Question:
Who is barred from filing a request for ex parte reexamination of a patent?
Answer:
“Any person” may file a request for ex parte reexamination of a patent, unless prohibited by AIA 35 U.S.C. 315(e)(1) or 35 U.S.C. 325(e)(1). Accordingly, there are no types of “persons” who are excluded from being able to seek reexamination.
- Corporations and/or governmental entities are included within the scope of the term “any person.”
- The only “person” who is barred from filing a request for ex parte reexamination of a patent is one who is barred from doing so by the estoppel provisions of AIA 35 U.S.C. 315(e)(1) or 35 U.S.C. 325(e)(1) based on inter partes review and post grant review, respectively, once the estoppel attaches.
