US Supreme Court rebuffs CareDx patent lawsuit over organ-rejection tests

WASHINGTON: CareDx filed a lawsuit against the US Supreme Court on Monday over organ rejection tests conducted by Natera and Eurofins Viracor, and the jury rejected another request to reexamine the contested patent eligibility issue.

The judges denied CareDx’s appeal after a lower court ruled invalidating patents that the Brisbane, California-based business had claimed its competitors in the clinical diagnostics industry had violated. The judges made their decision public on the first day of their new nine-month expression.

In 2019, CareDx filed a lawsuit against Texas-based Natera and Viracor, two subsidiaries of Luxembourg’s Eurofins Scientific, alleging that they had violated patents relating to its AlloSure blood test, which monitors liver transplants. The patents, which CareDx obtains from Stanford University, deal with techniques for determining the DNA levels of an organ donor in the body of a transplant recipient in order to forecast whether their figure may dismiss the organ.

CareDx claimed that the competing Prospera exam from Natera and Viracor’s TRAC Kidney check were infringing on its trademark rights.

The inventions were declared invalid by the patent-focused US Court of Appeals for the Federal Circuit last year, upholding a national judge’s ruling from Delaware that they relate to the abound concept of natural events.

CareDx stated to the Supreme Court that it was” overdue” to address the patent registration matter, which the business claimed has been particularly challenging for medical tests manufacturers.

In the 2014 event Alice Corp. v. CLS Bank International, which helped establish a two-part eligibility test in addition to the 2012 decision on clinical patents, Mayo Collaborative Services. Prometheus Laboratories, the Supreme Court past addressed trademark eligibility. If an innovation involves an abound abstract thought, natural trend, or law of nature, and if so, whether it includes an clever concept that may make it legal, the test requires courts to determine this.

The standard, according to critics, has led to confusion over which inventions are legally protected and the cancellation of true patents in a variety of fields.

Despite the requests of the Federal Circuit and the previous two political administrations, whose 12 active judges asked the Supreme Court to take up the matter in 2019, the justices have rejected several appeals pertaining to patent enrollment.

In the Supreme Court’s order from Monday, Justice Brett Kavanaugh stated that he would have granted CareDx ‘ request.
