Isaac Rabicoff

Isaac Rabicoff is the founder of Rabicoff Law LLC, a firm focused on intellectual property litigation. His practice primarily involves representing patent holders in infringement litigation, and he has experience across a variety of technology sectors, including data storage systems, image processing, and other software and electronics-related fields. The firm's website states it has led licensing and enforcement campaigns against numerous high-profile technology companies, including Amazon, Apple, Google, and Samsung.

Consistent with the provided case list showing him exclusively as plaintiff's counsel, Mr. Rabicoff's practice concentrates on asserting patents on behalf of patent owners and non-practicing entities (NPEs). His firm, Rabicoff Law, was named by Lex Machina as one of the most active patent litigation firms in 2017. News reports from 2025 indicate the firm represents several high-volume patent filing entities. One of his clients, Cedar Lane Technologies Inc., has sued hundreds of defendants, with a litigation model that appears to focus on achieving early, modest settlements rather than proceeding to trial.

Mr. Rabicoff is a registered patent attorney with experience in post-grant proceedings before the Patent Trial and Appeal Board (PTAB). He has represented patent owners in inter partes review (IPR) and covered business method (CBM) review proceedings, and his firm notes success in defeating the institution of such petitions. He has also argued before the U.S. Court of Appeals for the Federal Circuit.

Mr. Rabicoff earned his J.D. from Loyola University Chicago and a Bachelor of Physics from the University of Kansas. He is admitted to practice in Illinois and Virginia, and before the U.S. Patent and Trademark Office. In November 2020, while representing Cedar Lane Technologies, he was sanctioned by the U.S. District Court for the Northern District of California for frivolous arguments and referred to the court's professional conduct committee for filing numerous lawsuits in the district without being a member of its bar.
