Here’s the complete FAQ:
MPEP 200 - Types and Status of Application; Benefit and Priority (20)
The timing for submitting a specific reference to a prior-filed application depends on the type of application:
- For utility or plant applications filed under 35 U.S.C. 111(a):
The specific reference must be submitted during the pendency of the application and within the later of four months from the actual filing date of the application or sixteen months from the filing date of the prior application.
- For national stage applications under 35 U.S.C. 371:
The specific reference must be submitted during the pendency of the application and within the later of four months from the date on which the national stage commenced under 35 U.S.C. 371(b) or (f), four months from the date of the initial submission under 35 U.S.C. 371 to enter the national stage, or sixteen months from the filing date of the prior application.
It’s important to note that This time period is not extendable and a failure to submit the reference required by 35 U.S.C. 119(e) and/or 120, where applicable, within this time period is considered a waiver of any benefit of such prior application(s).

The time limit for filing a U.S. nonprovisional application claiming priority to a foreign application is generally 12 months from the filing date of the foreign application. For design applications, the time limit is 6 months.
As stated in the MPEP, The United States nonprovisional application must be filed not later than twelve months (six months in the case of a design application) after the date on which the foreign application was filed, unless the right of priority has been restored.
(MPEP 213.03)
It’s important to note that this period is subject to certain provisions, such as the extension to the next business day if the deadline falls on a weekend or federal holiday.
To learn more:
A nonprovisional application claiming the benefit of a provisional application under 35 U.S.C. 119(e) must be filed within 12 months after the provisional application’s filing date, unless the benefit has been restored. The MPEP states:
“When a later-filed application is claiming the benefit of a prior-filed provisional application under 35 U.S.C. 119(e), the nonprovisional application must be filed not later than 12 months after the date on which the provisional application was filed, unless the benefit of the provisional application has been restored.”
If the 12-month deadline falls on a Saturday, Sunday, or federal holiday in Washington, D.C., the nonprovisional application can be filed on the next business day.

What is the time limit for filing a divisional application?
There is no specific time limit for filing a divisional application, but there are important considerations that effectively create a practical time frame:
- Parent Application Status: The divisional application must be filed while the parent application is still pending. Once the parent application is either abandoned or issued as a patent, it’s no longer possible to file a divisional from it.
- Priority Claim: To claim the benefit of the parent application’s filing date, the divisional must be filed within the time periods specified in 35 U.S.C. 120, 121, 365(c), or 386(c).
- Patent Term: The 20-year patent term is calculated from the earliest non-provisional U.S. filing date. Filing a divisional later in the parent’s pendency will result in a shorter potential patent term for the divisional.
The MPEP 201.06 states:
A divisional application is often filed as a result of a restriction requirement made by the examiner.
While this doesn’t specify a time limit, it implies that divisional applications are typically filed in response to office actions during the examination process. Applicants should consider filing a divisional promptly after receiving a restriction requirement to ensure they don’t miss any deadlines and to maximize the potential patent term.

For applications filed under 35 U.S.C. 111(a) on or after March 16, 2013, 37 CFR 1.55(f)(1) requires that a certified copy of the foreign application be filed within the later of:
- Four months from the actual filing date of the application, or
- Sixteen months from the filing date of the prior foreign application
This time period does not apply to design applications. There are three exceptions to this requirement, as outlined in 37 CFR 1.55(h), (i), and (j).
To learn more:
What is the significance of the ‘time period set in 37 CFR 1.55’ for filing priority claims?
The time period set in 37 CFR 1.55 is crucial for securing your priority claim in a patent application. MPEP 213.04 states: ‘The time period set in 37 CFR 1.55 for filing a priority claim and certified copy cannot be extended.’ This strict deadline ensures that priority claims are made promptly, allowing for efficient examination and preventing delays in the patent process. Failing to meet this deadline can result in the waiver of your priority claim, potentially affecting the patentability of your invention if intervening prior art exists. It’s essential to be aware of and adhere to this time period to protect your invention’s priority date.

