Post grant proceedings cover patent office trials such as Inter Partes Review (IPR), Post Grant Review (PGR), and Business Method Review (CBM).

Other post grant procedures:

  • Reexamination 
  • Supplemental Examination 
  • Reissue Applications 
  • Certificates of Correction 

BSKB was one of the first firms to have a practice group dedicated to patent reexaminations, patent reissues and other types of post-grant patent review proceedings before the U.S. Patent and Trademark Office (USPTO). Our experience in these specialties allows us to offer clients powerful alternatives that can be utilized in addition to or instead of patent litigation. Post grant proceedings involve aspects of patent litigation and patent prosecution that require highly experienced counsel who are skilled in navigating and conducting these proceedings before the USPTO as well as patent litigation in the courts. The creation of additional post grant proceedings as part of the America Invents Act (AIA) has allowed BSKB’s post grant practice group to utilize its extensive expertise in these adversarial challenges to patentability.

BSKB is pleased to offer a separate website on post-grant review practice, Here you will find up-to-date information about post-grant issues and recent cases. BSKB is also pleased to offer a post grant proceeding-specific training seminar, the Post Grant Bootcamp, to educate participants on post grant issues.

As with our patent prosecution practice and patent litigation practice, our post-grant review practice covers every aspect of science, technology and engineering. Our post grant patent team is comprised of skilled intellectual property attorneys and other experts who have the background required for understanding complex, multi-disciplinary technologies and arguing before senior level Patent CRU Examiners, the Patent Trial and Appeal Board (PTAB), and the Court of Appeals for the Federal Circuit (CAFC). Specifically, since their creation in 2012, BSKB has represented clients in numerous inter partes reviews and covered business method proceedings. A representative list is below.

BSKB’s post grant patent law practice leverages strategic insight of the latest patent law trends, comprehensive understanding of technical issues and in-depth knowledge of USPTO proceedings to strengthen patents, challenge patentability, and successfully license and enforce patent rights on behalf of our clients.
