What is the purpose of ex parte reexamination?
The purpose of ex parte reexamination is to provide a mechanism for the USPTO to review the validity of an issued patent. According to MPEP 2209, “Ex parte reexamination is a patent office proceeding which provides a complete reexamination of the patent claims on the basis of prior art patents and printed publications.” This process allows for the correction of errors in patent claims and can help strengthen the overall patent system by ensuring the validity of issued patents.