What is the filing deadline for a continuation application?
A continuation application must be filed before the patenting, abandonment, or termination of proceedings on the prior application. 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.”
Key points to remember:
- There is no specific time limit for filing a continuation as long as the parent application is still pending.
- The continuation must be filed before the parent application is patented, abandoned, or otherwise terminated.
- If you want to file after the parent is patented, you must file a reissue application instead.
It’s crucial to monitor the status of the parent application closely to ensure timely filing of the continuation.

The deadline for submitting a certified copy of a foreign priority application depends on the filing date of the U.S. application. According to MPEP 213.02:
In the case of a U.S. application filed on or after March 16, 2013, the certified copy must be filed within the later of four months from the actual filing date of the application or sixteen months from the filing date of the prior foreign application.
If the certified copy is not filed within this timeframe, the applicant must file a petition to accept a delayed submission and pay the associated fee.
To learn more:
The deadline for filing a foreign priority claim in a U.S. patent application depends on the type of application:
- For applications filed under 35 U.S.C. 111(a), the claim must be filed within the later of:
- Four months from the actual filing date of the application, or
- Sixteen months from the filing date of the prior foreign application
- For international applications entering the national stage under 35 U.S.C. 371, the claim must be made within the time limit set by the PCT and its Regulations
- For design patent applications, the claim can be made at any time during the pendency of the application
As stated in MPEP 214.01: “The time periods set forth in 37 CFR 1.55(d) do not apply to design applications.”
To learn more:
For applications filed before March 16, 2013, the certified copy of the foreign application must be filed within the pendency of the application. According to 37 CFR 1.55(g)(1):
The claim for priority and the certified copy of the foreign application specified in 35 U.S.C. 119(b) or PCT Rule 17 must, in any event, be filed within the pendency of the application, unless filed with a petition under paragraph (e) or (f) of this section, or with a petition accompanied by the fee set forth in ยง 1.17(g) which includes a showing of good and sufficient cause for the delay in filing the certified copy of the foreign application in a design application.
However, it’s important to note that if the claim for priority or the certified copy is filed after the issue fee is paid, the patent will not include the priority claim unless corrected by a certificate of correction.
To learn more:
The deadline for filing a benefit claim depends on the type of application:
- For applications filed under 35 U.S.C. 111(a), the reference must be submitted within the later of:
- Four months from the actual filing date of the application, or

What happens if I miss the 12-month deadline for filing a U.S. nonprovisional application claiming priority to a foreign application?
If you miss the 12-month deadline for filing a U.S. nonprovisional application claiming priority to a foreign application, you may still be able to file the application, but you’ll lose the right to claim priority to the foreign application. The MPEP states:
“An applicant who files a nonprovisional application after the 12-month priority period (or 6-month priority period in the case of a design application) will not be able to claim priority to the foreign-filed application in the later-filed nonprovisional application.” (MPEP 213.03)
In such cases, your U.S. application will be treated as a new application without the benefit of the earlier filing date. This can have significant implications, especially if any public disclosures or other prior art have been published in the intervening time.
To learn more:
What happens if I miss the 12-month deadline for filing a nonprovisional application?
If you miss the 12-month deadline for filing a nonprovisional application claiming the benefit of a provisional application, you generally lose the ability to claim that earlier filing date. The MPEP 201.04 states:
“If a provisional application is not filed in compliance with 35 U.S.C. 119(e) and 37 CFR 1.53(c), the provisional application is not entitled to the benefit of the filing date of the provisional application.”
Consequences of missing the deadline include:
- Loss of the earlier filing date
- Potential issues with prior art that emerged during the 12-month period
- Possible loss of patent rights in some jurisdictions
In some cases, you may be able to file a petition for an unintentional delay under 37 CFR 1.78(c), but this is not guaranteed and may involve additional fees. It’s crucial to monitor deadlines carefully to avoid these issues.

What happens if I miss the 12-month deadline for filing a nonprovisional application after a provisional application?
If you miss the 12-month deadline for filing a nonprovisional application claiming the benefit of a provisional application, you lose the right to claim that benefit. The MPEP states: A provisional application is not entitled to the right of priority under 35 U.S.C. 119(e) unless the full fee set forth in 37 CFR 1.16(d) has been paid and the basic filing fee set forth in 37 CFR 1.16(a) has been paid on or before the date the provisional application was filed.
(MPEP 201.04) Additionally, you cannot extend this 12-month period. However, you may still file a nonprovisional application; it just won’t have the earlier priority date of the provisional application.

