USPTO Trials and Post-Grant Proceedings

USPTO Trials and Post-Grant Proceedings

We are one of the few firms well-positioned to handle the unique and often complicated aspects of inter partes patent cases in the United States Patent and Trademark Office (USPTO).

Our dedicated team of attorneys and extensive experience allow us to successfully manage and resolve both patent interference and reexamination proceedings—from initial review by the USPTO Patent Trial and Appeal Board through final hearing by the US Court of Appeals for the Federal Circuit. Indeed, our USPTO-registered attorneys are involved in all aspects of inter partes proceedings. We regularly develop strategies that help our clients both invoke and/or avoid declarations of interference, using our vitally important litigation skills and deep technical understanding to proactively establish a strong position that, in many cases, prevents long and costly opposition.

Our expertise spans a wide range of technical disciplines, including molecular biology, genetics, semiconductor processing, computer software, and medical devices. We also stand ready to help our clients leverage the broad patent law changes introduced by the America Invents Act—including the replacement of traditional inter partes reexaminations with new proceedings that more closely resemble litigation. Several of our attorneys served on USPTO committees that developed rules for these proceedings, giving us an intimate knowledge of the changes, and positioning us to provide the highest level of representation in the USPTO's new proceedings.
