What happens if a new inventor is identified in a CPA without filing a proper request?

If a new inventor is identified in a Continued Prosecution Application (CPA) without filing a proper request, it can lead to inventorship issues. The MPEP ¶ 2.33 states:

It is noted that [1] identified as a named inventor in the Continued Prosecution Application (CPA) filed under 37 CFR 1.53(d) on [2], but no request under 37 CFR 1.48, as is required, was filed to correct the inventorship.

This means that simply naming a new inventor in the CPA filing documents is not sufficient. Without a proper request under 37 CFR 1.48, the inventorship will remain the same as in the prior application, potentially leading to complications in the patent prosecution process.
