Ben Christoff

I'll research this attorney's professional background before drafting the summary.

Let me dig deeper into his PTAB experience and notable case outcomes.

Let me verify his prior firm history, bar admissions, and the one defense-side matter.

Professional Summary — Benjamin J. Christoff

Practice focus. Christoff is a patent trial and appellate litigator at Fish & Richardson (Washington, DC office), where he has handled matters spanning semiconductors and memory products, wireless communications, computer networking and databases, medical devices, digital rights management, near field communication, chemical processes and biofuels. His chemical engineering background anchors the technical side of his practice, and his published bio emphasizes oral advocacy work at claim construction, jury instruction, and JMOL stages, plus direct and cross-examination at trial. The tracked docket list reflects a substantial, active enforcement practice for the Rare Breed Triggers/ABC IP family of patents covering forced-reset rifle triggers — a mechanical/consumer-product niche rather than a standard-essential or pharma portfolio.

Side preference. The tracked caseload skews plaintiff-side (4 of 5 appearances), and he is currently one of the core Fish & Richardson attorneys prosecuting the Rare Breed/ABC IP trigger patent campaign across multiple districts and the Federal Circuit. That said, his practice is genuinely two-sided: public filings show him on briefs for Samsung in the Netlist v. Samsung Federal Circuit appeal, and his Fish bio describes defending household-name consumer electronics companies and a leading auto manufacturer in cellular-communications litigation. One tracked appearance is on the defendant side (ABC IP LLC v. Hoffman, listed as lead counsel); note that public filings in the similarly named ABC IP/Rare Breed v. Hoffman Tactical (E.D. Tenn.) show Fish & Richardson representing the plaintiffs in that dispute, so the defense-side designation may relate to a separate or differently captioned matter and should be confirmed before relying on it.

Notable matters. Prominent tracked cases include the Rare Breed Triggers/ABC IP enforcement group — Rare Breed Triggers v. Tyler Harrison, v. Peak Tactical LLC/Partisan Triggers, and v. Post Falls-Ish — now consolidated in an MDL (No. 3176, E.D. Tex.). In ABC IP LLC v. Peak Tactical LLC (D. Wyo.), he was on the appellant team that moved to expedite appeal of a denied preliminary injunction; the Federal Circuit affirmed the denial on September 15, 2026 (No. 2026-1527, Rule 36 judgment). A parallel E.D. Tenn. action against Hoffman Tactical reportedly produced a preliminary injunction in the plaintiff's favor in February 2026. He also appeared in the In re NEO Wireless patent MDL (E.D. Mich.).

PTAB / IPR experience. His Fish bio lists the Patent Trial and Appeal Board as a regular venue, and he appears in PTAB records as counsel in IPR2023-00309 involving Slingshot Printing's '864 printing patent, including the patent owner's appeal to the Federal Circuit following a final written decision holding the challenged claims unpatentable. This is real but not high-volume IPR work; no evidence found of a large standalone post-grant docket.

Bar, education, and firm history. Fish & Richardson elevated him to Principal effective January 1, 2025. He previously clerked for Judge Jimmie V. Reyna of the U.S. Court of Appeals for the Federal Circuit, and earlier worked at McKool Smith and Crowell & Moring (search-indicated; firm-tenure dates not independently confirmed). He co-authored the third and fourth editions of Patent Law in a Nutshell with retired Federal Circuit Chief Judge Randall R. Rader. Education: J.D., University of Dayton School of Law; LL.M., George Washington University Law School; B.S. in chemical engineering, University of Dayton. He is admitted in the District of Columbia (Bar No. 1025635) and registered with the USPTO (Reg. No. 70127).

Note: a few items above (prior firm dates, and the one defense-side tracked matter) are not fully verifiable from public sources and should be confirmed against firm records.
