Several major U.S. patent litigation venues have issued rules addressing generative artificial intelligence (AI) usage in legal filings. The Eastern District of Texas amended its local Rule CV-11 effective December 1, 2025, extending responsibility for accuracy of AI-assisted documents to all litigants. Magistrate Judge John D. Love requires filings in his court to include a “Certificate of Generative Artificial Intelligence Usage” detailing AI use, the tool involved, and verification of content accuracy. Judge Marcia A. Crone issued an order requiring a similar certificate and an additional certification that AI use did not disclose confidential or privileged information to unauthorized parties.

In the Western District of Texas, Judge Ernest Gonzalez mandates that pleadings involving generative AI include certification identifying the AI tool used and confirming independent verification of the factual and legal assertions as well as the nondisclosure of confidential or privileged information. In the Northern District of California, multiple magistrate judges require disclosure of AI-generated text in document titles or notices and maintenance of records sufficient to identify AI-generated content. These judges also emphasize counsel’s duty under Federal Rule of Civil Procedure 11 to verify the accuracy of such content. No districtwide AI rule exists in California districts; however, judge-specific standing orders impose detailed obligations for AI disclosure, content verification, and recordkeeping.
