MPEP 200 - Types and Status of Application; Benefit and Priority (11)

For amended patent applications, it’s important to understand the expected timelines and when it’s appropriate to make a status inquiry:

  • Examiners are expected to act on amended applications within two months of receiving them.
  • A status inquiry is generally not necessary until 5-6 months have passed without a response from the USPTO.
  • If six months elapse without a response, you should inquire to avoid potential abandonment.

The MPEP advises: Amended applications are expected to be taken up by the examiner and an action completed within two months of the date the examiner receives the application. Accordingly, a status inquiry is not in order after reply by the attorney until 5 or 6 months have elapsed with no response from the Office. (MPEP 203.08)

It further states: However, in the event that a six month period has elapsed, and no response from the Office is received, applicant should inquire as to the status of the application to avoid potential abandonment.

For making inquiries, the MPEP recommends: Applicants are encouraged to use Patent Center or Private PAIR to make status inquiries.

To learn more:

The status of an application as ‘allowed’ has a specific timeframe. According to the MPEP:

“Its status as an ‘allowed’ application continues from the date of the notice of allowance until it issues as a patent, unless it is withdrawn from issue ( 37 CFR 1.313 ), or becomes abandoned for failure to pay the issue fee and any required publication fee ( 37 CFR 1.314 and 1.316 ).”

In other words, the ‘allowed’ status begins when the notice of allowance is sent and typically ends when the patent is issued. However, this status can be terminated if the application is withdrawn from issue or becomes abandoned due to non-payment of required fees.

What happens to the prior application when a CPA is filed?

When a Continued Prosecution Application (CPA) is filed, the prior application is automatically abandoned. According to MPEP 201.06(d):

The filing of a CPA is not a filing of a new application. Rather, a CPA is a continuation of the prior application and maintains the same application number as the prior application, i.e., a “streeting” of the prior application.

This means that:

  • The prior application is considered abandoned as of the filing date of the CPA.
  • The CPA is not assigned a new application number but continues under the number of the prior application.
  • All correspondence for the CPA should refer to the original application number.

It’s important to note that this automatic abandonment of the prior application is a key feature of CPA practice, distinguishing it from other types of continuing applications.

If the required translation or statement is missing for a non-English provisional application, the following consequences apply:

  1. The USPTO will issue a notice stating that the required documents are missing.
  2. The applicant must supply the missing translation and/or statement in the provisional application.
  3. The applicant must provide confirmation in the present application that the translation and statement were filed in the provisional application.
  4. If these requirements are not met within the time period set by the USPTO, the present application will be abandoned.

As stated in the MPEP, If 1) and 2) are not filed (or if the benefit claim is not withdrawn) prior to the expiration of the time period set in this Office action, the present application will be abandoned. See 37 CFR 1.78.

If the required translation and statement are not filed for a non-English provisional application, serious consequences can occur. According to MPEP ยถ 2.38:

“If 1) and 2) are not filed (or if the benefit claim is not withdrawn) prior to the expiration of the time period set in this Office action, the present application will be abandoned.”

This means that if you fail to provide the English translation and accuracy statement in the provisional application, and fail to confirm their filing in the present application, your current application may be abandoned. It’s crucial to comply with these requirements within the specified time frame to maintain your application’s active status.

What happens if I file a provisional application and don’t file a nonprovisional within 12 months?

If you file a provisional application but do not file a corresponding nonprovisional application within 12 months, the provisional application will automatically be abandoned. As stated in the MPEP 201.04: “A provisional application will automatically be abandoned 12 months after its filing date and will not be subject to revival to restore it to pending status thereafter.” This means you lose the benefit of the provisional filing date and cannot claim priority to it in future applications. To maintain the priority benefit, you must file a nonprovisional application claiming benefit of the provisional within the 12-month period.

If you don’t pay the issue fee for your patent application, it will be considered abandoned. According to MPEP 203.05, one of the ways an application can become abandoned is:

“for failure to pay the issue fee”

The MPEP refers to sections 711 to 711.05 for more details on this topic. It’s crucial to pay the issue fee on time to prevent your application from being abandoned after all the effort put into the patent prosecution process.

