Jacob C. Vannette

I'll research this attorney across multiple sources.

Let me verify the firm history and the tracked cases directly.

Professional Summary — Jacob C. Vannette

Focus areas. Vannette's practice is patent-heavy IP litigation with a mechanical-engineering bent (B.S., Villanova) but a docket that skews toward electronics and communications. His two identified tracked matters sit in the video-codec / standard-essential-patent space: DivX, LLC v. Realtek Semiconductor (accused video-processing SoCs for smart TVs, litigated in parallel at the ITC and D. Del.) and Nokia Technologies Oy v. Paramount (Nokia's video-coding SEP campaign against streaming/content companies). Firm-published descriptions of his work list control systems, medical devices, electronics, communication systems and materials science, plus matters involving Wi-Fi routers and mesh networking, OLED displays, cloud/AI security, rail and transportation equipment, and a pharmaceutical (multiple sclerosis) dispute. Third-party analytics tagging his name show the heaviest concentrations in communications and mechanical/manufacturing technologies, with smaller semiconductor/optics and software/security counts.

Side preference. On this platform's tracked record he is defense-side only (0 plaintiff, 3 defendant), which fits the pattern of the tracked matters — Realtek (component supplier), Paramount (content company), and one further unspecified defendant-side matter. That said, his own firm bio shows he is not a defense-only lawyer: he is listed as trial counsel for Estelgia LLC as plaintiff in a six-patent Wi-Fi mesh-networking case against Plume, Linksys, ASUS and D-Link. The fair characterization is a both-sides litigator with a defense tilt and substantial work for suppliers and operating companies rather than a PAE-focused prosecution practice.

Firm context. His tracked appearances are under K&L Gates, where he handled the DivX/Realtek ITC and Federal Circuit work. His current published profile is as an associate in the Washington, D.C. office of Latham & Watkins, whose bio notes prior litigation and patent-prosecution experience at "another major international law firm" — consistent with the K&L Gates period. (The K&L Gates-to-Latham move is inferred from matching details — D.C., mechanical engineering, ITC electronics defense, video-codec SEP work — rather than a single source stating the transition; the Latham and K&L Gates profiles should be treated as the same attorney, but that link is not independently confirmed.) He earlier clerked for Judge Sharon Prost of the U.S. Court of Appeals for the Federal Circuit and Judge Robert W. Schroeder III of the E.D. Tex.

Notable matters and outcomes. In DivX v. Realtek, the ITC investigation (337-TA-1222) ended with Realtek terminated from the investigation after DivX withdrew its complaint; Realtek then pressed a sanctions motion (denied by the ALJ) and appealed the district court's dismissal of DivX's claims without prejudice to the Federal Circuit (Appeal Nos. 2023-1095 and 2024-2061), where Vannette appears on the Realtek appellate briefs. Reported results are therefore mixed rather than a clean client win. He is also identified on the Latham team that secured dismissal of counterclaims for Recor Medical against Medtronic (N.D. Cal., 2025), recognized in American Lawyer's Litigator of the Week coverage. Details and outcomes for Nokia Technologies Oy v. Paramount could not be verified from the sources reviewed.

PTAB / IPR. Both his firm bio and third-party analytics indicate regular PTAB work alongside district court and ITC matters, with Federal Circuit appellate activity as well; specific IPR/PGR proceeding numbers were not verified.

Bar / education. Admitted in the District of Columbia and Illinois; registered before the USPTO. J.D., University of Illinois College of Law (2016); B.S., Mechanical Engineering, Villanova University (2013).

Caveats: The third tracked case is untitled in the source data, so it is not described. Claims about firm succession and the Recor/Medtronic result rest on firm-published material rather than court records.
