d at 1359-60
    , the testimony that Western Union relies upon
    here relates only to the effort that its engineers invested
    19                             WESTERN UNION   v. MONEYGRAM
    in software implementation of its commercial system, not
    toward any inventive aspect claimed in the patents.
    Thus, we conclude that the combination of the ETFD with
    the Orlandi Valuta system would have been obvious to a
    person of ordinary skill in the art at the time of the inven-
    tion.
    For the same reasons, we are not persuaded by West-
    ern Union’s arguments that the improvements recited in
    claim 20 of the ’747 patent render the subject matter of
    the claim nonobvious. The claim primarily adds the use
    of internet-based communications, specifically the TCP/IP
    protocol to the invention patented in the ’203 patent. We
    conclude that it would have been obvious for a person of
    ordinary skill in the art to use internet-based protocols in
    networking the systems used in the ’203 patent. See
    Papyrus Tech. Corp. v. N.Y. Stock Exch., LLC, 
    653 F. Supp. 2d 402
    , 432 (S.D.N.Y. 2009) (finding that adding “a
    connectionless protocol (TCP/IP) that has been used in
    electronic communications, such as the Internet, since the
    1980s” to other obvious elements of claim “adds nothing
    new to the field of endeavor”), affirmed, Case No. 2010-
    1166, 
    2010 WL 3934367
     (Fed. Cir. Oct. 7, 2010).
    B. Use of a Code
    Western Union argues, and the district court found,
    that the fact that the Orlandi Valuta system did not
    provide a code to the customer meant that that system did
    not disclose the use of a code for that specific functionality
    to a person of ordinary skill in the art. MoneyGram
    responds that the Orlandi Valuta system did in fact use a
    clave to identify transactions. Moreover, it contends, the
    basic idea of identifying transactions by codes is well-
    known to anyone who has ever purchased or reserved an
    item and received a confirmation number from a repre-
    sentative.
    WESTERN UNION   v. MONEYGRAM                             20
    We agree with MoneyGram that the Orlandi Valuta
    system taught the use of a code that corresponds to a
    transaction in the system. At trial, MoneyGram estab-
    lished that the code printed on the invoice given to the
    Orlandi Valuta customer could be used to track the trans-
    action. In light of this evidence, we conclude that it would
    have been common sense for a person of ordinary skill in
    the art to use a code generated at the staging phase and
    provided to the customer to be used at the retail location
    to look up transaction information in the manner claimed
    by the asserted patents. See Perfect Web Techs., Inc. v.
    InfoUSA, Inc., 
    587 F.3d 1324
    , 1329 (Fed. Cir. 2010) (In
    KSR, “the Supreme Court instructed that factfinders may
    use common sense in addition to record evidence.”). In
    Perfect Web, the patented technology involved a method of
    managing bulk e-mail that required repeating a series of
    steps until the desired quantity of e-mail had been sent.
    In affirming the district court’s holding of obviousness, we
    reasoned that where there was a failure to reach the
    targeted number, common sense dictated that one should
    try again. Id. at 1330.
    It is undisputed here that when a CSR entered a
    transaction into the Orlandi Valuta system, it generated a
    corresponding code and that that code was also printed on
    the invoice that the customer received at the retail loca-
    tion. Because, in that system, the transaction details
    were faxed to the retail location, the customer’s name was
    used to validate and complete the transaction. Where the
    fax machine is replaced with an electronic transaction
    device that is capable of retrieving information from the
    host computer, it would be common sense for a person of
    skill to use the transaction code throughout the life of the
    transaction, including “use by the recipient during the
    send transaction.” See KSR, 
    550 U.S. at 421
     (“A person of
    ordinary skill is also a person of ordinary creativity.”).
    21                            WESTERN UNION   v. MONEYGRAM
    Consequently, other code-related limitations in the as-
    serted claims, such as entering the code into the ETFD
    and validation of the code by the host computer, would
    have also been a matter of common sense to a person of
    ordinary skill in the art.
    Western Union argues that MoneyGram did not sepa-
    rately prove that additional limitations of each of the
    asserted dependent claims were present in the prior art
    rendering each of those claim obvious as well. Western
    Union argues, for example, that dependent claim 12 of the
    ’203 patent adds the limitation that an employee of the
    money transfer business provides the transaction identi-
    fying code to the customer.       Western Union, however,
    does not explain why such an insignificant detail would
    not have been obvious to a person of skill in the art. We
    similarly decide that each of the other asserted claims of
    the ’203 and ’309 patents adds only trivial improvements
    that would have been a matter of common sense to one of
    ordinary skill in the art, and that no reasonable jury could
    find any of those claims to have been nonobvious. We
    therefore conclude, after considering all the evidence
    presented at trial in the light most favorable to Western
    Union, that each of the disputed elements of the asserted
    claims was present in the prior art, that the claimed
    combination represents no more than “the predictable use
    of prior art elements according to their established func-
    tions,” KSR, 
    550 U.S. at 417
    , and as such, the claims
    would have been obvious as a matter of law.
    C. Secondary Considerations
    MoneyGram argues that the district court’s analysis
    of secondary considerations suffered from a fundamental
    flaw in that it failed to identify the nexus between the
    claimed inventions and the secondary considerations
    identified by Western Union. In relying on commercial
    WESTERN UNION   v. MONEYGRAM                             22
    success, MoneyGram points out, the district court failed to
    explain how the fact that Western Union had been trans-
    ferring billions of dollars was in any way related to the
    patented invention. It contends that the district court
    failed to consider Western Union’s brand name recogni-
    tion and marketing, or even the size of Western Union’s
    business prior to adopting the patented system, when it
    used systems such as Orlandi Valuta. It further argues
    that in relying on the amounts that the parties had spent
    on developing formless systems, the district court failed to
    analyze whether those investments directly related to
    conceiving the claimed inventions, such as an ETFD.
