Patent Office Post-Grant Review Proceedings

Related Professionals


Nationally recognized as a top firm for PTAB litigation - IP Stars, 2020

Our Post-Grant Review Proceedings Practice Group regularly represents both petitioners, in challenging patent validity, and patent owners, in defending patents, in trials before the Patent Trial and Appeal Board (PTAB) at the United States Patent and Trademark Office (patent office). PTAB trial proceedings are administered in an expedited manner and serve as an alternative or complement to a U.S. district court or U.S. International Trade Commission (ITC) proceeding where patent validity is at issue.

Our substantial district court and ITC patent trial experience, paired with our technical knowledge across a broad range of technologies and experience handling post-grant matters at the patent office, yields teams with the skills and strategic thinking necessary to successfully navigate inter partes review (IPR), post-grant review (PGR) and covered business method (CBM) review proceedings at the PTAB.

Our comprehensive appellate experience at the Federal Circuit and the U.S. Supreme Court further facilitates our ability to effectively handle the unique procedural and substantive aspects of PTAB trials and related Federal Circuit appeals.

An in-depth knowledge of the laws, rules, and decisions (from both the PTAB and the Federal Circuit) governing PTAB trials, combined with our substantial patent trial experience, allows our attorneys to offer unparalleled counseling to our clients who are contemplating initiating a PTAB trial or who have found themselves facing a PTAB trial as patent owners.
