US SB2455

Creates an administrative subpoena process allowing copyright owners to compel AI developers to disclose which copyrighted works were used to train generative AI models

Copyright owners must file a sworn declaration with a U.S. district court clerk stating good faith belief their works were used in AI training and that records will only be used to protect their rights

AI developers must expeditiously comply with subpoenas by providing copies of training materials or records sufficient to identify the copyrighted works used

Establishes a rebuttable presumption that developers copied the copyrighted work if they fail to comply with a valid subpoena

Includes confidentiality requirements preventing copyright owners from disclosing obtained records without authorization, and sanctions for bad faith subpoena requests under Federal Rule of Civil Procedure 11(c)
