MPEP 400 - Representative of Applicant or Owner (14)

A Customer Number is a unique identifier assigned by the USPTO that can be associated with a correspondence address. It offers several advantages in managing patent application correspondence:

  • Simplified address changes: You can update the address for multiple applications at once by changing the address associated with the Customer Number.
  • Priority in address selection: When multiple addresses are provided, the USPTO may prioritize the address associated with a Customer Number.
  • Easier access to Patent Application Information Retrieval (PAIR) system: Customer Numbers can be used to access multiple applications in PAIR.

37 CFR 1.33(a) states: If more than one correspondence address is specified, the Office will select one of the specified addresses for use as the correspondence address and, if given, may select the address associated with a Customer Number over a typed correspondence address.

Using a Customer Number can streamline communication with the USPTO and make it easier to manage multiple patent applications.

To learn more:

The correspondence address in a patent application is the address where the United States Patent and Trademark Office (USPTO) will send all official communications regarding the application. According to 37 CFR 1.33(a):

“When filing an application, a correspondence address must be set forth in either an application data sheet (ยง 1.76), or elsewhere, in a clearly identifiable manner, in any paper submitted with an application filing.”

This address is crucial for ensuring that applicants receive all necessary information and notifications about their patent application.

To learn more:

When one of multiple practitioners of record is suspended, the USPTO continues to communicate with the remaining unsuspended practitioners. MPEP ยง 407 provides guidance for this situation: “This form paragraph should be used when there is at least one registered practitioner still of record who has not been suspended or excluded from practice.” The Office action is mailed to the first named unsuspended registered practitioner at their address of record. Additionally, to ensure timely receipt, a copy is also sent to the first named applicant’s address of record.

What happens if an attorney or agent withdraws from representation in a patent application?

When an attorney or agent withdraws from representation in a patent application, the following occurs:

  • The USPTO will correspond directly with the applicant until a new Power of Attorney or address change is filed.
  • The withdrawal is effective when approved by the Office, not when received.
  • The Office may require the applicant or assignee to revoke the previous Power of Attorney and appoint a new representative.

As stated in MPEP 402.06: ‘In the event the power of attorney is withdrawn, the Office will communicate directly with the applicant… until a new registered attorney or agent is appointed.’

To learn more:

To learn more:

The USPTO generally does not engage in double correspondence with applicants and their representatives. Specifically:

  • The Office will not correspond with both an applicant and their attorney/agent.
  • The Office will not correspond with more than one attorney/agent.
  • If double correspondence is attempted, the examiner will include form paragraph 4.01 in the next Office action.

According to MPEP 403: “Double correspondence with an applicant and their attorney, or with two representatives, will not be undertaken. See MPEP ยงยง 403.01(a), 403.01(b), 403.02, and 714.01(d).”

Form paragraph 4.01 states: “Applicant has appointed an attorney or agent to conduct all business before the Patent and Trademark Office. Double correspondence with an applicant and applicant’s attorney or agent will not be undertaken. Accordingly, applicant is required to conduct all future correspondence with this Office through the attorney or agent of record. See 37 CFR 1.33.”

When two patent practitioners are appointed, the handling of correspondence depends on how and when they were appointed. According to MPEP 403.02:

“If, after one patent practitioner is appointed, a second patent practitioner is later added by submission of a new power of attorney appointing both practitioners, correspondence will be mailed to the latest correspondence address of record.”

This means that the USPTO will use the most recently provided correspondence address. It’s important to note that this is governed by 37 CFR 1.33 and 37 CFR 1.76, which provide regulations on correspondence and application data sheets.

To learn more:

When a practitioner withdraws and the correspondence address will change as a result, the withdrawing practitioner(s) must request that the USPTO direct all future correspondence to one of the following:

  • The first named inventor or assignee that has properly made itself of record (for applications filed before September 16, 2012)
  • The applicant (for applications filed on or after September 16, 2012)
  • The assignee of record (for proceedings involving issued patents)

Practitioners can specify either the correspondence address or the address associated with the Customer Number of the appropriate party. It’s important to note that withdrawing practitioners cannot change the correspondence address to another law firm’s Customer Number or any other address except those mentioned above.

This ensures that the patent application or proceeding remains properly managed after the practitioner’s withdrawal.

