PALO ALTO, Calif. / Nov 15, 2023 / Business Wire / Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, today announced it intends to appeal yesterday’s verdict in the U.S. District Court for the District of Delaware related to intellectual property claims brought against Guardant by TwinStrand Biosciences, Inc. and University of Washington.

“We strongly disagree with this decision and will vigorously appeal for its overturn,” said Helmy Eltoukhy, Guardant Health co-founder and co-CEO. “We believe the ruling ignores the strengths and merits of our R&D and intellectual property, which we painstakingly developed for over a decade.”

Guardant remains confident that it did not infringe the asserted patents, and the company expects to file additional motions with the U.S. District Court for the District of Delaware and appeal to the U.S. Court of Appeals for the Federal Circuit.
