Determination of Regulatory Review Period for Purposes of Patent 
Extension; SIMPLIFY CERVICAL ARTIFICIAL DISC

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 SIMPLIFY CERVICAL 
ARTIFICIAL DISC and is publishing this notice of that determination as

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 
SUPPLEMENTARY INFORMATION) are incorrect must submit either electronic 
or written comments and ask for a redetermination by April 15, 2024. 
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 August 12, 2024. 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 or biological 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 SIMPLIFY CERVICAL 
ARTIFICIAL DISC. SIMPLIFY CERVICAL ARTIFICIAL DISC is indicated for use 
in skeletally mature patients for reconstruction of the disc at one 
level from C3-C7 following single-level discectomy for intractable 
radiculopathy (arm pain and/or a neurological deficit) with or without 
neck pain, or myelopathy due to a single-level abnormality localized to 
the level of the disc space and manifested by at least one of the 
following conditions confirmed by radiographic imaging (e.g., X-rays, 
computed tomography, magnetic resonance imaging): herniated nucleus 
pulposus, spondylosis (defined by the presence of progressive symptoms 
(e.g., numbness or tingling)) prior to implantation. Subsequent to this 
approval, the USPTO received patent term restoration applications for 
SIMPLIFY CERVICAL ARTIFICIAL DISC (U.S. Patent Nos. 7,753,956 and 
9,107,762) from Simplify Medical Pty Ltd., and the USPTO requested 
FDA's assistance in determining the patents' eligibility for patent 
term restoration. In a letter dated January 18, 2023, FDA advised the 
USPTO that this medical device had undergone a regulatory review period 
and that the approval of SIMPLIFY CERVICAL ARTIFICIAL DISC 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 
SIMPLIFY CERVICAL ARTIFICIAL DISC is 2,020 days. Of this time, 1,842 
days occurred during the testing phase of the regulatory review period, 
while 178 days occurred during the approval phase. These periods of 
time were derived from the following dates:
    1. The date an exemption for this device, under section 520(g) of 
the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 
360j(g)), became effective: March 11, 2015. FDA has verified the 
applicant's claim that the date the investigational device exemption 
for human tests to begin, as required under section 520(g) of the FD&C 
Act, became effective March 11, 2015.
    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): March 
25, 2020. FDA has verified the applicant's claim that the premarket 
approval application (PMA) for SIMPLIFY CERVICAL ARTIFICIAL DISC (PMA 
P200022) was initially submitted March 25, 2020.
    3. The date the application was approved: September 18, 2020. FDA 
has verified the applicant's claim that PMA P200022 was approved on 
September 18, 2020.
    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 1,098 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.
