United States Patent and Trademark Office

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. While the proposed rule changes are subject to a public comment period, if implemented, they would (i) introduce several major changes to the process of challenging patents before the Patent Trial and Appeal Board (PTAB) and (ii.) significantly increase USPTO administrative fees.
