Before NEWMAN, LOURIE, and RADER, Circuit Judges.

Opinion for the court filed by Circuit Judge RADER. Dissenting opinion filed by Circuit
Judge NEWMAN.

RADER, Circuit Judge.

       After a bench trial, the United States District Court for the District of

Massachusetts declared all of Agfa Corporation’s asserted patents unenforceable for

inequitable conduct. Agfa Corp. v. Creo Prods., Inc., Civil Action No. 00-10836-GAO

(D. Mass. Oct. 5, 2004) (Judgment) (judgment incorporating the trial court’s earlier

Findings of Fact, Conclusions of Law and Order for Judgment dated Aug. 24, 2004

(Decision)). Agfa challenges that result and also appeals the trial court’s order granting

the defendants’1 request that inequitable conduct be tried to the court, prior to a jury trial

on the other issues in the case. Agfa Corp. v. Creo Prods., Inc., Civil Action No. 00-

       1
            The defendants, now appellants, include: Creo Prducts, Inc., Creo, Inc.,
CreoScitex America Corp., CreoSSU Inc., Scitex Corp. Ltd., Scitex Development Corp.,
and Scitex America Corp. The court will collectively refer to these parties as “Creo.”
10836-GAO (D. Mass. July 16, 2003) (Bench Trial Order). Finally, Agfa appeals the trial

court’s award of attorney fees under 35 U.S.C. § 285. Judgment (incorporating the trial

court’s Award of Attorneys’ Fees and Costs, dated Oct. 5, 2004 (Attorney Fees

Decision)). Because the trial court did not err in any of those decisions, and because

this court agrees with the trial court’s claim construction of the one disputed claim term,

this court affirms.

                                             I.

       Large scale printing typically uses presses with plates made of materials such as

aluminum or polyester.      Conventionally, those plates are formed with a two-step

method.    The first step places a desired image on polyester film.        The next step

transfers that image to the printing plate. A light-sensitive chemical emulsion on the

plate often facilitates that transfer.   Mounted on the printing press, the plate then

reproduces images in a conventional manner.

       Unlike that conventional technique, “computer-to-plate” (CTP) systems take a

desired image, which can include both written and graphic content, and transfer that

image directly from a computer onto the plate. These plates made with a CTP system

then substitute for conventionally formed plates. CTP systems offer clear advantages

over conventional methods of forming printing plates.

       Agfa owns U.S. Patent Nos. 5,655,452 (the ’452 patent); 5,738,014 (the ’014

patent); 5,788,455 (the ’455 patent); 5,791,250 (the ’250 patent); 5,992,324 (the ’324

patent); and 6,000,337 (the ’337 patent). Those patents claim various features of Agfa’s

CTP system, i.e., its “Galileo” system. As taught in the asserted patents, Agfa’s Galileo

system further improves CTP automation by facilitating the creation of multiple plates of

05-1079                                      2
different sizes. Agfa’s patents all feature the same specification and drawings. Figure 1

of the ’452 patent, reproduced below, is representative of Agfa’s patented system.

As shown in that figure, CTP system 10 includes a computer 12 and image processor

14 linked to a platesetter 16. The platesetter includes a plate handler 18 having a

number of cassettes 24, which include stacks of plates 26.        During operation, the

handler 18 can move the cassettes up or down such that a “picker” 28 can access any

particular individual plate. Each cassette can include up to 100 plates, each separated

05-1079                                    3
from the adjoining plates by a protective “slip sheet,” which is automatically removed by

a slip sheet removal mechanism 25. While each cassette contains plates of the same

size, plate size can differ from cassette to cassette. Thus, during operation, the “picker”

can change plate size by selecting a different cassette.

       Because the plates are light sensitive, an operator loads the cassettes in a

darkroom.     After receiving the cassettes, the system operates without human

intervention. The system selects a plate and transfers it to the imaging engine 22. The

imaging engine prints an image directly onto the plate. The claim construction dispute

in this case, however, concerns the plate handler 18. More specifically, as discussed

below, the claim construction dispute concerns the meaning of the term “stack” that

appears in every asserted claim.

       Agfa and Creo compete in the CTP market. Agfa sued Creo alleging that Creo’s

CTP system infringed all of Agfa’s Galileo patents.        As a defense, as well as a

counterclaim, Creo asserted that all of Agfa’s Galileo patents are unenforceable due to

Agfa’s inequitable conduct before the United States Patent and Trademark Office

(PTO). According to Creo, Agfa wrongfully declined to disclose material prior art to the

PTO during prosecution of Agfa’s asserted patents. Specifically, Creo contended that

Agfa did not disclose at least three prior art systems, the Creo Platesetter 3244, the

Barco LithoSetter, and the Gerber Cressent/42. Creo further asserted that this prior art

was more relevant to Agfa’s applications than the single reference discussed in the

specification common to all of Agfa’s applications, a U.S. Patent on computer-to-film

printing. Decision, slip op. at 24-25.

05-1079                                     4
         The district court severed the inequitable conduct issue from the rest of the case,

and, over Agfa’s objection, conducted a bench trial on that issue. At the conclusion of

that trial, the district court declared all of Agfa’s patents unenforceable. The district

court further concluded that Agfa’s inequitable conduct rendered the case exceptional

and awarded attorneys’ fees under 35 U.S.C. § 285.

                                              II.

