The Federal Circuit's 2022 decision in Thaler v. Vidal seemed to settle a fundamental question: only natural persons can be inventors under U.S. patent law. But, the bigger near-term question has always been about human-AI collaboration - and what level of human contribution is sufficient to qualify as inventive. Director Kathi Vidal implemented a team-based framework that allowed patenting if the human made a "more than insignificant contribution" to the invention. This approach basically asked whether the human had done enough to be considered a joint joint inventor (alongside the AI). While that approach had some conceptual problems (permitting patenting without complete human inventorship), it - at least - set a standard for the agency to consider.
In a November 2025 guidance, new USPTO Director John Squires has rejected the Vidal approach and instead established a "don't ask, don't tell" policy for AI-assisted inventions creates a presumption of human inventorship so long as any natural person is willing to sign the oath. For all practical purposes, this approach is also a repudiation of Thaler, so long as the patent applicant is able to find a human close to the invention willing to self-identify as the inventor. The system now effectively rewards an old habit in invention culture: when attribution becomes optional and unverifiable, someone will always be willing to step forward and claim the mantle of inventor. In a chapter I wrote a few years ago examining corporate invention, I observed: "It is easy to identify a human with some relation to the product or innovation and prop-up that human as the inventor."
