ORDER

VAN TATENHOVE, District Judge.

The Court takes up for consideration the claims of fourteen patents at issue in this suit that have contested constructions for the purpose of Construing those claims.^[1] The parties have filed a joint claim construction brief [R. 919]; opening briefs [R. 966 (Static Control, Pendl, and Wazana), 949 (Lexmark) ]; responses to the opposing parties' opening brief [R. 1007, 1010]; and replies [R. 1023, 1025].

I.

BACKGROUND

Briefly, the status of the parties is as follows: Lexmark is a large producer of printers and toner cartridges for its printers. SCC is "a leading supplier to toner cartridge remanufacturers." [R. 172 at 16, Case No. 5:02-571]. The remanufacturers, which include the other Counterclaim Defendants in this case, take used toner cartridges, repair them, refill the toner, et cetera and resell the cartridges to enduser consumers. SCC sells to the remanufacturers parts and supplies for reworking the used toner cartridges, such as replacement parts, toner, and microchips. [R. 1].

Lexmark and SCC first began litigation in this Court in 2002 when Lexmark filed suit against SCC, alleging, inter alia, that SCC's sale of "SMARTEK" microchips infringed on Lexmark's copyrighted "Toner Loading Programs." [R. 1, Case No. 5:02-571]. In 2004, SCC filed a declaratory judgment action, alleging, inter alia, that its new "re-engineered" microchips did not infringe on any of Lexmark's copyrights. [R. 1, Case No. 5:04-84]. The cases were ultimately consolidated with Case No. 5:04-84 as the lead case, and all citations in this Order refer to that lead case unless otherwise noted. [R. 140]. Lexmark filed a Counterclaim/Third Party Complaint to the 2004 litigation initiated by SCC, in which it alleged patent claims against SCC and the Counterclaim Defendant remanufacturers to this case. [R. 67]. These patent claims in Lexmark's Counterclaim form the basis of the claim construction process in which the Court currently engages.

The primary, though not only, theory on which Lexmark alleges direct patent infringement against the remanufacturers and active inducement of patent infringement against SCC is predicated on Lexmark's use of single-use restrictions on the majority of its cartridges at issue. These "restricted" cartridges have been commonly referred to as "Prebate cartridges" for the reasons that follow: Lexmark runs what it called at one time its "Prebate Program" and what now is referred to as the "Lexmark Return Program." [R. 594 at 3, n. 4]. In that program, Lexmark's customers buy printer cartridges at an up-front discount in exchange for the customer agreeing to use the cartridge only once and then return the empty cartridge only to Lexmark. According to Lexmark, Lexmark offers "`[r]egular' toner cartridge[s] for those customers who do not choose the Prebate/Cartridge Return Program toner cartridge[s] with [their] terms." [R. 2 at 8]. Therefore, "Prebate" is temporally the reverse of a rebate.

Over the years, the precise language of Lexmark's Prebate terms printed across the top of Prebate cartridge boxes has varied. [See, e.g., R. 573 at 3]. However, currently the terms read:

RETURN EMPTY CARTRIDGE TO LEXMARK FOR REMANUFACTURING AND RECYCLING

Please read before opening. Opening this package or using the patented cartridge inside confirms your acceptance of the following license agreement. This patented Return Program cartridge is sold at a special price subject to a restriction that it may be used only once. Following this initial use, you agree to return the empty cartridge only to Lexmark for remanufacturing and recycling. If you don't accept these terms, return the unopened package to your point of purchase. A regular price cartridge without these terms is available.

[R. 594, 3-4 (Lexmark has provided the Court with a demonstrative cartridge and cartridge box with the above Prebate language, as Lexmark represented that it would at Record 519 at 9, n. 13) ]. Including English, these terms are printed in six different languages. Id.

Lexmark's second theory of direct patent infringement is predicated on the idea that the first sale of cartridges in foreign nations does not exhaust Lexmark's patents on those cartridges in the United States. See Jazz Photo Corp. v. Int'l Trade Comm'n, 264 F.3d 1094, 1105 (Fed. Cir.2001) (citing Boesch v. Graff, 133 U.S. 697, 701-703, 10 S.Ct. 378, 33 L.Ed. 787 (1890)). Accordingly, Lexmark argues that regardless of whether a single use restriction reads on its cartridges, the Counterclaim Defendant remanufacturers of printer cartridges infringe upon the patents that read upon cartridges originally sold overseas by reselling them without license in the United States.

