Post-Grant Proceedings PTAB Powerhouse

Post-grant proceedings provide faster, more cost-effective ways to challenge issued patents before initiating or in parallel with court proceedings. Since the enactment of the America Invents Act, our registered patent attorneys and litigators have successfully handled hundreds of post-grant proceedings — inter partes reviews (IPR), covered business method (CBM) reviews, post-grant reviews (PGR), ex parte reexaminations, and supplemental examinations — before the Patent Trial and Appeal Board (PTAB) for both petitioners challenging patents and patent owners. Our Post-Grant Proceedings Team draws from our more than 200 registered patent attorneys with specializations across all technologies, and includes patent litigators with extensive experience in post-grant and federal court proceedings. Our success on both sides of the table has earned us national recognition as a top law firm in total IPR institutions for petitioners and as a top firm in blocking institutions of IPRs for patent owners. We also handle similar European opposition proceedings, IPRs involving patents concurrently in litigation, and cross-over patent litigation strategy.
