AI Deemed a Tool Not an Inventor, Under Updated USPTO Policy

New guidelines clarifying how artificial intelligence (AI) should be treated in patent applications have been issued by the United States Patent and Trademark Office (USPTO). The updated framework was released on Friday, reaffirming that AI systems cannot be recognised as inventors under US patent law and must be treated only as tools used by human creators.

According to the notification, AI-assisted inventions will no longer be evaluated under any separate or modified standard. Instead, they will be examined under the same criteria used for traditional inventions. It has been emphasised that only human beings who conceive the core inventive idea may be named as inventors. AI systems, including generative AI models, have been described as tools similar to laboratory equipment, software, or research databases.

It was stated by the USPTO that AI may generate suggestions, drafts, or technical inputs, but such contributions do not qualify the technology for inventorship. The responsibility for conception, decision-making, and technical definition of an invention must remain with a human applicant. The burden has also been placed on inventors to demonstrate that human creativity led to the invention, even when AI-assisted processes were used.

The earlier guidance published in February 2024, which had examined the possibility of applying human joint-inventor standards to AI-related inventions, has been rescinded. The office clarified that the “Pannu factors” — the long-standing criteria for determining human co-inventorship — do not apply when non-human tools are involved. The agency reiterated that inventorship under US law is limited strictly to natural persons, a principle reinforced by earlier federal court rulings that rejected AI inventorship claims.

Patent examiners have been instructed that the role of AI in drafting or ideation should not be evaluated. Instead, assessments will focus solely on whether a human inventor conceived the invention’s technical details and whether those details were sufficiently disclosed in the patent application.

While the use of AI tools in the invention process is not restricted, the USPTO underlined that generic use of AI for data processing, brainstorming, or documentation does not automatically translate to inventorship or patent eligibility. Applicants must clearly establish the human contribution behind any claimed invention.

The clarification has been issued as AI increasingly becomes part of research, design, and product development across industries. Although advancements in AI-generated content continue to spark global debate, the US has maintained that inventorship rights must remain with humans.