         “The constitutional question of whether a party is entitled to a jury trial is a

question of law,” subject to review without deference. Tegal Corp. v. Tokyo Electron

Am., Inc., 257 F.3d 1331, 1339 (Fed. Cir. 2001). In this appeal from a bench trial on

inequitable conduct, this court reviews the trial court’s findings of materiality and intent,

the underpinnings of inequitable conduct, for clear error. Bruno Indep. Living Aids, Inc.

v. Acorn Mobility Servs., Ltd., 394 F.3d 1348, 1351 (Fed. Cir. 2005) (citing Kingsdown

Med. Consultants, Ltd. v. Hollister, Inc., 863 F.2d 867, 872 (Fed. Cir. 1988)). This court

reviews the ultimate determination of inequitable conduct for an abuse of discretion. Id.

The trial court’s claim construction, part of its materiality determination, receives plenary

review. Cybor Corp. v. FAS Techs., Inc., 138 F.3d 1448, 1456 (Fed. Cir. 1998) (en

banc).     An award of attorney fees under 35 U.S.C. § 285 involves a two-part

determination.     This court reviews the trial court’s decision to declare the case

exceptional for clear error. Forest Labs., Inc. v. Abbott Labs., 339 F.3d 1324, 1328

(Fed. Cir. 2003). Where a trial court has found a case exceptional, its decision to award

attorney fees under § 285 is reviewed for an abuse of discretion. Id. (citing Cybor, 138

F.3d at 1460).

05-1079                                       5
          A.    JURY TRIAL ISSUE

          Procedurally, this case is almost indistinguishable from Gardco Manufacturing,

Inc. v. Herst Lighting Co., 820 F.2d 1209 (Fed. Cir. 1987). In Gardco, the plaintiff

sought a declaratory judgment on the asserted invalidity, unenforceability, and non-

infringement of a patent. Id. at 1210. In the unenforceability and invalidity accusations,

the prior art was the defendant-patentee’s own prior products, which were not disclosed

to the PTO during examination. See id. at 1211, 1213. The defendant counterclaimed

for infringement and demanded a jury trial. Id. The trial court in Gardco then separated

the inequitable conduct issue for trial without a jury. At the same time, the district court

postponed for later, if necessary, a jury trial on infringement and invalidity. Id. at 1210.

The bench trial on inequitable conduct determined that the asserted patent was not

enforceable. Id. For that reason, the trial court did not impanel a jury.

          Gardco differs from this case in only two ways. Due to the declaratory judgment

posture, the Gardco parties were arranged differently, i.e., with the accused infringer as

plaintiff rather than defendant. Gardco also featured inequitable conduct as a separate

claim rather than as a defense to infringement. Neither of those differences has any

bearing on the question of the right to a jury trial. See In re Tech. Licensing Corp., 423

F.3d 1286, 1288, 1291 (Fed. Cir. 2005) (right to jury trial is examined without regard to

the alignment of the parties or the posture of the issue, i.e. a defense or separate

claim).     Thus, this court confronts the same situation that Gardco presented nearly

twenty years ago. At that time, this court sustained the trial court’s approach. Gardco,

820 F.2d at 1213. This court, as it must, sustains the Gardco reasoning in this case.

05-1079                                      6
Nevertheless, Agfa presents two distinct reasons for this court to depart from Gardco.

This court declines that invitation.

       In the first place, contrary to Agfa’s assertion, Gardco is consistent with Supreme

Court precedent.      In Beacon Theatres, Inc. v. Westover, 359 U.S. 500 (1959), the

Supreme Court explained that a trial judge could not conduct a bench trial (and preclude

a jury trial) on equitable declaratory relief claims where that trial would resolve

“common” issues with a claim subject to jury resolution. 359 U.S. at 503-04. In Beacon

Theatres, the declaratory judgment plaintiff sought to raise essentially the same antitrust

issues for which the declaratory judgment defendant sought a jury trial.         Id.   The

Supreme Court declined to limit the declaratory judgment defendant’s jury trial rights

solely “because Fox took advantage of the availability of declaratory relief to sue

Beacon first.” Id. at 504. Beacon Theatres specifically noted that both the petitioner’s

claim and the declaratory relief claim involved “a common issue.” Id.

       This case involves issues of inequitable conduct (including the materiality of the

undisclosed prior art) and validity. Although these issues overlap to some degree, they

are not “common” issues as in Beacon Theatres. Because this case does not involve

“common” issues, this court need not apply the Beacon Theatres rule to honor Agfa’s

jury trial request.   Beacon Theatres did not use the term “overlapping.”       While the

inequitable conduct and validity questions in this case overlap in the consideration of

some aspects of the same relevant evidence, they do not involve a common issue. As

Gardco explained:

                     The simple fact is that a patent may be valid and yet
              be rendered unenforceable for misuse or inequitable
              conduct. Similarly, a valid patent may be (in the abstract)
              infringed, that is, the accused device may fall within the

05-1079                                     7
              scope of the claim, but there will be no liability to the
              patentee when the patent is unenforceable. Thus the
              conduct-of-the-applicant-in-the-PTO issue raised in the
              nonjury trial and the separated infringement/validity issues
              are distinct and without commonality either as claims or in
              relation to the underlying fact issues.
820 F.2d at 1213 (footnote and emphasis omitted).

       This Gardco reasoning governs even in the face of 37 C.F.R. § 1.56(b). In that

regulation, the PTO defines materiality as including information that establishes “a prima

facie case of unpatentability.” 37 C.F.R. § 1.56(b)(1). Even though the definition of

materiality, i.e., “a prima facie case of unpatentability,” may implicate some aspects of a

validity analysis, the issues of invalidity and materiality are still not common within the

legal construct of Beacon Theatres. As Gardco explained, a patent may be valid but not

enforceable. Thus inequitable conduct and validity are not “common” issues as Beacon

Theatres applied that concept.