What happens if I fail to file a nonprovisional application within 12 months of my provisional application?
If you fail to file a nonprovisional application within 12 months of your provisional application’s filing date, you will lose the benefit of the provisional application’s filing date. The MPEP states:
“A provisional application expires 12 months after its filing date and cannot be revived after its expiration to restore it to pending status.” (MPEP 201.04)
This means:
- You can’t claim priority to the provisional application after the 12-month period.
- Any public disclosures made during that 12-month period may now be considered prior art against your invention.
- You may need to file a new application, potentially losing your earlier filing date.
It’s crucial to calendar the 12-month deadline and ensure timely filing of the nonprovisional application to preserve your priority date.
To learn more:
For international applications entering the national stage in the United States under 35 U.S.C. 371, the process for filing a foreign priority claim is different from regular U.S. applications. According to MPEP 214.01:
“The claim for priority must be made within the time limit set forth in the PCT and the Regulations under the PCT in an international application entering the national stage under 35 U.S.C. 371, except as provided in paragraph (e) of this section.”
This means that you need to follow the time limits specified in the Patent Cooperation Treaty (PCT) and its regulations when filing a priority claim for an international application entering the U.S. national stage.
For more detailed information on the timing and procedure for claiming priority in national stage applications, you should refer to MPEP ยง 213.06, which specifically deals with this topic.
To learn more:
No, the time period for filing a foreign priority claim cannot be extended. As stated in MPEP 214.01: “This time period is not extendable.”
However, if you miss the deadline, there is a possibility to file a petition to accept an unintentionally delayed priority claim. The MPEP states: “If a claim for priority under 35 U.S.C. 119(a)-(d) or (f), 365(a) or (b), or 386(a) or (b) is presented after the time period set in 37 CFR 1.55, the claim may be accepted if it includes the required identification information and is accompanied by a grantable petition to accept the unintentionally delayed claim for priority.”
For more information on unintentionally delayed priority claims, refer to MPEP ยง 214.02.
To learn more:
Can I file a U.S. nonprovisional application claiming priority to a provisional application after 12 months?
While it’s generally recommended to file within 12 months, there is a limited exception that allows for filing a nonprovisional application claiming priority to a provisional application after the 12-month period. The MPEP explains:
“A nonprovisional application filed not later than twelve months after the date on which the provisional application was filed … will have its filing date restored to the filing date of the provisional application for the purpose of establishing copendency with the provisional application under 35 U.S.C. 119(e).” (MPEP 213.03)
However, this exception comes with strict conditions:
- The delay in filing must have been unintentional.
- The nonprovisional application must be filed within 14 months from the provisional filing date.
- A petition to restore the right of priority must be filed promptly.
It’s important to note that this exception is not automatic and requires a petition process. If granted, it allows the nonprovisional application to claim the benefit of the provisional application’s filing date.
To learn more:
Yes, design patent applications have different requirements for filing priority claims compared to utility patent applications. The main difference is in the time period for filing the claim. As stated in MPEP 214.01:
“The time periods set forth in 37 CFR 1.55(d) do not apply to design applications.”
For design applications, the MPEP further clarifies: “In a design application, a claim for priority may be made at any time during the pendency of the application. See 37 CFR 1.55(g).”
This means that for design patent applications, you can file a priority claim at any time while the application is pending, which provides more flexibility compared to utility patent applications.
For more detailed information on priority claims in design applications, you can refer to MPEP ยง 1504.10 and MPEP ยง 2920.05(d).

