Firm overview
I'll research Hecht Partners to verify its profile, size, and IP practice details before drafting.
Let me verify the notable cases and PTAB activity.
Hecht Partners LLP is a trial-focused litigation boutique headquartered at 125 Park Avenue in New York City. It is not a BigLaw firm or a traditional patent prosecution shop; Chambers USA carries the firm in a spotlight profile for Intellectual Property (trademark, copyright and patent litigation, plus trade secret work in New York), and the firm's own materials describe it as a boutique with additional offices in California, Minnesota, Florida and Texas. Size figures are inconsistent across sources and should be treated as approximate: U.S. News lists one U.S. office with 14 lawyers, while the firm's August 2026 announcement of three IP partners arriving from King & Wood Mallesons states the IP group alone had grown to 15 lawyers. No AmLaw ranking was located, which is consistent with a boutique of this size.
IP litigation specialty. The firm's practice description covers patent, copyright, trademark and trade secret litigation, and the tracked docket reflects that breadth. Technologically, the portfolio skews toward electronics and communications: Wi-Fi standards work (notably Wi-Fi 6/OFDMA and Trusted Platform Module functionality in the Proxense campaign), biometric authentication and secure payment technology, semiconductors, computer hardware and software, and inkjet printhead/printing hardware (the Slingshot Printing matters). The firm also has a distinct life sciences capability — partner Delphine Knight Brown's bio describes lead-counsel Hatch-Waxman experience, and of-counsel attorneys Sarah Cork and Wen Wu list BPCIA, ANDA and PTAB work. Copyright and DMCA work (Corellium, Hanagami, BMG) is a secondary but visible strength.
Side preference: genuinely both sides, with a meaningful plaintiff/patent-owner tilt. The tracked appearances are 12 plaintiff-side and 8 defendant-side, but the defendant-side entries need a caveat: several of them are parallel PTAB or mirror-image captions in which the firm's client is the patent owner defending validity, not an operating company accused of infringement (e.g., Unified Patents v. Proxense, Intel Corp. v. Proxense, Canon U.S.A. v. Slingshot Printing). In substance the firm is best characterized as a patent-owner/plaintiff-side enforcement and defense-of-validity shop that also accepts full IP defense work for international clients — a point Michael DeVincenzo made explicitly when his team joined in August 2026. It has not been a routine defense-side firm for operating companies in the tracked matters.
Notable matters. The most prominent campaign is Proxense, LLC's multi-front assertion of biometric authentication and wireless patents against Samsung, Google, Apple, Microsoft and Intel in the Western District of Texas before Judge Alan Albright. The firm kept those cases in Albright's court notwithstanding changed assignment rules (including a favorable Federal Circuit mandamus ruling involving Microsoft in 2024); Proxense v. Samsung settled on the eve of trial in 2023, Proxense v. Google was dismissed with prejudice in January 2025, and Proxense v. Intel settled around March 2026, while the Apple and Microsoft actions have been stayed. In Slingshot Printing LLC v. Canon U.S.A., the firm represented the patent owner in S.D.N.Y. infringement suits that were stayed pending IPR; the PTAB invalidated the challenged claims and the Federal Circuit affirmed across multiple Slingshot patents in July 2026 — an adverse outcome for the firm's client (appellate briefing was handled by other counsel). On the copyright side, David Hecht was lead counsel for Corellium in its successful defense against Apple (summary judgment win, with Apple dropping remaining claims before trial), and the firm secured a reported $25 million jury verdict for BMG Rights Management against Cox, described in press accounts as the largest verdict in Virginia in 2015.
PTAB / IPR practice. The firm has a real, if lean, post-grant capability. Of-counsel Patrick Maloney states he has represented clients in over 200 post-grant proceedings (IPRs, CBMs, ex parte reexaminations) and was ranked 9th on Managing IP's 2021 list of top lawyers for patent owners in IPRs and 19th by Patexia among most-active patent-owners' counsel since 2015 — figures sourced from the firm's own bio, not independently verified here. The firm's PTAB posture is predominantly patent-owner defense: it argued for Proxense in IPRs brought by Apple, Microsoft and Intel and represented SitNet against Meta, where the Board found the claims unpatentable (final written decision September 2025; SitNet noticed an appeal in November 2025). Proxense-related PTAB litigation has also generated public policy activity, including firm commentary on the USPTO's discretionary-denial framework and an appeal contending the Board improperly stayed a parallel reexamination.
Practice leaders. David L. Hecht (founder and co-managing partner; registered patent attorney and electrical/computer engineer; repeatedly listed in IAM Patent 1000 since 2020) and Maxim Price (founding partner and New York co-partner-in-charge; IAM Patent 1000 since 2023; formerly Jones Day and Quinn Emanuel) co-lead the IP team. Delphine Knight Brown leads much of the life sciences/Hatch-Waxman work, and Peter Park, a recent arrival and former head of IP litigation at Analog Devices, adds semiconductor and electrical engineering depth. The August 2026 additions of Michael DeVincenzo, Andrea Pacelli and Charles Wizenfeld further build out trial, ITC and PTAB capacity in electrical, semiconductor and telecommunications matters.
Sourcing note: firm overview, attorney bios and office footprint are drawn from hechtpartners.com, the Chambers USA spotlight profile, U.S. News' firm page, and the firm's August 2026 lateral-hire announcement (National Law Review/EIN Presswire). Case outcomes are drawn from court and PTAB filings, Federal Circuit opinions, Law360/ip fray/IPWatchdog reporting, and RPX litigation summaries. No AmLaw revenue or headcount ranking was located; treat lawyer counts as approximate.
