Can I add or substitute inventors when filing a CPA for a design patent?

The MPEP ¶ 2.32 specifically addresses the process of deleting named inventors when filing a Continued Prosecution Application (CPA) for design patents. However, it does not explicitly mention adding or substituting inventors at the time of CPA filing.

If you need to add or substitute inventors, rather than just delete them, you should follow the general procedures for correction of inventorship outlined in 37 CFR 1.48. This regulation provides the requirements for adding, deleting, or substituting inventors in patent applications.

It’s advisable to consult with a patent attorney or contact the USPTO directly for guidance on the proper procedure for adding or substituting inventors when filing a CPA, as this may require additional documentation or fees beyond a simple deletion request.
