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.

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 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.

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.”
