PTAB

AIA trial proceedings.

Inter Partes Review, Post-Grant Review, and Covered Business Method proceedings at the USPTO Patent Trial and Appeal Board. Refreshed every six hours from the USPTO decisions feed, so outcomes track through institution, settlement, and the final written decision — where we read the claim-level result (invalidated vs sustained) straight from the decision. Each proceeding links to the patent it’s challenging — when we have a dossier on file, the row jumps to it directly.