       Moreover this court’s recent decision in Digital Control, Inc. v. Charles Machine

Works, 437 F.3d 1309, 1316 (Fed. Cir. 2006), explained that the PTO’s Rule 56 did not

supplant the earlier, and arguably broader, “reasonable examiner” standard for

materiality. Digital Control suggests as well that material prior art need not even be

invalidating prior art. Thus, under the reasonable examiner standard, material prior art

need not necessarily present a prima facie case of unpatentability. See id. at 1315

(Information is material “where there is a substantial likelihood that a reasonable

examiner would consider it important in deciding whether to allow the application to

issue as a patent.”) (quoting an older version of Rule 56). Because the materiality of

prior art is distinct from validity issues (without even considering the additional intent

requirement for inequitable conduct), this court’s earlier reasoning in Gardco remains

05-1079                                     8
sound. Materiality, therefore, does not present common issues with validity. Because

the issues are not “common,” the Beacon Theatres rule does not apply to protect Afga’s

jury trial request.

       Finally, Gardco explicitly considered and commented on the Supreme Court’s

decisions, including Beacon Theatres and the later decisions relating to inequitable

conduct factors and validity factors.      This panel could not depart from Gardco’s

reasoning even if it accepted the suggestion that materiality and validity present a

common issue, which it does not.

       In sum, although this case involves both issues of inequitable conduct and

validity, the decision to hold a bench trial on inequitable conduct does not preclude the

trial court’s later grant of a jury trial. The Beacon Theatres case does not mandate that

these are “common issues” that must be tried to a jury.

       Scire Facias

       Next, contrary to Agfa’s contentions, Gardco is consistent with some dicta in a

footnote in In re Lockwood, 50 F.3d 966 (Fed. Cir. 1995), vacated, 515 U.S. 1182

(1995).   In Lockwood, this court confronted a request for a jury trial in an action

involving the validity of two patents. Id. at 968. Lockwood explained that “[t]he thrust of

the [Seventh] Amendment was to preserve the right to jury trial as it existed in 1791.”

Id. at 971.    After citing Tull v. United States, 481 U.S. 412, 417 (1987), for the

proposition that the “Seventh Amendment ‘require[s] a jury trial on the merits in those

actions that are analogous to ‘Suits at common law,’’” Lockwood discusses the writ of

scire facias. 50 F.3d at 972, 974 n.9. In that discussion, the court remarks that “[t]he

contemporary analog of the writ is . . . an action for a declaration of unenforceability due

05-1079                                      9
to inequitable conduct not due to invalidity.” Id. at 974 n.9. This court in Lockwood next

states that actions corresponding to a writ of scire facias would give rise today to the

right to a jury trial. Id. Thus, in its footnote 9, Lockwood seemed to suggest that

inequitable conduct is analogous to a writ of scire facias, and because that writ would

have ultimately been decided by a jury in 1791, it was wrong for the trial court to decide

the inequitable conduct issue without a jury.       On close inspection, however, this

commentary in Lockwood does not disturb the Gardco reasoning.

       Admittedly, Lockwood’s analysis is easy to misread for the proposition that a writ

of scire facias is the historic analog of inequitable conduct. Lockwood, however, did not

speak in terms of historic analogs to inequitable conduct, it instead spoke of inequitable

conduct as a potential “contemporary analog” to scire facias. Id. Lockwood was not

examining inequitable conduct with an eye toward the right to a jury trial in 1791, rather

this court explained that a writ of scire facias was not so analogous to invalidity as to

require a jury trial. The footnote in Lockwood noted the language in older opinions

suggesting that the writ “was used to attack fraudulently obtained patents,” id., and, then

suggested in passing that inequitable conduct may serve as a better modern analog for

the ancient writ.

       This court’s use of the word “analog” in the footnote was unfortunate. In re

Technology Licensing made the same point, but with language less steeped in Seventh

Amendment jurisprudence. See 423 F.3d at 1290 (“The court in Lockwood specifically

stated that a proceeding on a writ of scire facias was not analogous to a suit for a

declaration of invalidity, but was more akin to an action for inequitable conduct.”)

(emphasis added, citation omitted). A closer analysis than was needed in Lockwood

05-1079                                     10
reveals that a writ of scire facias was not, in fact, a suit at common law analogous to

modern inequitable conduct.

         In eighteenth-century England, patents did not undergo an examination, at least

as “examination” proceeds in modern patent systems. See Edward C. Walterscheid,

The Early Evolution of the United States Patent Law: Antecedents (Part 4), 78 J. Pat.

Trademark Off. Soc’y 77, 83 (1996). Instead, the Sovereign granted patents based

solely on a petition and sworn affidavit from the inventor. In modern terms, the early

English patent system was a registration system.           See id. at 83-84.       Without

examination, nearly every defect in a patent resulted from some false representation

made by the patentee. See W. M. Hindmarch, A Treatise on the Law Relative to Patent

Privileges for the Sole Use of Inventions: And the Practice of Obtaining Letters Patents

for Inventions 230 (I.G. M’Kinley & J. M. G. Lescure 1847) (“[I]t is the duty of every one

obtaining a grant from the Queen, to see that she is correctly informed respecting the

grant.       [If] the Queen has been deceived in any material particular, by a false

representation or suggestions of the grantee, the patent will be wholly void.”) (citations

omitted).2 For example, the early English system would require a patentee to attest that

the invention was a genuinely new improvement, not already in the public domain. If

the evidence later showed the contrary, the court would characterize this defect as a

misrepresentation rather than as anticipation, the modern label for the same defect.

