GlaxoSmithKline v. TEVA
Fed. Cir

Patent and U.S. Food and Drug Administration practices are complex. But these two fields were further complicated by meshing them together in a design intended to both (1) reward drug innovators but then (2) insure that cheaper, generic versions of drugs hit the market quickly after the innovator patents expired. One aspect of this tangled net of highly specialized legal fields was brought to light in the recent case GlaxoSmithKline v. Teva, 2018-1976, 2018-2023 (Fed. Cir., August 15, 2021). This post covers only a small, but still complicated ... Read More ›

In Valeant Pharmaceuticals International, Inc. v. Mylan Pharmaceuticals, Inc., the Federal Circuit reversed the District Court of New Jersey’s grant of summary judgement in favor of Valeant that claim 8 of U.S. Patent 8,552,025 (the ‘025 patent)  owned by Valeant.

In Arthrex, Inc. v. Smith & Nephew, Inc., Arthrocare Corp., No. 2019-2140 (Fed. Cir. October 31, 2019), the Federal Circuit raised Patent Owners’ hopes that inter partes review (IPR) of patents could potentially be constitutionally defective, based on how Patent Trial and Appeal Board (PTAB) judges are appointed. But the court then dashed those hopes by curing the constitutional defect in the statute controlling Administrative Patent Judge (APJ) appointment. For those accused of patent infringement, breathe easy; IPRs survive and can be used to minimize the threat of patents.Read More ›
