CareDx v. Natera – The Broad Road to Patent Ineligibility

In CareDx v Natera, Appeal No. 2022-1027, (Fed. Cir., July 18, 2022), a three judge panel of Judges Lourie, Bryson and Hughes, affirmed the district court’s finding that the claims of U. S. patent nos. 8703652, 9845497 and 10329607 are invalid for failing to survive the Alice/Mayo test for patent eligibility. I subtitled this post using Matthew 7:13-14: “Enter through the narrow gate. For wide is the gate and broad is the road, that leads to destruction.” The appeal to the Federal Circuit, which I wrote about on October 15, 2021, never got on the narrow road that leads to viable diagnostic claims. It may not have been possible to overcome the obstacles that blocked the road, but CareDx managed to hit them all, and ended up with three invalid patents on natural phenomena.

Novartis v. Accord Redux – Panel 2 Reverses Panel 1

To save me a lot of typing, please read my post of January 10, 2022, summarizing the first Panel’s holding in Novartis Pharmaceutical v Accord Healthcare, Inc., 21 F.4th 1362 (Fed. Cir., 2022). The panel in that decision was Judges Moore, O’Malley and Linn, with Moore dissenting. A brief summary of the holding was that the majority of the panel found that a negative limitation that was disclosed only by implication in the specification satisfied the written description requirement.  A slightly different Panel,  consisting of Judges Moore, Linn and Hughes granted rehearing.  The panel split, with Moore writing for the majority and Linn dissenting.

The Solicitor’s Holistic Approach to the Mayo/Alice Analysis in American Axle

This is not exactly breaking news, and other commentators have discussed it, but I think that the Solicitor General’s Amicus Brief urging the Supreme Court to grant cert. in American Axle v. Neapco Holdings, Appeal No. 20-891 (May 2022) contains language that would be helpful to any inventor faced with a ruling that an invention is not patent-eligible because it is an attempt to monopolize a natural law. If the facts of this case have become hazy, please re-read my posts of January 13th and 11th, 2021, on the proceedings below. American Axle petitioned for cert. after losing at the Fed. Cir. level and the Supreme Court asked the Solicitor General to provide her opinion on the question of “[w]hether claim 22 of petitioner’s patent, which claims a process for manufacturing an automobile driveshaft that simultaneously reduces two types of driveshaft variation, is patent eligible under Section 101.” The Solicitor General’s brief said that it should be patent eligible.
