Blow to AI, Clarity for Humans: Key Insights from the DABUS Rulings

The August 2019 announcement that two patent applications had been filed naming an artificial intelligence (AI) algorithm as an inventor in the United States and a dozen other countries was regarded as disruptive and profound at the time. It was one of the hot topics in patent law during those last few months before the pandemic. But since then, given all the other crazy and disorienting stuff that has happened in the world, we have become desensitized to the question, even if it is just as radical and important today. To be sure, the U.S. Court of Appeals for the Federal Circuit’s August 5 ruling that an “inventor” must, under the Patent Act, always be a human being, would seem to definitively resolve the question. As a matter of existing and clearly settled law, Stephen Thaler’s AI machine, DABUS, cannot be a named inventor on his applications for a fractal-shaped beverage container and a neural flame, like we always thought in the Before Times. It’s time to relegate this parlor-game discussion to the same recycle bin as Beeple’s non-fungible token (NFT), The Tiger King, and so many other viral distractions. Or, perhaps, not so fast.

Justice Gorsuch Champions Patent Rights in Recent Dissent

In an energetic dissent in Thryv, Inc. v. Click-to-Call Tech., LP, 590 U.S. __ (Apr. 20, 2020), U.S. Supreme Court Justice Neil Gorsuch provides a compelling defense of patent rights, and he champions a patent owner’s ability to obtain judicial review of certain threshold administrative decisions from the Patent Trial and Appeal Board (PTAB). But while Justice Gorsuch’s insightful analysis is receiving accolades from many in the patent community, it failed to garner any support among his Supreme Court colleagues, save for one, Justice Sotomayor.

Inequitable Conduct Ruling Gives Pleading Rules Real Teeth

Dr. Chris Mammen On August 4, 2009, the Federal Circuit decided Exergen Corp. v. Wal-Mart Stores, Inc., et al., Case Nos. 2006-1491, 2007-1180 (Fed. Cir. 2009). In a post to this blog several months ago, I argued that Congress, the Supreme Court or the Federal Circuit should reform the doctrine of inequitable conduct this year, to rein in the resurgent…

SCOTUS Will Not Decide Inequitable Conduct

Today, the Supreme Court denied certiorari in Aventis v. Amphastar (Docket No. 08-937). Inequitable conduct was the sole issue presented in the cert petition, which Aventis filed on January 23, 2009. According to the procedural summary in Aventis’ cert petition, the Federal Circuit held the patent on Aventis’ $2 billion-per-year drug to be unenforceable due to inequitable conduct because of…

A Call to Reform Inequitable Conduct This Year

Dr. Chris Mammen focuses his practice on patent and related intellectual property litigation and appeals. Twenty years ago, in the 1988 Burlington case, the Federal Circuit expressed its displeasure with the frequent assertion of the inequitable conduct defense in patent litigation, famously calling it a “plague.” Later that year, in the en banc portion of the Kingsdown case, the Federal…
