GFI, Inc. (formerly known as The Gentry Gallery, Inc.) (“GFI”) appeals the judgments of the United States District Court for the Northern District of Mississippi (1) holding its United States Patent No. 5,064,244 (“'244 patent”) unenforceable for inequitable conduct, GFI, Inc. v. Franklin Corp.,
Background
GFI filed an application on January 3, 1991 for a patent on a sectional sofa in which a pair of reclining seats, on the same side of a wedge, is separated by a fixed console, which contains the control means for the reclining seats. GFI then filed a Petition to Make Special to expedite its consideration. After an initial rejection, GFI met with the examiner on June 12, 1991. The application issued as the '244 patent on November 12,1991.
During the prosecution of the '244 patent, GFI entered discussions with Walter Durling, a furniture designer from Mississippi who designed and built a loveseat-like unit consisting of two recliners joined by a middle console. Durling filed a patent application on this design two months before the '244 patent application was filed. The discussions between GFI and Durling centered on extracting information from Durling regarding his conception and reduction to practice of the design. The application did not specify the location of the recliner controls, but Sproule, the named inventor of the '244 patent, saw a model of the Durling furniture in late October or early November of 1990 that had console-mounted controls. Durling offered to exchange his conception information for similar information about the conception and reduction to practice of the invention underlying the '244 patent; GFI refused. In 1997, GFI brought suit for patent infringement against Franklin, Astro, Park-hill, and Washington (collectively “Franklin”). The defenses of inequitable conduct, obviousness, laches, equitable estoppel, and patent misuse were tried to the court in a non-jury trial.
Discussion
First, we address GFI’s claim that the district court forced it to disclose privileged information to Franklin. We apply regional circuit law to procedural questions that are not themselves substantive patent law issues so long as they do not (1) pertain to patent law, Flex-Foot, Inc. v. CRP, Inc.,
The Fifth Circuit reviews a district court’s ruling on waiver of attorney-client privilege for clear error as a question of fact, and reviews conclusions of law, de novo. United States v. Robinson,
Franklin claims that GFI waived the privilege when its patent attorney testified in an earlier trial, Gentry Gallery, Inc. v. Berkline Corp.,
To prevail on its defense of inequitable conduct, Franklin must prove by clear and convincing evidence that GFI withheld material information from the PTO, and the information was withheld with intent to deceive the PTO. Purdue Pharma L.P. v. Boehringer Ingelheim GMBH,
Inequitable conduct entails a two-step analysis: first, a determination of whether the withheld reference meets a threshold level of materiality and intent to mislead, and second, a weighing of the materiality and intent in light of all the circumstances to determine whether the applicant’s conduct is so culpable that the patent should be unenforceable. Baxter Int'l Inc. v. McGaw, Inc.,
The district court properly found the Durling references material because they contained the elements of two recliners joined by a middle console, albeit in a loveseat and not a sectional, and had console-mounted controls on the model viewed by Sproule. GFI argues that Durling cannot be material because it is not prior art. That is not the law, and, even if it were, the very essence of the discussions between GFI and Durling were motivated by an effort to determine priority of invention between the '244 patent and Durling’s patent application. The district court made no finding as to priority and we will not make that determination in the first instance on appeal. In any case, it was incumbent on GFI to disclose the potential priority conflict to the examiner and not to unilaterally make a determination that Durling was not prior art. LaBounty Mfg., Inc. v. United States Int’l Trade Comm’n,
As we have noted before, the facts in inequitable conduct cases rarely include direct evidence of admitted deceitful conduct. Molins PLC v. Textron, Inc.,
The strongest case for deceptive intent are the Durling references. It is undisputed that GFI was aware of the references. GFI possessed a copy of the Durling patent application (sent to it by
No single factor or combination of factors can be said always to require an inference of intent to mislead. Yet 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 “subjective good faith” sufficient to prevent the drawing of an inference of intent to mislead. Critikon, Inc. v. Becton Dickinson Vascular Access, Inc.,
Conclusion
Accordingly, the judgments of the United States District Court for the Northern District of Mississippi are affirmed.
AFFIRMED.
