    Determination of Regulatory Review Period for Purposes of Patent

    ACTION: Notice.

    SUMMARY: The Food and Drug Administration (FDA) has determined the 
    regulatory review period for Ray Threaded Fusion CageTM and 
    is publishing this notice of that determination as required by law. FDA 
    has made the determination because of the submission of an application 
    to the Commissioner of Patents and Trademarks, Department of Commerce, 
    for the extension of a patent which claims that medical device.
    
    ADDRESSES: Written comments and petitions should be directed to the 
    Dockets Management Branch (HFA-305), Food and Drug Administration, 5630 
    Fishers Lane, rm. 1061, Rockville, MD 20852.
    
    FOR FURTHER INFORMATION CONTACT: Brian J. Malkin, Office of Health 
    Affairs (HFY-20), Food and Drug Administration, 5600 Fishers Lane, 
    Rockville, MD 20857, 301-827-6620.
    
    SUPPLEMENTARY INFORMATION: 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 Commissioner of Patents and Trademarks 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 recently approved for marketing the medical device Ray Threaded 
    Fusion CageTM. Ray Threaded Fusion CageTM is 
    indicated for use with autogenous bone graft in patients with 
    degenerative disk disease (DDD) at one or two levels from L2 to S1. 
    These DDD patients may also have up to Grade 1 spondylolisthesis at the 
    involved level(s). Subsequent to this approval, the Patent and 
    Trademark Office received a patent term restoration application for Ray 
    Threaded Fusion CageTM (U.S. Patent No. 4,961,740) from 
    United States Surgical Corp., and the Patent and Trademark Office 
    requested FDA's assistance in determining this patent's eligibility for 
    patent term restoration. In a letter dated April 11, 1997, FDA advised 
    the Patent and Trademark Office that this medical device had undergone 
    a regulatory review period and that the approval of Ray Threaded Fusion 
    CageTM represented the first permitted commercial marketing 
    or use of the product. Shortly thereafter, the Patent and Trademark 
    Office requested that FDA determine the product's regulatory review 
    period.
        FDA has determined that the applicable regulatory review period for 
    Ray Threaded Fusion CageTM is 1,861 days. Of this time, 
    1,357 days occurred during the testing phase of the regulatory review 
    period, while 504 days occurred during the approval phase. These 
    periods of time were derived from the following dates:
        1. The date a clinical investigation involving this device was 
    begun: September 27, 1991. The applicant claims that the 
    investigational device exemption (IDE) required under section 520(g) of 
    the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360j(g)) 
    for human tests to begin became effective on November 15, 1991. 
    However, FDA records indicate that the IDE was determined substantially 
    complete for clinical studies to have begun on September 27, 1991, 
    which represents the IDE effective date.
        2. The date the application was initially submitted with respect to 
    the device under section 515 of the act (21 U.S.C. 360e): June 14, 
    1995. FDA has verified the applicant's claim that the premarket 
    approval application (PMA) for Ray Threaded Fusion CageTM 
    (PMA P950019) was initially submitted June 14, 1995.
        3. The date the application was approved: October 29, 1996. FDA has 
    verified the applicant's claim that PMA P950019 was approved on October 
    29, 1996.
        This determination of the regulatory review period establishes the 
    maximum potential length of a patent extension. However, the U.S. 
    Patent and Trademark Office applies several statutory limitations in 
    its calculations of the actual period for patent extension. In its 
    application for patent extension, this applicant seeks 742 days of 
    patent term extension.
        Anyone with knowledge that any of the dates as published is 
    incorrect may, on or before December 14, 1998, submit to the Dockets 
    Management Branch (address above) written comments and ask for a 
    redetermination. Furthermore, any interested person may petition FDA, 
    on or before April 12, 1999, 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 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.
        Comments and petitions should be submitted to the Dockets 
    Management Branch (address above) in three copies (except that 
    individuals may submit single copies) and identified with the

    docket number found in brackets in the heading of this document. 
    Comments and petitions may be seen in the Dockets Management Branch 
    between 9 a.m. and 4 p.m., Monday through Friday.
    
        Dated: September 28, 1998.
    Thomas J. McGinnis,
    Deputy Associate Commissioner for Health Affairs.