To learn more:

To maintain an allowed application’s status and proceed to patent issuance, certain fees must be paid. The MPEP mentions two specific fees:

  1. Issue fee: This is the fee required for the USPTO to issue the patent.
  2. Publication fee: If applicable, this fee covers the cost of publishing the patent application.

The MPEP states that an application becomes abandoned “for failure to pay the issue fee and any required publication fee ( 37 CFR 1.314 and 1.316 ).” Therefore, timely payment of these fees is crucial to maintain the allowed status and proceed to patent issuance.

To learn more:

An allowed application can lose its status under certain circumstances. The MPEP outlines two main scenarios:

  1. Withdrawal from issue: This is governed by 37 CFR 1.313. The applicant or the USPTO may initiate this process for various reasons, such as the need for further examination or the discovery of new prior art.
  2. Abandonment due to non-payment: As stated in the MPEP, an application becomes abandoned “for failure to pay the issue fee and any required publication fee ( 37 CFR 1.314 and 1.316 ).”

In either case, the application loses its ‘allowed’ status and may require further action or payments to proceed towards patent issuance.

To learn more:

Filing a Continued Prosecution Application (CPA) has a significant effect on the prior application. According to the MPEP, A request for a CPA expressly abandons the prior application as of the filing date of the request for the CPA. This means that when you file a CPA, the previous application is automatically abandoned in favor of the new CPA. The CPA will use the file wrapper and contents of the prior application, including the specification, drawings, and oath or declaration, and will be assigned the same application number as the prior application.

  1. The USPTO will issue a notice stating that the required documents are missing.
  2. The applicant must supply the missing translation and/or statement in the provisional application.
  3. The applicant must provide confirmation in the present application that the translation and statement were filed in the provisional application.
  4. If these requirements are not met within the time period set by the USPTO, the present application will be abandoned.

As stated in the MPEP, If 1) and 2) are not filed (or if the benefit claim is not withdrawn) prior to the expiration of the time period set in this Office action, the present application will be abandoned. See 37 CFR 1.78.

MPEP 400 - Representative of Applicant or Owner (2)

If a patent application is filed without a correspondence address:

  • The USPTO needs a correspondence address to notify the applicant of any missing parts or requirements.
  • If no address is provided, the Office may use the mailing address of the first named inventor as the correspondence address.
  • Without a correspondence address, the applicant is considered to have constructive notice of application requirements as of the filing date.
  • The applicant has 2 months from the filing date to complete the application before it is abandoned.

According to MPEP 403: “If a patent application as filed has been accorded a filing date but is not complete, the applicant is notified and given a period of time within which to file the missing parts to complete the application and pay the applicable surcharge. … If the applicant fails to provide the Office with a correspondence address, the Office will be unable to provide the applicant with notification to complete the application and to pay the surcharge as set forth in 37 CFR 1.16(f) for nonprovisional applications and 37 CFR 1.16(g) for provisional applications. In such a case, the applicant will be considered to have constructive notice as of the filing date that the application must be completed and the applicant will have 2 months from the filing date in which to do so before abandonment occurs.”

According to MPEP 406, when the USPTO notifies an applicant of their patent practitioner’s death, the applicant is given a specific timeframe to respond. The MPEP states:

“The period for reply to such a notice is normally set at 3 months.”

During this 3-month period, the applicant must take one of the following actions:

  • Appoint a new registered patent practitioner
  • File a change of correspondence address

It’s crucial to respond within this timeframe to prevent the application from being deemed abandoned.

MPEP 403 - Correspondence โ€” With Whom Held; Customer Number Practice (1)

If a patent application is filed without a correspondence address:

  • The USPTO needs a correspondence address to notify the applicant of any missing parts or requirements.
  • If no address is provided, the Office may use the mailing address of the first named inventor as the correspondence address.
  • Without a correspondence address, the applicant is considered to have constructive notice of application requirements as of the filing date.
  • The applicant has 2 months from the filing date to complete the application before it is abandoned.

