MPEP 200 – Types and Status of Application; Benefit and Priority (5)
What is the significance of copendency in continuation applications?
Copendency is a crucial requirement for continuation applications. It refers to the condition where the continuation application is filed before the prior application is patented, abandoned, or terminated. The MPEP 201.07 states:
‘To be entitled to the benefit of the filing date of an earlier-filed application, the later-filed application must be an application for a patent for an invention which is also disclosed in the prior application (the parent or original nonprovisional application or provisional application); the disclosure of the invention in the prior application and in the later-filed application must be sufficient to comply with the requirements of 35 U.S.C. 112(a) except for the best mode requirement; and the later-filed application must be copending with the prior application.’
The significance of copendency includes:
- Maintaining Priority: It ensures the continuation application can claim the benefit of the earlier filing date.
- Unbroken Chain: It maintains an unbroken chain of applications, which is essential for establishing a continuous line of priority.
- Preventing Loss of Rights: Filing a continuation before the parent application is concluded prevents the loss of patent rights that could occur if new claims are needed after the parent application is no longer pending.
Failure to maintain copendency can result in the loss of the earlier priority date, potentially affecting the patentability of the invention if intervening prior art exists.

Yes, a continuation application can claim priority to multiple parent applications under certain conditions. According to MPEP 201.07:
‘A continuation application may be filed as a continuation of an earlier application of the same applicant… The continuation application may be filed before the patenting or abandonment of or termination of proceedings on the prior application.’
This means that:
- The continuation must have at least one common inventor with the parent application(s).
- The continuation must be filed while at least one of the parent applications is still pending.
- The continuation cannot introduce new matter beyond what was disclosed in the parent application(s).
When claiming priority to multiple parents, the continuation essentially combines the disclosures of the parent applications, as long as they form a continuous chain of copending applications.

An inventor’s certificate is a form of intellectual property protection offered in some countries. It can form the basis for priority rights under certain conditions, as stated in 35 U.S.C. 119(d):
Applications for inventors’ certificates filed in a foreign country in which applicants have a right to apply, at their discretion, either for a patent or for an inventor’s certificate shall be treated in this country in the same manner and have the same effect for purpose of the right of priority under this section as applications for patents…
This means that if an applicant had the option to file for either a patent or an inventor’s certificate in the foreign country, they can claim priority based on the inventor’s certificate application in the United States.

The filing date of a continuation application can significantly affect its patent term. While the continuation application gets the benefit of the earlier filing date for prior art purposes, its actual filing date is used to calculate the patent term. According to MPEP 201.07:
The filing date of a continuation application is the filing date of the parent application.
However, this refers to the priority date for prior art purposes. The actual patent term is calculated from the filing date of the continuation application itself. Here’s how it works:
- The patent term is generally 20 years from the filing date of the earliest non-provisional application to which priority is claimed.
- For a continuation application, this means 20 years from the filing date of the parent non-provisional application.
- Each continuation in a chain reduces the effective patent term.
It’s crucial to consider this when deciding whether to file a continuation or a new application, as it can impact the overall protection period for your invention.

The USPTO recognizes that some countries have restrictions on who can apply for patents versus inventor’s certificates. As stated in MPEP 213.05:
It is recognized that certain countries that grant inventors’ certificates also provide by law that their own nationals who are employed in state enterprises may only receive inventors’ certificates and not patents on inventions made in connection with their employment. This will not impair their right to be granted priority in the United States based on the filing of the inventor’s certificate.
This means that even if an applicant was restricted to filing for an inventor’s certificate in their home country due to employment or nationality, they can still claim priority in the US based on that filing. The key factor is whether the option to file for either a patent or an inventor’s certificate generally existed in the country for the particular subject matter, not whether the specific applicant had that choice.
