Brown Rudnick strengthens IP litigation and PTAB practices with addition of Eugene Goryunov 

WASHINGTON, D.C., June 11, 2025 – Brown Rudnick announces the arrival of partner Eugene Goryunov, a leading intellectual property trial attorney who has appeared in and led more than 500 proceedings before the US Patent and Trademark Office (PTO). Goryunov will be based in the firm’s Washington, D.C., office and will serve as Co-Chair of Brown Rudnick’s Patent Trial and Appeals Board (PTAB) practice alongside Houston partner Jayne Piana. Goryunov is ranked as a leading patent lawyer by Chambers USA, Intellectual Asset Management, and Managing Intellectual Property. 

Brown Rudnick is also pleased to announce that Houston partner Erick Robinson will become Chair of Brown Rudnick’s Patent Litigation practice. Robinson and Piana joined Brown Rudnick’s Houston office in 2024 as part of an eight-lawyer intellectual property litigation team in Houston. 

Goryunov is a highly experienced trial lawyer who regularly serves as first-chair trial counsel in post-grant review trials (IPR and PGR) on behalf of both petitioners and patent owners at the PTO. He also regularly litigates cases in Federal courts across the US, appeals at the Federal Circuit, and represents clients in Section 337 investigations at the US International Trade Commission (ITC). He has represented a broad range of clients in complex patent matters involving technologies, including consumer goods, high technology, networking, wireless telephony, medical devices, and therapeutics. He also regularly speaks and authors articles on artificial intelligence and has advised clients on patent prosecution, portfolio management, and litigation relating to artificial intelligence. 

Goryunov is a co-founder of the PTAB Bar Association, has authored Trial Lawyer’s Guide to Post Grant Patent Proceedings, a leading treatise published by Lexis Nexis, and serves on the Editorial Board of The Patent Lawyer, as Editor-in-Chief of the PTAB Bar Association’s Round-up of Round-ups, and as lead editor of Westlaw’s “Tips and Tricks at the PTAB.”  

Goryunov stated: “Brown Rudnick has an exceptional reputation for IP litigation and post-grant review trials. I’m looking forward to bringing my PTAB experience to support BR’s clients and funded litigation.” 

Ian DiBernardo, Chair of Brown Rudnick’s Intellectual Property Litigation practice, commented: “We are thrilled to welcome Eugene. Together with our existing track record of notable trial verdicts, Eugene’s experience in hundreds of IPRs positions us to handle complex litigation matters of any size for both patent owners and defendants, all in-house. He is a natural fit to join Brown Rudnick’s world-class intellectual property practice.” 

Prior to joining Brown Rudnick, Goryunov was a partner at Haynes Boone, where he was instrumental to the firm’s post-grant review practice and co-chair of the firm’s AI and Deep Learning practice. Before law school, Goryunov worked as a software engineer for more than five years at Cardinal Health.