See MPEP 215.02.
For an international application entering the national stage under 35 U.S.C. 371 in which the national stage commenced on or after December 18, 2013, a certified copy of the foreign application must be filed within the later of four months from the date on which the national stage commenced under 35 U.S.C. 371(b) or (f), four months from the date of the initial submission under 35 U.S.C. 371 to enter the national stage, or sixteen months from the filing date of the prior foreign application, except as provided in 37 CFR 1.55(h), (i), and (j). See MPEP 215.02.
A certified copy of a foreign application is an official copy of the foreign patent application, certified by the patent office where it was filed. It is required to perfect a claim of foreign priority in a U.S. patent application.
According to 37 CFR 1.55(f), for applications filed on or after March 16, 2013:
“A certified copy of the foreign application must be filed within the later of four months from the actual filing date of the application, or sixteen months from the filing date of the prior foreign application, in an original application under 35 U.S.C. 111(a) filed on or after March 16, 2013, except as provided in paragraphs (h), (i), and (j) of this section.”
There are exceptions to this requirement, such as when the foreign application was filed in a foreign intellectual property office participating in a priority document exchange agreement with the USPTO. In such cases, the applicant can request that the USPTO retrieve the certified copy electronically.
Yes, it is possible to restore the right of priority if you miss the 12-month filing deadline (6 months for design applications). As provided in 37 CFR 1.55(c), if the subsequent application is filed within two months from the expiration of the priority period, the right of priority may be restored upon petition. The petition must include:
- The priority claim (unless previously submitted)
- The petition fee
- A statement that the delay in filing was unintentional
The Director may require additional information where there is a question whether the delay was unintentional. Note that while this allows for a valid priority claim, it does not overcome potential prior art issues under pre-AIA 35 U.S.C. 102(b) or (d) in applications subject to pre-AIA law.
MPEP 201 - Types of Applications (3)
What is the time limit for filing a divisional application?
There is no specific time limit for filing a divisional application, but there are important considerations that effectively create a practical time frame:
- Parent Application Status: The divisional application must be filed while the parent application is still pending. Once the parent application is either abandoned or issued as a patent, it’s no longer possible to file a divisional from it.
- Priority Claim: To claim the benefit of the parent application’s filing date, the divisional must be filed within the time periods specified in 35 U.S.C. 120, 121, 365(c), or 386(c).
- Patent Term: The 20-year patent term is calculated from the earliest non-provisional U.S. filing date. Filing a divisional later in the parent’s pendency will result in a shorter potential patent term for the divisional.
The MPEP 201.06 states:
A divisional application is often filed as a result of a restriction requirement made by the examiner.
While this doesn’t specify a time limit, it implies that divisional applications are typically filed in response to office actions during the examination process. Applicants should consider filing a divisional promptly after receiving a restriction requirement to ensure they don’t miss any deadlines and to maximize the potential patent term.

What is the filing deadline for a continuation application?
A continuation application must be filed before the patenting, abandonment, or termination of proceedings on the prior application. 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.”
Key points to remember:
- There is no specific time limit for filing a continuation as long as the parent application is still pending.
- The continuation must be filed before the parent application is patented, abandoned, or otherwise terminated.
- If you want to file after the parent is patented, you must file a reissue application instead.
It’s crucial to monitor the status of the parent application closely to ensure timely filing of the continuation.

The time limit for filing a U.S. nonprovisional application claiming priority to a foreign application is generally 12 months from the filing date of the foreign application. For design applications, the time limit is 6 months.
As stated in the MPEP, The United States nonprovisional application must be filed not later than twelve months (six months in the case of a design application) after the date on which the foreign application was filed, unless the right of priority has been restored.
(MPEP 213.03)
It’s important to note that this period is subject to certain provisions, such as the extension to the next business day if the deadline falls on a weekend or federal holiday.

What is the time limit for filing a substitute statement?
A substitute statement must be filed within the time period set forth in 37 CFR 1.53(f) or 1.53(d), as applicable. According to MPEP 604:
“The Office has revised the rules to permit applicants to postpone filing an inventor’s oath or declaration until the application is otherwise in condition for allowance if the applicant provides an application data sheet indicating the name, residence, and mailing address of each inventor.”
This means that while you can postpone filing the substitute statement, it must be submitted before the application is allowed. It’s important to note that the substitute statement is subject to the same time constraints as the inventor’s oath or declaration.

