Sheryl Koval Garko



Co-chair of Orrick’s 100-lawyer Intellectual Property litigation practice, Sheryl Koval Garko is an experienced trial lawyer who focuses on high-stakes intellectual property litigation. Clients hire Sheryl for her creative, strategic, business-focused advice enriched by her extensive courtroom experience and working knowledge of a wide range of technologies.

Over the course of her career, she has represented clients ranging from Fortune 50 companies to start-ups in trademark, copyright, false advertising, and trade secret litigations and at trial. She has worked with leading technology companies and some of the most recognizable brands in the world, including New Balance, Williams-Sonoma, Carnival, and Microsoft. She has tried cases to both judges and juries in federal courts across the United States and is experienced practicing before the U.S. Patent and Trademark Office’s Trademark Trial and Appeal Board and the International Trade Commission. Through her trial work, she has developed deep expertise in litigating novel and complex damages issues in IP cases and leveraging survey work. 

Sheryl most recently earned a complete victory at trial on behalf of client Carnival in a patent and breach of contract matter related to theft of Carnival intellectual property. Following an 8-day trial in the Southern District of Florida, the jury deliberated for three hours and returned a verdict in favor of Carnival on all counts, awarding $21 million in damages.

She honed her skills in high profile, precedent setting cases. Sheryl represented Aereo against the major U.S. television networks in defense of its novel, industry-disrupting system for providing internet access to over-the-air broadcast television. That case ultimately went to the Supreme Court, which addressed copyright law issues of first impression. Sheryl currently represents Microsoft litigating novel issues related to the intersection of generative AI, copyright, and trademark law.

Having prepared countless cases for trial, Sheryl has a clear understanding of the importance of identifying litigation strategy early on to direct the case in a cost- effective and efficient manner. Sheryl also leverages her wealth of experience to counsel clients on strategies to protect intellectual property when avoiding litigation is a strategic business priority.

Having also litigated a number of patent cases throughout her career, she brings to each matter a unique understanding of the intersection of copyright, trademark, trade secret and patent law. A superb communicator, she is able to explain diverse areas of complex technology to a judge or jury.

Sheryl has been consistently named as one of the leading intellectual property litigators in the world by World Trademark Review 1000, a peer and client survey. In its 2017 publication, WTR 1000 described her as “'highly recommended’ for her ‘helpful and creative advice,’ which is ‘always of first-rate quality.’” In the 2018 edition, WTR 1000 stated that Sheryl “offers significant firepower to any contentious mandate.” In the 2021 edition, WTR 1000 said Sheryl ”puts her heart and soul into driving favorable outcomes.” In 2022 Sheryl and her team were lauded for being “tried and tested” in litigation and “emerging victorious in many forums. And in 2023, they were praised for “steering [clients] through complex litigation,” with work that was quick, efficient and “with the highest level of integrity.”