According to MPEP 403: “If a patent application as filed has been accorded a filing date but is not complete, the applicant is notified and given a period of time within which to file the missing parts to complete the application and pay the applicable surcharge. … If the applicant fails to provide the Office with a correspondence address, the Office will be unable to provide the applicant with notification to complete the application and to pay the surcharge as set forth in 37 CFR 1.16(f) for nonprovisional applications and 37 CFR 1.16(g) for provisional applications. In such a case, the applicant will be considered to have constructive notice as of the filing date that the application must be completed and the applicant will have 2 months from the filing date in which to do so before abandonment occurs.”

MPEP 406 - Death of Patent Practitioner (1)

According to MPEP 406, when the USPTO notifies an applicant of their patent practitioner’s death, the applicant is given a specific timeframe to respond. The MPEP states:

“The period for reply to such a notice is normally set at 3 months.”

During this 3-month period, the applicant must take one of the following actions:

  • Appoint a new registered patent practitioner
  • File a change of correspondence address

MPEP 500 - Receipt and Handling of Mail and Papers (3)

If a nonprovisional patent application is filed without all required fees, the USPTO will send a notice to the applicant. According to the MPEP:

Filing dates are accorded to nonprovisional applications filed under 37 CFR 1.53(b) submitted without the… required fees (basic filing fee, and search and examination fees (for applications filed on or after December 8, 2004))… In such cases, a notice is mailed by OPAP requiring the appropriate fees… accompanied by a surcharge (37 CFR 1.16(f)).

The applicant will be given a time period (usually two months) to pay the missing fees and surcharge to avoid abandonment of the application.

The consequences of failing to respond to a 37 CFR 1.251 notice differ for pending applications and granted patents:

  • For pending applications: Failure to reply within the set time period will result in abandonment of the application. MPEP 508.04 cites 37 CFR 1.251(b): “With regard to a pending application, failure to comply with one of paragraphs (a)(1), (a)(2), or (a)(3) of this section within the time period set in the notice will result in abandonment of the application.”
  • For granted patents: While the patent won’t expire, there may be limitations on the certified copy of the patent file that the Office can produce. MPEP 508.04 states: “While abandonment (or expiration) of a patent is not an issue if a patentee fails to timely comply with a notice under 37 CFR 1.251, in such a situation the only certified copy of the patent file that the Office will be able to produce will be a copy of the patent and a copy of the application-as-filed (which may have an adverse impact during attempts to enforce the patent).”

Additionally, for patents involved in proceedings before the Office, action may be taken under 37 CFR 41.128 or 37 CFR 11.18.

Once a patent application is filed and given a filing date, it generally cannot be returned or withdrawn. According to MPEP 503:

“Applications which are entitled to a filing date, whether filed by regular mail, by Priority Mail Expressยฎ under 37 CFR 1.10, by hand-delivery, by the USPTO patent electronic filing system, or otherwise, will not be returned to applicant even if requested.”

This policy is in place to maintain the integrity of the filing process and prevent potential abuse. Applicants should be careful not to file applications that are not intended to be filed, such as duplicates of already filed applications.

Furthermore, the MPEP cites 37 CFR 1.26(a), which states that a change of purpose after payment of a fee, such as when a party desires to withdraw a patent application for which a fee was paid, does not entitle the party to a refund of such fee.

If an applicant realizes they have filed an application in error or no longer wish to pursue it, they may choose to abandon the application. However, the application will remain on file with the USPTO and any fees paid will not be refunded.

MPEP 506 - Completeness of Original Application (1)

If a nonprovisional patent application is filed without all required fees, the USPTO will send a notice to the applicant. According to the MPEP:

Filing dates are accorded to nonprovisional applications filed under 37 CFR 1.53(b) submitted without the… required fees (basic filing fee, and search and examination fees (for applications filed on or after December 8, 2004))… In such cases, a notice is mailed by OPAP requiring the appropriate fees… accompanied by a surcharge (37 CFR 1.16(f)).

The applicant will be given a time period (usually two months) to pay the missing fees and surcharge to avoid abandonment of the application.

MPEP 508 - Distribution (1)

The consequences of failing to respond to a 37 CFR 1.251 notice differ for pending applications and granted patents:

  • For pending applications: Failure to reply within the set time period will result in abandonment of the application. MPEP 508.04 cites 37 CFR 1.251(b): “With regard to a pending application, failure to comply with one of paragraphs (a)(1), (a)(2), or (a)(3) of this section within the time period set in the notice will result in abandonment of the application.”
  • For granted patents: While the patent won’t expire, there may be limitations on the certified copy of the patent file that the Office can produce.

