Patent Trial Lawyer Eugene Goryunov Joins Haynes and Boone's Chicago Office

November 06, 2019

Patent trial lawyer Eugene Goryunov has joined Haynes and Boone, LLP as a partner in the firm’s IP Litigation Practice. He will lead the firm’s Chicago post-grant review trials practice.

Eugene represents clients in complex patent litigation matters involving diverse technologies from consumer goods to high technology to medical devices and therapeutics. He regularly serves as first-chair trial counsel in post-grant review trials (IPR, CBMR, PGR) at the USPTO on behalf of both petitioners and patent owners. To date, he has led more than 200 such trials, serving as first-chair counsel in more than half. Eugene is also deeply involved as trial counsel in all aspects of cases in federal courts, at the USITC involving Section 337 investigations, and in appeals at the Federal Circuit.

“We are endeavoring to meet the needs of our clients by adding talented practitioners like Eugene, who has a highly regarded practice handling patent trials before the Patent Trial and Appeal Board,” Partner David McCombs said. “He enhances the growth and reputation of our nationwide IPR practice.”

“Haynes and Boone was very attractive to me given its industry recognition and reputation in post-grant review trials. I am excited to join the firm’s growing Chicago office,” Eugene added.

Eugene’s move follows the recent announcements of two other veteran IP lawyers joining the firm’s Chicago office – Ralph Gabric and Laura Beth Miller – who boast decades of experience handling high-profile IP disputes.

“Eugene fits in perfectly with our established IPR practice, and he will help us sustain our momentum in the Chicago market,” said Jim Shimota, a partner in Haynes and Boone’s IP Litigation Practice and the managing partner of the Chicago office.

Prior to joining Haynes and Boone, Eugene was a partner in the Chicago office of Kirkland & Ellis LLP, where he was instrumental to the firm’s post-grant review practice. He filed some of the first-ever IPR petitions, served as the firm’s post-grant review trial practice knowledge manager, and co-founded the PTAB Bar Association. As a result, Eugene has earned significant industry recognition including top ratings on Managing Intellectual Property’s Top 50 Petitioner Attorney at the PTAB (2018) and Patexia’s Top 50 Most Active and Best Performing Attorneys in PTAB Trials (2017-2019). Before practicing law, Eugene was an accomplished software engineer developing e-commerce solutions at Cardinal Health in McGaw Park, Illinois.

Since the America Invents Act’s new post-grant review trials were implemented in 2012, Haynes and Boone’s IP Practice has been a leader in helping clients protect their patents and invalidate others’ claims at the USPTO. Haynes and Boone is among the top 10 law firms filing IPRs on behalf of the Petitioner, with an institution rate of 93 percent and a final decision rate of 91 percent for canceling claims (Docket Alarm, 2018). The firm regularly represents clients in an array of industries, including Internet, computer software, networks, protocols, information security, telecom equipment and standards, energy, imaging systems, semiconductor devices and fabrication, automotive, and business methods.

Haynes and Boone is an international corporate law firm with offices in Texas, New York, California, Charlotte, Chicago, Denver, Washington, D.C., London, Mexico City and Shanghai, providing a full spectrum of legal services in energy, technology, financial services and private equity. With more than 575 lawyers, Haynes and Boone is ranked among the largest U.S.-based firms by The National Law Journal, The American Lawyer and The Lawyer. It also ranks among the nation’s most recommended law firms by general counsel, according to BTI Consulting Group’s “Most Recommended Law Firms 2019” report.
