How is inventorship corrected in an inter partes reexamination proceeding?

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.

Correction of inventorship in an inter partes reexamination proceeding follows the same process as in an ex parte reexamination proceeding. The Manual of Patent Examining Procedure (MPEP) § 2666.03 states:

“Correction of inventorship in an inter partes reexamination proceeding is effected in the same manner that correction of inventorship in an ex parte reexamination proceeding is effected.”

For specific details on the process, the MPEP directs readers to MPEP § 2250.02, which outlines the procedure for both inter partes and ex parte reexamination proceedings.