See id. at 164 (“Patentees . . . must have represented to the Crown that their inventions

         2
               Hindmarch is an American reprinting of the original British version. While
the date of the publication is 1847, its discussion and analysis, particularly with respect
to scire facias, includes citations to opinions issued during the mid-to-late eighteenth
century, i.e., at a time relevant to a Seventh Amendment analysis.

05-1079                                     11
were such improvements . . . and if their inventions were not such improvements as

represented . . . their patents are void by reason of the false representation or

suggestion made to the Crown.”) (footnote omitted). Thus, while “fraud” reasonably

describes the various bases for voiding eighteenth century patents, the actual history

discloses that the conduct of the patentee was not the focus of a decision to void a

patent.3   Finally, a litigant in England in the eighteenth century could also defend

against patent infringement by raising the grounds for voiding a patent through a writ of

scire facias without seeking the writ at all. Compare id. at 162 (“In an action brought

upon a patent[,] objections may be taken to it [including] that the Queen has been

deceived in some material particular.”) with id. at 231 (“The various objections which

can be taken to a patent for an invention, by a person against whom the patentee may

institute legal proceedings, have already been considered; and the law provides a

remedy for the public by action of scire facias, in which similar objections may be

taken . . . .”) (citation omitted).

       In sum, while a writ of scire facias might be more akin to inequitable conduct than

to invalidity, it certainly is not an historic analog that would trigger a Seventh

       3
              Even if “fraud” was perfectly synonymous with the grounds for voiding an
eighteenth century patent, it is not the equivalent of today’s inequitable conduct
defense. Common law fraud is not synonymous with the broader concept of inequitable
conduct. See Nobelpharma AB v. Implant Innovations, Inc., 141 F.3d 1059, 1069 (Fed.
Cir. 1998). Fraud has a number of indispensable elements: (1) a representation of a
material fact, (2) the falsity of that representation, (3) the intent to deceive (or an
equivalent recklessness), (4) justifiable reliance by the deceived party, and (5) injury to
the deceived party. Norton v. Curtiss, 433 F.2d 779, 792-93 (CCPA 1970). As noted
above, intent was not relevant to the decision to void a patent in eighteenth century
England, but rather the more standard doctrines of patentability applied. By the same
token, reliance and injury are not elements of today’s inequitable conduct defense.
Thus, while the label “fraud” may loosely cover both scenarios, they are nevertheless
distinct.

05-1079                                     12
Amendment right to a jury trial. This court has consistently treated inequitable conduct

as an equitable defense that may be adjudicated by the trial court without a jury.

Gardco remains the law of this circuit and governs this case.

           Contrary to the dissent’s analysis, this court today does not decide that the

factual issues underlying a charge of inequitable conduct must be adjudicated by a

judge.        Thus, the dissent’s observation that juries sometimes render verdicts on

unenforceability issues is entirely consistent with this court’s decision. The court today

merely confirms what has been the law at least since Gardco: a judge retains the

discretion to conduct a bench trial on the equitable issue of unenforceability in the same

case where invalidity is to be tried to a jury.

         B.       INEQUITABLE CONDUCT

                  1.    Claim Construction

         To reach inequitable conduct, the trial court necessarily construed the claims.

According to Agfa, the trial court misconstrued the term “stack,” common to all asserted

claims. As a representative example of the asserted claims, claim 1 of the ’452 patent

recites:

                        1.     A method for automatically selecting a plate for
                  imaging in an automated plate handler, comprising the steps
                  of:
                         a. automatically positioning a plurality of stacks of
                  plates stored in the plate handler and placing a stack of the
                  plate size required for an imaging job in an access position;
                         b. automatically separating and removing a single
                  plate from the stack of plates in the access position and
                  transferring the single plate out of the plate handler for
                  imaging; and
                         c. automatically removing a slip sheet from on top of
                  the stack of plates in the access position.

05-1079                                        13
’452 patent, col. 11, l. 66-col. 12, l. 11 (emphasis added). Agfa argues that the term

“stack” covers only a horizontal arrangement of plates, like those shown in figure 1 of

the ’452 patent, reproduced above.          The trial court disagreed, construing stack as

“encompassing a number of plates arranged together in an orderly fashion, regardless

of the orientation (horizontal or vertical) of the collection as a whole.” Decision, slip op.

at 22. This court perceives that the trial court’s construction, and its reasoning leading

to that construction, is sound.

       The trial court first consulted the ordinary meaning of “stack,” for which it cited a

dictionary definition. As this court explained in Phillips v. AWH Corp., the ordinary

meaning of some claim terms “may be readily apparent even to lay judges, and claim

construction in such cases involves little more than the application of widely accepted

meaning of commonly understood words.” 415 F.3d 1303, 1314 (Fed. Cir. 2005) (en

banc) (citation omitted). “In such cases, general purpose dictionaries may be helpful.”

Id.   This case falls squarely within those guidelines from Phillips.       The customary

meaning within this field of art does not limit the term “stack.”

       The meaning of the claim language does not limit “stack” to plates arranged one

on top of another. Accordingly, when a stack is tilted more than 45 degrees, it remains

a stack because the plates are still arranged in a top-to-bottom fashion. After all, the

top of a plate remains its top even when that plate tilts beyond 45 degrees. In other

words, the relationship of plates in a stack depends on the orientation of those plates

relative to one another. The orientation of the resulting stack from the vantage point of

elements outside the stack is irrelevant.

