Where can I find guidance on the former inter partes reexamination practice?

Guidance on the former inter partes reexamination practice can be found in two main sources:

• Revision 7 of the 8th Edition of the MPEP
• The Federal Register notice titled “Revision of Standard for Granting an Inter Partes Reexamination Request,” published on September 23, 2011

As stated in MPEP 2611, “Guidance on the former practice is available in revision 7 of the 8th Edition of the MPEP and in Revision of Standard for Granting an Inter Partes Reexamination Request, 76 FR 59055 (September 23, 2011).” These resources provide detailed information on how inter partes reexamination requests were handled before the practice was discontinued.