What happens if the basic national fee is not paid on time for US national stage entry?

If the basic national fee is not paid on time for US national stage entry, the application will be considered abandoned. However, the MPEP provides guidance on potential remedies:

If the basic national fee is not paid on time, the Designated (or Elected) Office will declare that the application is considered withdrawn under PCT Article 24(1) or 39(2). However, if the basic national fee is paid later, accompanied by a petition for revival, the Designated (or Elected) Office may excuse the late payment of the basic national fee.

This means that while timely payment is crucial, there may be options to revive the application if the fee is paid late. Applicants should be aware that such petitions typically involve additional fees and are subject to specific requirements and time limits.

To learn more:

What happens if I file a provisional application and don’t file a nonprovisional within 12 months?

If you file a provisional application but do not file a corresponding nonprovisional application within 12 months, the provisional application will automatically be abandoned. As stated in the MPEP 201.04: “A provisional application will automatically be abandoned 12 months after its filing date and will not be subject to revival to restore it to pending status thereafter.” This means you lose the benefit of the provisional filing date and cannot claim priority to it in future applications. To maintain the priority benefit, you must file a nonprovisional application claiming benefit of the provisional within the 12-month period.

If drawings are not timely filed in response to a notice from the USPTO or a letter from the examiner requiring a drawing, the consequences are severe:

  • The application becomes abandoned for failure to reply.

The MPEP clearly states: If a drawing is not timely received in reply to a notice from the Office or a letter from the examiner who requires a drawing, the application becomes abandoned for failure to reply.

This underscores the importance of promptly responding to USPTO notices and examiner requirements regarding drawings. For information on handling replacement drawings, refer to MPEP ยง 608.02(h).

To learn more:

If an applicant fails to submit required application components within the specified time period, the following consequences may occur:

  • The application may be considered abandoned.
  • If abandoned, the application will be treated as though it had never been filed.
  • The applicant may lose the benefit of the original filing date.

The MPEP states: Upon failure to submit the fee, oath or declaration, and 1 or more claims within such prescribed period, the application shall be regarded as abandoned.

However, it may be possible to revive an abandoned application under certain circumstances:

  • The applicant can file a petition to revive under 37 CFR 1.137.
  • The petition must be accompanied by the required reply, the petition fee, and a statement that the entire delay was unintentional.

It’s crucial to respond to any notices from the USPTO promptly and to submit all required components within the specified timeframes to avoid these issues.

If a patent application is filed without a correspondence address:

  • The USPTO needs a correspondence address to notify the applicant of any missing parts or requirements.
  • If no address is provided, the Office may use the mailing address of the first named inventor as the correspondence address.
  • Without a correspondence address, the applicant is considered to have constructive notice of application requirements as of the filing date.
  • The applicant has 2 months from the filing date to complete the application before it is abandoned.

According to MPEP 403: “If a patent application as filed has been accorded a filing date but is not complete, the applicant is notified and given a period of time within which to file the missing parts to complete the application and pay the applicable surcharge. … If the applicant fails to provide the Office with a correspondence address, the Office will be unable to provide the applicant with notification to complete the application and to pay the surcharge as set forth in 37 CFR 1.16(f) for nonprovisional applications and 37 CFR 1.16(g) for provisional applications. In such a case, the applicant will be considered to have constructive notice as of the filing date that the application must be completed and the applicant will have 2 months from the filing date in which to do so before abandonment occurs.”

If a nonprovisional patent application is filed without all required fees, the USPTO will send a notice to the applicant. According to the MPEP:

  1. Withdrawal from issue: This is governed by 37 CFR 1.313. The applicant or the USPTO may initiate this process for various reasons, such as the need for further examination or the discovery of new prior art.
  2. Abandonment due to non-payment: As stated in the MPEP, an application becomes abandoned “for failure to pay the issue fee and any required publication fee ( 37 CFR 1.314 and 1.316 ).”

