As part of our Patents practice, we provide post grant review (PGR) services.
Patent Post-Grant Review (PGR) is one of the newest proceedings available in the US Patent & Trademark Office (USPTO). PGR provides a means to challenge an issued patent. However, a PRG request must be filed within nine months of issuance. Therefore, time is of the essence to challenge a patent through Post-Grant Review.
Combining experience in patent prosecution and litigation, we serve both patent holders as well as challengers in Patent Post-Grant Review.
Post-Grant Review of Patents
PGR provides a broader means to attack the validity of a patent as compared to inter partes review and ex parte reexamination. A third party may challenge a patent through a Post-Grant Review based on any of the following grounds:
Invalidity under 35 U.S.C. § 282(b)(2) or (3)
Patent subject matter eligibility or utility under 35 U.S.C. § 101
Novelty under 35 U.S.C. § 102
Obviousness under 35 U.S.C. § 103
Enablement, written description, and definiteness under 35 U.S.C. § 112.
Process for Patent Post-Grant Review
Post-Grant Review is generally only available to challenge patents having an effective filing date after March 16, 2013. However, covered business method (CBM) patents are eligible for Post-Grant Review regardless of their filing date. Patent PRG challenges are time-limited requiring filing within nine months of patent issue date.
