What is the deadline for submitting an inventor’s oath or declaration in a patent application?
The deadline for submitting an inventor’s oath or declaration in a patent application filed on or after September 16, 2012, is the date on which the issue fee is paid. This is stated in MPEP 602.01(a):
For applications filed on or after September 16, 2012, the timing of the submission of the inventor’s oath or declaration has been liberalized. The inventor’s oath or declaration is no longer required to be submitted prior to the filing of the application. Rather, the inventor’s oath or declaration may be postponed until payment of the issue fee.
However, it’s important to note that while the oath or declaration can be submitted later, the application must still include the names of all inventors at the time of filing. If the oath or declaration is not submitted with the initial application, a substitute statement may be required.
