Jeffrey S. Seddon, II

I'll research this attorney's background and verify details before writing the summary.

Let me verify PTAB/IPR work and the specific tracked cases.

Let me check the Apple v. Masimo result and any PTAB counsel listings.

Jeffrey S. Seddon II — Patent Litigation Summary

Specialty / focus areas. Seddon's practice centers on complex-technology patent litigation. Desmarais's own bio describes disputes spanning semiconductors, mobile communications, digital imaging, computer architecture, networking, and the Internet, with secondary work in trade secrets, trademarks, antitrust, and unfair competition. The tracked docket is consistent with that: DisplayPort/VESA display-interface standards asserted against Dell (General Video, LLC v. Dell Inc., W.D. Tex.), computer memory architecture in XMTT v. Intel, virtualization software in the Microsoft/ToutVirtual dispute, and networking/CLI technology in Arista Networks v. Cisco. The firm bio also lists biologics as a subject area, but the tracked cases do not show a pharma/biologics docket for him. A third-party analytics profile categorizes his experience primarily in computer architecture/software and communications.

Side preference. He is almost exclusively a defense-side litigator: 0 plaintiff-side appearances versus 7 defendant-side appearances in the tracked data, representing operating companies such as Dell, Microsoft, Intel, Cisco, Apple, Lenovo, and IBM. Two caveats worth noting for accuracy: the tracked list is small and under-populated (several entries are untitled), and the firm bio credits him with work for Intellectual Ventures (a patent monetization entity) and for IBM, and he was part of Apple's affirmative patent case against Masimo. So he is best described as a defense-focused litigator who has also worked on select plaintiff-side and NPE-adjacent matters, not a dedicated NPE prosecutor.

Firm context. Seddon is a partner in the New York office of Desmarais LLP, which he joined in 2014; he was elevated to partner effective January 1, 2022. Before Desmarais, he was an associate at King & Spalding LLP in New York (2011–2014), where he handled district court and ITC patent matters. He is not in-house.

Notable cases and outcomes. He was a key member of the Desmarais team defending Cisco in the Arista antitrust/IP litigation, which settled on the eve of trial with Arista paying Cisco $400 million. He was part of the team that won summary judgment of non-infringement for IBM against Parallel Networks' dynamic-web-page patents and drafted IBM's briefs on the Federal Circuit appeal, which ended in a Rule 36 affirmance. He was on the Intel team that won summary judgment of non-infringement in XMTT v. Intel (D. Del., Feb. 2023, Judge Kennelly), construing "serial processor" favorably to Intel. He is listed as Apple counsel in the Delaware Apple v. Masimo litigation, in which a jury found Masimo infringed two Apple Watch patents (Law360, Oct. 2024). In the tracked General Video, LLC v. Dell matter he is identified as a lead attorney for Dell/Dell Technologies before Judge Albright, defending standard-essential-style DisplayPort claims.

PTAB / IPR experience. The record I could verify shows him litigating district court cases that spawn IPRs rather than serving as PTAB counsel of record: Intel and Dell filed IPR petitions (e.g., IPR2025-01037/-01038) against General Video patents while he represented Dell in the parallel W.D. Tex. case, and Microsoft filed an IPR against ToutVirtual (IPR2026-00297). His published experience emphasizes district court, ITC, and Federal Circuit work; I did not find a well-sourced listing of him as counsel of record in PTAB proceedings, so IPR experience should not be overstated.

Bar / education. Admitted in New York (2012) and California (2014); admitted before the Federal Circuit and the E.D.N.Y., S.D.N.Y., and N.D. Cal. J.D., NYU School of Law, 2011 (cum laude); B.S. in Computer Science and B.S. in Philosophy, University of Maryland, 2008 (per the firm bio; partner elevation announcement lists the year as 2008).

Sourcing note: all of the above comes from the Desmarais LLP attorney bio and firm news items, court dockets/filings (CourtListener, Justia, Docket Alarm, USPTO PTACTS), and Law360. No social media or personal-detail sources were used.