II.

DISCUSSION

A. Principles of Claim Construction

The current exercise the Court undertakes is that of claim construction. Title 35 U.S.C. § 112 requires that the written description of the invention, or "specification," in the patent, "shall conclude with one or more claims particularly pointing out and distinctly `claiming the subject matter which the applicant regards as his invention." "It is a bedrock principle of patent law that the claims of a patent define the invention to which the patentee is entitled the right to exclude." Innova/Pure Water, Inc. v. Safari Water Filtration Sys., Inc., 381 F.3d 1111, 1115 (Fed.Cir.2004) (citing Aro Mfg., Co. v. Convertible Top Replacement Co., 365 U.S. 336, 339, 81 S.Ct. 599, 5 L.Ed.2d 592 (1961)). Determining the scope and meaning of a claim is solely a matter of law for the Court to decide. Markman v. Westview Instruments, Inc., 517 U.S. 370, 372, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996).

Claim construction has two practical implications. First, construing the claim enables a fact finder to determine whether a patent may be invalid for failing to meet requirements of patentability. See Amazon. com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed.Cir.2001). The Court has already held that nine of the fourteen patents considered here are valid. [R. 1008 at 6-7]. In response to Lexmark's motion for validity on the nine patents, the opposing parties offered not even a scintilla of argument, let alone evidence, that any given claim was invalid for whatever reason. Id. This was despite the fact that the opposing parties knew precisely those ninety-three claims which Lexmark alleges were infringed. Id. Therefore, validity is only at issue with regard to the remaining five patents. The second function of claim construction is to determine whether an alleged infringer infringed on a patent by doing that which is covered by any of the patent's claims. Amazon.com, Inc. 239 F.3d at 1351.

The courts, especially the Court of Appeals for the Federal Circuit, have developed a body of law that instructs on how claims should be construed. The language of the claim itself is of paramount importance:

We begin our claim construction analysis, as always, with the words of the claim. The claim language defines the bounds of claim scope. "The claims define the scope of the right to exclude; the claim construction inquiry, therefore, begins and ends in all cases with the actual words of the claim." "The language of the claim frames and ultimately resolves all issues of claim interpretation."

Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1324 (Fed.Cir.2002) (citations omitted). That is not to say that the words of the claim are construed without reference to additional information.

One case, Phillips v. AWH Corp., is particularly well known for outlining the process of claim construction. 415 F.3d 1303 (Fed.Cir.2005). First, "[t]he words of a claim `are generally given their ordinary and customary meaning,'" which is the "meaning that the term would have to a person of ordinary skill in the art in question at the time of . . . the effective filing date of the patent application." Id. at 1312 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576; 1582 (Fed.Cir. 1996)). "In some cases, the ordinary meaning of claim language as understood by a person of skill in the art may be readily apparent even to lay judges, and claim construction in such cases involves little more than the application of the widely accepted meaning of commonly understood words." Phillips, 415 F.3d at 1314 (citing Brown v. 3M, 265 F.3d 1349, 1352 (Fed.Cir.2001)). When determining the meaning of claim terms and phrases, intrinsic evidence, consisting of the patent itself, including the specification and claims therein, and the prosecution history, if submitted, is the "the most significant source of the legally operative meaning of disputed claim language." Vitronics Corp., 90 F.3d at 1582. The specification is usually dispositive to the claim construction analysis. Id. The Court may also utilize extrinsic evidence, such as expert testimony and general or trade dictionaries, to assist in construction, but such evidence is subordinate to and may only be used to clarify intrinsic evidence. Phillips, 415 F.3d at 1317-18. Typically, repeated words or phrases in the patent are construed to have the same meaning. Id. at 1314.