To learn more:

After an attorney withdraws from a patent application, the USPTO adjusts its communication process as follows:

  • The Office communicates directly with the applicant or assignee.
  • This direct communication continues until a new registered patent practitioner is appointed.
  • The applicant or assignee who originally appointed the withdrawing attorney becomes the point of contact for all purposes in the application.

According to MPEP 402.06: ‘For applications in which the attorney or agent has withdrawn from representation, the Office will communicate directly with the applicant … until such time as a new attorney or agent is appointed.’

It’s crucial for applicants to stay responsive and consider appointing new representation promptly to ensure smooth prosecution of their patent application.

To learn more:

The USPTO determines the correspondence address based on the most recent information provided. According to MPEP 403.02:

“If, after one patent practitioner is appointed, a second patent practitioner is later added by submission of a new power of attorney appointing both practitioners, correspondence will be mailed to the latest correspondence address of record.”

This means that the USPTO will use the most recently provided correspondence address, regardless of which practitioner it is associated with. This practice is governed by 37 CFR 1.33 and 37 CFR 1.76, which provide regulations on correspondence and application data sheets. It’s crucial for applicants and practitioners to keep the correspondence address up to date to ensure proper communication with the USPTO.

To learn more:

When an attorney or agent is suspended, the USPTO does not communicate with them. Instead:

  • For sole practitioners: The Office action is mailed to the address of the first named applicant in the application.
  • For multiple practitioners: The Office action is mailed to the first named unsuspended registered practitioner of record and to the first named applicant.

This is outlined in Form Paragraphs 4.07 and 4.08 of MPEP ยง 407.

When a power of attorney is revoked, it affects pending applications as follows:

  • The revocation is effective upon receipt in the USPTO.
  • It applies to all pending applications in which the attorney or agent was appointed, unless specifically limited.
  • The Office will not communicate further with the revoked attorney/agent.
  • The applicant must appoint a new representative or correspond directly with the Office.

As stated in MPEP 402.05: ‘A power of attorney may be revoked at any stage in the proceedings of a case.’ This means the revocation can occur at any point during the patent application process.

To learn more:

How does attorney withdrawal affect pending patent applications?

When an attorney withdraws from representation in a pending patent application, it can have several implications:

  • The applicant becomes responsible for prosecuting the application.
  • Official correspondence will be sent directly to the applicant.
  • Deadlines and response periods remain in effect.
  • The applicant may need to find new representation quickly.

According to MPEP 402.06:

“Where an attorney or agent of record withdraws from an application, the Office will communicate directly with the applicant, or with a new registered attorney or agent if a power of attorney is filed.”

It’s important for applicants to act promptly after attorney withdrawal to ensure continuity in their patent prosecution. If a new attorney is hired, a new power of attorney should be filed with the USPTO to ensure proper communication and representation.

To learn more:

Can an applicant communicate directly with the USPTO if they have a registered patent attorney?

Generally, when an applicant is represented by a registered patent attorney or agent, direct communication between the applicant and the USPTO is discouraged. The USPTO has specific rules regarding this situation:

  • The USPTO will communicate directly with the registered attorney or agent of record.
  • Applicants should channel their communications through their appointed representative.
  • Direct communication from the applicant may not be officially recognized or acted upon by the USPTO.

MPEP 403.01 clearly states: “The Office will not engage in double correspondence with an applicant and a patent practitioner, or with more than one patent practitioner except as deemed necessary by the Director.” This policy ensures clear and efficient communication channels and prevents potential confusion or contradictory instructions. If an applicant wishes to communicate directly, they should first revoke the power of attorney or authorization of agent on record.

To learn more:

Yes, an applicant can appoint two patent practitioners for the same application. However, when doing so, it’s important to specify the correspondence address. As stated in the MPEP:

“If the applicant simultaneously appoints two patent practitioners, applicant should indicate with whom correspondence is to be conducted by specifying a correspondence address.”

This ensures clear communication between the USPTO and the applicant’s representatives. For more details, refer to MPEP ยง 403, MPEP ยง 403.01(a), and MPEP ยง 403.01(b).

