Firm overview

Norton Rose Fulbright US LLP operates as a significant component of a global law firm, headquartered in London, with a broad international footprint encompassing over 50 cities across six continents. In the United States, the firm maintains extensive operations with offices in major cities including Houston, New York, Dallas, Los Angeles, Chicago, and Washington D.C., among others. As a prominent BigLaw firm, Norton Rose Fulbright was ranked #19 in the AmLaw 100 in 2026 and #57 in the Vault Law 100 for 2026, reflecting its substantial size with over 3,000 lawyers globally.

The firm's intellectual property litigation practice specializes in a diverse array of technology areas. Its experience spans complex fields such as semiconductors, microprocessors, telecommunications (including passive optical networks), software, and life sciences, including pharmaceutical and biotechnology patent disputes. Norton Rose Fulbright handles a wide range of IP matters, encompassing patent, copyright, trademark, trade secret, and trade dress issues. The practice notably emphasizes a trial-ready approach, managing cases across both district courts and the Patent Trial and Appeal Board (PTAB).

Norton Rose Fulbright predominantly represents defendants in patent litigation, with five of its seven tracked appearances being on the defense side, compared to two for plaintiffs. This aligns with its stated practice of defending operating companies, including major players like Volkswagen, Intel, AT&T, and Olaplex. Notable cases include representing AT&T in a patent infringement action by SPADA Innovations, Inc., and defending Intel and ON Semiconductor in cases brought by Greenthread, LLC, where a stay was secured pending inter partes review (IPR) proceedings at the PTAB, leading to the administrative closure of the district court litigation without a verdict or damages. The firm also defended Olaplex Inc. in an IPR initiated by Unified Patents [cite: internal data].

The firm maintains an active PTAB practice, regularly handling post-grant proceedings. Its team manages IPRs and other PTAB challenges, with partners like Daniel Leventhal and Stephanie DeBrow listed as counsel in IPR filings. This capability is critical for clients seeking to challenge or defend patent validity outside of district court litigation.

Key partners leading the firm's IP litigation efforts include Daniel Leventhal, who serves as Co-head of the US IP Disputes Group and is recognized as a high-tech patent litigator [cite: internal data, 7, 20]. Brett C. Govett is a seasoned trial lawyer with four tracked appearances and a focus on cases in the Eastern District of Texas, and is a member of the American Board of Trial Advocates [cite: internal data, 7, 18, 20, 28]. Tim Kenny co-heads the US IP Disputes Group and is the firm's US Head of Intellectual Property, while Richard Zembek serves as the firm's Global Head of Technology and is a well-regarded IP litigator.
