On August 29, 2022, Gish PLLC filed two petitions for inter partes review in the Patent Trial and Appeal Board on behalf of Dayus Register & Grille, Inc. The first petition challenges U.S. Patent No. 9,765,988, while the second petition challenges U.S. Patent No. 10,871,305. Each petition asserts multiples grounds for unpatentability based on prior art references that were not cited during prosecution of the foregoing patents.
Patent Owner INV Holdings Inc. and licensee Arch Grilleworks, Inc. have asserted those patents in an infringement action that is currently pending in the U.S. District Court for the Eastern District of New York. Gish PLLC represents Dayus in that district court action, which is Case No. 2:21-cv-5107-GRB-ST.
The PTAB proceedings are Case Nos. IPR2022-001472 and IPR2022-01475, respectively.
