# 5.19 Export of technical data.

(a) Under regulations (15 CFR 734.3(b)(1)(v)) established by the Department of Commerce, a license is not required in any case to file a patent application or part thereof in a foreign country if the foreign filing is in accordance with the regulations (§§ 5.11 through 5.25) of the U.S. Patent and Trademark Office.

(b) An export license is not required for data contained in a patent application prepared wholly from foreign-origin technical data where such application is being sent to the foreign inventor to be executed and returned to the United States for subsequent filing in the U.S. Patent and Trademark Office (15 CFR 734.10(a)).
