Jiaxing Super Lighting Elec. Appliance Co. Ltd. v. CH Lighting Tech. Co., Ltd., No. 23-1715 (Fed. Cir. 2025) – On July 28, 2025, the Federal Circuit issued a decision affirming in part, reversing in part, vacating in part, and remanding the case. Specifically, the Federal Circuit reversed the district court’s grant of JMOL of invalidity in favor of the patent owner, Super Lighting, finding that the district court abused its discretion in excluding CH’s relevant evidence pertaining to establishing the on-sale bar. As a result, the case was remanded for a new trial on validity of the patents.Continue Reading Erroneous Exclusion of On-Sale Bar Evidence: Federal Circuit Revives Invalidity Challenge in Super Lighting v.

Background

Janssen Pharmaceuticals, Inc. and Janssen Pharmaceutica NV (collectively, “Janssen”) market and sell Invega Sustenna, an extended-release intramuscular injectable formulation of paliperidone palmitate used to treat schizophrenia. Janssen sued Teva Pharmaceuticals USA, Inc. (“Teva”) under the Hatch-Waxman Act, 35 U.S.C. § 271(e)(2) in the United States District Court for the District of New Jersey alleging patent infringement relating to U.S. Patent No. 9,439,906 (the ’906 Patent), after Teva filed an Abbreviated New Drug Application (“ANDA”) seeking FDA approval to market a generic version of Invega Sustenna. The ’906 Patent covers specific dosing regimens for Invega Sustenna.

Following two bench trials and a prior Federal Circuit review, the only remaining issue was Teva’s obviousness challenge to the ’906 Patent.Continue Reading Claiming A Range, Watch Out For The Presumption Of Obviousness
