Mark P. Scarsi

Mark P. Scarsi was a prominent patent litigator known for his focus on complex intellectual property disputes, particularly within computer software and related technologies. His practice frequently involved defending major technology companies against patent infringement allegations. Scarsi's deep technical background, including a decade as a software engineer on U.S. Navy defense projects, underpinned his approach to litigating sophisticated patent matters. He also handled Section 337 investigations before the U.S. International Trade Commission and advised clients on licensing and patent-related issues.

Throughout his private practice career, Mr. Scarsi primarily represented defendants, including large operating companies. The single tracked appearance, eDekka LLC v. Sally Beauty Supply LLC, reflects this preference where he served as Lead Counsel for the defendant. His client roster included Fortune 100 companies such as Apple Inc. and Lockheed Martin Corporation, consistently positioning him on the defense side in high-stakes patent infringement cases.

Before his judicial appointment, Mr. Scarsi was a partner at Milbank, Tweed, Hadley & McCloy (now Milbank LLP) from 2007 to 2020, where he led the firm's West Coast Intellectual Property Litigation & Technology practice and served as Co-Managing Partner of the Los Angeles office. Prior to joining Milbank, he was a partner at O'Melveny & Myers LLP (1998-2007) and an associate at Christie, Parker & Hale LLP (1994-1998).

Notable outcomes in his career include securing a complete defense verdict for Apple Inc. in a wireless technology patent infringement case brought by wi-LAN Inc., where the jury found no infringement and invalidated all asserted patent claims, dismissing a claim for $248 million in damages. He also successfully represented Google Inc. in a patent infringement suit concerning mobile platform location technology. While the tracked eDekka case did not provide a specific verdict for Sally Beauty Supply, the patent in question was later characterized as "demonstrably weak" by the court, with the plaintiff's arguments deemed "insupportable," leading to the case being found "exceptional." There is no information from the provided sources indicating regular appearances in PTAB or IPR proceedings.

Mr. Scarsi earned his B.S. and M.S. in Computer Science from Syracuse University and a J.D., magna cum laude, from Georgetown University Law Center. He was admitted to the California Bar in 1996, the New York Bar in 1998, and was registered to practice before the U.S. Patent and Trademark Office in 2003. He was confirmed as a federal district judge for the U.S. District Court for the Central District of California in September 2020.
