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.

The MPEP provides a convenient resource for finding patenting dates of foreign patents. As stated in MPEP 2126.01:

“Note that MPEP § 901.05 summarizes in tabular form dates of patenting for many foreign patents.” (MPEP 2126.01)

This tabular summary in MPEP § 901.05 can be a valuable reference for patent examiners, attorneys, and inventors when determining the effective date of foreign patents as prior art.
