Guardant Health Wins $292M False Advertising Case Against Natera in Colorectal Cancer Test Dispute

Guardant Health has achieved a notable legal victory against its competitor, Natera, in a high-profile false advertising lawsuit. A federal jury in the U.S. District Court for the Northern District of California awarded Guardant $292.5 million, a sum that includes $175.5 million in punitive damages, marking one of the largest verdicts in a false advertising case in history[1][2]. The case began in May 2021, focusing on claims that Natera used misleading advertising to promote its Signatera test over Guardant's Reveal test, leading to a misinformed preference among patients and healthcare professionals[1]. Guardant accused Natera of unfairly portraying their test methodology as lacking, compared to Natera's purportedly superior technique[2]. The verdict was a significant triumph for Guardant, underscoring the importance of truthful advertising in the field of cancer diagnostics, although Natera has indicated plans to appeal the decision[1].