05-1079                                       14
       Moreover, nothing in the disclosures of the asserted patents suggests that

“stack” has any meaning in the art that would limit its scope to horizontal stacks. The

trial court buttressed its construction with the observation that three of the asserted

patents include dependent claims that further specify a horizontal (or other particular)

arrangement of the claimed stacks. See, e.g., ’250 patent, col. 12, ll. 16-18 (claim 2)

(“The method according to claim 1, wherein the stacks of plates stored in the plate

handler are positioned substantially horizontally.”).         Properly applying the claim

differentiation guideline in the context of dependent claims, the trial court correctly found

support for the proposition that those dependent claims suggest that the “stack”

standing alone is not limited to horizontally positioned stacks. See Curtiss-Wright Flow

Control Corp. v. Velan, Inc., 438 F.3d 1374, 1380 (Fed. Cir. 2006) (explaining the

presumption that independent claims do not include the limitations added by their

dependent claims).

       Similar to this court in Phillips itself, the trial court declined to limit these patent

claims to their preferred embodiment. The asserted patents indeed depict a horizontal

arrangement of stacks as the preferred embodiment. See, e.g., ’452 patent, figure 1

(reproduced above; elements 26 are the stacks). As noted, this court has repeatedly

rejected the contention that depiction of a single embodiment in a patent necessarily

limits the claims to that depicted scope. See Phillips, 415 F.3d at 1323. This case

illustrates again the reason for this court’s refusal to limit broader claim language to a

preferred embodiment in the patent specification. Of necessity, any depiction of any

stack will necessarily show that stack arranged in a particular manner. Nothing beyond

that depiction, however, limits the claim language—the defining portion of the patent

05-1079                                      15
document—to some particular orientation. Without any indication beyond the necessary

depiction to suggest limiting the invention to this single embodiment, the broader

language of the claims cannot carry that unexpressed and unintended (at the time of

patent drafting) limitation.

              2.      Materiality

       Unenforceability due to inequitable conduct requires proof of materiality and

intent by clear and convincing evidence. Kingsdown Med. Consultants, Ltd. v. Hollister

Inc., 863 F.2d 867, 872 (Fed. Cir. 1988).         Upon finding evidence that satisfies a

threshold measure of materiality and intent, the trial court then weighs that evidence to

determine that the equities warrant a conclusion of inequitable conduct. Molins PLC v.

Textron, Inc., 48 F.3d 1172, 1178 (Fed. Cir. 1995). In evaluating materiality, the trial

court followed the standard set forth in PTO Rule 56. That rule considers information

material to patentability when:

              [I]t is not cumulative to information already of record or being
              made of record in the application, and
              (1) It establishes, by itself or in combination with other
              information, a prima facie case of unpatentability of a claim;
              or
              (2) It refutes, or is inconsistent with, a position the applicant
              takes in:
                    (i) Opposing an argument of unpatentability relied on by
                    the Office, or
                    (ii) Asserting an argument of patentability.

37 C.F.R. § 1.56(b) (2004). The trial court found that the information withheld by Agfa

satisfied both parts (1) and (2) of that rule. With respect to prima facie unpatentability,

part (1) of Rule 56, the trial court focused on prior art CTP systems, patents, and

brochures. This prior art, taken alone or in combination, established a prima facie case

05-1079                                      16
of unpatentability for claims in each of Agfa’s asserted patents. The primary challenge

to the trial court’s materiality finding was that an incorrect claim construction caused

error in findings of materiality. Because, as discussed above, the trial court’s claim

construction was correct, these challenges of error fail.

       The trial court also found that the undisclosed prior art was inconsistent with

Agfa’s position during examination, and so was also material under part (2) of Rule 56.

Decision, slip op. at 45. During examination of two of Agfa’s applications, the examiner

requested clarification about the CTP technology described in the Background sections.

In particular, the examiner wished to know what aspects of the CTP technology

described in the Background were actually conventional. The trial court found that

Agfa’s responses to the examiner “were misleading in light of all the information [the

patent agent’s] had about the Undisclosed CTP References . . . . Indeed, [one of the

patent agents] admitted that he could not have made the arguments he did make in

response to the Examiner’s request if he had disclosed the Creo Platesetter 3244 or the

Barco LithoSetter . . . .” Id.

       On appeal, Agfa responds that Rule 56 “does not provide that a ‘misleading’

statement is material.” Appellant’s Brief at 56. This contention belies the weakness of

Agfa’s position.    The trial court did not find that the misleading statements were

material. Instead, the trial court found that undisclosed prior art was material because it

was inconsistent with Agfa’s misleading statements to the examiner during prosecution.

               3.     Intent

       Turning to intent, the trial court found abundant evidence from which to infer

Agfa’s culpable intent. Decision, slip op. at 41-45. For example, the evidence regarding

05-1079                                     17
Agfa’s knowledge of the Creo Platesetter 3244 was overwhelming: senior Agfa

employees, including an inventor named on all the asserted patents and the agents who

prosecuted the applications, attended an exposition put on by Agfa at which Creo’s

product was displayed; Agfa and Creo entered into a reseller agreement under which

Agfa agreed to sell Creo’s platesetter outside the United States; and Agfa distributed

brochures describing Creo’s products. Id. slip op. at 4-5. In the words of the trial court,

“[i]t was widely known within Agfa, including among the engineering and patent

departments, that Agfa was selling Creo’s Platesetter 3244, and that Creo was a

significant player in the field of CTP output devices.” Id. slip op. at 5. In addition to

Agfa’s particular familiarity with Creo’s platesetter, the trial court explained that Agfa

was well aware of other CTP prior art. According to the trial court, during development

of the Galileo project, Agfa kept a spreadsheet entitled “Overview of [CTP] Products.”

