Post-Grant Proceedings

Kramer Levin ranked #1 for its success rate representing patent owners in IPRs, based on results from the formation of the PTAB in 2012 through April 2022.

  • Kramer Levin’s Post-Grant team leverages extensive patent law knowledge, Patent Trial and Appeal Board (PTAB) experience and litigation skills to achieve winning results for patent holders and patent challengers in PTAB proceedings. We represent clients that include inventors, startup companies, Fortune 100 companies and global brands with technologies that range from pharmaceuticals to high-tech innovations. Our lawyers are leaders in effectively using inter partes review proceedings to help clients secure confirmation of patent claims and invalidate opponents’ patents.

    As litigators with a long history of successful trial and appellate work, we are especially skilled at creating engaging, compelling and convincing arguments that have resulted in unprecedented wins for our clients both before the PTAB and in parallel proceedings in district court throughout the United States. Our team also helps clients strengthen their patents and challenge patents of others using a variety of mechanisms, including inter partes reviews, post-grant reviews, reviews of covered business method, and ex parte re-examinations.
