Sterne Kessler's Patent Office Litigation team has emerged as a dominant force, representing both petitioners and patent owners in a wide range of the USPTO's technology centers — biotech and chemical, electrical, and mechanical. With over 900 proceedings and counting, our results continue to be among the very best.
Sterne Kessler is deeply experienced in all proceedings at the Patent Trial and Appeal Board (PTAB) — inter partes reviews (IPRs), covered business method reviews (CBMs), post grant reviews (PGRs) and derivation proceedings (DERs). We have also handled 400+ reexams on behalf of both patent owners and third party requesters.
Our clients rely on the legal and technical expertise of our multi-disciplinary teams to succeed in Patent Office Litigation proceedings. Our work prosecuting strong, defensible patents informs our work as PTAB litigators.
We also provide strategic guidance on utilizing Patent Office litigation as a part of global IP rights enforcement efforts.
In 2020, Sterne Kessler was named "PTAB Firm of the Year" by Managing Intellectual Property magazine for the third time since the firm received the inaugural award in 2015. The award recognizes Sterne Kessler's superior work representing both petitioners and patent owners before the PTAB.
In addition to practicing at the PTAB, Sterne Kessler remains the thought leader on post grant proceedings — IPRs, CBMs, PGRs, derivation proceedings and reexams. Sterne Kessler published 2019 PTAB Year in Review: Analysis & Trends, which explores the power, resilience, and ever-evolving nature of the U.S. Patent and Trademark Office's Patent Trial and Appeal Board through a series of articles addressing the most significant decisions, updates, and rule changes in 2019. In February 2017, the firm published Patent Office Litigation, Second Edition, providing a fresh and comprehensive exploration of all aspects of the contested patent proceedings before the PTAB.
We also wrote the PTAB Chapter of the ABA/BNA Patent Litigation Strategies Handbook, 4th Edition, 2015 Cumulative Supplement — "Patentability Challenges at the U.S. Patent and Trademark Office."
