The document is a final decision regarding the application for patent term extension of U.S. Patent No. 4,600,706, filed by Arkion Life Sciences, Inc. The request for extension was based on the FDA's approval of a food additive, NSUREB (natamycin). However, both the USPTO and FDA determined that NSUREB does not represent the first permitted marketing or use of natamycin under applicable law. Consequently, the requests for extension and reconsideration were denied, and previously granted interim extensions were vacated.