A patent claim is introduced with a preamble. For instance, Claim 1 of Lexmark's Patent No. 5,634,169 begins with the preamble, "A cartridge for an electro-photographic machine," followed by the transitional term, "comprising," and then by the body of the claim. [R. 966, Attach. 1]. A preamble may or may not contain language that limits the claimed invention. Whether the preamble limits is an issue that the Federal Circuit addressed in Pitney Bowes, Inc. v. Hewlett-Packard Co.:

If the claim preamble, when read in the context of the entire claim, recites limitations of the claim, or, if the claim preamble is "necessary to give life, meaning, and vitality" to the claim, then the claim preamble should be construed as if in the balance of the claim. Indeed, when discussing the "claim" in such a circumstance, there is no meaningful distinction to be drawn between the claim preamble and the rest of the claim, for only together do they comprise the "claim". If, however, the body of the claim fully and intrinsically sets forth the complete invention, including all of its limitations, and the preamble offers no distinct definition of any of the claimed invention's limitations, but rather merely states, for example, the purpose or intended use of the invention, then the preamble is of no significance to claim construction because it cannot be said to constitute or explain a claim limitation.

182 F.3d 1298, 1305 (Fed.Cir.1999) (citations omitted).

Issues of claim construction additionally arise due to Paragraph 6 of Title 35 U.S.C. § 112. That section provides that:

An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.

The Federal Circuit has held when the Court should find that an inventor has invoked the means-plus-function format:

The use of the word "means" "triggers a presumption that the inventor used this term advisedly to invoke the statutory mandate for means-plus-function clauses." This presumption may be overcome in two ways. First, "a claim element that uses the word `means' but recites no function corresponding to the means does not invoke § 112, P 6." Second, "even, if the claim element specifies a function, if it also recites sufficient structure or material for performing that function, § 112, P 6 does not apply." A claim term recites sufficient structure if "the `term, as the name for structure, has a reasonably well understood meaning in the art.'" The mere use of the word "means" after a limitation, without more, does not suffice to make that limitation a means-plus-function limitation.

Allen Eng'g Corp. v. Bartell Indus., 299 F.3d 1336, 1347 (Fed.Cir.2002) (citations omitted).

B. The Parties' Arguments with Regard to the Claims in Issue

Lexmark argues that all of the terms or phrases that have been marked jointly for construction are "simple and strait forward" and that no further construction of the terms is required or appropriate for "[a] person of ordinary skill in the relevant art" to know precisely what the claim limitations mean. [R. 949 at 5]. According to Lexmark, the unnecessary nature of claim construction in this matter is exacerbated by the Counterclaim Defendants failure to "yet provide their invalidity and non-infringement contentions, despite numerous Court orders to do so." Id. at 34.

The Counterclaim Defendants rebut Lexmark's argument by stating that the Court must resolve disputed claim constructions. By letting terms speak for themselves, the Counterclaim Defendants argue that Lexmark is improperly attempting to allow the jury to implicitly conduct its own claim construction. [R. 1007 at 1-3]. They continue, "Lexmark has defaulted. It has not advocated constructions of the disputed claim terms." Id. at 4. The Court disagrees. Rather, the Court believes that there is no real dispute with regard to many, if not most, of the claim limitations at issue.

A simple illustration should demonstrate the lack of real conflict in the current case: assume a claim limitation is the term "dog." One party argues that, based on intrinsic evidence, a "dog" must be construed as "weighing less than 50 lbs." Accordingly, that party argues that its accused dog is non-infringing because the accused dog weighs 30 lbs. This would be an exercise in construction. However, arguing that "dog" ought to be construed as "canine" is no construction at all. The terms are mere synonyms that leaves the Court to wonder what the point is. Under what circumstance would an accused dog infringe but an accused canine would not? Ultimately, there is no dispute in the first instance regarding the claimed term. This is exactly what SCC and the Remanufacturers have done over and over again with regard to their proposed claim construction For example, they merely call a "sump" a "receptacle," or they call the "left side" the "region to the left of the center line."

The Court has nevertheless gone through the claim construction process as listed below in the following manner: with regard to some of the Counterclaim Defendants' proposed constructions, a practical effect of the construction, with potential infringement implications, is implicitly ascertainable, though admittedly speculative. Nevertheless, the Court has construed these terms. In other instances, this is not the case, and the Court reiterates that there is really no dispute at all. The Counterclaim Defendants' exhortation to attach a synonym to self-defined and simple words invites a meaningless result that mocks the notion of construction.

