Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for PRADAXA (U.S. Patent No. 6,087,380) from Boehringer Ingelheim Pharma GmbH & Co. KG, 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 25, 2011, FDA advised the Patent and Trademark Office that this human drug product had undergone a regulatory review period and that the approval of PRADAXA 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 PRADAXA is 2,633 days. Of this time, 2,449 days occurred during the testing phase of the regulatory review period, while 184 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 (the FD&C Act) (21 U.S.C. 355(i)) became effective: August 6, 2003. The applicant claims August 7, 2003, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was August 6, 2003, which was 30 days after FDA receipt of the IND. 2. The date the application was initially submitted with respect to the human drug product under section 505(b) of the FD&C Act: April 19, 2010. The applicant claims December 15, 2009, as the date the new drug application (NDA) for PRADAXA (NDA 22–512) was initially submitted. However, FDA records indicate that NDA 22–512, received December 15, 2009, was incomplete. FDA refused to file this application and notified the applicant of this fact by letter dated February 12, 2010. The completed NDA was then submitted on April 19, 2010, which is considered to be the NDA initially submitted date. 3. The date the application was approved: October 19, 2010. FDA has verified the applicant’s claim that NDA 22–512 was approved on October 19, 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. VerDate Mar<15>2010 15:32 May 02, 2012 Jkt 226001 In its application for patent extension, this applicant seeks 1,469 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) either electronic or written comments and ask for a redetermination by July 2, 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 October 30, 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. Interested persons may submit to the Division of Dockets Management (see ADDRESSES) electronic or written comments and written petitions.

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 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 Patents and Trademarks 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 recently approved for marketing the human biologic product KRYSTEXXA (pegloticase). KRYSTEXXA is indicated for treatment of chronic gout in adult patients refractory to conventional therapy.

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 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 Patents and

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 recently approved for marketing the human biologic product 
KRYSTEXXA (pegloticase). KRYSTEXXA is indicated for treatment of 
chronic gout in adult patients refractory to conventional therapy. 
Subsequent to this approval, the Patent and Trademark Office received a 
patent term restoration application for KRYSTEXXA (U.S. Patent No.

6,783,965) from Mountain View Pharmaceuticals, Inc., and Duke 
University, 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 human biological product had undergone a 
regulatory review period and that the approval of KRYSTEXXA 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 
KRYSTEXXA is 3,193 days. Of this time, 2,509 days occurred during the 
testing phase of the regulatory review period, while 684 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: December 
19, 2001. FDA has verified the applicant's claim that the date the 
investigational new drug application became effective was on December 
19, 2001.
    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): October 31, 2008. FDA has verified the 
applicant's claim that the biologics license application (BLA) for 
KRYSTEXXA (BLA 125293) was initially submitted on October 31, 2008.
    3. The date the application was approved: September 14, 2010. FDA 
has verified the applicant's claim that BLA 125293 was approved on 
September 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 1,445 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) either electronic or written comments and ask for a 
redetermination by July 2, 2012. Furthermore, any interested person may

extension acted with due diligence during the regulatory review period 
by October 30, 2012. To meet its burden, the petition must contain
