What information can an examiner request about related patent applications?
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.
An examiner can request information about related patent applications during the examination process. According to MPEP 704.11(a), an examiner may reasonably require:
“(G) Identification of pending or abandoned applications filed by at least one of the inventors or assigned to the same assignee as the current application that disclose similar subject matter that are not otherwise identified in the current application.”
This information helps the examiner to:
- Identify potential double patenting issues
- Understand the broader context of the inventor’s work
- Ensure consistent examination across related applications
It’s important to note that for applications filed before June 8, 1995, there are specific confidentiality requirements that must be observed, as outlined in the same MPEP section.
