Plaintiff Parkervision, Inc. filed a patent infringement action against Qualcomm. Qualcomm answered the complaint and alleged an affirmative defense of inequitable conduct and a counterclaim that included a claim for inequitable conduct. Parkervision moved to strike the affirmative defense and the counterclaims pertaining to inequitable conduct, among other defenses and claims.
As explained by the district court, “Qualcomm counterclaims that ParkerVision’s ‘551 patent is unenforceable due to ParkerVision’s inequitable conduct and that the other five ParkerVision patents — ‘518, ‘371, ‘734, ‘342, and ‘845 — are also unenforceable because they stem from the ‘551 patent. (Doc. No. 91, ¶¶ 69-116.) All six of the inequitable conduct counterclaims thus rest on the factual allegations regarding the ‘551 patent. Specifically, Qualcomm sets forth three theories of inequitable conduct, alleging that Michael Q. Lee, the ‘551 patent’s prosecuting attorney, and David F. Sorrells, an inventor: (1) “buried” the Patent and Trademark Office (“PTO”) with references; (2) belatedly disclosed a material reference to the PTO; and (3) materially misrepresented four references to the PTO. Qualcomm urges the Court to consider the alleged inequitable conduct cumulatively, as a “course of deliberate egregious misconduct.” (Id. ¶ 35.)”
