Post-Grant Practice

Setting McAndrews above most firms in the nation, we have decades of trial experience at the Patent Trial and Appeal Board.  It is therefore no surprise that McAndrews has one of the most active dockets of AIA trial proceedings of any law firm in the United States.  Indeed, as of May 2018, we have represented our clients in nearly 150 inter partes, post grant review, and covered business method patent review proceedings — on behalf of both petitioners and patent owners.  The foundation of our expertise in post-grant trials is our more than three decades of representing clients in hundreds of patent interferences, inter partes reexaminations, and ex parte reexaminations.

McAndrews attorneys have from the earliest days of the AIA been at the forefront of post-grant practice.  Our attorneys have held leadership positions on post-grant practice committees of the American Bar Association, American Intellectual Property Law Association, and Intellectual Property Owners Association.  For instance, one of our attorneys served on the IPO/ABA/AIPLA Expert Committee on Regulations for Conducting New PGR/IPR Procedures, which was responsible for reviewing and proposing the first regulations implementing the post-grant provisions of the America Invents Act, as well as on the AIPLA Special Task Force on AIA Rulemaking (Chair of the post-grant issues team).
