Keith Orso

Keith Orso is an accomplished patent litigator and an Of Counsel attorney at Irell & Manella LLP, where he also serves on the firm's Management and Executive Committees. His practice encompasses a broad range of technologies, including computer architecture, communications, medical devices, pharmaceuticals, and biotechnology. While the specific technology of the tracked case DataTreasury Corporation v. NCR Corp. (where he represented the defendant) is not detailed, his firm profile highlights his experience across these diverse fields, consistent with his master's degree in Chemical Engineering.

Orso primarily represents defendants in patent infringement actions. The tracked data shows one appearance on the defendant side and none on the plaintiff side. This aligns with his notable representations, which include defending companies such as Texas Instruments against allegations relating to microprocessor architecture, where his team secured summary judgments of noninfringement that were affirmed on appeal. He also represented Atmel Corporation in a patent infringement suit concerning random number generators. A significant outcome includes his counsel for St. Jude Medical Inc., where a jury returned a verdict of willful infringement and awarded $27.1 million in damages in a case involving vascular closure devices.

Orso possesses substantial experience in Patent Trial and Appeal Board (PTAB) proceedings, particularly in Inter Partes Reviews (IPRs). He successfully represented Gilead Sciences against four IPR petitions filed by Mylan Pharmaceuticals concerning patents related to the HIV drug tenofovir disoproxil fumarate, with the USPTO declining to institute any proceedings. He achieved a similar outcome for Biogen Inc. in an IPR petition related to the biologic rituximab. His practice includes defending major life sciences companies, having successfully defended Genentech and Biogen against over two dozen IPR petitions, securing numerous non-institution decisions and favorable outcomes.

Keith Orso was admitted to the California Bar in 2001. He earned his J.D. from UCLA School of Law, an M.S. in Chemical Engineering from the University of Texas at Austin, a B.S. in Engineering from Harvey Mudd College, and completed requirements for a major in Economics from Claremont McKenna College.