Id. slip op. at 7. The inventors common to all Agfa’s asserted patents possessed that

spreadsheet, including its information on the Creo Platesetter 3244, the Barco

Lithosetter, and the Gerber Crescent/42. Id. Based on Agfa’s extensive knowledge of

the prior art, the trial court reasoned that “[Agfa’s] failure to disclose information about

[the various] CTP systems to the [PTO] supports an inference of intent to deceive

because patentability arguments could not have been made had the withheld

information been disclosed.” Id., slip op. at 42.

       Both the evidence and the law support the trial court’s intent determination. This

court has held that a trial court may infer deceptive intent based on a showing that a

patentee withheld references with which it was intimately familiar and which were

inconsistent with its own patentability arguments to the PTO.        GFI, Inc. v. Franklin

05-1079                                     18
Corp., 265 F.3d 1286, 1275 (Fed. Cir. 2001) (citing LaBounty Mfg., Inc. v. United States

Int’l Trade Comm’n, 958 F.2d 1066, 1076 (Fed. Cir. 1992)). “[A] patentee facing a high

level of materiality and clear proof that it knew or should have known of that materiality,

can expect to find it difficult to establish subject good faith sufficient to prevent the

drawing of an inference of intent to mislead.” Id. (internal quotes and citation omitted).

       On appeal, Agfa questions the trial court’s intent finding based on its claim

construction argument. Specifically, Agfa argues that regardless of the proper meaning

of “stack,” it understood that term as applying only to horizontal stacks. Accordingly,

Agfa contends that it should not be charged with knowledge of materiality under a claim

construction it did not anticipate. Without knowledge of materiality, Agfa argues, the

trial court cannot properly infer intent.

       To the contrary, the trial court found Agfa’s assertion that its patent agents did

not appreciate the materiality of the undisclosed references, or that they unintentionally

withheld those references, not credible.       Specifically, the trial court relied on the

substantial documentation and internal discussions of those references in the design

and creation of the Galileo system. This court must defer heavily to the trial court’s

credibility determinations.    JVW Enters., Inc. v. Interact Accessories, Inc., 424 F.3d

1324, 1334 (Fed. Cir. 2005) (“[C]redibility determinations by the trial judge can virtually

never be clear error.”) (citations and internal quotes omitted).

       In addition, Agfa’s claim construction argument seems to assume that it had no

obligation to submit prior art that did not include horizontal stacks. In Agfa’s words:

“[w]hen stack is given its ordinary meaning of objects placed one on top of another, the

CTP references that disclose vertically-oriented plates clearly do not establish a prima

05-1079                                      19
facie case of anticipation.” Appellant’s Brief at 39 (emphasis added). Thus, Agfa seeks

to confine the material references that support an intent finding to only those references

that anticipate the claimed invention. Materiality is not synonymous with anticipation,

but instead embraces the broader concept of patentability.          Thus, even if Agfa’s

assertions about its understanding of “stack” during prosecution were accepted, the

undisclosed prior art would still have been material because some, but not all, of that art

included horizontally arranged stacks. See id. at 40.

       With respect to the ’324 patent, that patent is a continuation of the ’014 patent,

about which the district court made specific findings.      Thus, Fox Industries, Inc. v.

Structural Preservation Systems, Inc., 922 F.2d 801 (Fed. Cir. 1990), supports the trial

courts decision regarding the ’324 patent.       Fox Industries explains that inequitable

conduct “early in the prosecution may render unenforceable all claims which eventually

issue from the same or a related application.” Id. at 804. Later applications are, of

course, not always tainted by the inequitable conduct of earlier applications. See Baxter

Int’l, Inc. v. McGaw, Inc., 149 F.3d 1321, 1332 (Fed. Cir. 1998) (“[W]here the claims are

subsequently separated from those tainted by inequitable conduct through a divisional

application, and where the issued claims have no relation to the omitted prior art, the

patent issued from the divisional application will not also be unenforceable due to

inequitable conduct committed in the parent application.”).         The ’324 patent is a

continuation, not a divisional, of the ’014 patent. Furthermore, Agfa has not suggested

that the ’324 patent claims subject matter sufficiently distinct from its parent to preclude

the trial court’s inequitable conduct determination. Thus, the trial court’s inequitable

conduct analysis properly included the ’324 patent.

05-1079                                     20
              4.     Balancing

       Beyond the trial court’s findings of materiality and intent, Agfa also challenges the

trial court’s inequitable conduct determination based on those findings.              Agfa’s

argument is that, notwithstanding its detailed inequitable conduct analysis, the district

court did not perform a balancing of materiality and intent. This court, however, has no

doubt that the district court perceived this to be a case of intentional, large scale,

inequitable conduct. “The inequitable conduct established by the evidence here was

not incidental or sporadic, but thoroughgoing.” Decision, slip op. at 49. The district

court paints a picture of a group of engineers and patent agents who set out to design

their own version of their competitors’ products by attending trade shows and reviewing

literature, all the while taking notes and holding meetings to decide which features from

which printing presses would work well in Agfa’s Galileo system. Those same agents

then prepared and prosecuted the asserted patents, never sharing with the PTO any of

the information they had compiled about the products upon which they modeled their

system. The trial court thus found high levels of both materiality and intent, and did so

with respect to numerous undisclosed pieces of prior art. In such a case, the trial court

did not err by issuing its opinion without an express and detailed balancing analysis.

