Supreme Court Declines CareDx Appeal in Natera Ad Dispute
The U.S. Supreme Court has rejected CareDx's appeal in its false-advertising clash with genetic testing rival Natera, leaving a lower court ruling intact.
The U.S. Supreme Court has declined to hear an appeal from CareDx in its ongoing legal battle with Natera, Inc. over false-advertising claims, allowing a lower court's decision to stand. The move closes a significant avenue of relief for CareDx, which had sought the nation's highest court as a final recourse in the dispute.
The case centers on allegations of misleading marketing in the competitive genetic and molecular diagnostics space, where both CareDx and Natera operate transplant-monitoring and oncology testing products. False-advertising litigation in high-stakes medical technology markets carries particular weight, as the claims made about diagnostic accuracy and clinical utility can directly influence hospital procurement decisions and physician adoption.

By refusing to take up the case, the Supreme Court lets stand whatever ruling the lower court issued — a procedurally routine outcome given that the Court accepts only a small fraction of petitions, but one with real competitive consequences for CareDx.

For Natera, the development represents a measure of legal vindication and removes a layer of uncertainty that had been hanging over the company. Investors in both firms will now reassess the competitive landscape, with Natera's NTRA shares potentially benefiting from reduced litigation risk while CareDx must determine its next strategic and legal steps.
