Can multiple inventors be deleted from a Continued Prosecution Application at once?

Yes, multiple inventors can be deleted from a Continued Prosecution Application (CPA) at once. The language in MPEP ¶ 2.32 supports this:

In bracket 1 insert the name or names of the inventor(s) requested to be deleted.

This indicates that the process allows for the deletion of one or more inventors simultaneously. When filing a CPA, applicants can submit a statement requesting the deletion of multiple named inventors who are not inventors of the invention being claimed in the new application.

However, it’s crucial to ensure that all remaining inventors are correctly named and that the inventorship accurately reflects those who contributed to the claimed invention. If the CPA has already been filed, remember that any subsequent inventorship changes must follow the procedures outlined in 37 CFR 1.48.
