William I. Schwartz is a Senior Of Counsel at Morrison & Foerster LLP, where he focuses on patent litigation as part of a broader intellectual property and technology practice. His expertise encompasses business transactions and counseling involving intellectual property and technology, including licensing, development agreements, and joint ventures. He is particularly active in matters related to computers, software (both open source and proprietary), communications equipment (including smartphones and wireless devices), semiconductors, electronic commerce, and other advanced information technology.

Based on tracked appearances, Mr. Schwartz has represented clients on the plaintiff side in patent litigation. His client roster at Morrison & Foerster includes prominent technology and financial services companies such as Accenture, Visa, Netflix, Sprint Nextel, and Yahoo. This indicates a practice centered on representing established operating companies in complex IP disputes. He was also the founding co-head of Morrison & Foerster's Intellectual Property Group and has served as the firm's managing partner.

A notable case in his patent litigation experience is Visa USA Inc v. Cortex MCP Inc, where he represented Visa USA Inc as plaintiff. This case involved allegations of patent infringement related to "officially verifiable electronic representation (OVER) file" technology and "tokenization capabilities" in mobile commerce platforms. The dispute further involved related inter partes review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB), where Visa successfully challenged the patentability of several claims of Cortex MCP's patents. The district court case was subsequently stayed and then appealed to the Federal Circuit.

Mr. Schwartz is admitted to the California Bar since 1984. He earned his B.A. from Amherst College and his J.D. from the University of Chicago Law School. He has also been recognized by Best Lawyers for his work in Information Technology Law.
