Post-Vivint Patent Office Treatment of Ex Parte Reexaminations After Non-Instituted IPRs

Given the various ways the Patent Trial and Appeal Board (PTAB) can exercise discretion to deny institution of an inter partes review (IPR) petition (and the corresponding non?appealability of those decisions), ex parte reexamination is becoming an attractive option to challenge patent validity following a decision not to institute. Because a later filed ex parte reexamination is often viewed as a “second bite at the apple,” there were questions as to how the U.S. Patent and Trademark Office (USPTO) should treat these second attempts at invalidating a patent. For IPRs, the PTAB has used several bases for discretionary denial of a later-filed IPR, but those bases were not being applied to follow-on ex parte reexamination requests. However, in In re Vivint, the Federal Circuit held that the USPTO has the authority to discretionarily deny an ex parte reexamination request under 35 U.S.C. § 325(d), i.e., if “the same or substantially the same prior art or arguments previously were presented to the Office.”
