What is the significance of the In re Monks case for patent reference dates?

The In re Monks case is significant in establishing the general rule for when a foreign patent becomes available as a reference. MPEP 2126.01 cites this case:

“In re Monks, 588 F.2d 308, 200 USPQ 129 (CCPA 1978).” (MPEP 2126.01)

This case affirmed the principle that the date a foreign patent becomes available as a reference is generally the date when the patent becomes enforceable, which is typically when the sovereign formally grants patent rights to the applicant. This ruling provides a clear standard for determining the effective date of foreign patents as prior art in U.S. patent examination.
