Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
Adjustments (1)
A terminal disclaimer can limit the effect of patent term adjustment (PTA). According to MPEP 2731:
“37 CFR 1.703(g) indicates that no patent, the term of which has been disclaimed beyond a specified date, shall be adjusted under 37 CFR 1.702 and 1.703 beyond the expiration date specified in the disclaimer (35 U.S.C. 154(b)(2)(B)).“
This means that if a patent applicant has filed a terminal disclaimer, agreeing that the patent will expire on a certain date (typically to avoid a double patenting rejection), the PTA cannot extend the patent term beyond that date. The terminal disclaimer effectively sets an upper limit on the total term of the patent, regardless of any delays that might otherwise qualify for PTA.
It’s important for applicants to consider the potential impact on PTA when deciding whether to file a terminal disclaimer, especially in cases where significant USPTO delays have occurred during prosecution. In some cases, it may be advantageous to address double patenting issues through other means if preserving PTA is a priority.

MPEP 200 – Types and Status of Application; Benefit and Priority Claims (1)
Claiming priority to a foreign application generally does not affect the term of a U.S. patent. The patent term is typically calculated from the actual U.S. filing date, not the foreign priority date.
For utility and plant patents:
– The term is 20 years from the earliest U.S. filing date of the application or any U.S. application to which it claims benefit under 35 U.S.C. 120, 121, or 365(c).
– The foreign priority date is not used in this calculation.
For design patents:
– The term is 15 years from the date of grant.
– The filing or priority dates do not affect the term.
It’s important to note that while the foreign priority date doesn’t affect the patent term, it can affect the effective filing date for prior art purposes, which can be crucial for determining patentability.
Patent Term Adjustment (PTA) may be available to extend the term of a utility or plant patent due to delays in prosecution, but this is calculated based on the actual U.S. filing date, not the foreign priority date.
MPEP 213-Right of Priority of Foreign Application (1)
Claiming priority to a foreign application generally does not affect the term of a U.S. patent. The patent term is typically calculated from the actual U.S. filing date, not the foreign priority date.
For utility and plant patents:
– The term is 20 years from the earliest U.S. filing date of the application or any U.S. application to which it claims benefit under 35 U.S.C. 120, 121, or 365(c).
– The foreign priority date is not used in this calculation.

– The filing or priority dates do not affect the term.

MPEP 2700 – Patent Terms (1)
A terminal disclaimer can limit the effect of patent term adjustment (PTA). According to MPEP 2731:
“37 CFR 1.703(g) indicates that no patent, the term of which has been disclaimed beyond a specified date, shall be adjusted under 37 CFR 1.702 and 1.703 beyond the expiration date specified in the disclaimer (35 U.S.C. 154(b)(2)(B)).“
This means that if a patent applicant has filed a terminal disclaimer, agreeing that the patent will expire on a certain date (typically to avoid a double patenting rejection), the PTA cannot extend the patent term beyond that date. The terminal disclaimer effectively sets an upper limit on the total term of the patent, regardless of any delays that might otherwise qualify for PTA.
It’s important for applicants to consider the potential impact on PTA when deciding whether to file a terminal disclaimer, especially in cases where significant USPTO delays have occurred during prosecution. In some cases, it may be advantageous to address double patenting issues through other means if preserving PTA is a priority.
