The USPTO issued guidance on February 6, 2024 that clarified existing rules and policies and discussed how to apply them when AI is used in the drafting of submissions to the Patent Trial and Appeal Board (PTAB) and Trademark Trial and Appeal Board (TTAB). As a follow up, the USPTO has now published additional guidance in the Federal Register on some important issues that patent and trademark professionals, innovators, and entrepreneurs must navigate while using artificial intelligence (AI) in matters before the USPTO. The guidance recognizes that practitioners use AI to prepare and prosecute patent and trademark applications. It reminds individuals involved in proceedings before the USPTO of the pertinent rules and policies, identifies some risks associated with the use of AI, and provides suggestions to mitigate those risks. It states that while the USPTO is committed to maximizing AI’s benefits, the USPTO recognizes the need, through technical mitigations and human governance, to cabin the risks arising from the use of AI in practice before the USPTO. The USPTO has determined that existing rules protect the USPTO’s ecosystem against such potential perils and thus no new rules are currently being proposed.Continue Reading USPTO Issues Additional Guidance on Use of AI Tools in Connection with USPTO Matters
