Firm overview
As of May 2026, Fenwick & West LLP is a prominent BigLaw firm renowned for its focus on the technology and life sciences sectors. Founded in Silicon Valley in 1972, the firm has grown to include over 500 attorneys across offices in major U.S. technology hubs, including Silicon Valley, San Francisco, Seattle, New York, Santa Monica, Boston, and Washington, DC. Fenwick ranked 69th on the AmLaw 100 list in 2025 by revenue, and its intellectual property practice is consistently recognized by industry publications like Chambers and Partners.
The firm's patent litigation practice is deeply rooted in high-technology and life sciences industries. Fenwick litigators handle complex disputes involving software, computer hardware, networking, semiconductors, artificial intelligence, and medical devices. Their client roster includes a mix of startups and established global enterprises. The firm's website states it represents both patent holders and alleged infringers. However, the provided case data shows a defense-side appearance for LG Electronics in Multimedia Technologies Pte Ltd v. LG Electronics Inc, and a 2023 Patexia report named Fenwick the "Best Performing Law Firm (Representing Defendants)".
Fenwick has secured numerous public victories for its clients. The firm recently obtained a complete defense verdict for Amazon and its subsidiary eero in a wireless mesh networking patent case in the Western District of Texas. In another matter for Amazon, a jury in the Eastern District of Texas found that Alexa-powered devices did not infringe and that the asserted patents were invalid. The firm also has a significant appellate practice, having been counsel on over 225 appeals in the last decade, with a particular focus on patent cases at the Federal Circuit.
The firm maintains a robust practice before the Patent Trial and Appeal Board (PTAB), having handled nearly 200 inter partes review (IPR) and post-grant review (PGR) proceedings for both petitioners and patent owners. A recent success includes a 2026 Federal Circuit win for client Digital Turbine, affirming a PTAB decision that allowed the amendment of a patent during a post-grant review. Key partners in the patent litigation practice include Michael J. Sacksteder, who is listed as lead counsel for LG in the provided data and has a track record of trial success in major patent venues, and Jedediah Wakefield, the chair of the firm's litigation practice.
