Matthew Seldin Dontzin

I'll research this attorney's background before drafting.

Let me verify bar admission, education, and firm/patent practice details.

Matthew Seldin Dontzin — Patent Litigation Practice Summary

Specialty and focus. Mr. Dontzin is a founding partner of the New York litigation boutique Dontzin Nagy & Fleissig LLP, where his practice is centered on high-stakes commercial and international litigation, white-collar defense, and art law — not on patent prosecution or patent-specific work as a standalone discipline (Human Rights First bio; Lawdragon "Lawyer Limelight"). His tracked patent matters involve the computer and network-security side of the field: Intellectual Ventures II's assertion of patents covering a hardware cryptographic co-processor ("crypto-engine" executing RSA and ECC encryption), network intrusion/anomaly detection, public-key certificate and digital-signature transaction methods, and related financial-services data-processing patents (S.D.N.Y. Nos. 13-cv-03777; related CBM/IPR filings over the '574 and '409 patents). The technology is thus cryptography/enterprise IT and financial-transaction systems rather than Wi-Fi standards, pharma, or mechanical arts.

Side preference. Both tracked appearances are for defendants (2 defendant, 0 plaintiff), and he is recorded as local counsel in each. The pattern is defensive representation of a large operating company — JPMorgan Chase & Co. and affiliated Chase entities — against a well-known patent-assertion entity, working alongside national IP lead counsel (Durie Tangri and Kirkland & Ellis). The firm's own general litigation description, by contrast, notes it represents both plaintiffs and defendants across subject areas, so the patent-specific sample here is narrow and skews defense-side.

Notable matters. In Intellectual Ventures II LLC v. JPMorgan Chase & Co. (S.D.N.Y., Judge Alvin Hellerstein), the defense team won a 2015 ruling invalidating three IV patents under 35 U.S.C. § 101 as abstract (a post-Alice result reported by Law.com's Litigation Daily), while IV voluntarily withdrew a fourth patent; the remaining '666 crypto-engine patent survived two JPMC non-infringement summary judgment motions before the case concluded. The firm has also publicly described "successfully invalidating three patents and securing voluntary dismissal of claims based on a fourth patent in a patent infringement suit brought by the largest patent troll operating in the U.S.," which corresponds to this matter. Mr. Dontzin appears on Federal Circuit papers in a related Intellectual Ventures II appeal as counsel for the defendant/appellant; I could not verify the appellate outcome from available sources, so no result is attributed here.

PTAB/IPR and credentials. The IV/JPMC dispute included parallel CBM and IPR proceedings against the asserted patents, but the available record shows Mr. Dontzin's own role as district-court local counsel rather than a documented personal appearance before the PTAB; I found no evidence of him as a regular IPR/PGR practitioner. He was admitted to practice in New York in 1984 and is a graduate of Hampshire College and New York University School of Law (J.D. 1983). Note: the firm's letterhead also lists Hon. Michael J. Dontzin (1993–2012), a different individual.
