Orion Armon


I guide innovative companies through the intricacies of patent litigation disputes in the federal courts and in Patent Office invalidity proceedings.

Orion Armon is an experienced trial lawyer who focuses on multi-venue, complex patent litigation matters in United States district courts, the Patent Office Patent Trial and Appeal Board, and before the Court of Appeals for the Federal Circuit. Orion has litigated cases involving monoclonal antibodies for treating solid tumors and cancers of the blood under the abbreviated pathway for biosimilars (BPCIA), hydrogel surgical adhesives and other medical devices, and computer hardware and software technologies. Orion’s litigation victories before the Federal Circuit Court of Appeals and Patent Trial and Appeal Board have changed the law. Most notably, as lead counsel for Enfish, Orion developed the litigation and appellate strategy and argued the appeal that led to Enfish’s victory over Microsoft in Enfish, LLC v. Microsoft Corp., 2015–1244 (Fed. Cir. 2016). The Enfish decision helped settle the law on patent eligibility under 35 U.S.C. § 101 and is one of the most-cited Federal Circuit precedents since 2016.
