SUPPLEMENTARY INFORMATION:

  1. Background

    The Drug Price Competition and Patent Term Restoration Act of 1984 (Pub. L. 98-417) and the Generic Animal Drug and Patent Term Restoration Act (Pub. L. 100-670) generally provide that a patent may be extended for a period of up to 5 years so long as the patented item (human drug product, animal drug product, medical device, food additive, or color additive) was subject to regulatory review by FDA before the item was marketed. Under these acts, a product's regulatory review period forms the basis for determining the amount of extension an applicant may receive.

    A regulatory review period consists of two periods of time: A testing phase and an approval phase. For medical devices, the testing phase begins with a clinical investigation of the device and runs until the approval phase begins. The approval phase starts with the initial submission of an application to market the device and continues until permission to market the device is granted. Although only a portion of a regulatory review period may count toward the actual amount of extension that the Director of USPTO may award (half the testing phase must be subtracted as well as any time that may have occurred before the patent was issued), FDA's determination of the length of a regulatory review period for a medical device will include all of the testing phase and approval phase as specified in 35 U.S.C. 156(g)(3)(B).

    FDA has approved for marketing the medical device ZILVER PTX DRUG ELUTING PERIPHERAL STENT. ZILVER PTX DRUG ELUTING PERIPHERAL STENT is indicated for improving luminal diameter for the treatment of de novo or restenotic symptomatic lesions in native vascular disease of the above-the-knee femoropopliteal arteries having reference vessel diameters from 4 millimeters (mm) to 9 mm and total lesion lengths up to 140 mm per limb and 280 mm per patient. Subsequent to this approval, the USPTO received a patent term restoration application for ZILVER PTX DRUG ELUTING PERIPHERAL STENT (U.S. Patent No. 6,299,604) from Cook Medical Technologies, LLC, and the USPTO requested FDA's assistance in determining this patent's eligibility for patent term restoration. In a letter dated March 25, 2014, FDA advised the USPTO that this medical device had undergone a regulatory review period and that the approval of ZILVER PTX DRUG ELUTING PERIPHERAL STENT represented the first permitted commercial marketing or use of the product. Thereafter, the USPTO requested that FDA determine the product's regulatory review period.

  2. Determination of Regulatory Review Period

    FDA has determined that the applicable regulatory review period for ZILVER PTX DRUG ELUTING PERIPHERAL STENT is 3,075 days. Of this time, 2,180 days occurred during the testing phase of the regulatory review period, while 895 days occurred during the approval phase. These periods of time were derived from the following dates:

    1. The date an exemption under section 520(g) of the Federal Food, Drug, and Cosmetic Act (the FD&C Act) (21 U.S.C. 360j(g)) involving this device became effective: June 16, 2004. FDA has verified the applicant's claim that the date the investigational device exemption (IDE) required under section 520(g) of the FD&C Act for human tests to begin became effective was June 16, 2004.

    2. The date an application was initially submitted with respect to the device under section 515 of the FD&C Act (21 U.S.C. 360e): June 4, 2010. FDA has verified the applicant's claim that the premarket approval application (PMA) for ZILVER PTX DRUG ELUTING PERIPHERAL STENT (PMA P100022) was initially submitted June 4, 2010.

    3. The date the application was approved: November 14, 2012. FDA has verified the applicant's claim that PMA P100022 was approved on November 14, 2012.

    This determination of the regulatory review period establishes the maximum potential length of a patent extension. However, the USPTO applies several statutory limitations in its calculations of the actual period for patent extension. In its application for patent extension, this applicant seeks 1,826 days of patent term extension.

  3. Petitions

    Anyone with knowledge that any of the dates as published are incorrect may submit either electronic or written comments and ask for a redetermination (see DATES). Furthermore, any interested person may petition FDA for a determination regarding whether the applicant for extension acted with due diligence during the regulatory review period. To meet its burden, the petition must be timely (see DATES) and contain sufficient facts to merit an FDA investigation. (See H. Rept. 857, part 1, 98th Cong., 2d sess., pp. 41-42, 1984.) Petitions should be in the format specified in 21 CFR 10.30.

    Submit petitions electronically to http://www.regulations.gov at Docket No. FDA-2013-S-0610. Submit written petitions (two copies are required) to the Division of Dockets Management (HFA-305), Food and Drug Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

    Dated: June 13, 2016.
