Extension; ARTEFILL

ACTION:  Notice.

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

SUMMARY:  The Food and Drug Administration (FDA) has determined the 
regulatory review period for ARTEFILL 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 Director of Patents 
and Trademarks, Department of Commerce, for the extension of a patent 
which claims that medical device.

SUPPLEMENTARY INFORMATION: The Drug Price Competition and Patent Term 
Restoration Act of 1984 (Public Law 98-417) and the Generic Animal Drug 
and Patent Term Restoration Act (Public Law 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 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, ARTEFILL. 
ARTEFILL is indicated for correction of nasolabial folds. Subsequent to 
this approval, the Patent and Trademark Office received a patent term 
restoration application for ARTEFILL (U.S. Patent No. 5,344,452) from 
Artes Medical USA, Inc., and the Patent and Trademark Office requested 
FDA's assistance in determining this patent's eligibility for patent 
term restoration. In a letter dated May 16, 2007, FDA advised the 
Patent and Trademark Office that this medical device had undergone a 
regulatory review period and that the approval of ARTEFILL represented 
the first permitted commercial marketing or use of the product. 
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 
ARTEFILL is 3,530 days. Of this time, 1,859 days occurred during the 
testing phase of the regulatory review period, while 1671 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 act) (21 U.S.C. 360j(g)) involving this 
device became effective: February 28, 1997. FDA has verified the 
applicant's claim that the date the investigational device exemption 
(IDE) required under section 520(g) of the act for human tests to begin 
became effective February 28, 1997.
    2. The date an application was initially submitted with respect to 
the device under section 515 of the act (21 U.S.C. 360e): April 1, 
2002. FDA has verified the applicant's claim that the premarket 
approval application (PMA) for ARTEFILL (PMA P020012) was initially 
submitted April 1, 2002.
    3. The date the application was approved: October 27, 2006. FDA has 
verified the applicant's claim that PMA P020012 was approved on October 
27, 2006.
    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 1,827 days of 
patent term extension.
    Anyone with knowledge that any of the dates as published are 
incorrect may submit to the Division of Dockets Management (see 
ADDRESSES) written or electronic comments and ask for a redetermination 
by June 30, 2008. 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 October 28, 
2008. 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 Division of 
Dockets Management. Three copies of any mailed information are to be 
submitted, except that individuals may submit one copy. Comments are to 
be identified with the docket number found in brackets in the heading 
of this document. Comments and petitions may be seen in the Division of 
Dockets Management between 9 a.m. and 4 p.m., Monday through Friday.
    Please note that on January 15, 2008, the FDA Division of Dockets 
Management Web site transitioned to the Federal Dockets Management 
System (FDMS). FDMS is a Government-wide, electronic docket management 
system. Electronic comments or submissions will be accepted by FDA only 
through FDMS at http://www.regulations.gov.
