In Parallax Grp. Int’l, LLC v. Incstores LLC, No. 8-16-cv-00929, 2022 U.S. Dist. LEXIS 157921 (C.D. Cal., August 16, 2022), the district court judge granted-in-part Parallax’s Motion to Dismiss All Claims and Counterclaims and for Entry of Final Judgment but denied the motion with respect to the inequitable conduct counterclaims, allowing that issue to go forward in the context of an anticipated fees motion.
Parallax sued Incstores for infringement of U.S. Patent Nos. 9,289,085 ("the '085 Patent"), D532,238 ("the D238 Patent"), and D543,764 ("the D764 Patent"), which relate to interlocking foam floor mats. Defendant Incstores filed counterclaims for noninfringement, invalidity, unenforceability based on inequitable conduct (the “inequitable conduct counterclaims”), and an exceptional case finding under 35 U.S.C. § 285 for an award of reasonable attorney’s fees. Parallax, at *1-2.
During the course of this case, Parallax withdrew its infringement claims concerning the D238 Patent (which had recently been cancelled in a reexamination). Id. at *1. The D764 patent was found invalid by the Court. Id. And the ‘085 patent was held unpatentable by the PTAB in a reexamination, which was affirmed in the Federal Circuit. Id. at *2. Since there was nothing left for Parallax’s case, the parties stipulated to dismiss Parallax’s infringement claims with prejudice, and Incstores’ noninfringement and invalidity counterclaims without prejudice as moot. Incstores could seek attorney’s fees via motion. Id. at *3.
The only issue left was whether Incstores is entitled to pursue its inequitable conduct counterclaims. Id. at *3-4. Not only would a finding of inequitable conduct be helpful for Incstores to show an exceptional case, but Incstores pointed out that there are related patents not at issue in this case which Parallax could still try to enforce, and which may be implicated by the inequitable conduct. Id. at *4.
