USPTO Issues Revised 2025 Inventorship Guidance For AI-Assisted Inventions

The U.S. Patent and Trademark Office (USPTO) issued Revised Inventorship Guidance for AI-Assisted Inventions (Updated Guidance), providing a more streamlined and traditional framework for determining inventorship when AI tools are used in the inventive process. Effective November 28, 2025, the Updated Guidance rescinds previous USPTO guidance and reaffirms that inventorship remains grounded solely in human contribution and the longstanding conception standard for individual inventorship.

While the Updated Guidance does not modify any of the underlying legal doctrines for determining inventorship, it clarifies how AI-assisted innovation should be evaluated under existing doctrine and signals several areas where practitioners should exercise heightened scrutiny.
