Patent Trial and Appeal Board
Our lawyers have been pioneering trial practice at the Patent Trial and Appeal Board (PTAB) since its first minutes of operation on September 16, 2012, filing multiple petitions early that morning, and have appeared continuously before the PTAB in more than 190 high-stakes Inter Partes Reviews (IPRs), Post Grant Reviews (PGRs), and Covered Business Method (CBM) reviews on behalf of both petitioners and patent owners. We also have extensive experience in Ex Parte Reexaminations. Exemplary matters include representing:
