PTAB Ex Parte Patent Proceedings

Given our extensive experience and track record of proven success, we are uniquely qualified to assist clients in various ex parte proceedings before the U.S. Patent and Trademark Office (USPTO).

By applying our diverse legal and technical backgrounds, we provide strategic counseling and aggressive litigation services that advance both our clients’ offensive and defensive goals—always with a keen understanding of how ex parte proceedings are intertwined with various litigation, enforcement, and licensing strategies. We have successfully assisted a wide variety of clients in numerous industries in reexamination, reissue, and supplemental examination proceedings to strengthen a patent’s validity prior to litigation or to preempt an attack on a patent.

Defensively, we use ex parte reexaminations to defer litigation costs, challenging a patent’s validity, and/or gain leverage during licensing negotiations. We wisely use ex parte proceedings to quickly and cost-effectively advance our clients’ strategic interests.
