How does MPEP 201.01 define a national application?

MPEP 201.01 provides a clear definition of a national application in the context of U.S. patent law. According to MPEP 201.01:

‘A national application is one that was filed in the United States Patent and Trademark Office (USPTO) under 35 U.S.C. 111(a), an application which entered the national stage from an international application after compliance with 35 U.S.C. 371, or a reissue application filed under 35 U.S.C. 251.’

This definition encompasses three main categories:

1. Applications filed directly with the USPTO under 35 U.S.C. 111(a)
2. International applications that have entered the national stage in the U.S. after complying with 35 U.S.C. 371
3. Reissue applications filed under 35 U.S.C. 251

Understanding this definition is crucial for patent applicants and practitioners to determine the appropriate filing procedures and requirements for their inventions.
