On April 20, 2023, the United States Patent and Trademark Office (USPTO) announced several proposed rule changes that would have an impact on patent applicants, patent holders, and patent challengers. A common thread running through several of the rule changes is the requirement of increased disclosure from litigating parties, including disclosures of related parties, ownership interests, and all settlement agreements (and any related or collateral agreements) between the parties.
