David Gosse

I'll research this attorney before drafting. Let me run several searches in parallel.

Good material. Let me verify his current firm, move to Nokia, bar/education, and a couple of case specifics.

David A. Gosse — USPTO Reg. No. 61,511

Specialty / focus. Gosse's practice centers on patent litigation and PTAB trial work, with a prosecution side covering patent acquisition. Fitch Even's partner announcement describes his matters as involving complex process control algorithms, gift card activation systems, industrial printing hardware and software, DRAM and Flash memory, RISC processors, and mechanical devices. His tracked cases are inkjet-printing hardware disputes, consistent with a mechanical/electro-mechanical and electronics-heavy docket rather than pharma or life sciences.

Side preference. His tracked record is entirely plaintiff-side: three appearances, all as counsel for patent owner/plaintiff and none for a defendant, including the Slingshot Printing and Canon matters. His verifiable PTAB appearances point the same way — he served as lead or backup counsel for patent owners in IPRs involving Ancora Technologies, Vertiv, Lone Star Silicon Innovations, and Quartz Auto Technologies, and Patexia's 2022 IPR Intelligence Report ranked him among its top 100 most-active attorneys representing patent owners. The pattern is a patent-owner/asserting-side practice, not an operating-company defense practice.

Firm context. The tracked appearances list Fitch, Even, Tabin & Flannery LLP (Chicago), where he spent over a decade and was elected partner effective January 1, 2017; he also chaired the firm's PTAB-related programming and the AIPLA PTAB Trial Committee. He has since moved in-house and is now Senior Licensing Attorney, Business Group IP, at Nokia Technologies, where his public profiles describe him as managing and resolving complex patent disputes and negotiating settlements and licenses. Note the timing gap: the tracked district court and IPR matters date to his Fitch Even tenure, so the case list reflects his prior firm, not his current employer.

Notable matters and outcomes. The most prominent tracked dispute is the Slingshot Printing LLC–Canon U.S.A. inkjet printhead campaign. Slingshot sued Canon for infringement in the Eastern District of New York (complaints filed January and April 2022), and Canon counterattacked with IPRs; the district court cases were stayed. On appeal, the Federal Circuit affirmed PTAB obviousness holdings invalidating claims of Slingshot's U.S. Patents 7,152,951; 7,290,864; 7,484,823; and 7,594,708 (nonprecedential dispositions, July 2026, plus a Rule 36 judgment). These were adverse outcomes for his client — the patent owner — and the Federal Circuit briefing in those appeals was led by MoloLamken with Fitch Even attorneys Mark Borsos and Paul Henkelmann also listed, so Gosse's role in the appeals themselves is not separately documented in the sources reviewed.

PTAB / IPR experience. Yes, substantively: he appears in multiple IPR proceedings as patent-owner counsel, has presented firm webinars on discretionary institution under Fintiv and on secondary considerations at the PTAB, and writes on PTAB practice (e.g., IPWatchdog commentary on the Board deciding grounds beyond the petition).

Bar / education. J.D., Chicago-Kent College of Law; B.S., Mechanical Engineering, Northwestern University; registered to practice before the USPTO (Reg. No. 61,511). He teaches "Oral Advocacy for the IP Lawyer" as an adjunct at Chicago-Kent and is a former Illinois Super Lawyers Rising Star for IP litigation. His specific state bar admissions were not independently confirmed in the sources reviewed.
