Tillis Bill Tries to Fix Section 101

Posted on August 8, 2022 by Warren Woessner

This recently introduced bill would replace section 101 with a lot of text. The commentators are all commentating, but I have yet to read whether or not the “outlaw” status of claims to diagnostic methods—led by varying interpretations of Mayo v. Prometheus—has been clearly lifted by this bill. Here are the relevant parts, at least setting up the discussion on this point.

CareDx v. Natera – The Broad Road to Patent Ineligibility

Posted on July 21, 2022 by Warren Woessner

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

Posted on June 22, 2022 by Warren Woessner

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.
