Patent opinions from the Eastern District of Texas and the U.S. Court of Appeals for the Federal Circuit

Weekly Digest

IPR / PTAB

Inter partes review is an administrative proceeding before the Patent Trial and Appeal Board in which a petitioner challenges the validity of issued claims on prior art grounds. It runs in parallel with district court litigation and changes it: a district court may stay the case pending the Board's decision, and a final written decision carries estoppel consequences that limit what the petitioner may argue afterwards. The opinions collected here are district court and Federal Circuit decisions touching those proceedings - motions to stay pending review, disputes over the scope of estoppel, and appeals from the Board - rather than the Board's own decisions, which are not part of this collection.
