MPEP 200 - Types and Status of Application; Benefit and Priority (8)
An inventor might consider filing a continuation application in several scenarios. The MPEP 201.07 provides guidance on timing:
At any time before the patenting, abandonment, or termination of proceedings on an earlier application, an applicant may have recourse to filing a continuation application under 37 CFR 1.53(b) in order to introduce into the application a new set of claims and to establish a right to further examination by the Office.
Common reasons for filing a continuation include:
- To pursue broader or different claims based on the same disclosure
- To address issues raised in the prosecution of the parent application
- To keep the application pending while exploring commercial opportunities
- To submit new evidence or arguments in support of patentability
It’s important to note that the continuation must be filed before the parent application is patented, abandoned, or otherwise terminated.

Filing a continuation application serves several important purposes in patent prosecution. The MPEP indicates:
At any time before the patenting, abandonment, or termination of proceedings on an earlier application, an applicant may have recourse to filing a continuation application under 37 CFR 1.53(b) in order to introduce into the application a new set of claims and to establish a right to further examination by the Office.
Key reasons for filing a continuation include:
- Pursuing broader or different claim scope based on the same disclosure
- Addressing remaining rejections or objections from the parent application
- Submitting new evidence or arguments to overcome prior art rejections
- Maintaining pendency for ongoing improvements or to counter competitor activities
- Separating distinct inventions identified during examination of the parent
Continuations allow applicants to refine their patent strategy while maintaining the priority date of the original filing, which can be crucial in fast-moving technological fields.

Filing a divisional application allows an applicant to pursue protection for distinct inventions disclosed in a parent application. Key benefits include:
- Ability to claim different aspects or embodiments of the invention
- Potential for broader patent coverage
- Preservation of priority date for the disclosed subject matter
- Opportunity to pursue claims that may have been restricted in the parent application
The MPEP indicates: A divisional application is often filed as a result of a restriction requirement made by the examiner.
This suggests that divisional applications provide a way to pursue protection for inventions that were not elected in the parent application due to a restriction requirement.

Filing a continuation application offers several benefits to patent applicants:
- Pursuing additional claims: As stated in MPEP 201.07, “The disclosure presented in the continuation must be the same as that of the original application; i.e., the continuation should not include anything which would constitute new matter if inserted in the original application.” This allows applicants to pursue different or broader claims based on the same disclosure.
- Extending prosecution: A continuation application provides more time to negotiate with the USPTO, potentially leading to stronger patent protection.
- Maintaining pendency: It keeps the application pending, which can be strategically important in fast-evolving technologies or competitive markets.
- Addressing new prior art: If new prior art emerges during the prosecution of the parent application, a continuation allows for claim adjustments to overcome this art.
- Commercial considerations: As products evolve or market conditions change, continuation applications allow for tailoring claims to cover new aspects of the invention or competitor products.
By utilizing continuation applications strategically, inventors and businesses can build a stronger patent portfolio and maintain flexibility in their intellectual property protection strategy.

Filing a continuation-in-part (CIP) application has several benefits and potential drawbacks:
Benefits:
- Allows addition of new subject matter to an existing invention
- Maintains the priority date of the original application for common subject matter
- Provides an opportunity to strengthen the patent application with new data or improvements
- Allows for changes in inventorship to reflect new contributions
Drawbacks:
- New subject matter only gets the filing date of the CIP, potentially exposing it to more prior art
- Can complicate the patent term calculation
- May result in multiple patents with overlapping subject matter, requiring terminal disclaimers
- Increases overall costs due to additional filing and prosecution fees
The MPEP notes: “The mere filing of a continuation-in-part application does not itself create a presumption that the applicant acquiesces in any rejections which may be outstanding in the copending national nonprovisional application or applications upon which the continuation-in-part application relies for benefit.”
Inventors and patent attorneys should carefully consider these factors when deciding whether to file a CIP or a new application.

