What is the purpose of listing prior art in an inter partes reexamination?
The purpose of listing prior art in an inter partes reexamination is to ensure that all relevant prior art is considered during the reexamination process. According to MPEP 2657:
“The reexamination request must provide a list of all prior art patents or printed publications (other than those already cited in the patent) that are relied upon to establish a substantial new question of patentability.”
This listing helps the examiner and all parties involved to have a comprehensive view of the prior art that may affect the patentability of the claims under reexamination.
