Ian Neville Feinberg

I'll research this attorney's background and verify the tracked case.

Let me dig into the tracked case and additional background.

Let me check a couple more items — a possible Federal Circuit result and PTAB appearances.

Ian Neville Feinberg — Feinberg Day (Menlo Park / Burlingame, CA)

Focus areas. Feinberg's practice centers on complex IP litigation with a patent emphasis, spanning semiconductors and memory technologies, enterprise software, networking/security, solar, and video-on-demand/consumer electronics. Firm-supplied case listings and contemporaneous coverage show work across the electronics and software stack — RAID storage, embedded memory, semiconductor process equipment, and software/font copyright — alongside parallel trademark, trade-secret, and antitrust/tying matters. Notable examples include Cadence Design Systems v. Berkeley Design Automation (defense of Berkeley Design Automation), The Solaria Corp. v. Canadian Solar (tiled solar-cell laser processing), Broadband iTV v. DISH Network (VOD patents), and Adobe Systems v. Southern Software (copyright in font software; summary judgment for his client plus a $2 million settlement and injunction).

Side preference. The tracked data is thin — a single appearance, on the plaintiff side, as lead counsel in Intellectual Ventures II LLC v. Commerce Bancshares, Inc. (W.D. Mo.). That is consistent with his most visible recent docket: substantial representation of Intellectual Ventures entities as plaintiff in patent-enforcement actions (including the 2011 IV I/IV II suits against Motorola Mobility) and of other plaintiffs such as KGR IP and Broadband iTV. Historically, however, his bios and dockets reflect a genuinely mixed practice — he defended operating companies such as Berkeley Design Automation, Turner Designs, Toshiba-facing matters, Honda, and nVision/BioCardia in addition to prosecuting claims for patent owners. On the record available, he is best described as a both-sides IP litigator whose recent publicly reported work skews toward patent-owner/plaintiff enforcement rather than a pure defense practice.

Firm context. He co-founded Feinberg Day Alberti & Thompson LLP in 2011 with six litigators from DLA Piper, after which the firm's name evolved (Feinberg Day Kramer Alberti Lim Tonkovich & Belloli LLP; now Feinberg Day LLP). Before that he spent 2003–2011 at Mayer Brown, where he led the global intellectual property practice, and roughly two decades at Ware & Freidenrich / Gray Cary Ware & Freidenrich (a DLA Piper predecessor), most of it as partner. He began at Heller Ehrman (1979–81).

Notable outcomes, PTAB, and credentials. The tracked IV v. Commerce Bancshares matter went badly for his client: the district court case closed in 2014 while the defendant banks pursued parallel IPRs (IPR2014-00724/-00786/-00801, plus CBM proceedings) that invalidated the asserted IV patents, and the Federal Circuit affirmed in March 2017 (Nos. 2016-1519 et al.). He appears as counsel of record in Patent Office trials on both sides — as patent-owner counsel in the IV IPRs, for petitioners in covered-business-method proceedings, and in the Solaria/Canadian Solar IPRs (IPR2021-00095, -00659) — so PTAB experience is real, though the available record does not establish a dedicated IPR practice. One reported setback: in 2012 Judge William Alsup disqualified Feinberg Day from Talon Research v. Toshiba over the firm's prior confidential representation of Toshiba in NAND flash matters. Education and bar: Stanford University (A.B. 1976) and Stanford Law School (J.D. 1979); admitted in California in 1979 (SBN 88324), with admissions to the Ninth Circuit, D. Arizona, and all four California district courts.
