Isaac Phillip Rabicoff

Isaac P. Rabicoff is a patent litigator and the founder of Rabicoff Law LLC. His practice focuses exclusively on representing plaintiffs in patent infringement litigation, as reflected in his record as lead counsel for plaintiffs in all eight of his tracked cases. The entities he has recently represented, such as ContentNexus LLC, Authentixx LLC, and Modulus Systems LLC, are consistent with a practice centered on patent assertion. His firm biography states it has led licensing and litigation campaigns against major technology companies, including Amazon, Apple, Google, and Microsoft.

Mr. Rabicoff's practice is national in scope, with litigation experience in popular patent venues like the Eastern District of Texas and the District of Delaware. He is also a registered patent attorney who represents clients in post-grant proceedings before the Patent Trial and Appeal Board (PTAB). His firm notes successes in defeating the institution of inter partes review (IPR) and covered business method (CBM) review petitions. He has also argued before the U.S. Court of Appeals for the Federal Circuit and has authored an amicus brief to that court.

In 2022, Mr. Rabicoff received a public reprimand from the Virginia State Bar related to violations of California's professional rules of conduct in a patent case in the Northern District of California. The disciplinary action followed a federal court's 2020 order sanctioning him for conduct that included filing amended complaints without leave of court and failing to seek pro hac vice admission in numerous cases where he appeared as lead counsel.

Mr. Rabicoff earned his J.D. from Loyola University Chicago and a Bachelor of Science in Physics from the University of Kansas. He is admitted to the Illinois and Virginia bars.
