What happens to other USPTO proceedings during an interference?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

When an interference is initiated, other proceedings within the USPTO for the involved file are generally suspended. The MPEP 2307 clearly states:

“Other proceedings for the involved file within the Office are suspended except as the Board may order.”

This suspension ensures that the Board has exclusive control over the involved file during the interference. However, the Board has the discretion to allow certain proceedings to continue if deemed necessary. This policy helps maintain consistency and prevents potential conflicts between different USPTO proceedings involving the same patent or application.
