What types of national applications can be filed under U.S. patent laws?

Under U.S. patent laws, several types of national applications can be filed. The MPEP 201.01 states:

‘National applications include original (nonprovisional), reissue, and reexamination applications (including supplemental examination proceedings). The original application includes continuation, divisional, and continuation-in-part applications. National applications may be filed under 35 U.S.C. 111(a) or (b), 161, or 171.’

To break this down:

• Original (nonprovisional) applications: Standard utility patent applications
• Reissue applications: To correct errors in already granted patents
• Reexamination applications: To request the USPTO to reexamine an existing patent
• Continuation applications: Based on an earlier-filed application
• Divisional applications: Derived from a parent application to pursue different inventions
• Continuation-in-part applications: Adding new matter to a parent application
• Design patent applications (under 35 U.S.C. 171)
• Plant patent applications (under 35 U.S.C. 161)
