The USPTO on April 21, 2023 proposed a variety of changes to the pre-institution requirements and briefing process for post-grant proceedings, including both IPRs and PGRs. Among the proposed changes are broad amendments to the discretionary denial frameworks, which are intended to provide clarity, curb abusive litigation tactics, and generally align procedure with the objectives of the AIA. The deadline for submitting comments and suggestions related to these rules is June 20, 2023.