What is the time limit for filing a divisional application?
There is no specific time limit for filing a divisional application, but there are important considerations that effectively create a practical time frame:
- Parent Application Status: The divisional application must be filed while the parent application is still pending. Once the parent application is either abandoned or issued as a patent, it’s no longer possible to file a divisional from it.
- Priority Claim: To claim the benefit of the parent application’s filing date, the divisional must be filed within the time periods specified in 35 U.S.C. 120, 121, 365(c), or 386(c).
- Patent Term: The 20-year patent term is calculated from the earliest non-provisional U.S. filing date. Filing a divisional later in the parent’s pendency will result in a shorter potential patent term for the divisional.
The MPEP 201.06 states:
A divisional application is often filed as a result of a restriction requirement made by the examiner.
While this doesn’t specify a time limit, it implies that divisional applications are typically filed in response to office actions during the examination process. Applicants should consider filing a divisional promptly after receiving a restriction requirement to ensure they don’t miss any deadlines and to maximize the potential patent term.

For applications filed under 35 U.S.C. 111(a) on or after March 16, 2013, 37 CFR 1.55(f)(1) requires that a certified copy of the foreign application be filed within the later of:
- Four months from the actual filing date of the application, or
- Sixteen months from the filing date of the prior foreign application
This time period does not apply to design applications. There are three exceptions to this requirement, as outlined in 37 CFR 1.55(h), (i), and (j).

What is the significance of the ‘time period set in 37 CFR 1.55’ for filing priority claims?
The time period set in 37 CFR 1.55 is crucial for securing your priority claim in a patent application. MPEP 213.04 states: ‘The time period set in 37 CFR 1.55 for filing a priority claim and certified copy cannot be extended.’ This strict deadline ensures that priority claims are made promptly, allowing for efficient examination and preventing delays in the patent process. Failing to meet this deadline can result in the waiver of your priority claim, potentially affecting the patentability of your invention if intervening prior art exists. It’s essential to be aware of and adhere to this time period to protect your invention’s priority date.

What is the filing deadline for a continuation application?
A continuation application must be filed before the patenting, abandonment, or termination of proceedings on the prior application. 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.”
Key points to remember:
- There is no specific time limit for filing a continuation as long as the parent application is still pending.
- The continuation must be filed before the parent application is patented, abandoned, or otherwise terminated.
- If you want to file after the parent is patented, you must file a reissue application instead.
It’s crucial to monitor the status of the parent application closely to ensure timely filing of the continuation.

A certified copy of a foreign application is an official copy of the foreign patent application, certified by the patent office where it was filed. It is required to perfect a claim of foreign priority in a U.S. patent application.
According to 37 CFR 1.55(f), for applications filed on or after March 16, 2013:
“A certified copy of the foreign application must be filed within the later of four months from the actual filing date of the application, or sixteen months from the filing date of the prior foreign application, in an original application under 35 U.S.C. 111(a) filed on or after March 16, 2013, except as provided in paragraphs (h), (i), and (j) of this section.”
There are exceptions to this requirement, such as when the foreign application was filed in a foreign intellectual property office participating in a priority document exchange agreement with the USPTO. In such cases, the applicant can request that the USPTO retrieve the certified copy electronically.
What happens if I miss the 12-month deadline for filing a U.S. nonprovisional application claiming priority to a foreign application?
If you miss the 12-month deadline for filing a U.S. nonprovisional application claiming priority to a foreign application, you may still be able to file the application, but you’ll lose the right to claim priority to the foreign application. The MPEP states:
“An applicant who files a nonprovisional application after the 12-month priority period (or 6-month priority period in the case of a design application) will not be able to claim priority to the foreign-filed application in the later-filed nonprovisional application.” (MPEP 213.03)
In such cases, your U.S. application will be treated as a new application without the benefit of the earlier filing date. This can have significant implications, especially if any public disclosures or other prior art have been published in the intervening time.
To learn more:
What happens if I miss the 12-month deadline for filing a nonprovisional application?
If you miss the 12-month deadline for filing a nonprovisional application claiming the benefit of a provisional application, you generally lose the ability to claim that earlier filing date. The MPEP 201.04 states:
“If a provisional application is not filed in compliance with 35 U.S.C. 119(e) and 37 CFR 1.53(c), the provisional application is not entitled to the benefit of the filing date of the provisional application.”
Consequences of missing the deadline include:
- Loss of the earlier filing date
- Potential issues with prior art that emerged during the 12-month period
- Possible loss of patent rights in some jurisdictions
In some cases, you may be able to file a petition for an unintentional delay under 37 CFR 1.78(c), but this is not guaranteed and may involve additional fees. It’s crucial to monitor deadlines carefully to avoid these issues.

