False Advertising Lawsuit Against Natera is Set to Go to Trial

CareDx Plans to Appeal Recent Ruling in Patent Case

SOUTH SAN FRANCISCO, Calif., Sept. 28, 2021 (GLOBE NEWSWIRE) -- CareDx, Inc. (Nasdaq: CDNA), a leading precision medicine company focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions for transplant patients and caregivers, today announced that in a hearing today, the District Court confirmed that the false advertising case against Natera will proceed to trial. The current trial date is October 25, 2021.

CareDx also issued the following statement regarding its patent infringement case against Natera, which is unrelated to the false advertising case.

CareDx respectfully disagrees with the courts ruling and intends to appeal. While the trial courts patent ineligibility finding for these three patents has no impact on our ability to continue providing AlloSure, we continue to believe Natera and Eurofins Viracor are infringing these patents. We have deep respect for our partners at Stanford University, whose ground-breaking innovation enabled non-invasive organ transplant monitoring, and we are proud to defend the patents that resulted from their ingenuity. As always, CareDx remains committed to improving transplant patient outcomes by providing innovative and intelligent solutions throughout the entire patient journey.

CareDx has brought claims of patent infringement against Natera and Eurofins Viracor in the United States District Court for the State of Delaware. CareDxs claims relate to three patents, exclusively licensed to CareDx from Stanford University, which cover methods for non-invasive monitoring of organ transplant rejection through cell-free DNA analysis. Notably, earlier in this case, the Magistrate Judge agreed with CareDx on the patent eligibility issue. CareDx plans to appeal the ruling.
