Opinion

DECISION AND ORDER

WILLIAM C. GRIESBACH, District Judge.

Presently before me in this patent infringement action are cross-motions for *797 summary judgment on the issue of inequitable conduct. Also pending are Plaintiffs two motions to dismiss the inequitable conduct counterclaims, a motion to amend the complaint, a motion for reconsideration, and a motion to amend the counterclaims. Both sides believe that inequitable conduct is a threshold issue and agree that if the motions cannot be resolved by entry of summary judgment, a bench trial is in order. For the reasons given below, I conclude that the motions for summary judgment should be denied because a genuine issue of material fact exists as to the inventor’s intent to deceive the patent office. I address the other pending motions at the end of this opinion.

I. Background

The invention at issue relates to a method of matching the production speed of a paper mill to the demand for paper, a process that ultimately produces paper at lower operating costs. United States Patent No. 6,157,916 begins with the observation that “[cjurrent control systems of the machinery and processes of a facility in the papermaking industry generally run equipment and processes as fast as possible, while maintaining a set level of quality.” (Dkt. #33, Ex. 15 at col. 1, 11. 11-14.) “[Tjhe assumptions that faster is better (if quality is acceptable), underlies the prior art control systems. This is a faulty assumption: faster might actually be less desirable.” Instead of the “as fast as possible” approach, the '916 patent describes a process whereby a papermaking machine operates at a “desired operating speed,” which is “determined by calculating the cost of manufacturing, the manufacturing inflow, and the manufacturing outflow at a plurality of potential operating speeds ... The desired operating speed is determined by calculating a marginal cost of manufacturing, a marginal manufacturing inflow, and a marginal manufacturing outflow ...” (Id. at col. 4, 11. 36^4.) In other words, the patent states that a papermaking machine would operate cheaper if it were run by an integrated system or program that calculated the optimal speed of operation based on a number of economic inputs and outputs.

II. Summary Judgment on Inequitable Conduct

Both sides have moved for summary judgment on the Defendant’s inequitable conduct counterclaims. Summary judgment is appropriate if the moving party establishes that no genuine issues of material fact exist and that it is entitled to judgment as a matter of law. Fed. R. Civ. P. 56. Patent applicants and those substantively involved in the preparation or prosecution of a patent application owe a “duty of candor and good faith” to the PTO. M. Eagles Tool Warehouse, Inc. v. Fisher Tooling Co., Inc., 439 F.3d 1335, 1339 (Fed.Cir.2006) (quoting 37 C.F.R. § 1.56(a) (2004)). Given that duty, a patent applicant must disclose to the PTO all material information he possesses, even if doing so would weaken his application. “Inequitable conduct resides in failure to disclose material information, or submission of false material information, with an intent to deceive, and those two elements, materiality and intent, must be proven by clear and convincing evidence.” Aspex Eyewear Inc. v. Clariti Eyewear, Inc., 605 F.3d 1305, 1315-1316 (Fed.Cir.2010) (quoting Kingsdown Medical Consultants, Ltd. v. Hollister Inc., 863 F.2d 867, 872 (Fed.Cir.1988)). Although summary judgment can be granted if an inequitable conduct claim is doomed as a matter of law, such claims often involve factual disputes; as such, the Federal Circuit “urges caution” in making an inequitable conduct determination at the summary judgment stage. Paragon Podiatry Lab. Inc. v. KLM *798 Labs., Inc., 984 F.2d 1182, 1190 (Fed.Cir.1993).

A. Materiality

As noted above, the first question in assessing an inequitable conduct claim is whether the information not disclosed was material. Information is material if there is a substantial likelihood that it would have been important to a reasonable patent examiner in considering whether to allow the patent. Leviton Mfg. Co., Inc. v. Universal Sec. Instruments, Inc., 606 F.3d 1353, 1358-59 (Fed.Cir.2010). Information “may be material even though it would not invalidate the patent.” Id. IP’s inequitable conduct counterclaims focus on two pieces of information Hoffman did not timely disclose to the PTO, and I address the materiality of that undisclosed information below.

1. Hoffman’s 1980 Publication

IP contends that Hoffman committed inequitable conduct by failing to disclose to the PTO an article he published in 1980. Some background is in order. Just before the '916 patent issued in 2000, Hoffman made a continuing application employing (in IP’s view) claim terms almost identical to those set forth in the '916 patent. Once the '916 patent issued, Latentier then accused the Georgia-Pacific Corporation (not a party here) of infringing the '916 patent. Georgia-Pacific responded by accusing Hoffman of inequitable conduct in failing to disclose his 1980 publication. In response, Hoffman did disclose the publication to the PTO during the prosecution of his continuing application. On December 15, 2006, the PTO examiner rejected the claims in the continuation application on the grounds that they were anticipated by the 1980 article Hoffman had now disclosed. IP argues that because the continuation application contained claims that were nearly identical to the original '916 patent, it is clear that the 1980 article was material not just to the continuing application but to the '916 application as well. Accordingly, Hoffman was under a duty to disclose the article during the '916 application process, and his failure to do so constitutes inequitable conduct.

Latentier does not challenge IP’s view that the claims in the continuation patent were extremely similar to those of the '916 patent. 1 (In fact, the continuation application was initially rejected as an attempt at “double-patenting,” meaning the examiner thought it was simply an effort to extend the life span of the pre-existing '916 patent.) Latentier instead argues that the 1980 article was simply not material to the '916 application because it had nothing to do with control systems and varying the drive speed of papermaking process. (In short, it disagrees with the patent examiner.)
