Under AIA 35 U.S.C. 102(a)(2), several types of U.S. patent documents can qualify as prior art. According to MPEP 2154.01(c), these include:
- U.S. patents
- U.S. patent application publications
- WIPO published applications
The MPEP states: “To qualify as prior art under AIA 35 U.S.C. 102(a)(2), the prior art U.S. patent, U.S. patent application publication, or WIPO published application (‘U.S. patent document’) must ‘name[ ] another inventor.’”
It’s important to note that these documents must also meet the “names another inventor” requirement and any other applicable criteria to be considered prior art under this section.