What happens if I miss the 12-month deadline for filing a nonprovisional application after a provisional application?
If you miss the 12-month deadline for filing a nonprovisional application claiming the benefit of a provisional application, you lose the right to claim that benefit. The MPEP states: A provisional application is not entitled to the right of priority under 35 U.S.C. 119(e) unless the full fee set forth in 37 CFR 1.16(d) has been paid and the basic filing fee set forth in 37 CFR 1.16(a) has been paid on or before the date the provisional application was filed.
(MPEP 201.04) Additionally, you cannot extend this 12-month period. However, you may still file a nonprovisional application; it just won’t have the earlier priority date of the provisional application.

What happens if I fail to file a priority claim within the time period set in 37 CFR 1.55?
If you fail to file a priority claim within the time period set in 37 CFR 1.55, your priority claim will be considered waived. The MPEP states: ‘If the claim for priority or the certified copy of the foreign application is filed after the date the issue fee is paid, the patent will not include the priority claim unless corrected by a certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323.’ This means that if you miss the deadline, you may lose the benefit of the earlier filing date, which could potentially affect the patentability of your invention if intervening prior art exists.

What happens if I fail to file a nonprovisional application within 12 months of my provisional application?
If you fail to file a nonprovisional application within 12 months of your provisional application’s filing date, you will lose the benefit of the provisional application’s filing date. The MPEP states:
“A provisional application expires 12 months after its filing date and cannot be revived after its expiration to restore it to pending status.” (MPEP 201.04)
This means:
- You can’t claim priority to the provisional application after the 12-month period.
- Any public disclosures made during that 12-month period may now be considered prior art against your invention.
- You may need to file a new application, potentially losing your earlier filing date.
It’s crucial to calendar the 12-month deadline and ensure timely filing of the nonprovisional application to preserve your priority date.

For international applications entering the national stage in the United States under 35 U.S.C. 371, the process for filing a foreign priority claim is different from regular U.S. applications. According to MPEP 214.01:
“The claim for priority must be made within the time limit set forth in the PCT and the Regulations under the PCT in an international application entering the national stage under 35 U.S.C. 371, except as provided in paragraph (e) of this section.”
This means that you need to follow the time limits specified in the Patent Cooperation Treaty (PCT) and its regulations when filing a priority claim for an international application entering the U.S. national stage.
For more detailed information on the timing and procedure for claiming priority in national stage applications, you should refer to MPEP ยง 213.06, which specifically deals with this topic.
To learn more:
No, the time period for filing a foreign priority claim cannot be extended. As stated in MPEP 214.01: “This time period is not extendable.”
However, if you miss the deadline, there is a possibility to file a petition to accept an unintentionally delayed priority claim. The MPEP states: “If a claim for priority under 35 U.S.C. 119(a)-(d) or (f), 365(a) or (b), or 386(a) or (b) is presented after the time period set in 37 CFR 1.55, the claim may be accepted if it includes the required identification information and is accompanied by a grantable petition to accept the unintentionally delayed claim for priority.”
For more information on unintentionally delayed priority claims, refer to MPEP ยง 214.02.
To learn more:
Yes, it is possible to restore the right of priority if you miss the 12-month filing deadline (6 months for design applications). As provided in 37 CFR 1.55(c), if the subsequent application is filed within two months from the expiration of the priority period, the right of priority may be restored upon petition. The petition must include:
- The priority claim (unless previously submitted)
- The petition fee
- A statement that the delay in filing was unintentional
The Director may require additional information where there is a question whether the delay was unintentional. Note that while this allows for a valid priority claim, it does not overcome potential prior art issues under pre-AIA 35 U.S.C. 102(b) or (d) in applications subject to pre-AIA law.
Can I file a U.S. nonprovisional application claiming priority to a provisional application after 12 months?
While it’s generally recommended to file within 12 months, there is a limited exception that allows for filing a nonprovisional application claiming priority to a provisional application after the 12-month period. The MPEP explains:
“A nonprovisional application filed not later than twelve months after the date on which the provisional application was filed … will have its filing date restored to the filing date of the provisional application for the purpose of establishing copendency with the provisional application under 35 U.S.C. 119(e).” (MPEP 213.03)
However, this exception comes with strict conditions:
- The delay in filing must have been unintentional.
- The nonprovisional application must be filed within 14 months from the provisional filing date.
- A petition to restore the right of priority must be filed promptly.
It’s important to note that this exception is not automatic and requires a petition process. If granted, it allows the nonprovisional application to claim the benefit of the provisional application’s filing date.
To learn more:
Yes, design patent applications have different requirements for filing priority claims compared to utility patent applications. The main difference is in the time period for filing the claim. As stated in MPEP 214.01:
“The time periods set forth in 37 CFR 1.55(d) do not apply to design applications.”
For design applications, the MPEP further clarifies: “In a design application, a claim for priority may be made at any time during the pendency of the application. See 37 CFR 1.55(g).”
This means that for design patent applications, you can file a priority claim at any time while the application is pending, which provides more flexibility compared to utility patent applications.
For more detailed information on priority claims in design applications, you can refer to MPEP ยง 1504.10 and MPEP ยง 2920.05(d).

