Courts are writing their own rules about generative AI, and in patent cases those rules differ sharply from judge to judge. This survey, current as of September 8, 2026, catalogs the generative-AI requirements in the venues where most patent infringement suits land: the Eastern and Western Districts of Texas, the Northern and Central Districts of California, the Northern District of Illinois, the District of New Jersey, and the District of Delaware and the U.S. International Trade Commission, where no AI-specific rules were identified. Only the Eastern District of Texas has a court-wide rule, making every litigant responsible for verifying AI-assisted filings. Elsewhere the obligations come from individual judges’ standing orders and vary widely, from restating the existing duty to verify what you sign to requiring a separate certificate naming the AI tool, confirmation that a human checked every citation, records of the prompts used, or disclosure of AI use in billing. Penalties include $500 per violation and having the filing struck.
