USPTO Extends AI Search Pilot Through June to Evaluate Effectiveness

The U.S. Patent and Trademark Office will keep its AI-based search pilot program running until June 1 to gather more data on how well the tool performs.

The program, which launched last year, lets patent applicants and examiners use artificial intelligence to search for prior art. The extended timeline gives the USPTO additional time to assess whether the tool meets its goals before deciding on permanent implementation.

Patent professionals and trademark applicants have been using the system to locate existing patents and trademarks during the examination process. Prior art searches are central to determining whether a new invention or mark qualifies for protection.

The pilot extension suggests the USPTO found enough promise in the initial results to warrant continued testing rather than immediate rollout or discontinuation. The agency has not yet disclosed specific metrics on search accuracy, time savings, or user adoption rates.

For legal professionals working in intellectual property, the program represents a shift toward automated tools for routine patent office tasks. Patent agents and in-house counsel managing large portfolios may see workflow changes depending on the pilot's final outcome.

The June deadline gives the USPTO roughly two months to compile findings before announcing next steps. Patent law firms and corporate IP departments tracking the pilot should expect guidance by mid-summer.
