Why it matters

The U.S. Patent and Trademark Office extended its Artificial Intelligence Search Automated Pilot Program on April 17, 2026, pushing the petition deadline from April 20 to June 1, or until each of its Technology Centers reaches 400 granted applications. The program offers eligible applicants an automated, AI-assisted prior art search before substantive examination begins. Applicants who participate receive an Automated Search Results Notice listing up to 10 ranked references pulled from domestic and international patent databases. The notice is informational only and requires no response. To qualify, applicants must file original, noncontinuing, nonprovisional utility applications electronically through Patent Center. The USPTO waived petition fees in March and raised program capacity to 3,200 applications to encourage participation.

As of April 16, the program had received only 169 petitions with 76 granted. The extension timeline and specific metrics for each Technology Center remain subject to uptake. The USPTO has not disclosed whether additional incentives or modifications are planned if participation continues to lag.

Patent prosecutors should monitor this program as a potential tool for early prior art visibility, which can reshape prosecution strategy months before traditional USPTO searches occur. The low uptake despite fee waivers suggests many practitioners remain skeptical of AI-assisted searching or unfamiliar with the pilot. Attorneys handling high-volume prosecution portfolios may want to test the program on select applications to evaluate the quality and utility of the automated results before the June 1 deadline.