In either case, the application loses its ‘allowed’ status and may require further action or payments to proceed towards patent issuance.

The MPEP 602.08(c) warns about a serious potential consequence of misidentifying an application:

Further an oath or declaration attached to a cover letter referencing an incorrect application may not become associated with the correct application and, therefore, could result in the abandonment of the correct application.

This means that if you submit an oath or declaration with a cover letter that references the wrong application number or details, it might not be properly associated with the intended application. As a result, the correct application could be considered abandoned due to lack of a proper oath or declaration.

To avoid this issue, it’s crucial to double-check all application identifiers and ensure that cover letters, oaths, and declarations accurately reference the intended application. If you discover such an error, you should contact the USPTO promptly to rectify the situation and prevent unintended abandonment.

What are the consequences of omitting an inventor’s oath or declaration in a nonprovisional application?

Omitting an inventor’s oath or declaration in a nonprovisional application can have significant consequences. According to MPEP 601.01(a):

If the application is filed without an inventor’s oath or declaration by any inventor, the Office will send a Notice to File Missing Parts giving the applicant a time period (usually two months) within which to file the missing oath or declaration and to pay the surcharge required by 37 CFR 1.16(f) to avoid abandonment.

The key points to note are:

  • The USPTO will send a Notice to File Missing Parts.
  • A time period (usually two months) is given to file the missing oath or declaration.
  • A surcharge under 37 CFR 1.16(f) must be paid.
  • Failure to comply may result in abandonment of the application.

It’s important to note that while the application can be filed without the oath or declaration, it must be submitted before the application is allowed to avoid potential issues.

For more information, refer to MPEP 601.01(a) and MPEP 602 on inventor’s oath or declaration.

To learn more:

Failing to submit an inventor’s oath or declaration before the issue fee is paid can have serious consequences for a patent application. According to MPEP 602.01(a):

If an application does not include an oath or declaration by the inventor or a substitute statement, the Office will issue a notice requiring the applicant to file the inventor’s oath or declaration no later than the date on which the issue fee is paid.

The consequences of not complying with this requirement include:

  • Application Abandonment: If the oath or declaration is not submitted by the time the issue fee is paid, the application will be regarded as abandoned.
  • Additional Fees: To revive an abandoned application, the applicant must pay additional fees and file a petition for revival.
  • Delay in Patent Grant: The patent will not be granted until the proper oath or declaration is submitted and the application is revived.
  • Potential Loss of Patent Rights: In extreme cases, failure to timely submit the oath or declaration could result in a loss of patent rights if statutory deadlines are missed.

To avoid these issues, applicants should ensure that a proper inventor’s oath or declaration is submitted well before the issue fee payment deadline.

Failing to address drawing objections can have serious consequences for a patent application. According to MPEP 608.02(e), the primary consequence is the potential abandonment of the application. The MPEP states:

Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application.

Additionally, it’s important to note that drawing objections cannot be held in abeyance. The MPEP clarifies:

Unless applicant is otherwise notified in an Office action, objections to the drawings in a utility or plant application will not be held in abeyance, and a request to hold objections to the drawings in abeyance will not be considered a bona fide attempt to advance the application to final action.

This means that failing to address drawing objections can prevent the application from progressing, potentially leading to delays or even abandonment.

To learn more:

Failing to respond to an Office of Patent Application Processing (OPAP) notice regarding missing drawings can have serious consequences for a patent application. The outcomes differ depending on whether the application is nonprovisional or provisional:

For Nonprovisional Applications:

The MPEP clearly states: Failure to timely reply to the OPAP notice in a nonprovisional application will result in abandonment of the application.

This means:

  • The application will be considered abandoned
  • The applicant will lose their filing date
  • To continue pursuing patent protection, the applicant would need to file a new application or petition to revive the abandoned application

For Provisional Applications:

The consequences are less severe for provisional applications. The MPEP notes: For provisional applications in which applicant accepts the application as deposited by failing to timely file a petition in response to an OPAP notice regarding omitted items, if the provisional application is complete under 37 CFR 1.51(c), it will be held in the Office’s Image File Wrapper (IFW) system and automatically abandoned at the end of its pendency period.

