• Decision has No Impact on CareDx’s Ability to Continue Providing AlloSure® nor Commitment to Transplant Innovation
• CareDx Believes Decision Applies Equally to Other Diagnostics Patents, including Natera’s Transplant Diagnostic Patents

BRISBANE, Calif. / Oct 03, 2023 / Business Wire / 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 – acknowledges the Supreme Court’s decision not to review the Federal Circuit’s decision on the patent eligibility of three Stanford-licensed patents. CareDx notes the decision does not impact the Company’s ability to continue providing AlloSure® donor-derived cell-free DNA (dd-cfDNA).

While CareDx respectfully disagrees with the Supreme Court’s decision, the case law applies equally to other transplant diagnostics patents, including Natera’s, and CareDx has filed a motion to invalidate Natera’s patents on these same grounds.

CareDx remains committed to improving transplant patient outcomes by providing innovative and intelligent solutions throughout the entire patient journey. It is proud of the proprietary nature of its ground-breaking quantification method spurred by years of research and innovation in the field of transplant diagnostics that led to success where others failed.
