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 human biological products, the 
testing phase begins when the exemption to permit the clinical 
investigations of the biological becomes effective and runs until the 
approval phase begins. The approval phase starts with the initial 
submission of an application to market the human biological product and 
continues until FDA grants permission to market the biological product. 
Although only a portion of a regulatory review period may count toward 
the actual amount of extension that the Director of USPTO may award 
(for example, 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 human 
biological product will include all of the testing phase and approval 
phase as specified in 35 U.S.C. 156(g)(1)(B).
    FDA has approved for marketing the human biologic product ANAVIP 
(crotalidae Immune F(ab')2 (equine)). ANAVIP is indicated for 
management of adult and pediatric patients with North American 
rattlesnake envenomation. Subsequent to this approval, the USPTO 
received a patent term restoration application for ANAVIP (U.S. Patent 
No. 6,709,655) from Instituto Bioclon, SA de CV, and the USPTO 
requested FDA's assistance in determining this patent's eligibility for 
patent term restoration. In a letter dated March 10, 2016, FDA advised 
the USPTO that this human biological product had undergone a regulatory 
review period and that the approval of ANAVIP 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 
ANAVIP is 4,223 days. Of this time, 3,443 days occurred during the 
testing

[[Page 83847]]

phase of the regulatory review period, while 780 days occurred during 
the approval phase. These periods of time were derived from the 
following dates:
    1. The date an exemption under section 505(i) of the Federal Food, 
Drug, and Cosmetic Act (21 U.S.C. 355(i)) became effective: October 15, 
2003. FDA has verified the applicant's claim that the date the 
investigational new drug application became effective was on October 
15, 2003.
    2. The date the application was initially submitted with respect to 
the human biological product under section 351 of the Public Health 
Service Act (42 U.S.C. 262): March 18, 2013. FDA has verified the 
applicant's claim that the biologics license application (BLA) for 
ANAVIP (BLA 125488/0) was initially submitted on March 18, 2013.
    3. The date the application was approved: May 6, 2015. FDA has 
verified the applicant's claim that BLA 125488/0 was approved on May 6, 
2015.
    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 application for patent extension, 
this 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 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.
