SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for ZILVER PTX DRUG ELUTING PERIPHERAL STENT 
and is publishing this notice of that determination as required by law. 
FDA has made the determination because of the submission of 
applications by Boston Scientific Scimed, Inc., to the Director of the 
U.S. Patent and Trademark Office (USPTO), Department of Commerce, for 
the extension of patents which claim that medical device.

DATES: Anyone with knowledge that any of the dates as published (see 
the SUPPLEMENTARY INFORMATION section) are incorrect may submit either 
electronic or written comments and ask for a redetermination by August 
16, 2016. 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 by December 14, 2016.

SUPPLEMENTARY INFORMATION:

I. 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

[[Page 39649]]

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 Nos. 6,515,009 and 
7,820,193) from Boston Scientific Scimed, Inc., and the USPTO requested 
FDA's assistance in determining this patent's eligibility for patent 
term restoration. In a letter dated May 11, 2015, 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.

II. 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. The applicant claims that 
the investigational device exemption (IDE) required under section 
520(g) of the FD&C Act for human tests to begin became effective on 
July 28, 2004. However, FDA records indicate that the IDE was 
determined substantially complete for clinical studies to have begun on 
June 16, 2004, which represents the IDE effective date.
    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. The applicant claims April 1, 2009, as the date the premarket 
approval application (PMA) for ZILVER PTX DRUG ELUTING PERIPHERAL STENT 
(PMA P100022) was initially submitted. However, FDA records indicate 
that PMA P100022 was submitted in full on June 4, 2010.
    3. The date the application was approved: November 14, 2012. The 
applicant claims that the PMA P100022 was approved on November 15, 
2012. However, FDA records indicate 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 applications for patent extension, 
this applicant seeks 1,826 days or 751 days of patent term extension.

III. 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.
