Sarah Guske
Sarah Guske is a first-chair trial lawyer who counsels technology clients and other Fortune 500 companies in patent litigation in US district courts and the US Court of Appeals for the Federal Circuit and in Patent Trial and Appeal Board (PTAB) trials. In her practice, focused on high-stakes competitor litigation, she leverages her technical background in electrical engineering and physics and her trial experience to serve clients in the San Francisco Bay Area of California and beyond in the United States.
Companies in the technology and telecommunications industries seek out Sarah for her decades of experience litigating patent disputes to develop robust litigation strategies, mitigate risk, and safeguard their innovations. Her strategic use of inter partes reviews (IPRs) and trial experience has helped clients avoid potential legal liabilities. Sarah recognizes that litigation can interfere with a client’s focus on its core business. Whether it is a client’s first litigation, first bet-the-company matter, or one of many legal battles the company is facing, Sarah takes the time to thoroughly understand each client’s short- and long-term goals to design strategies that support the client’s business strategy.
Sarah frequently speaks about trial strategy with a focus on defending against willfulness allegations and on using IPRs in district court cases. She has also served as an adjunct professor teaching patent law and litigation at universities such as the University of California College of Law, San Francisco (formerly UC Hastings), the University of Colorado, and the University of Denver.
Before joining Morgan Lewis, Sarah served as the department chair of another global law firm’s California intellectual property groups.
