What is the status of abandoned applications as prior art?
Abandoned applications can serve as prior art under certain conditions:
- If the abandoned application was previously published under 35 U.S.C. 122(b), it’s considered prior art as of its publication date under pre-AIA 35 U.S.C. 102(a) and 102(b) and 35 U.S.C. 102(a)(1).
- The MPEP states: “If an abandoned application was previously published under 35 U.S.C. 122(b), that patent application publication is available as prior art under pre-AIA 35 U.S.C. 102(a) and 102(b) and 35 U.S.C. 102(a)(1) as of its patent application publication date.”
- Unpublished abandoned applications may become prior art if they are identified or claimed in certain published documents, as per 37 CFR 1.14(a)(1)(iv).
