Can a nonprovisional patent application be converted to a provisional application?

Yes, it is possible to convert a nonprovisional patent application to a provisional application under certain circumstances. The MPEP states:

Petitions to convert a nonprovisional application filed under 37 CFR 1.53(b) to a provisional application under 37 CFR 1.53(c) where the nonprovisional application is before the Office of Initial Patent Examination or where the nonprovisional application is before the Office of Patent Application Processing.

This conversion process is handled by the Director of Office of Patent Application Processing (OPAP). It’s important to note that this conversion is only possible if the application is still in the early stages of examination, specifically before it reaches the examining corps. Applicants might choose this conversion for various strategic reasons, such as extending the time for filing a full nonprovisional application or reassessing their patent strategy.