Finally, the Court addressed, the necessity of a claim construction hearing in this matter at the Final Pretrial Conference on April 24, 2007. See Markman v. Westview Instruments, Inc., 517 U.S. 370, 116 S.Ct. 1384, 134 L.Ed.2d 577 (1996). All the parties agreed that a claim construction hearing was unnecessary in this matter, except that the parties were amiable to a hearing if the Court thought it appropriate. The Court concurs with the parties that a hearing on claim construction is unnecessary, as this issue has been heavily briefed in writing on the record.

C. Construction

The Court below construes the terms or phrases in claims over which the parties disagree. The parties filed a joint claim construction brief at Record No. 919. In that brief, in table format, the parties listed the relevant claim limitation and then underlined terms over which there was dispute as to construction. In the next column, Lexmark submitted its proposed construction, and in a third column, SCC and the Remanufacturers submitted their proposed construction. In the below chart, the Court makes its own constructions of the claims, utilizing the above principles of claim construction and considering the parties' proposals. The Chart below is keyed to the parties' joint claim construction brief. [R. 919]. For instance, the parties listed some claim limitations which the parties agreed need no construction. The Court assumes this was done to put other claim limitations in context, and accordingly, the Court has duplicated the claim' limitations for which "no construction [is] necessary" below:

C.R. Bard, Inc. v. M3 Sys., Inc., 157 F.3d
1340, 1350 (Fed.Cir.1998). Therefore, the
preamble is not a claim limitation requiring
construction. Id.; see also NTP, Inc. v. Research
In Motion, Ltd., 418 F.3d 1282, 1305-06
(Fed.Cir.2005). It would be inappropriate
to construe the preamble to mean that the

for words is not necessarily claim construction.
"Receptacle" is no more defined than
"sump." Furthermore, it is fantastical to the
Court to believe that calling a "sump" a "receptacle"
would have any practical effect to
infringement issues in this case (or validity
issues, if such issues were still relevant regarding
this patent).
This limitation is construed as follows: "a
sum carries a quantity of toner."

wheel reader when said cartridge is in a home                   printer to have effect. While a cartridge may
position in an electrophotographic machine;                     require a printer to execute its intended function
and                                                             (and vice versa), the invention is structurally
complete without the printer (See
claim 1). Accordingly, this is not like a method
claim, and the Court finds that there is
really no dispute over the plain meaning of
"said encoder wheel positioned for mating
coaction with a code wheel reader."
SCC does not offer a construction of "home
position," and thus the Court finds that that
part of the limitation is not in substantive
dispute, as the limitation speaks for itself.

machine, when said cartridge is installed in                    extent that the Counterclaim Defendants'

reality, it is improper to read in limitations on

a limitation here, because for example, information
about the amount of toner in the
cartridge is not static — it changes as toner is
used. [See R. 949 at 106]. This argument has
no merit, because the specification specifically

classifies "the amount of toner remaining"
information as something different than "preselected
cartridge characteristics." Col. 5,

The specification indicates that 50-200 microns
is a desired result: "By the correct
combination ... a surface layer thickness of

produced." Col. 4, lines 57-62. However,
nothing suggests that 50-200 microns is an
implicit limitation. Accordingly, the claim

C.U.S. Patent No. 5,758.233 ("Locatins. Surfaces")

C.R. Bard, Inc. v. M3 Sys., Inc., 157 F.3d
1340, 1350 (Fed.Cir.1998). Therefore, the
preamble is not a claim limitation requiring
construction. Id.; see also NTP, Inc. v.
Research In Motion, Ltd., 418 F.3d 1282,
1305-06 (Fed.Cir.2005). It would be inappropriate
to construe the preamble to mean that

urge the adoption of a construction, "advantageous
amount," but that is no more defined
than "controlled," and thus the Court rejects
that construction. If the Court were to follow
the Counterclaim Defendants' proposal, then
the Court's construction would itself require
construction. Neither party suggests or proposes
that a "controlled amount" ought to be
defined as a certain range of measurement
and thus neither does the Court.
Regarding SCC/Reman.'s proposed construction
of "first unitary assembly," nothing suggests
that "unitary" in this context means
"indivisible." SCC's word choice of "indivisible"
is bootstrapped from a general dictionary,
when the specification informs that the
limitation of "unitary" is more akin to a requirement
of being "attached together." Col.
8, Lines 24-30. Furthermore, the claim limitation
itself defines what a "first unitary assembly"
is. Lexmark's construction embodies
this meaning, and thus the Court adopts
that construction as follows: "a toner hopper
and a rotatable developer roller are mounted
together as a first unitary assembly and the
developer roller receives toner in controlled
amounts from the toner hopper."