This means:

  • The provisional application remains on file for its 12-month pendency period
  • It can still serve as a priority document for a later-filed nonprovisional application
  • However, the missing drawings will not be part of the application’s disclosure

It’s crucial for applicants to carefully review and respond to any OPAP notices to avoid potential loss of rights or limited disclosure in their patent applications.

To learn more:

The consequences of failing to respond to a 37 CFR 1.251 notice differ for pending applications and granted patents:

  • For pending applications: Failure to reply within the set time period will result in abandonment of the application. MPEP 508.04 cites 37 CFR 1.251(b): “With regard to a pending application, failure to comply with one of paragraphs (a)(1), (a)(2), or (a)(3) of this section within the time period set in the notice will result in abandonment of the application.”
  • For granted patents: While the patent won’t expire, there may be limitations on the certified copy of the patent file that the Office can produce. MPEP 508.04 states: “While abandonment (or expiration) of a patent is not an issue if a patentee fails to timely comply with a notice under 37 CFR 1.251, in such a situation the only certified copy of the patent file that the Office will be able to produce will be a copy of the patent and a copy of the application-as-filed (which may have an adverse impact during attempts to enforce the patent).”

Additionally, for patents involved in proceedings before the Office, action may be taken under 37 CFR 41.128 or 37 CFR 11.18.

According to MPEP 406, when the USPTO notifies an applicant of their patent practitioner’s death, the applicant is given a specific timeframe to respond. The MPEP states:

“The period for reply to such a notice is normally set at 3 months.”

During this 3-month period, the applicant must take one of the following actions:

  • Appoint a new registered patent practitioner
  • File a change of correspondence address

It’s crucial to respond within this timeframe to prevent the application from being deemed abandoned.

Filing a Continued Prosecution Application (CPA) has a significant effect on the prior application. According to the MPEP, A request for a CPA expressly abandons the prior application as of the filing date of the request for the CPA. This means that when you file a CPA, the previous application is automatically abandoned in favor of the new CPA. The CPA will use the file wrapper and contents of the prior application, including the specification, drawings, and oath or declaration, and will be assigned the same application number as the prior application.

To learn more:

The handling of provisional patent applications with missing drawings differs from nonprovisional applications. For provisional applications:

  • The USPTO does not grant petitions under 37 CFR 1.182 to accept omitted drawings and accord a later filing date
  • Applicants are advised to file a new, complete provisional application instead
  • Upon receiving an OPAP notice about missing drawings, applicants have two options:
    1. File a petition under 37 CFR 1.53(e) with evidence to establish prior receipt of the drawings
    2. Accept the application as deposited by not responding to the notice

The MPEP states: The USPTO will not grant petitions under 37 CFR 1.182 to accept omitted drawing(s) and accord an application filing date as of the date of such submission in provisional applications. The applicant should simply file a new completed provisional application.

If the applicant doesn’t respond to the OPAP notice and the provisional application is otherwise complete under 37 CFR 1.51(c), it will be held in the USPTO’s Image File Wrapper (IFW) system and automatically abandoned at the end of its pendency period.

To learn more:

Once a patent application is filed and given a filing date, it generally cannot be returned or withdrawn. According to MPEP 503:

“Applications which are entitled to a filing date, whether filed by regular mail, by Priority Mail Expressยฎ under 37 CFR 1.10, by hand-delivery, by the USPTO patent electronic filing system, or otherwise, will not be returned to applicant even if requested.”

This policy is in place to maintain the integrity of the filing process and prevent potential abuse. Applicants should be careful not to file applications that are not intended to be filed, such as duplicates of already filed applications.

Furthermore, the MPEP cites 37 CFR 1.26(a), which states that a change of purpose after payment of a fee, such as when a party desires to withdraw a patent application for which a fee was paid, does not entitle the party to a refund of such fee.

If an applicant realizes they have filed an application in error or no longer wish to pursue it, they may choose to abandon the application. However, the application will remain on file with the USPTO and any fees paid will not be refunded.

Patent Procedure (25)

For amended patent applications, it’s important to understand the expected timelines and when it’s appropriate to make a status inquiry:

  • Examiners are expected to act on amended applications within two months of receiving them.
  • A status inquiry is generally not necessary until 5-6 months have passed without a response from the USPTO.
  • If six months elapse without a response, you should inquire to avoid potential abandonment.