       Hoffmann-La Roche, Inc. v. Promega Corp., 323 F.3d 1354 (Fed. Cir. 2003), also

supports this result. In Hoffmann-La Roche, this court explained the importance of

determining “whether the material misrepresentations or omissions in question are

sufficiently serious in the light of the evidence of intent to deceive, to warrant the severe

sanction of holding the patent unenforceable.” Id. at 1372. In Hoffmann-La Roche, this

court remanded both because this court had not upheld all of the grounds for

05-1079                                      21
unenforceability and because the trial court had not addressed the weight of the various

findings of materiality and intent. Id. In this case, however, this court has upheld the

trial court’s findings of high levels of both materiality and intent. With those findings

firmly established in this case, the district court’s less express balancing sufficed. In this

setting, Hoffmann-La Roche does not require more.

        C.    ATTORNEY FEES

        Finally, because this court affirms the trial court’s decision, Agfa’s argument

regarding the award of attorneys’ fees fails. In the words of the trial court: “Even among

the subset of ‘inequitable conduct’ patent cases, this one must be considered

exceptional.” Decision, slip op. at 49. This court affirms the trial court’s award of those

fees.

                                      CONCLUSION

        Because the trial court properly relied on this court’s Gardco decision when it

held a bench trial on inequitable conduct, and because Agfa has not shown that the trial

court committed any errors during that bench trial, this court affirms.

                                          COSTS

Before NEWMAN, Circuit Judge, dissenting.

       The panel majority holds that the factual questions of both intent to deceive and

materiality of deceptively withheld information are not subject to the jury right. This is a

departure from the established jury right, for materiality and intent are quintessential

questions of fact, and have been tried to a jury throughout the nation's history. There is no

basis for removing these factual questions from the jury when the jury is trier of fact. I

respectfully dissent from the court's holding that there is no right to a jury, and that the jury

demand can be rejected at the trial court's discretion.
The Constitution, the Common Law, and Precedent

       The panel majority's holding that there is no right to a jury as to the factual questions

of material misrepresentation and deceptive intent is contrary to history, tradition, the

Constitution, and precedent. The Seventh Amendment preserves the right to jury trial as it

existed at common law. See Laurence H. Tribe, American Constitutional Law 618 (3d ed.

1988). The question of whether a patent was obtained upon "false suggestion" to the

granting authority, that is, a material misrepresentation with deceptive intent, was tried to a

jury at common law.

       This debate concerning the jury right is not new to the Federal Circuit, as this court

sought to establish consistent patent law and practice. In In re Lockwood, 50 F.3d 966

(Fed. Cir. 1995), this court reviewed the history of jury trials and fraudulent patent

procurement, as remedied by the common law writ of scire facias. See Lockwood, 50 F.3d

at 974 n.9 ("The contemporary analog of the writ is thus an action for a declaration of

unenforceability due to inequitable conduct. . . . "), which was vacated when Mr. Lockwood

withdrew his jury demand, 515 U.S. 1182 (1995). Upon the jury's finding that patents "have

been obtained surreptitiously or upon false suggestion," the chancery court could cancel

patents granted by the Crown, the court sitting in its "ordinary" common law jurisdiction

rather than in its "extraordinary" equity jurisdiction.         See 3 William Blackstone,

Commentaries on the Laws of England 47 (1765-69) ("The ordinary legal court is much

more ancient than the court of equity. Its jurisdiction is to hold plean upon a scire facias to

repeal and cancel the king's letters patent, when made against law, or upon untrue

suggestions"); see also, e.g., A Systematic Arrangement of Lord Coke's First Institute of the

05-1079                                        2
Laws of England, 328 n.D (J.H. Thomas ed., London, S. Brooke 1818) (explaining the

common law jurisdiction of the court of chancery).

       Historically, Justice Story recognized the common law nature of the writ of scire

facias when he ordered a jury trial for issues of fact in Ex Parte Wood, 22 U.S. (9 Wheat.)

603, 614-15 (1824) ("[I]t is the opinion of the Court . . . that a peremptory mandamus issue

to the Judge of the District Court . . . that he award a process, in the nature of a scire

facias, to the patentees, to show cause why the patent should not be repealed . . . and that,

if the issue so joined be an issue of fact, then the trial thereof to be by a jury; if an issue of

law, then by the Court, as in other cases."). Issues of fraud, deception, and intent, are

traditional jury questions, throughout the nation's courts, e.g., Forsyth v. Vehmeyer, 177

U.S. 177, 180 (1900) ("Where the state court has decided that the action was for fraud and

deceit, and has held that in order to have maintained such action the fraud must have been

proved as laid in the declaration, it must be assumed that the verdict and judgment in that

action were obtained only upon proof and a finding by the jury of the fact of fraud.")

       The panel majority proposes that because patents were not "examined" in 18th

Century England, the common law has no relevance to fraud in patent examination.

However, in England the jury would find whether a patent was fraudulently obtained, as part

of the proceedings of the writ of scire facias. See Rex v. Arkwright (Kings Bench 1785)

(raising the issues of invalidity due to anticipation, and of misrepresentation). The court

charged the jury:

       Gentlemen of the jury, . . . . If the specification, in any part of it, be materially
       false or defective, the patent is against law, and cannot be supported.

05-1079                                         3
       I have discovered no support for the panel majority's version of history that in 18th

Century England "nearly every defect in a patent resulted from some false representation

made by a patentee," maj. op. at 11, but even if that is correct, it reinforces, rather than

negates, the traditional jury presence, for false statements by a patentee would have been

submitted to a jury in 18th Century England.

