Determination of Regulatory Review Period for Purposes of Patent 
Extension; NEUROPACE RNS SYSTEM

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for NEUROPACE RNS SYSTEM and is publishing 
this notice of that determination as required by law. FDA has made the 
determination because of the submission of applications to the Director 
of the U.S. Patent and Trademark Office (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 August 
14, 2017. 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 11, 2017. 
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 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 NEUROPACE RNS 
SYSTEM. NEUROPACE RNS SYSTEM is indicated as an adjunctive therapy in 
reducing the frequency of seizures in individuals 18 years of age or 
older with partial onset seizures who have undergone diagnostic testing 
that localized no more than 2 epileptogenic foci, are refractory to two 
or more antiepileptic medications, and currently have frequent and 
disabling seizures (motor partial seizures, complex partial seizures, 
and/or secondarily generalized seizures). Subsequent to this approval, 
the USPTO received patent term restoration applications for NEUROPACE 
RNS SYSTEM (U.S. Patent Nos. 6,016,449; 6,360,122; and 6,810,285) from 
NeuroPace, Inc., and the USPTO requested FDA's assistance in 
determining the patents' eligibility for patent term restoration. In a 
letter dated November 2, 2015, FDA advised the USPTO that this medical 
device had undergone a regulatory review period and that the approval 
of NEUROPACE RNS 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 
NEUROPACE RNS SYSTEM is 3,796 days. Of this time, 2,694 days occurred 
during the testing phase of the regulatory review period, while 1102 
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 26, 2003. 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 26, 2003.
    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): November 
9, 2010. FDA has verified the applicant's claim that the premarket 
approval application (PMA) for NEUROPACE RNS SYSTEM (PMA P100026) was 
initially submitted November 9, 2010.
    3. The date the application was approved: November 14, 2013. FDA 
has verified the applicant's claim that PMA P100026 was approved on 
November 14, 2013.
    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, 
the applicant seeks 5 years 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 
ADDRESSES) 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 https://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.
