Sean James O'Hara

Sean James O'Hara is a patent litigation attorney with Kercsmar & O'Hara PLLC, specializing in intellectual property litigation and complex commercial disputes from the firm's Scottsdale, Arizona office. His practice encompasses patent infringement, trademark infringement, and trade secret misappropriation. The cases he has handled suggest a focus on software and internet-related technologies, specifically involving video-streaming and content-delivery technology.

O'Hara demonstrates experience representing both plaintiffs and defendants in patent disputes. His tracked appearances include representing ART Research and Technology LLC as a plaintiff and defending ART Research and Technology, LLC against Google LLC. This indicates a balanced practice working for both patent assertion entities and operating companies.

A notable engagement includes representing ART Research and Technology LLC in ART Research and Technology LLC v. Google, LLC et al. in the Northern District of California. In this case, which involved patents related to video-streaming and content-delivery technology, the court found all four asserted patents invalid under 35 U.S.C. § 101, ruling them patent-ineligible abstract ideas. ART Research subsequently waived its appeal rights, resulting in a final judgment for Google and YouTube. Additionally, he was counsel for the patent owner, ART Research and Technology, LLC, in an Inter Partes Review (IPR2025-01405) initiated by Google LLC, demonstrating experience in PTAB proceedings.

Sean O'Hara began his legal career in 2006 after graduating from The University of Kansas School of Law.
