Determination of Regulatory Review Period for Purposes of Patent 
Extension; Progel Pleural Air Leak Sealant

AGENCY: Food and Drug Administration, HHS.

ACTION: Notice.

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

SUMMARY: The Food and Drug Administration (FDA) has determined the 
regulatory review period for Progel Pleural Air Leak Sealant 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.

ADDRESSES: Submit electronic comments to http://www.regulations.gov. 
Submit written petitions along with three copies and written comments 
to the Division of Dockets Management (HFA-305), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville, MD 20852.

FOR FURTHER INFORMATION CONTACT: Beverly Friedman, Office of Regulatory 
Policy, Food and Drug Administration, 10903 New Hampshire Ave., Bldg. 
51, Rm. 6284, Silver Spring, MD 20993-0002, 301-796-3602.

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, Progel 
Pleural Air Leak Sealant. Progel Pleural Air Leak Sealant is indicated 
for application to visceral pleura during an open thoracotomy after 
standard visceral pleural closure with, for example, sutures or 
staples, of visible air leaks (>=2 mm) incurred during open resection 
of lung parenchyma. Subsequent to this approval, the Patent and 
Trademark Office received a patent term restoration application for 
Progel Pleural Air Leak Sealant (U.S. Patent No. RE38158) from Neomend, 
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 June 8, 2011, FDA advised the Patent and Trademark Office 
that this medical device had undergone a regulatory review period and 
that the approval of Progel Pleural Air Leak Sealant represented the 
first permitted commercial marketing or use of the product. Thereafter, 
the Patent and Trademark Office requested that the FDA determine the 
product's regulatory review period.
    FDA has determined that the applicable regulatory review period for 
Progel Pleural Air Leak Sealant is 3,854 days. Of this time, 787 days 
occurred during the testing phase of the regulatory review period, 
while 3067 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 29, 1999. 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 June 29, 1999.
    2. The date an application was initially submitted with respect to 
the device under section 515 of the Federal Food, Drug, and Cosmetic 
Act (21 U.S.C. 360e): August 23, 2001. FDA has verified the applicant's 
claim that the premarket approval application (PMA) for Progel Pleural 
Air Leak Sealant (PMA P010047) was initially submitted August 23, 2001.
    3. The date the application was approved: January 14, 2010. FDA has 
verified the applicant's claim that PMA P010047 was approved on January 
14, 2010.
    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 5 years 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) either electronic or written comments and ask for a 
redetermination by August 10, 2012. 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 10, 2012. 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.
