Kayvan B. Noroozi

Specialty / focus areas. Kayvan B. Noroozi is a patent trial lawyer whose practice is concentrated in high-stakes electrical- and software-centric disputes: cellular/wireless telecommunications, speech recognition, graphical user interfaces, audio/DSP, semiconductor systems-on-a-chip, and standard-essential patent/FRAND issues. His tracked matters involve speech-recognition patents asserted against Apple's Siri and Amazon's Alexa, Dolby audio-patent challenges, and, per his own sworn practice descriptions, technologies ranging from Power over Ethernet to mobile location and computer search/indexing. His co-authored Berkeley Technology Law Journal article with Prof. Richard Epstein on FRAND "patent holdout" reflects a SEP/FRAND policy focus. No meaningful pharma or mechanical practice appears.

Side preference. The case list is nominally 4 plaintiff / 2 defendant, but in substance Noroozi is a patent-owner-side lawyer. Both "defendant" entries are defensive patent-owner roles — Zentian Ltd. as appellee against Apple's Federal Circuit IPR appeal, and Dolby Laboratories Licensing Corp. defending its patent in Unified Patents' IPR. He consistently represents patent owners and licensors (Zentian, Dolby, and historically Core Wireless and Realtime Data) against large operating companies and IPR petitioners such as Apple, Amazon, LG, Google, and Unified Patents — asserting patents, defending them in IPRs, and taking resulting appeals. He has described his firm as historically representing "more patent owners."

Firm context. Noroozi is founding partner of Noroozi PC in Los Angeles (founded 2014), a boutique commercial IP litigation firm. He previously practiced at Dovel & Luner LLP (Santa Monica) and Irell & Manella, and began his career as a law clerk to Judge Jerry E. Smith of the U.S. Court of Appeals for the Fifth Circuit.

Notable cases / PTAB / bar. Most prominent tracked matters: Dolby Laboratories Licensing Corp. v. Unified Patents, LLC (Fed. Cir. No. 23-2110; Supreme Court cert. petition No. 25-1011), where he leads Dolby's challenge to the PTAB's refusal to force Unified to name real parties in interest — a precedent-setting IPR-governance dispute; and the Zentian Ltd. v. Apple Inc. / Amazon campaign (including Fed. Cir. No. 24-2207, pending), in which the PTAB upheld Zentian's speech-recognition claims against Apple/Amazon IPRs. Web-verified highlights from his broader record include the winning Federal Circuit brief in Core Wireless Licensing S.A.R.L. v. LG Electronics, 880 F.3d 1356 (Fed. Cir. 2018), upholding § 101 eligibility of GUI patents after a top-ten Texas verdict, and lead ITC trial counsel in Certain LED Products (337-TA-1168). He is deeply experienced before the PTAB, reporting more than 70 IPR proceedings, predominantly defending patent owners. Education/bar: University of Chicago Law School (2009); California bar (2010); admitted E.D. Tex. and N.D. Cal. (per USPTO pro hac vice declarations).