Filing a provisional patent application offers several advantages, as outlined in the MPEP:
- Establishing Priority: It allows applicants to
quickly and inexpensively file provisional applications
and establish a priority date for their invention. - Paris Convention Priority: It
starts the Paris Convention priority year
, allowing foreign filings within 12 months while maintaining the U.S. filing date. - Simplified Filing: As stated in the MPEP,
No claim is required in a provisional application
andNo oath or declaration is required in a provisional application.
- Patent Term: The MPEP notes,
The domestic priority period will not count in the measurement of the 20-year patent term.
This putsdomestic applicants… on equal footing with foreign applicants with respect to the patent term.
- Time for Development: It provides a 12-month period to further develop the invention before filing a nonprovisional application.
These advantages make provisional applications a useful tool for inventors to secure an early filing date while allowing time for further development and market assessment.

Claiming benefit to a prior application can affect the patent term in several ways:
- For applications subject to the 20-year term provision:
- The term begins from the earliest U.S. filing date to which benefit is claimed under 35 U.S.C. 120, 121, or 365(c)
- Claiming benefit to earlier applications may reduce the effective patent term
- For provisional applications:
- Claiming benefit under 35 U.S.C. 119(e) does not affect the patent term
- However, claiming benefit to a provisional under 35 U.S.C. 120 (not recommended) could reduce the term
MPEP 211.02 cautions: “Although 35 U.S.C. 120 does not preclude a benefit claim to a provisional application, it is not recommended that applicants claim the benefit to a provisional application under 35 U.S.C. 120 since such a claim could have the effect of reducing the patent term, as the term of a patent issuing from such an application may be measured from the filing date of the provisional application pursuant to 35 U.S.C. 154(a)(2).”
It’s important to carefully consider the implications of benefit claims on patent term when developing a patent strategy, especially for patent families with multiple related applications.
To learn more:
Can I file multiple provisional applications for the same invention?
Yes, you can file multiple provisional applications for the same invention. This practice is sometimes used to establish earlier priority dates for different aspects of an invention as they are developed. The MPEP 201.04 does not explicitly prohibit this practice.
However, it’s important to note:
- Each provisional application must meet the requirements for disclosure and enablement
- The 12-month deadline for filing a nonprovisional application starts from the earliest provisional application you wish to claim benefit from
- When filing the nonprovisional application, you can claim the benefit of multiple provisional applications
For example, the MPEP states:
“A nonprovisional application may claim the benefit of one or more prior provisional applications under 35 U.S.C. 119(e).”
While this strategy can be beneficial, it’s advisable to consult with a patent attorney to ensure proper execution and to avoid potential pitfalls.

MPEP 200 - Types and Status of Application; Benefit and Priority Claims (1)
Filing a continuation-in-part (CIP) application can present several risks and potential drawbacks:
1. Different Effective Filing Dates: New matter in the CIP only gets the benefit of the CIP filing date, potentially exposing those claims to more prior art.
2. Reduced Patent Term: The patent term is measured from the filing date of the earliest application to which the CIP claims priority, potentially reducing the overall protection period for new matter.
3. Double Patenting Issues: Claims in the CIP may be subject to obviousness-type double patenting rejections based on the claims of the parent application.
4. Complexity in Litigation: The varying effective filing dates can complicate patent litigation, particularly when determining relevant prior art.
5. Difficulty in Claiming Priority: International applications may have difficulty claiming priority to a CIP due to the new matter.
While not explicitly stated in the provided MPEP section, these are important considerations derived from patent law and practice. The MPEP does note: “The mere filing of a continuation-in-part application does not itself create a presumption that the applicant acquiesces in any rejections which may be outstanding in the copending national nonprovisional application or applications upon which the continuation-in-part application relies for benefit.”
Applicants should carefully consider these factors when deciding whether to file a CIP or a new application.

Can I file multiple provisional applications for the same invention?
Yes, you can file multiple provisional applications for the same invention. This practice is sometimes used to establish earlier priority dates for different aspects of an invention as they are developed. The MPEP 201.04 does not explicitly prohibit this practice.
However, it’s important to note:
- Each provisional application must meet the requirements for disclosure and enablement
- The 12-month deadline for filing a nonprovisional application starts from the earliest provisional application you wish to claim benefit from
- When filing the nonprovisional application, you can claim the benefit of multiple provisional applications
For example, the MPEP states:
“A nonprovisional application may claim the benefit of one or more prior provisional applications under 35 U.S.C. 119(e).”
While this strategy can be beneficial, it’s advisable to consult with a patent attorney to ensure proper execution and to avoid potential pitfalls.
