What is a divisional application under 37 CFR 1.53(b)?

A divisional application under 37 CFR 1.53(b) is a type of continuation application that is filed to pursue a distinct invention that was disclosed but not claimed in a prior nonprovisional application. According to the MPEP:

‘A divisional application is often filed as a result of a restriction requirement made by the examiner.’

Divisional applications allow inventors to protect multiple inventions disclosed in a single parent application by filing separate applications for each invention.