embodiment. See Figs. 1 and 2, Nos.

toner from the photoconductor drum. Col. 4,
line 65 — Col. 5, line 4. The Court agrees
with Lexmark that "a chamber for cleaning"
has an analogous meaning to "a laundry room
for washing clothes." [R. 949 at 64]. Because
SCC's proposed construction might be
read to require the cleaner chamber to actually
perform the task of the blade, that construction
is rejected.

general dictionary, when the specification

construes this claim limitation as not claiming

C.R. Bard, Inc. v. M3 Sys., Inc., 157 F.3d

except that the specification informs that a
controlled amount is not "excessive." Col. 9,
lines 13-26. The Counterclaim defendants

urge the adoption of a construction, "advantageous

than "controlled," and thus the Court rejects
that construction. If the Court were to follow
the Counterclaim Defendants' proposal, then
the Court's construction would itself require
construction. Neither party suggests or proposes
that a "controlled amount" ought to be

and thus neither does the Court.

unjustly limit the claim.
The Counterclaim Defendants construction of
"slots in said imaging apparatus," which is
"an imaging apparatus that includes slots," is
inappropriate because it limits an unclaimed
apparatus (e.g. a printer).
The Court understands the "substantially
continuous slots" to be illustrated by the unclaimed
space formed by guides in a printer,
Fig. 10, No. 293, 297, The Court sees no
reason to import SCC's construction of "connected"
because that begs the question,
"connected to what?" It would certainly be
inappropriate to somehow suggest that the
members must be connected to the unclaimed
slots. Rather, the claim itself makes
clear that the purpose of the claimed "substantially
continuous" members are to be
guided by unclaimed substantially continuous
slots.
Accordingly, having rejected the Counterclaim
Defendant's constructions to the extent
they may have any practical consequence, the
Court finds that there is no substantive dispute
over this limitation.

are not limited to the preferred embodiment,
the specification may support SCC's construction
(even though the specification is only
evidence of a claim limitations, rather than
limiting itself).

does not address this claim limitation in its

[R. 1010 at 34]. Given Lexmark's assertion
that "right side" requires "no further construction,"

Why SCC finds it necessary for the Court to
construe the word "imaging apparatus" as a
"printer" here, in light of the myriad uncontested
uses of the word "imaging apparatus"

it is hereby adjudged that "imaging apparatus"

representing cartridge characteristic information.              limitation pursuant to 35 U.S.C. § 112, ¶ 6.
Although the word "means" is not followed by
function, it is apparent that the function here
is "coding." The claim could equally read,
"means for coding." Because the means is
not followed by sufficient structure or material
for performing the coding, this claim falls

within § 112, ¶ 6. The structure/material for
performing the coding, also the "coding indicators",
is ostensibly (from the specification)
"radially extending ... slots or windows,"
Col. 8, lines 31-34, 43-44, or "reflective material,"
Col. 20, line 64-65, or notches and
equivalents of the aforementioned.
Cartridge characteristic information is construed
as "information about the cartridge."
Though it may not be necessary to construe
this phrase, Lexmark states that it "has no
issue with ... [the] proposed construction
... but notes that it adds nothing of value,
..." [R. 949 at 103].

argues that this construction imports
limitations from the specification. The Court
disagrees, and finds that the specification is
merely confirmative evidence that the claim is
limited in the manner in which SCC proposes
(absent a grease requirement). See Fig. 12,
in which the coil spring clutch is the only
frictional drag element disclosed anywhere
(see Claim 2, regarding the coil spring
clutch). SCC also argues that the specification
regarding grease — "The drag from element
is uniform because of the grease" —
requires the mechanism to be in combination
with grease. Col. 9, lines 58-61. The Court
disagrees. "Uniform" describes "frictional
drag," not "element." The structure itself
must not be eased to be claimed.