       The common law right was, without quibble, carried into early cases in the United

States. See, e.g., Grant v. Raymond, 31 U.S. 218, 240 (1832) (the trial court "instructed

the jury that the patent would not be void on this ground, unless such defective or imperfect

specification or description arose from design, and for the purpose of deceiving the public");

Delano v. Scott, 7 F. Cas. 378, 382 (E.D. Pa. 1835) (trial court charging the jury that "By

the terms of that section, if the specification of the patentee does not contain the whole

truth relative to his discovery; or contains more than is necessary, for the purpose of

deceiving the public; or if it was not originally discovered by the patentee; or he had

surreptitiously obtained a patent for the discovery of another person, judgment shall be

rendered for the defendant, and the patent shall be declared void").

       Many Federal Circuit decisions illustrate the jury role in finding disputed facts

concerning questions of material withholding and deceptive intent, as well as the ultimate

fact of whether these infractions warrant permanent unenforceability of the patent. The

panel majority's statement that "This court has consistently treated inequitable conduct as

an equitable defense that may be adjudicated by the trial court without a jury," maj. op. at

13, is confusing if not misleading, for the statement on its face is accurate, but the majority

then holds that there is no jury right and that the factual issues can be adjudicated and

balanced only by a judge, and that there is no right to a jury when such is demanded.

was unenforceable for inequitable conduct."); Lummus Indus., Inc. v. D.M. & E. Corp., 862

patent, was a 'moderately material' reference, and that the inventor and his attorneys had

been 'grossly negligent' in failing to call it to the attention of the Patent Office during original

examination.     Accepting those findings, the trial court concluded that there was no

inequitable conduct.");

       As the panel majority correctly points out, findings of deceptive intent often require

findings of credibility. Credibility is unequivocally the province of the jury. Reeves v.

Sanderson Plumbing Prods., Inc., 530 U.S. 133, 150 (2000) ("'Credibility determinations,

the weighing of the evidence, and the drawing of legitimate inferences from the facts are

jury functions, not those of a judge.'") (quoting Anderson v. Liberty Lobby, Inc., 477 U.S.

242, 255 (1986)). The question of whether the patent applicant intended to deceive the

patent examiner is a fact, for which a jury may be demanded.

       The decision now offered joins a few cases in which panels of the Federal Circuit

diverged from history and the weight of our precedent, as in Gardco Mfg., Inc. v. Herst

Lighting Co., 820 F.2d 1209 (Fed. Cir. 1987), Paragon Podiatry Lab, Inc. v. KLM Labs, 984

F.2d 1182, 1190 (Fed. Cir. 1993), where the panel rejected the right to a jury, and a few

other cases. This continuing conflict within our court's precedent disserves the public, as

does the selective citation in this opinion of only Gardco, ignoring the entire body of

contrary precedent, and leaving litigants and trial judges with the burdensome jousting here

illustrated.1 The panel majority misconstrues the Court's holding in Beacon Theatres, Inc.

v. Westover, 359 U.S. 500 (1959), where the Court held that factual elements in common

       1      The panel majority's characterization of this court's Lockwood decision as
"unfortunate" is unfortunate, for Lockwood is on sound foundation. If Lockwood is to be
rejected, such a change of precedent requires that the court speak with one voice.

with both legal and equitable issues or, in that case, subject to equitable remedy, could not

be deprived of the jury right as to the factual aspects. The Court made clear that when

there is judicial discretion it Amust, wherever possible, be exercised to preserve the jury

trial.@ Id. at 510-11. In Gardco a panel of this court found that there were no common

relevant elements in the specific circumstances of that case. In contrast, in the case at bar

where asserted misinformation is charged with being material to patentability and

deceptively withheld, these are questions of fact that are directly concerned with both

validity and enforceability. Thus the panel majority, in its ruling that the trial judge can

always exercise discretion and refuse to try these issues to a jury, misses the point that

when there is a jury right as to legal elements, as in Beacon Theatres, there is no discretion

to deny the jury right as to factual questions relevant to both the legal and equitable issues.

See also, e.g., Cabinet Vision v. Cabinetware, 129 F.3d 595, 600 (Fed. Cir. 1997).

The PTO's Rule 56

       Concern for fraud in obtaining patent rights grew with the growth of technology, as it

became apparent that there was an imbalance between the information known to inventors,

and the knowledge of patent examiners. See Precision Instruments Mfg. Co. v. Automatic

Maintenance Machinery Co., 314 U.S. 806 (1945). As judicial precedent showed the need,

the Patent Office established implementing regulations setting the obligations of patent

applicants.

       The panel majority further states, maj. op. at 8, that it need not follow the criteria of

the PTO's rule, 37 C.F.R. '1.56, as recently revised. That revision was adopted after public

hearings, and exploration of extensive experience as well as the needs and balance of

05-1079                                        8
patent examination.      That revision binds the PTO and, absent sound reason, the

Administrative Procedure Act requires this court to follow it uniformly, not selectively in

different parts of the same opinion. Compare maj. op. at 8, where the court endorses the

prior version of Rule 56, and op. at 16, where the court applies the present version.

The Claim Construction Issue

       I comment briefly on the claim term "stack" and its application by the majority to a

vertical, not a horizontal, array. The panel majority states that "when a stack is tilted more

than 45 degrees, it remains a stack because the plates are still arranged in a top-to-bottom

fashion. After all, the top of a plate remains its top even when that plate tilts beyond 45

degrees." Op. at 14. Perhaps at 45 degrees or even 60 degrees the top of a "stack" is still

a "top," but when the plates are lined up in parallel there is no longer a "top" plate, for the

plates are no longer "stacked."

       The claims and the entire descriptive text make clear that the invention is directed to

"substantially horizontal" plates that are stacked one upon the other. When the plates

stand vertically -- as in the prior art, and apparently in the accused system, there is no top

plate. I cannot agree with the panel majority that "stack" is correctly construed to include

the vertical alignment of the prior art.
