Here’s the complete FAQ:

The MPEP 201.01 mentions several special types of national applications:

1. Provisional applications (35 U.S.C. 111(b))
2. Reissue applications (35 U.S.C. 251)
3. Design applications (35 U.S.C. 171)
4. Plant applications (35 U.S.C. 161)

These applications have specific requirements and purposes. For example, provisional applications provide a way to establish an early effective filing date, while reissue applications allow for the correction of errors in issued patents. Design applications protect ornamental designs, and plant applications are for new varieties of plants.
