Determination of Regulatory Review Period for Purposes of Patent 
Extension; MICRA TRANSCATHETER PACING SYSTEM

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Food and Drug Administration (FDA or the Agency) has 
determined the regulatory review period for MICRA TRANSCATHETER PACING 
SYSTEM and is publishing this notice of that determination as required 
by law. FDA has made the determination because of the submission of

(USPTO), Department of Commerce, for the extension of a patent which 
claims 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 March 
12, 2018. 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 July 10, 2018. See 
``Petitions'' in the SUPPLEMENTARY INFORMATION section for more 
information.

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

[[Page 1371]]

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 MICRA 
TRANSCATHETER PACING SYSTEM. MICRA TRANSCATHETER PACING SYSTEM is 
indicated for use in patients who have experienced one or more of the 
following conditions: (1) Symptomatic paroxysmal or permanent high-
grade atrioventricular (AV) block in the presence of atrial 
fibrillation (AF); (2) symptomatic paroxysmal or permanent high-grade 
AV block in the absence of AF, as an alternative to dual chamber 
pacing, when atrial lead placement is considered difficult, high risk, 
or not deemed necessary for effective therapy; (3) symptomatic 
bradycardia-tachycardia syndrome or sinus node dysfunction (sinus 
bradycardia or sinus pauses), as an alternative to atrial or dual 
chamber pacing when atrial lead placement is considered difficult, high 
risk, or not deemed necessary for effective therapy. Subsequent to this 
approval, the USPTO received patent term restoration applications for 
MICRA TRANSCATHETER PACING SYSTEM (U.S. Patent Nos. 7,824,805 and 
8,129,622) from Medtronic, Inc., and the USPTO requested FDA's 
assistance in determining the patents' eligibility for patent term 
restoration. In a letter dated March 13, 2017, FDA advised the USPTO 
that this medical device had undergone a regulatory review period and 
that the approval of MICRA TRANSCATHETER PACING SYSTEM 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 
MICRA TRANSCATHETER PACING SYSTEM is 788 days. Of this time, 585 days 
occurred during the testing phase of the regulatory review period, 
while 203 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 (FD&C Act) (21 U.S.C. 360j(g)) involving this 
device became effective: February 10, 2014. 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 
April 3, 2014. However, FDA records indicate that the IDE was 
determined substantially complete for clinical studies to have begun on 
February 10, 2014, 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): 
September 17, 2015. FDA has verified the applicant's claim that the 
premarket approval application (PMA) for MICRA TRANSCATHETER PACING 
SYSTEM (PMA P150033) was initially submitted September 17, 2015.
    3. The date the application was approved: April 6, 2016. FDA has 
verified the applicant's claim that PMA P150033 was approved on April 
6, 2016.
    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 457 days and 494 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, under 
21 CFR 60.24, ask for a redetermination (see DATES). Furthermore, as 
specified in Sec.  60.30 (21 CFR 60.30), 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 comply with all the requirements 
of Sec.  60.30, including but not limited to: Must be timely (see 
DATES), must be filed in accordance with Sec.  10.20, must contain 
sufficient facts to merit an FDA investigation, and must certify that a 
true and complete copy of the petition has been served upon the patent 
applicant. (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 https://www.regulations.gov at 
Docket No. FDA-2013-S-0610. Submit written petitions (two copies are 
required) to the Dockets Management Staff (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

    Dated: January 8, 2018.