The MPEP advises: Amended applications are expected to be taken up by the examiner and an action completed within two months of the date the examiner receives the application. Accordingly, a status inquiry is not in order after reply by the attorney until 5 or 6 months have elapsed with no response from the Office. (MPEP 203.08)

It further states: However, in the event that a six month period has elapsed, and no response from the Office is received, applicant should inquire as to the status of the application to avoid potential abandonment.

For making inquiries, the MPEP recommends: Applicants are encouraged to use Patent Center or Private PAIR to make status inquiries.

To learn more:

The status of an application as ‘allowed’ has a specific timeframe. According to the MPEP:

“Its status as an ‘allowed’ application continues from the date of the notice of allowance until it issues as a patent, unless it is withdrawn from issue ( 37 CFR 1.313 ), or becomes abandoned for failure to pay the issue fee and any required publication fee ( 37 CFR 1.314 and 1.316 ).”

In other words, the ‘allowed’ status begins when the notice of allowance is sent and typically ends when the patent is issued. However, this status can be terminated if the application is withdrawn from issue or becomes abandoned due to non-payment of required fees.

To learn more:

What happens to the prior application when a CPA is filed?

When a Continued Prosecution Application (CPA) is filed, the prior application is automatically abandoned. According to MPEP 201.06(d):

The filing of a CPA is not a filing of a new application. Rather, a CPA is a continuation of the prior application and maintains the same application number as the prior application, i.e., a “streeting” of the prior application.

This means that:

  • The prior application is considered abandoned as of the filing date of the CPA.
  • The CPA is not assigned a new application number but continues under the number of the prior application.
  • All correspondence for the CPA should refer to the original application number.

It’s important to note that this automatic abandonment of the prior application is a key feature of CPA practice, distinguishing it from other types of continuing applications.

If the required translation or statement is missing for a non-English provisional application, the following consequences apply:

  1. The USPTO will issue a notice stating that the required documents are missing.
  2. The applicant must supply the missing translation and/or statement in the provisional application.
  3. The applicant must provide confirmation in the present application that the translation and statement were filed in the provisional application.
  4. If these requirements are not met within the time period set by the USPTO, the present application will be abandoned.

As stated in the MPEP, If 1) and 2) are not filed (or if the benefit claim is not withdrawn) prior to the expiration of the time period set in this Office action, the present application will be abandoned. See 37 CFR 1.78.

If the required translation and statement are not filed for a non-English provisional application, serious consequences can occur. According to MPEP ยถ 2.38:

“If 1) and 2) are not filed (or if the benefit claim is not withdrawn) prior to the expiration of the time period set in this Office action, the present application will be abandoned.”

This means that if you fail to provide the English translation and accuracy statement in the provisional application, and fail to confirm their filing in the present application, your current application may be abandoned. It’s crucial to comply with these requirements within the specified time frame to maintain your application’s active status.

What happens if the basic national fee is not paid on time for US national stage entry?

If the basic national fee is not paid on time for US national stage entry, the application will be considered abandoned. However, the MPEP provides guidance on potential remedies:

If the basic national fee is not paid on time, the Designated (or Elected) Office will declare that the application is considered withdrawn under PCT Article 24(1) or 39(2). However, if the basic national fee is paid later, accompanied by a petition for revival, the Designated (or Elected) Office may excuse the late payment of the basic national fee.

This means that while timely payment is crucial, there may be options to revive the application if the fee is paid late. Applicants should be aware that such petitions typically involve additional fees and are subject to specific requirements and time limits.

To learn more:

What happens if I file a provisional application and don’t file a nonprovisional within 12 months?

If you file a provisional application but do not file a corresponding nonprovisional application within 12 months, the provisional application will automatically be abandoned. As stated in the MPEP 201.04: “A provisional application will automatically be abandoned 12 months after its filing date and will not be subject to revival to restore it to pending status thereafter.” This means you lose the benefit of the provisional filing date and cannot claim priority to it in future applications. To maintain the priority benefit, you must file a nonprovisional application claiming benefit of the provisional within the 12-month period.

