The Glennon Law Firm

Firm overview. The Glennon Law Firm, P.C. is a Rochester (Pittsford), New York-based boutique litigation firm founded in 2014 by Peter J. Glennon, with offices in Albany, Buffalo, and New York City (per firm announcements covered by Law360 Pulse and the Greater Rochester Chamber). It is a regional commercial-litigation shop, not an IP specialty firm: its own practice description centers on business/commercial disputes, employment and labor litigation, non-compete work, and matrimonial and trust-and-estate matters for professionals and business owners, plus a marketed local-counsel service for out-of-state lead counsel in the Northern and Western Districts of New York. It has no AmLaw or Chambers patent ranking; its recognitions are regional (Best Lawyers / Best Law Firms in commercial litigation and employment, Super Lawyers). The firm does not publish an IP/patent practice group.

IP litigation specialty and side preference. The firm's entire tracked patent docket consists of two appearances, both as plaintiff-side local counsel for Flexiworld Technologies, Inc. against Xerox Corporation in the Western District of New York (Peter John Glennon in both). Flexiworld is a licensing/patent-assertion entity, and the underlying technology is software/networking — wireless and "driverless" mobile printing, including Xerox AirPrint, ConnectKey, and Print-and-Scan app functionality — rather than standards-essential Wi-Fi, pharma, or semiconductor work. Given the tracked count (2 plaintiff appearances, 0 defendant-side) and the firm's own description, the firm's patent role is best characterized as regional local counsel for NPE plaintiffs; it does not appear to lead patent merits work or defend operating companies. The firm's website confirms it handles local filings, pro hac vice sponsorship, discovery coordination, and court appearances for lead counsel.

Notable cases and outcomes. The tracked matters are the four related actions Flexiworld Technologies, Inc. v. Xerox Corporation, Nos. 6:23-cv-06370 through -06373 (W.D.N.Y., filed June 29, 2023), consolidated before Judge Elizabeth A. Wolford with Magistrate Judge Marian W. Payson. Flexiworld asserted roughly a dozen patents covering mobile/wireless printing against Xerox printer lines and apps; Xerox answered with counterclaims, represented by Hodgson Russ and McKool Smith, while Flexiworld's lead counsel was Nelson Bumgardner Conroy PC. Public docket reporting indicates all four suits were dismissed with prejudice after a negotiated settlement roughly eleven months after filing (circa mid-2024), with each side bearing its own costs — no verdict, damages award, or merits determination, and no Federal Circuit appeal. The dismissal is consistent with Flexiworld's pattern of settling with printer OEMs.

PTAB/IPR practice. There is no public evidence that The Glennon Law Firm has an IPR/PGR filing or defense practice; its tracked work is district-court local counsel only, and PTAB proceedings in this dispute (if any) would have been handled by the parties' lead patent counsel. I found no PTAB docket attributing filings to the firm.

Key partners. Peter J. Glennon (founder/principal, admitted 2005, Albany Law School; former Nixon Peabody litigator; Best Lawyers-recognized in commercial litigation) is the only firm attorney appearing in the tracked patent cases. Other senior litigators on the firm's public roster — Kimberly A. Glennon (employment/labor) and Tracey B. Scarpello (commercial and product-liability defense) — are recognized in non-patent fields, and no firm attorney is publicly ranked for IP or patent litigation. Anyone evaluating the firm for patent work should treat it as a capable upstate-New York local-counsel resource rather than a substantive IP litigator.
