Can I still file a request for inter partes reexamination?
No, requests for inter partes reexamination are no longer accepted. According to MPEP 2631, “No requests for inter partes reexamination may be filed on or after September 16, 2012.” This change was part of the America Invents Act (AIA) which replaced inter partes reexamination with inter partes review.
For information on the former practice of inter partes reexamination, you can refer to the 9th Edition of the MPEP. However, it’s important to note that this information is now primarily of historical interest.
