Eugene T. Bunsow

Name/disambiguation note: Public sources — firm profiles, Law.com/ABA Journal coverage, and federal court filings — document Henry C. Bunsow, the founding name partner at Bunsow De Mory, and no attorney practicing under the name "Eugene T. Bunsow." The tracked docket entry (one defendant-side appearance as lead counsel, Bunsow De Mory) is consistent with the Bunsow De Mory practice, so the summary below describes that record while flagging that the first name in the source data could not be corroborated. Facts below are attributed to the named sources; where something could not be verified, it is noted.

Focus areas. The Bunsow De Mory practice is a technology-heavy IP litigation boutique handling patent infringement and trade secret cases in federal district courts and the ITC, plus PTAB proceedings. Reported technical coverage is broad and engineering-oriented: electrical and computer engineering, semiconductors, data storage and deduplication/cloud backup (Delphix Corp. v. Actifio, per a USPTO petition record), optical communications and modulation techniques (Ramot at Tel Aviv University v. Cisco Systems), mobile/wireless power-control technology (TOT Power Control v. Apple), magnetic storage media (Lambeth Magnetic Structures v. Seagate), and life-sciences/antibody work (the Genentech–Chiron dispute referenced in Centocor v. Genentech filings), alongside consumer-products matters such as the Acushnet (Titleist) golf ball litigation.

Side preference. The tracked data show a single appearance, on the defendant side, as lead counsel for a Bunsow De Mory client (0 plaintiff / 1 defendant). That is a thin sample and runs opposite to the firm's stated orientation: Bunsow De Mory describes itself, and is ranked by Benchmark Litigation and IAM, as a predominantly plaintiff-side enforcement shop representing patent owners, universities, and technology companies. No conclusion about this individual's side preference should be drawn from a one-case docket.

Firm context. Current affiliation per the docket is Bunsow De Mory LLP (Redwood City, California, with an Alexandria, Virginia office), where the Bunsow name is that of the founding family of the firm. Public reporting on the name partner's career trajectory: Townsend and Townsend and Crew (roughly 15 years), Brobeck, Phleger & Harrison (about two years), Keker & Van Nest (1994–2003), then Howrey (San Francisco office, where he served as vice chairman), and in 2011 Dewey & LeBoeuf, where he co-chaired the firm-wide IP litigation practice before the group formed Bunsow, De Mory, Smith & Allison (later Bunsow De Mory).

Notable matters and results. Reported outcomes include Acushnet Co. v. Callaway Golf (D. Del.) — after losing the 2007 trial and an injunction against the Pro V1, the team won a retrial in 2010 with a jury finding Callaway's golf ball claims invalid for anticipation and obviousness; the Genentech antibody/Herceptin dispute against Chiron (defense verdict, with the Federal Circuit appeal noted in later recusal briefing); and Bridgelux v. Cree and Visto v. Smartner in the mid-2000s. Firm-level results in more recent years include the Federal Circuit's denial of Cisco's appeals and mandamus petition in Ramot at Tel Aviv University v. Cisco (2020), a $110.7M Delaware jury verdict for TOT Power Control against Apple (June 2025), and the Federal Circuit's reversal and vacatur for Lambeth Magnetic Structures against Seagate. Attribution of any specific recent matter to this individual attorney could not be verified.

PTAB/IPR. Bunsow De Mory has a substantial PTAB practice — Patexia ranked it the top-performing PTAB firm for 2020–2025, and firm attorneys appear as counsel in IPR powers of attorney and patent-owner filings. I could not verify individual IPR or PGR appearances by this particular attorney.

Bar/education. Court filings (Howrey era) list California State Bar No. 60707. Education could not be verified from reliable public sources.
