Kassandra M. Officer

Kassandra M. Officer is a prominent patent litigation attorney with a focus on complex, high-stakes patent and trade secret disputes. Her practice encompasses a diverse range of technologies, with particular emphasis on chemicals, pharmaceuticals, medical devices, and agricultural products. She is experienced in litigations arising under the Hatch-Waxman Act and the Biologics Price Competition and Innovation Act (BPCIA), representing pharmaceutical patent holders.

Ms. Officer primarily operates as outside counsel at Finnegan, Henderson, Farabow, Garrett & Dunner, LLP, where she is a partner. While her experience includes representing both plaintiffs and defendants in trade secret misappropriation actions and agricultural patent disputes, her tracked appearances indicate a role representing companies like Google LLC in challenging patent assertions.

Her notable experience includes successfully representing DuPont and ADM in a Federal Circuit appeal from an inter partes review (IPR) proceeding, which resulted in the reversal of the Patent Trial and Appeal Board's (PTAB) decision and the invalidation of all challenged claims of Synvina's patent related to 2,5-furan dicarboxylic acid production. She has also appeared as counsel for Google LLC in an IPR against Headwater Research LLC. Ms. Officer is particularly active in post-grant proceedings before the PTAB, representing clients in IPRs and ex parte reexaminations. Her PTAB practice involves developing validity positions, drafting submissions, preparing and defending expert witnesses, and arguing before the Board. She also maintains an active patent prosecution and counseling practice, specializing in chemical, pharmaceutical, and veterinary drug products.

Ms. Officer is admitted to practice in the District of Columbia and Massachusetts, and before the U.S. Patent and Trademark Office and the U.S. Court of Appeals for the Federal Circuit. She earned her J.D., cum laude, from Indiana University Maurer School of Law in 2014, and holds a B.S. in Chemical and Biomolecular Engineering from The Ohio State University.
