Section Summary:

This question and answer comes from section 140 of the MPEP.  The following is a brief summary of section 140.

140 Foreign Filing Licenses

This section covers both expedited foreign filing licenses and retroactive licenses. Essentially, if an inventor files a patent application in the U.S., he or she may not file the same application in a foreign country prior to the passing of six months without first obtaining a foreign filing license. If the inventor files in a foreign country before the 6 month waiting period has passed without getting a license first, he or she must immediately file for a retroactive license.
