How can I obtain copies of Office actions in inter partes reexamination proceedings?

This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Copies of Office actions in inter partes reexamination proceedings can be obtained through the USPTO’s Public PAIR system. The MPEP states:

Copies of Office actions may be obtained by accessing Public PAIR at the Office’s website www.uspto.gov.

Public PAIR (Patent Application Information Retrieval) is an online portal that provides access to patent application status and documents. Additionally, in inter partes reexamination proceedings, a copy of each Office action is mailed to the third party requester using a transmittal form PTOL-2070.
