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 or biological 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 USPTO 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 has approved for marketing the 

medical device OCS LIVER. OCS LIVER 

is indicated for preservation and 

monitoring of hemodynamics and 

metabolic function which allows for exvivo assessment of liver allografts from 

donors after brain death or liver 

allografts from donors after circulatory 

death <=55 years old and with <=30 

minutes of warm ischemic time, 

macrosteatosis <=15%, in a nearphysiologic, normothermic and 

functioning state intended for a 

potential transplant recipient. 

Subsequent to this approval, the USPTO 

received a patent term restoration 

application for OSC LIVER (U.S. Patent 

No. 10,076,112) from TransMedics, Inc., 

and the USPO requested FDA’s 

assistance in determining this patent’s 

eligibility for patent term restoration. In 

a letter dated September 28, 2022, FDA 

advised the USPTO that this medical 

device had undergone a regulatory 

review period and that the approval of 

OSC LIVER 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 

OCS LIVER is 2,275 days. Of this time, 

1,819 days occurred during the testing 

phase of the regulatory review period, 

while 456 days occurred during the 

approval phase. These periods of time 

were derived from the following dates: 

1. The date an exemption for this 

device, under section 520(g) of the 

Federal Food, Drug, and Cosmetic Act 

(FD&C Act) (21 U.S.C. 360j(g)), became 

effective: July 9, 2015. FDA has verified 

the applicant’s claim that the date the 

investigational device exemption for 

human tests to begin, as required under 

section 520(g) of the FD&C Act, became 

effective July 9, 2015. 

2. The date an application was 

initially submitted with respect to the 

device under section 515 of the FD&C 

Act (21 U.S.C. 360e): June 30, 2020. FDA 

has verified the applicant’s claim that 

the premarket approval application 

(PMA) for OCS LIVER (PMA P20031) 

was initially submitted June 30, 2020. 

3. The date the application was 

approved: September 28, 2021. FDA has 

verified the applicant’s claim that PMA 

P20031 was approved on September 28, 

2021. 

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 72 days 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, under 21 CFR 60.24, ask 

for a redetermination (see DATES). 

Furthermore, as specified in § 60.30 (21 

CFR 60.30), 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 

comply with all the requirements of 

§ 60.30, including but not limited to: 

must be timely (see DATES), must be 

filed in accordance with § 10.20, must 

contain sufficient facts to merit an FDA 

investigation, and must certify that a 

true and complete copy of the petition 

has been served upon the patent 

applicant. (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.

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 or biological 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 product 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 SKYTROFA 

(lonapegsomatropin-tcgd). SKYTROFA 

is indicated for the treatment of 

pediatric patients 1 year and older who 

weigh at least 11.5 kilograms and have 

growth failure due to inadequate 

secretion of endogenous growth 

hormone. Subsequent to this approval, 

the USPTO received a patent term 

restoration application for SKYTROFA 

(U.S. Patent Nos. 9,272,048; 9,511,122; 

and 10,682,395) from Ascendis Pharma 

Endocrinology Division A/S, and the 

USPTO requested FDA’s assistance in 

determining this patent’s eligibility for 

patent term restoration. In a letter dated 

September 28, 2022, FDA advised the 

USPTO that this human biological 

product had undergone a regulatory 

review period and that the approval of 

SKYTROFA 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 

SKYTROFA is 2,133 days. Of this time, 

1,706 days occurred during the testing 


ddrumheller on DSK120RN23PROD with NOTICES1
11306 Federal Register / Vol. 89, No. 31 / Wednesday, February 14, 2024 / Notices 

phase of the regulatory review period, 

while 427 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 25, 2015. FDA 

has verified the applicant’s claim that 

the date the investigational new drug 

application became effective was on 

October 25, 2015. 

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): June 25, 2020. FDA has 

verified the applicant’s claim that the 

biologics license application (BLA) for 

SKYTROFA (BLA 761177) was initially 

submitted on June 25, 2020. 

3. The date the application was 

approved: August 25, 2021. FDA has 

verified the applicant’s claim that BLA 

761177 was approved on August 25, 

2021. 

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 applications for patent extension, 

this applicant seeks 431 days, 1,075 

days or 1,215 days of patent term 

extension.

Anyone with knowledge that any of 

the dates as published are incorrect may
