Ian B. Crosby

Ian B. Crosby is a partner at Susman Godfrey L.L.P. with a practice focused on high-stakes intellectual property litigation. His work encompasses patent, copyright, and antitrust matters in federal courts and before the U.S. International Trade Commission. While his patent experience covers technologies including e-commerce and software, he has become a leading authority in litigation related to artificial intelligence (AI), representing both rights holders and technology platforms in this emerging area of law. His expertise in technically complex subject matter extends to software, electronics, and aerospace.

The provided data indicates a plaintiff-side appearance in Almondnet, Inc. v. Microsoft Corporation, and while the case list is limited, public records show Crosby has a balanced practice representing both plaintiffs and defendants. He has served as lead counsel for plaintiffs like The New York Times in its copyright suit against Microsoft and OpenAI, and for Chegg, Inc. in its monopoly suit against Google. On the defense side, he has successfully represented companies like Zillow Group, Inc., securing the dismissal and invalidation of multiple patents asserted by IBM.

Crosby has experience in post-grant proceedings before the Patent Trial and Appeal Board (PTAB), where he has successfully defended patentability in inter partes review (IPR) on behalf of a patent owner. His representative matters also include achieving a favorable settlement for patent owner AlmondNet after defeating multiple covered business method review petitions.

He earned his law degree from The University of Texas School of Law in 1998 and is a member of the Washington state bar.