If you fail to provide the required English translation and statement of accuracy for a non-English provisional application, your current application may be abandoned. The MPEP states:

“If 1) and 2) are not filed (or if the benefit claim is not withdrawn) prior to the expiration of the time period set in this Office action, the present application will be abandoned. See 37 CFR 1.78.”

This means you must either provide the required documents or withdraw the benefit claim to avoid abandonment of your application.

If you don’t pay the issue fee for your patent application, it will be considered abandoned. According to MPEP 203.05, one of the ways an application can become abandoned is:

“for failure to pay the issue fee”

The MPEP refers to sections 711 to 711.05 for more details on this topic. It’s crucial to pay the issue fee on time to prevent your application from being abandoned after all the effort put into the patent prosecution process.

If drawings are not timely filed in response to a notice from the USPTO or a letter from the examiner requiring a drawing, the consequences are severe:

  • The application becomes abandoned for failure to reply.

The MPEP clearly states: If a drawing is not timely received in reply to a notice from the Office or a letter from the examiner who requires a drawing, the application becomes abandoned for failure to reply.

This underscores the importance of promptly responding to USPTO notices and examiner requirements regarding drawings. For information on handling replacement drawings, refer to MPEP ยง 608.02(h).

To learn more:

If an applicant fails to submit required application components within the specified time period, the following consequences may occur:

  • The application may be considered abandoned.
  • If abandoned, the application will be treated as though it had never been filed.
  • The applicant may lose the benefit of the original filing date.

The MPEP states: Upon failure to submit the fee, oath or declaration, and 1 or more claims within such prescribed period, the application shall be regarded as abandoned.

However, it may be possible to revive an abandoned application under certain circumstances:

  • The applicant can file a petition to revive under 37 CFR 1.137.
  • The petition must be accompanied by the required reply, the petition fee, and a statement that the entire delay was unintentional.

It’s crucial to respond to any notices from the USPTO promptly and to submit all required components within the specified timeframes to avoid these issues.

To learn more:

If a patent application is filed without a correspondence address:

  • The USPTO needs a correspondence address to notify the applicant of any missing parts or requirements.
  • If no address is provided, the Office may use the mailing address of the first named inventor as the correspondence address.
  • Without a correspondence address, the applicant is considered to have constructive notice of application requirements as of the filing date.
  • The applicant has 2 months from the filing date to complete the application before it is abandoned.

According to MPEP 403: “If a patent application as filed has been accorded a filing date but is not complete, the applicant is notified and given a period of time within which to file the missing parts to complete the application and pay the applicable surcharge. … If the applicant fails to provide the Office with a correspondence address, the Office will be unable to provide the applicant with notification to complete the application and to pay the surcharge as set forth in 37 CFR 1.16(f) for nonprovisional applications and 37 CFR 1.16(g) for provisional applications. In such a case, the applicant will be considered to have constructive notice as of the filing date that the application must be completed and the applicant will have 2 months from the filing date in which to do so before abandonment occurs.”

If a nonprovisional patent application is filed without all required fees, the USPTO will send a notice to the applicant. According to the MPEP:

Filing dates are accorded to nonprovisional applications filed under 37 CFR 1.53(b) submitted without the… required fees (basic filing fee, and search and examination fees (for applications filed on or after December 8, 2004))… In such cases, a notice is mailed by OPAP requiring the appropriate fees… accompanied by a surcharge (37 CFR 1.16(f)).

The applicant will be given a time period (usually two months) to pay the missing fees and surcharge to avoid abandonment of the application.

To maintain an allowed application’s status and proceed to patent issuance, certain fees must be paid. The MPEP mentions two specific fees:

  1. Issue fee: This is the fee required for the USPTO to issue the patent.
  2. Publication fee: If applicable, this fee covers the cost of publishing the patent application.

The MPEP states that an application becomes abandoned “for failure to pay the issue fee and any required publication fee ( 37 CFR 1.314 and 1.316 ).” Therefore, timely payment of these fees is crucial to maintain the allowed status and proceed to patent issuance.

To learn more:

An allowed application can lose its status under certain circumstances. The MPEP outlines two main scenarios:
