When was the last day to file an inter partes reexamination request?

The last day to file an inter partes reexamination request was September 15, 2012. According to MPEP 2626:

“No requests for inter partes reexamination may be filed on or after September 16, 2012.”

This means that September 15, 2012, was the final day on which the USPTO accepted inter partes reexamination requests. After this date, the procedure was replaced by inter partes review as part of the changes implemented by the America Invents Act.
