Kai Rajan

Kai Rajan is an intellectual property attorney at Finnegan, Henderson, Farabow, Garrett & Dunner LLP, specializing in patent litigation, patent portfolio development, and post-grant proceedings. His practice encompasses a broad range of technologies, including software, mobile device communication, semiconductors, sensor systems, and various mechanical and electrical innovations. He also has experience with IP issues in emerging areas such as Artificial Intelligence (AI) and additive manufacturing (3D printing), stemming in part from his prior experience as a patent examiner at the USPTO where he handled technologies in healthcare, business methods, and networked sensor systems.

Rajan's litigation practice involves representing both plaintiffs and defendants, though his tracked case appearances and notable successes lean towards defense for operating companies. He acted as counsel for Google LLC in Headwater Research LLC v. Google LLC, a case involving patents related to mobile device communication technology and push notification systems that ultimately settled confidentially. He has also represented Samsung Semiconductor Inc. as a plaintiff in a case concerning semiconductor photodetectors, including CMOS image sensors. Notably, he secured a favorable dismissal for Truist Bank in a patent litigation against USAA involving mobile deposit technologies, following the filing of inter partes review (IPR) petitions. Additionally, he achieved a complete victory for BMW of North America on appeal to the Federal Circuit and successfully invalidated asserted claims through post-grant efforts in a case against Carrum Technologies. He also represented petitioner SharkNinja, successfully cancelling all claims asserted by iRobot at the Patent Trial and Appeal Board (PTAB) in a dispute over robot vacuum cleaner technology.

Rajan possesses extensive experience in PTAB and IPR proceedings, frequently leveraging these post-grant review mechanisms as part of broader patent litigation strategies. He has authored articles on the influence of litigation arguments at the PTAB and trends in IPR and CBM final written decisions. His educational background includes a J.D., cum laude, from Catholic University of America, Columbus School of Law (2013), and a B.S. in Biological Resources Engineering from the University of Maryland (2006). He is admitted to practice in Virginia and before the U.S. District Court for the Eastern District of Texas.
