CareDx Announces District Court Reverses Jury Decision in Patent Infringement Case Overturning Prior $96 Million Verdict

February 25, 2025 at 07:05 AM EST

All Patent Claims Asserted Against CareDx are Found to Be Invalid

CareDx, Inc. (Nasdaq: CDNA) – The Transplant Company™ focused on the discovery, development, and commercialization of clinically differentiated, high-value healthcare solutions for transplant patients and caregivers – today announced that the District Court overturned the jury verdict in patent litigation brought by a competitor.

The District Court ruled that the patents asserted against CareDx are invalid. The Court reached this determination because the patents failed to describe the claimed invention in sufficient detail. CareDx believes that the Court's decision brings this lawsuit to its rightful legal outcome and is a win for transplant patients.

CareDx developed the industry’s first donor-derived cell-free DNA assay, AlloSure®, for identifying organ rejection in transplant patients. AlloSure was first commercially introduced in 2017 for kidney transplant patients and subsequently was validated for heart and lung transplant patients.

If the plaintiff, Natera, appeals, CareDx will continue to vigorously defend its technology.

In addition, the patent that is the basis of the $96 million verdict is also subject to a pending ex parte reexamination before the United States Patent and Trademark Office (“PTO”). On February 14, 2025, a PTO examiner issued a non-final Office action rejecting the claims CareDx was found to have infringed in the litigation.
