Yes, each separate oath or declaration by an inventor should be complete in itself. The MPEP clearly states: “Each separate oath or declaration by an inventor should be complete in itself.” This guideline ensures that each inventor’s oath or declaration can stand alone and provide all necessary information without relying on other documents. This is particularly important for applications filed on or after September 16, 2012, where joint inventors may execute separate oaths or declarations.
