Baker & Hostetler

Baker & Hostetler LLP is a prominent national law firm, headquartered in Cleveland, Ohio, with 18 offices strategically located across the United States, including major legal markets such as New York, Washington D.C., Los Angeles, Chicago, and Houston. As one of the largest firms in the U.S., it operates with over 1,000 lawyers and was ranked #57 in the AmLaw 200 in 2024, solidifying its status as a BigLaw firm.

The firm's intellectual property litigation practice is characterized by a broad technical bench, handling complex matters across diverse technology sectors. Its expertise spans "hi-tech" areas like software, artificial intelligence (AI), robotics, battery, and unmanned aerial vehicle (UAV) technology, as well as pharmaceuticals, medical devices, and other electrical, mechanical, chemical, and biological arts. Based on tracked cases, the firm primarily represents defendants, focusing on defending operating companies against allegations of patent infringement. All three tracked appearances for the firm were on the defendant side.

Baker & Hostetler has achieved notable outcomes for its clients. In Alpha Modus Corp. v. Mood Media, LLC, the firm secured a defendant win with the case dismissed with prejudice in the Western District of Texas in February 2026, involving patents related to IoT sensor technology, digital signage, and data-driven retail. The firm also represented defendants in Realtime Data LLC v. Array Networks Inc. et al. and Realtime Data LLC v. Reduxio Systems, Inc. et al., both involving patents for data compression and digital data transmission. The Federal Circuit affirmed the dismissal of Realtime Data LLC v. Array Networks Inc. et al. for invalidity under 35 U.S.C. § 101 in August 2023, agreeing that the claims were directed to an abstract idea. In Realtime Data LLC v. Reduxio Systems, Inc. et al., the Federal Circuit vacated and remanded a district court's bench ruling of patent ineligibility, citing insufficient findings and reasoning in October 2020.

The firm maintains a robust Patent Trial and Appeal Board (PTAB) practice, having handled over 100 inter partes review (IPR) and post-grant review (PGR) proceedings since the America Invents Act (AIA) implementation in 2012. This includes successfully defeating IPRs against semiconductor manufacturing patents and invalidating numerous claims for clients like Microsoft. Key partners in the patent litigation group include Jeffrey J. Lyons, recognized in Delaware Today magazine as a "Top Lawyer" for his experience in over 40 patent litigation matters across various technologies, and Kevin Kirsch, noted by Chambers USA for his extensive trial practice in life sciences and hi-tech. Jason Hoffman, based in Washington D.C., is also a prominent litigator with significant jury trial and Federal Circuit victories.
