In CareDx v. Natera, an intriguing amicus transient was not too long ago filed by the Honorable Paul Michel (Ret.) and Professor John Duffy in assist of the patentee petitioners Stanford and CareDx. The transient advocates for the clarification of patent-eligibility legislation, and criticizes the Federal Circuit’s dealing with of the case. The submitting of the transient has seemingly prompted the Supreme Court docket to request a response from the accused infringers, after they initially waived their proper to take action. This transfer displays some significance of the arguments offered within the transient.  [Read the Brief]

In line with Michel and Duffy, the Federal Circuit’s resolution within the case ignored the textual content of the Patent Act and conflicts with Supreme Court docket precedent comparable to Diehr and Cochran v. Deener. They argue that the choice fails to acknowledge the distinction between patent eligibility (below § 101) and patentability (below §§ 102, 103, and 112). They additional criticize the choice for an unduly simplified description of the invention that leaves out vital particulars and for improper emphasis on “conventionality.”  The idea of “conventionality” is extra appropriately related to problems with novelty and nonobviousness, as regulated by §§ 102 and 103 respectively, reasonably than being a key criterion for patent eligibility below § 101.

The transient spends some period of time specializing in landmark patent circumstances comparable to Diehr and Cochrane v. Deener (whereas rejecting Flook) for instance how a course of might be patent eligible regardless of encompassing standard parts.  And, all through this argues that the Federal Circuit misunderstood the definition of “course of,” which below 35 U.S.C. § 100(b) is outlined to incorporate “a brand new use of a identified course of.” The transient contends that this definition permits patents on new purposes or enhancements of identified applied sciences, and that such enhancements ought to be presumed to be patent eligible.  However, the Federal Circuit’s eligibility standards of “conventionality” prohibits this interpretation regardless that not rooted within the Patent Act’s textual content or the Supreme Court docket’s precedent.

As with different latest eligibility briefs, this one additionally underscores a necessity to handle confusion and uncertainty surrounding patent eligibility, significantly in relation to biomedical and diagnostic patents.

Now that we’re nearly to June, the petition is unlikely to be determined earlier than the recess and as an alternative will probably be held-over till the autumn 2023 earlier than we get a choice on whether or not the court docket will grant certiorari.
