Rader’s Ruminations – Patent Eligibility, Part 1: The Judge-Made ‘Exceptions’ are Both Unnecessary and Misconstrued

In supreme irony, the U.S. Supreme Court lists the three exceptions to statutory patent eligibility in Chakrabarty, Diamond v. Chakrabarty, 447 U.S. 303 (1980) — the case most famous for the observation that Thomas Jefferson’s statutory language from the 1793 Act (still in place today) covers “anything under the sun made by man.” Id. at 309. While construing Jefferson’s “broad” statutory language in 35 U.S.C. 101 with “wide scope,” the Court noted: “The laws of nature, physical phenomena, and abstract ideas have been held not patentable.” Id. The Court tries to support this listing with a string citation to several cases — each standing for something different than an exception from statutory language. Still, to ensure clarity, the Court gives examples: “a new mineral discovered in the earth or a new plant found in the wild is not patentable subject matter.” Likewise, Einstein could not patent his celebrated law that E=mc2, nor could Newton have patented the law of gravity.”  Id. So far so good, but this classic example of the Court trying to sound informed and competent out of its comfort zone reemerges 30 years later to replace (and effectively overrule) the statutory rule that governed for over 200 years and remains in Title 35.

Supreme Court Again Denies Inventor’s Bid to End Alice/Mayo

On Monday, the United States Supreme Court denied inventor Jeffrey Killian’s petition for a rehearing in his case asking the Court to provide clear guidance on – or else throw out – the Alice/Mayo test for patent eligibility. The Supreme Court denied Killian’s original petition in early October, but Killian filed a request for rehearing several weeks later. Killian first filed a petition for writ of certiorari to the Supreme Court in April, after the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed the Patent Trial and Appeal Board’s (PTAB)’s ruling rejecting claims of his U.S. Patent Application No. 14/450,042 under Section 101.

What the Patent Eligibility Restoration Act Means for Artificial Intelligence Inventions

PERA is no doubt an ambitious bill. In terms of its design, the proposed legislation attempts to deal with each of the Supreme Court’s decisions in Alice, Mayo and Myriad, plus all of their progeny applications thereafter engendered by the Federal Circuit, the Patent Trial and Appeal Board (PTAB), all the way down to the U.S. Patent and Trademark Office (USPTO) examining corp. In a nutshell, the bill, if passed, would return us to a time when Bilski was the law of the land, which will no doubt be welcomed by many innovators.

Blow to Computer-Implemented Inventions: Canadian Court of Appeal Strikes Down the Subject-Matter Eligibility Test

The Canadian Federal Court of Appeal (FCA), in Attorney General of Canada v. Benjamin Moore & Co. [2023 FCA 168], a 3-0 decision, recently set aside the test on subject matter eligibility of computer-implemented inventions laid down by the Federal Court [2022 FC 923] last year. Acclaimed by patent professionals as a “favorable decision for Canadian applicants who have computer-implemented inventions,” the test had, for the first time, presented a declaratory relief and guidance for examining subject-matter eligibility, particularly for computer-implemented inventions. While the setting aside of the test relays subject matter assessments back to the procedure set by the Commissioner of Patents (Canada), the FCA clarified some key areas associated with the claim construction and patentability analysis.

Passing PERA Assures Patent Eligibility for All Useful Inventions

Confusion and misunderstanding among some independent inventors might slow or stall progress of the excellent eligibility reform bill recently introduced by Senators Chris Coons (D-DE) and Thom Tillis (R-NC). Titled the Patent Eligibility Restoration Act (PERA), the legislation would overturn Supreme Court and Federal Circuit decisions that scrambled settled law, excluding many worthy classes of inventions, such as medical diagnostic methods and advanced computer applications.
