What is the difference between correcting inventorship in inter partes and ex parte reexamination?

There is no difference in the process of correcting inventorship between inter partes and ex parte reexamination proceedings. According to MPEP § 2666.03:

“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.”

This means that regardless of whether the reexamination is inter partes or ex parte, the procedure for correcting inventorship remains consistent. Both types of proceedings follow the guidelines outlined in MPEP § 2250.02.