If you miss the 12-month deadline for filing a U.S. nonprovisional application claiming priority to a foreign application, you may still be able to file the application, but you’ll lose the right to claim priority to the foreign application. The MPEP states:
“An applicant who files a nonprovisional application after the 12-month priority period (or 6-month priority period in the case of a design application) will not be able to claim priority to the foreign-filed application in the later-filed nonprovisional application.” (MPEP 213.03)
In such cases, your U.S. application will be treated as a new application without the benefit of the earlier filing date. This can have significant implications, especially if any public disclosures or other prior art have been published in the intervening time.

What happens if I miss the 12-month deadline for filing a nonprovisional application?
If you miss the 12-month deadline for filing a nonprovisional application claiming the benefit of a provisional application, you generally lose the ability to claim that earlier filing date. The MPEP 201.04 states:
“If a provisional application is not filed in compliance with 35 U.S.C. 119(e) and 37 CFR 1.53(c), the provisional application is not entitled to the benefit of the filing date of the provisional application.”
Consequences of missing the deadline include:
- Loss of the earlier filing date
- Potential issues with prior art that emerged during the 12-month period
- Possible loss of patent rights in some jurisdictions
In some cases, you may be able to file a petition for an unintentional delay under 37 CFR 1.78(c), but this is not guaranteed and may involve additional fees. It’s crucial to monitor deadlines carefully to avoid these issues.

What happens if I miss the 12-month deadline for filing a nonprovisional application after a provisional application?
If you miss the 12-month deadline for filing a nonprovisional application claiming the benefit of a provisional application, you lose the right to claim that benefit. The MPEP states: A provisional application is not entitled to the right of priority under 35 U.S.C. 119(e) unless the full fee set forth in 37 CFR 1.16(d) has been paid and the basic filing fee set forth in 37 CFR 1.16(a) has been paid on or before the date the provisional application was filed.
(MPEP 201.04) Additionally, you cannot extend this 12-month period. However, you may still file a nonprovisional application; it just won’t have the earlier priority date of the provisional application.

What happens if I fail to file a priority claim within the time period set in 37 CFR 1.55?
If you fail to file a priority claim within the time period set in 37 CFR 1.55, your priority claim will be considered waived. The MPEP states: ‘If the claim for priority or the certified copy of the foreign application is filed after the date the issue fee is paid, the patent will not include the priority claim unless corrected by a certificate of correction under 35 U.S.C. 255 and 37 CFR 1.323.’ This means that if you miss the deadline, you may lose the benefit of the earlier filing date, which could potentially affect the patentability of your invention if intervening prior art exists.

