Patent Law FAQ

When the USPTO cannot locate a patent or application file after a reasonable search, they follow the procedure outlined in 37 CFR 1.251. The key steps are:

1. The Office notifies the applicant or patentee about the unlocatable file.
2. A time period is set for the applicant or patentee to comply with the notice.
3. The applicant or patentee must respond by either:
   • Providing a copy of their record of all correspondence with the Office (except U.S. patent documents)
   • Producing their record for the Office to copy
   • Stating that they do not possess any record of the correspondence

As stated in MPEP 508.04, “37 CFR 1.251 sets forth a procedure for the reconstruction of the file of a patent application, patent, or any other patent-related proceeding that cannot be located after a reasonable search.”

When a patent or application file cannot be located after a reasonable search, the USPTO has a specific procedure outlined in 37 CFR 1.251. The Office will notify the applicant or patentee and set a time period for compliance with one of the following options:

• Provide a copy of all correspondence records between the Office and the applicant/patentee, along with a list and a statement of completeness.
• Produce the applicant’s/patentee’s records for the Office to copy, along with a statement of completeness.
• If no records are possessed, provide a statement to that effect.

The MPEP states, 37 CFR 1.251 sets forth a procedure for the reconstruction of the file of a patent application, patent, or any other patent-related proceeding that cannot be located after a reasonable search.

For pending applications, failure to comply within the set time period will result in abandonment of the application.

According to MPEP 508.02, “After an application is patented or abandoned, any incoming communication which is not to become part of the record will be returned to the sender. If a paper has been scanned into the IFW, ‘return’ of the paper will be accomplished by the Office closing it in IFW.”

This means that any documents received after a patent is granted or an application is abandoned will not be added to the official record. Instead, they will be either physically returned to the sender or, if already scanned into the Image File Wrapper (IFW) system, electronically closed within the system.

After a patent is granted or an application is abandoned, the USPTO has specific procedures for handling incoming communications. According to the MPEP, After an application is patented or abandoned, any incoming communication which is not to become part of the record will be returned to the sender.

In the case of digital documents, the MPEP states, If a paper has been scanned into the IFW, ‘return’ of the paper will be accomplished by the Office closing it in IFW. This means that the document will be marked as closed in the digital system, effectively removing it from active consideration.

The time limits for responding to a notice under 37 CFR 1.251 vary depending on whether it’s for an application or a patent:

• For applications: The Office sets a three-month period for reply, which is extendable under 37 CFR 1.136(a) by up to three additional months, for a maximum of six months.
• For patents: The Office sets a six-month period for reply, which is not extendable.

MPEP 508.04 states: “The Office will set a time period of three months for reply in a notice under 37 CFR 1.251 in an application. The time period will be extendable under 37 CFR 1.136(a) (unless the notice indicates otherwise) by three months up to a maximum period for reply of six months in an application.” It also notes: “The Office will set a time period of six months for reply in a notice under 37 CFR 1.251 in a patent. The time period will not be extendable under 37 CFR 1.136(a) in a patent.”

The USPTO sets specific time limits for responding to notices about unlocatable files, which differ for applications and patents:

For applications, the MPEP states: The Office will set a time period of three months for reply in a notice under 37 CFR 1.251 in an application. The time period will be extendable under 37 CFR 1.136(a) (unless the notice indicates otherwise) by three months up to a maximum period for reply of six months in an application.

For patents, the time limit is longer: The Office will set a time period of six months for reply in a notice under 37 CFR 1.251 in a patent. The time period will not be extendable under 37 CFR 1.136(a) in a patent because 35 U.S.C. 41(a)(8) only authorizes the Office to charge fees for extensions of time in proceedings involving an application.

It’s important to note that failing to reply within these time limits can have serious consequences, including abandonment of pending applications.

When responding to a notice about an unlocatable file, applicants or patentees must provide copies of correspondence, but there are some exceptions. The MPEP states:

Any appendix or information disclosure statement submitted with an application is not contained in the Office’s database. Therefore, the applicant or patentee must also provide a copy of any appendix or information disclosure statement (except in the limited circumstance discussed below) submitted with the application.

