Gaby LaHatte
Biography

Gaby brings a sophisticated understanding of clients’ business operations and the science on which they are built to help navigate litigation before the federal district courts, the U.S. International Trade Commission, and in appeals before the Federal Circuit. She counsels innovative companies on a broad range of technologies, including biologics, biosimilars, biotechnology, medical devices, spatial audio, vehicle control systems, artificial intelligence, telecommunications, and standard essential patents.
Clients call on Gaby to evaluate the merits of their intellectual property portfolios and craft out-of-the-box strategies to guide them to secure favorable outcomes, both before and following trial. She collaborates with witnesses, including inventors, to distill complex technical topics into compelling courtroom narrative. Some of her notable representative clients have included Genentech, Meta, Jaguar Land Rover, AbbVie, Janssen, and Medline, among others.
Gaby draws on insights gained during a secondment in the legal department of a leading biotechnology company, where she handled domestic and international patent assertion and patent portfolio development. She also leverages prior experience prosecuting biotechnology and mechanical patents at a regional intellectual property boutique, as well as undergraduate and graduate study in biochemistry.
Complementing her commercial work, Gaby maintains an active pro bono practice, including advising on matters involving tenant/landlord disputes, conservatorships, and veterans benefits.
Gaby serves as a member of the Eastern District of Texas Bench Bar Planning Committee and the Federal Circuit Bar Association’s model jury instruction subcommittee, and she frequently serves on panels regarding patent litigation. She is also a member of the San Francisco Bay Area Inn of Court.
Prior to joining Weil, Gaby was a member of the Intellectual Property practice of another top global law firm. She previously served as a law clerk to Judge Kathleen O’Malley of the U.S. Court of Appeals for the Federal Circuit and chief staff attorney and law clerk for Chief Judge Leonard Davis of the U.S. District Court for the Eastern District of Texas.