definition of "coil spring clutch" in the specification.
Col. 2, lines 51-55. The Court rejects
Lexmark's argument that construing a
term according to its definition outlined in the
specification, at least under these circumstances,
improperly imports limitations into
the claim. Lexmark's argument degrades the
high evidentiary weight that should be afforded
the specification to determine limits embodied
in the claim itself. Nevertheless,
"grease" is irrelevant to the claim limitation.

copolymer.                                                      polyorganosiloxane sealant." The sealant
version has the consistency of a paste or
pliable caulk, so the claim is construed as
follows: "polyorganosiloxane having the consistency
of a paste of pliable caulk." This is
not inconsistent with E.I. du Pont de Nemours
& Co. v. Phillips Petroleum Co., 849
F.2d 1430, 1433 (Fed.Cir.1988), because the
Court does not impose a consistency requirement;
rather "sealant" should be construed
to have effect, and that effect is that the
sealant is not the wax copolymer outlined in
the specification.

Def.s' version) or whether "each chemical
component in the layer essentially retains its

[R. 1025 at 15 (citing Col. 4, 65-67)], the

said toner cartridge includes a sump for carrying
a supply of toner and
an agitator rotatably mounted in said sump,                     The claim is construed as follows: "the agitator
is mounted in the sump in a manner such
that it can be rotated." SCC's proposed construction,
"supported to rotate with the encoded
device," is inappropriate because it
could impose an extraneous limitation that
the agitator and the encoded device must
rotate conjointly.

end, said plate being coupled to said first end                 sump. Beyond that, SCC's proposed construction
of said agitator and a torque sensitive coupling                of "fastened to" is a synonym that

said first paddle about the fixed first axis:
said toner reservoir having a second portion                    The Court construes this claim to permit
in which the toner therein is not engaged by                    contact between the first paddle and toner in
said first paddle during each revolution of                     the second portion of the toner reservoir.

result, nothing about the limitation suggests
that contact between the first paddle and
toner in the second portion of the toner reservoir
cannot or does not ever happen. Because
SCC's proposed construction suggests
otherwise, it is rejected.

is rejected, because it requires "support
arms on the second paddle that are
longer than the radius of the inner surface of
the longitudinal wall." Rather, said support
arms in combination with the mating structure
of the first paddle should be longer than
the radius of the inner wall. [R. 949 at 137-38];
Fig. 2. Under the Counterclaim Defendants'
construction, with reference to Fig. 2,
the support arms at Nos. 41 and 42 would
have to be longer than support struts, illustrated
at No. 29, which run the length of the
"mating structure." This construction would
be in error.

SCC's construction potentially improperly
limits the claim as requiring that the
second toner moving element not contact any
toner in any other portion of the toner reservoir,
that construction is rejected. See claim
1 above.

Nos. 10e and 10d.
The use of the words "rotary member" is
additionally not indefinite, nor could a reasonable
person so find. The preferred embodiment
may be seen at Fig. 3, No. 10d. Nevertheless,
any indefiniteness arguments with
regard to the claims in issue in the '383
patent are moot, for the Counterclaim Defendants
failed to raise indefiniteness contentions
in response to a motion for summary
judgment by Lexmark on, inter alia, the '383
patent's validity [R. 1008].

developer roll, said rotary seal portion incorporating
ridges set at an angle across its face
adjacent to the surface of said developer roll,
said ridges being from about 0.05 to about 0.5
millimeters in height and running at an angle
to the developer roll process direction so as to
push toner away from the edge of said developer
roll in use;

and said blade member.

Having considered the parties' claim construction pleadings, it is hereby ORDERED that said claim limitations in issue are construed or the issues pertaining thereto otherwise disposed of in accordance with the above table.

NOTES

[1] There were originally sixteen patents at issue in this suit; however, the Court determined that two of Lexmark's design patents were invalid and thus only fourteen patents in suit are currently relevant for purposes of claim construction. [R. 1008].