    According to MoneyGram, absent those improper assump-
    tions, there is no legally relevant evidence of secondary
    considerations to support the nonobviousness of the
    inventions of the asserted claims.
    Western Union argues that to the extent the district
    court’s finding of nonobviousness was based on secondary
    considerations, it was well-supported in the record. It
    contends that it presented evidence to the jury that the
    Yellow Phone was commercially successful, transferring
    billions of dollars and generating millions of dollars in
    revenue each year. Throughout its arguments on nonob-
    viousness, Western Union places significant emphasis on
    the fact that both parties evaluated the Orlandi Valuta
    system that existed at the time of the invention and
    decided to develop their own new and improved systems.
    We agree with MoneyGram that the district court
    erred in its analysis of secondary considerations of obvi-
    ousness and in its heavy reliance on them in denying
    MoenyGram’s JMOL of obviousness. We find the evi-
    dence of secondary considerations irrelevant in supporting
    the jury verdict of nonobviousness. Our case law clearly
    requires that the patentee must establish a nexus be-
    tween the evidence of commercial success and the pat-
    23                            WESTERN UNION   v. MONEYGRAM
    ented invention. See In re Huang, 
    100 F.3d 135
    , 140 (Fed.
    Cir. 1996) (holding that the proponent must offer proof
    “that the sales were a direct result of the unique charac-
    teristics of the claimed invention”) (emphasis added); In re
    GPAC Inc., 
    57 F.3d 1573
    , 1580 (Fed. Cir. 1995) (“For
    objective [evidence of secondary considerations] to be
    accorded substantial weight, its proponent must establish
    a nexus between the evidence and the merits of the
    claimed invention.”) (emphasis added).
    Here, Western Union failed to present any relevant
    evidence proving a nexus between its commercial success
    and its claimed invention. The only evidence that West-
    ern Union points us to is testimony from one of its em-
    ployees explaining how the “Money Transfer by Phone” or
    Yellow Phone system that allowed customers simply to
    pick up the phone and have a Western Union CSR stage a
    transaction for them enabled dramatic growth of Western
    Union’s business. However, Western Union does not
    claim that it invented a formless money transfer system
    or that systems such as Orlandi Valuta are not prior art
    to the claimed invention. It cannot therefore claim any
    commercial success that arose from features of the system
    found in the prior art as a consideration for nonobvious-
    ness of its claimed invention. Ormco Corp. v. Align Tech.,
    Inc., 
    463 F.3d 1299
    , 1312 (Fed. Cir. 2006) (“[I]f the feature
    that creates the commercial success was known in the
    prior art, the success is not pertinent.”).
    Similarly, Western Union failed to establish that in-
    vestments made by itself and by MoneyGram in develop-
    ing formless money transfer systems different from
    Orlandi Valuta have any relation to the patentable fea-
    tures of the claimed inventions. Western Union points to
    payments in the amount of $240,000 that MoneyGram
    made to Cambridge Technology Partners (“Cambridge”)
    for consulting services as proof of such investments.
    WESTERN UNION   v. MONEYGRAM                             24
    However, MoneyGram presented evidence at trial that
    MoneyGram’s payments to Cambridge were for consulting
    services targeted toward reinventing the entire Money-
    Gram system, only part of which was addressing chal-
    lenges involved in adopting a formless system. Western
    Union failed to rebut that testimony, or offer any other
    evidence that demonstrated that Cambridge’s services
    were dedicated to developing the inventions claimed in
    the patents in suit. Mere attorney argument that both
    parties refused to adopt the Orlandi Valuta system spe-
    cifically because it was lacking the innovative aspects of
    the claimed inventions is not evidence that can support a
    finding of nonobviousness. See Perfect Web, 587 F.3d at
    1332 (rejecting a nonobviousness position that was
    “merely attorney argument lacking evidentiary support”).
    Thus, we find that the district court’s reliance, in finding
    nonobviousness, on the amount of time and money that
    both parties had spent on developing formless systems
    was misplaced.
    Moreover, weak secondary considerations generally do
    not overcome a strong prima facie case of obviousness.
    See Media Techs. Licensing, LLC v. Upper Deck Co., 
    596 F.3d 1334
    , (Fed. Cir. 2010), cert. denied, 
    2010 WL 2897876
     (Oct. 04, 2010) (“Even if [the patentee] could
    establish the required nexus, a highly successful product
    alone would not overcome the strong showing of obvious-
    ness.”); Leapfrog Enters., 
    485 F.3d at 1162
     (holding that
    the objective considerations of nonobviousness presented,
    including substantial evidence of commercial success,
    praise, and long-felt need, were inadequate to overcome a
    strong showing of primary considerations that rendered
    the claims at issue invalid). Here, where the inventions
    represented no more than “the predictable use of prior art
    elements according to their established functions,” KSR,
    
    550 U.S. at 417
    , the secondary considerations advanced
    25                           WESTERN UNION   v. MONEYGRAM
    by Western Union are inadequate to establish nonobvi-
    ousness as a matter of law.
    Thus, we conclude that the asserted claims of the
    ’203, ’747, and ’309 patents would have been obvious as a
    matter of law and therefore reverse the district court’s
    denial of JMOL of nonobviousness. In light of our disposi-
    tion, we do not reach issues of claim construction and
    infringement.
    CONCLUSION
    We have considered Western Union’s remaining ar-
    guments and do not find them persuasive. Accordingly,
    the judgment of the district court is
    REVERSED.