What happens if I fail to file a nonprovisional application within 12 months of my provisional application?
If you fail to file a nonprovisional application within 12 months of your provisional application’s filing date, you will lose the benefit of the provisional application’s filing date. The MPEP states:
“A provisional application expires 12 months after its filing date and cannot be revived after its expiration to restore it to pending status.” (MPEP 201.04)
This means:
- You can’t claim priority to the provisional application after the 12-month period.
- Any public disclosures made during that 12-month period may now be considered prior art against your invention.
- You may need to file a new application, potentially losing your earlier filing date.
It’s crucial to calendar the 12-month deadline and ensure timely filing of the nonprovisional application to preserve your priority date.

For international applications entering the national stage in the United States under 35 U.S.C. 371, the process for filing a foreign priority claim is different from regular U.S. applications. According to MPEP 214.01:
“The claim for priority must be made within the time limit set forth in the PCT and the Regulations under the PCT in an international application entering the national stage under 35 U.S.C. 371, except as provided in paragraph (e) of this section.”
This means that you need to follow the time limits specified in the Patent Cooperation Treaty (PCT) and its regulations when filing a priority claim for an international application entering the U.S. national stage.
For more detailed information on the timing and procedure for claiming priority in national stage applications, you should refer to MPEP ยง 213.06, which specifically deals with this topic.

No, the time period for filing a foreign priority claim cannot be extended. As stated in MPEP 214.01: “This time period is not extendable.”
However, if you miss the deadline, there is a possibility to file a petition to accept an unintentionally delayed priority claim. The MPEP states: “If a claim for priority under 35 U.S.C. 119(a)-(d) or (f), 365(a) or (b), or 386(a) or (b) is presented after the time period set in 37 CFR 1.55, the claim may be accepted if it includes the required identification information and is accompanied by a grantable petition to accept the unintentionally delayed claim for priority.”
For more information on unintentionally delayed priority claims, refer to MPEP ยง 214.02.

Yes, it is possible to restore the right of priority if you miss the 12-month filing deadline (6 months for design applications). As provided in 37 CFR 1.55(c), if the subsequent application is filed within two months from the expiration of the priority period, the right of priority may be restored upon petition. The petition must include:
- The priority claim (unless previously submitted)
- The petition fee
- A statement that the delay in filing was unintentional
The Director may require additional information where there is a question whether the delay was unintentional. Note that while this allows for a valid priority claim, it does not overcome potential prior art issues under pre-AIA 35 U.S.C. 102(b) or (d) in applications subject to pre-AIA law.
Can I file a U.S. nonprovisional application claiming priority to a provisional application after 12 months?
While it’s generally recommended to file within 12 months, there is a limited exception that allows for filing a nonprovisional application claiming priority to a provisional application after the 12-month period. The MPEP explains:
“A nonprovisional application filed not later than twelve months after the date on which the provisional application was filed … will have its filing date restored to the filing date of the provisional application for the purpose of establishing copendency with the provisional application under 35 U.S.C. 119(e).” (MPEP 213.03)
However, this exception comes with strict conditions:
- The delay in filing must have been unintentional.
- The nonprovisional application must be filed within 14 months from the provisional filing date.
- A petition to restore the right of priority must be filed promptly.
It’s important to note that this exception is not automatic and requires a petition process. If granted, it allows the nonprovisional application to claim the benefit of the provisional application’s filing date.

Yes, design patent applications have different requirements for filing priority claims compared to utility patent applications. The main difference is in the time period for filing the claim. As stated in MPEP 214.01:
“The time periods set forth in 37 CFR 1.55(d) do not apply to design applications.”
For design applications, the MPEP further clarifies: “In a design application, a claim for priority may be made at any time during the pendency of the application. See 37 CFR 1.55(g).”
This means that for design patent applications, you can file a priority claim at any time while the application is pending, which provides more flexibility compared to utility patent applications.
For more detailed information on priority claims in design applications, you can refer to MPEP ยง 1504.10 and MPEP ยง 2920.05(d).