However, there’s an important exception for U.S. patent documents:

Since the Office can obtain copies of U.S. patent documents (U.S. patent application publications and patents) from its internal databases, the Office is not requiring applicants or patentees to provide copies of U.S. patent application publications and patents that are among the applicant’s or patentee’s record of the correspondence between the Office and the applicant or patentee for the application, patent, or other proceeding.

This means that while most documents need to be resubmitted, U.S. patent documents can be omitted from the response.

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.

The USPTO has specific rules regarding patent term adjustments when dealing with notices about unlocatable files. According to the MPEP:

If, however, an applicant fails to reply to a notice under 37 CFR 1.251 within three months of its mailing date, any patent term adjustment under 35 U.S.C. 154(b) will be reduced by a period equal to the number of days (if any) beginning on the day after the date that is three months after the mailing date of the notice under 37 CFR 1.251 and ending on the date the reply to the notice under 37 CFR 1.251 was filed.

This reduction in patent term adjustment is based on 35 U.S.C. 154(b)(2)(C)(ii) and 37 CFR 1.704(b). It’s important to note that this reduction applies even if the applicant responds within the overall six-month period allowed for reply (including extensions).

This policy underscores the importance of prompt action in response to such notices, as delays can directly impact the duration of patent protection.

Patent applications are initially processed by the USPTO through electronic scanning and loading into the Image File Wrapper (IFW) system. According to MPEP 508, “All applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. Once documents are loaded into the IFW system, examiners, technical support staff, and other Office personnel will perform further processing and examination using the IFW system.”

Patent applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. As stated in the MPEP, All applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. This digital system allows examiners, technical support staff, and other Office personnel to perform further processing and examination efficiently.

For physical items such as models, exhibits, and specimens, special handling procedures are in place. The MPEP directs readers to MPEP § 608.03 and 608.03(a) for more information on these items.

The time period will not be extendable under 37 CFR 1.136(a) in a patent because 35 U.S.C. 41(a)(8) only authorizes the Office to charge fees for extensions of time in proceedings involving an application.

It’s important to note that failing to reply within these time limits can have serious consequences, including abandonment of pending applications.

When responding to a notice about an unlocatable file, applicants or patentees must provide copies of correspondence, but there are some exceptions. The MPEP states:

Any appendix or information disclosure statement submitted with an application is not contained in the Office’s database. Therefore, the applicant or patentee must also provide a copy of any appendix or information disclosure statement (except in the limited circumstance discussed below) submitted with the application.

However, there’s an important exception for U.S. patent documents:

Since the Office can obtain copies of U.S. patent documents (U.S. patent application publications and patents) from its internal databases, the Office is not requiring applicants or patentees to provide copies of U.S. patent application publications and patents that are among the applicant’s or patentee’s record of the correspondence between the Office and the applicant or patentee for the application, patent, or other proceeding.

This means that while most documents need to be resubmitted, U.S. patent documents can be omitted from the response.

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.

The USPTO has specific rules regarding patent term adjustments when dealing with notices about unlocatable files. According to the MPEP:

If, however, an applicant fails to reply to a notice under 37 CFR 1.251 within three months of its mailing date, any patent term adjustment under 35 U.S.C. 154(b) will be reduced by a period equal to the number of days (if any) beginning on the day after the date that is three months after the mailing date of the notice under 37 CFR 1.251 and ending on the date the reply to the notice under 37 CFR 1.251 was filed.

This reduction in patent term adjustment is based on 35 U.S.C. 154(b)(2)(C)(ii) and 37 CFR 1.704(b). It’s important to note that this reduction applies even if the applicant responds within the overall six-month period allowed for reply (including extensions).

This policy underscores the importance of prompt action in response to such notices, as delays can directly impact the duration of patent protection.

Patent applications are initially processed by the USPTO through electronic scanning and loading into the Image File Wrapper (IFW) system. According to MPEP 508, “All applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. Once documents are loaded into the IFW system, examiners, technical support staff, and other Office personnel will perform further processing and examination using the IFW system.”

Patent applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. As stated in the MPEP, All applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. This digital system allows examiners, technical support staff, and other Office personnel to perform further processing and examination efficiently.

For physical items such as models, exhibits, and specimens, special handling procedures are in place. The MPEP directs readers to MPEP § 608.03 and 608.03(a) for more information on these items.