“If, after one patent practitioner is appointed, a second patent practitioner is later added by submission of a new power of attorney appointing both practitioners, correspondence will be mailed to the latest correspondence address of record.”

This means that the USPTO will use the most recently provided correspondence address, regardless of which practitioner it is associated with. This practice is governed by 37 CFR 1.33 and 37 CFR 1.76, which provide regulations on correspondence and application data sheets. It’s crucial for applicants and practitioners to keep the correspondence address up to date to ensure proper communication with the USPTO.

To learn more:

When an attorney or agent is suspended, the USPTO does not communicate with them. Instead:

  • For sole practitioners: The Office action is mailed to the address of the first named applicant in the application.
  • For multiple practitioners: The Office action is mailed to the first named unsuspended registered practitioner of record and to the first named applicant.

This is outlined in Form Paragraphs 4.07 and 4.08 of MPEP ยง 407.

When a power of attorney is revoked, it affects pending applications as follows:

  • The revocation is effective upon receipt in the USPTO.
  • It applies to all pending applications in which the attorney or agent was appointed, unless specifically limited.
  • The Office will not communicate further with the revoked attorney/agent.
  • The applicant must appoint a new representative or correspond directly with the Office.

As stated in MPEP 402.05: ‘A power of attorney may be revoked at any stage in the proceedings of a case.’ This means the revocation can occur at any point during the patent application process.

To learn more:

A Customer Number is a unique identifier assigned by the USPTO that can be associated with a correspondence address. It offers several advantages in managing patent application correspondence:

  • Simplified address changes: You can update the address for multiple applications at once by changing the address associated with the Customer Number.
  • Priority in address selection: When multiple addresses are provided, the USPTO may prioritize the address associated with a Customer Number.
  • Easier access to Patent Application Information Retrieval (PAIR) system: Customer Numbers can be used to access multiple applications in PAIR.

37 CFR 1.33(a) states: If more than one correspondence address is specified, the Office will select one of the specified addresses for use as the correspondence address and, if given, may select the address associated with a Customer Number over a typed correspondence address.

Using a Customer Number can streamline communication with the USPTO and make it easier to manage multiple patent applications.

To learn more:

The receipt date for facsimile transmissions to the USPTO is determined according to specific rules outlined in MPEP 502.01:

The date of receipt accorded to any correspondence permitted to be sent by facsimile transmission, including a continued prosecution application (CPA) filed under 37 CFR 1.53(d), (available for design applications only) is the date the complete transmission is received by an Office facsimile unit, unless the transmission is completed on a Saturday, Sunday, or Federal holiday within the District of Columbia.

If the transmission is completed on a weekend or federal holiday in DC, the receipt date will be the next business day. For example, if a fax is completed at 9:05 p.m. Pacific time on a Friday, it would be received around 12:05 a.m. Eastern time on Saturday. The receipt date would then be the following Monday (assuming it’s not a federal holiday).

It’s important to note that the Certificate of Transmission under 37 CFR 1.8 can be used for certain documents to consider them timely filed on the date of transmission, even if received later by the USPTO.

  • This direct communication continues until a new registered patent practitioner is appointed.
  • The applicant or assignee who originally appointed the withdrawing attorney becomes the point of contact for all purposes in the application.

According to MPEP 402.06: ‘For applications in which the attorney or agent has withdrawn from representation, the Office will communicate directly with the applicant … until such time as a new attorney or agent is appointed.’

It’s crucial for applicants to stay responsive and consider appointing new representation promptly to ensure smooth prosecution of their patent application.

The USPTO determines the correspondence address based on the most recent information provided. According to MPEP 403.02:

“If, after one patent practitioner is appointed, a second patent practitioner is later added by submission of a new power of attorney appointing both practitioners, correspondence will be mailed to the latest correspondence address of record.”

This means that the USPTO will use the most recently provided correspondence address, regardless of which practitioner it is associated with. This practice is governed by 37 CFR 1.33 and 37 CFR 1.76, which provide regulations on correspondence and application data sheets. It’s crucial for applicants and practitioners to keep the correspondence address up to date to ensure proper communication with the USPTO.

When an attorney or agent is suspended, the USPTO does not communicate with them. Instead:

  • For sole practitioners: The Office action is mailed to the address of the first named applicant in the application.
  • For multiple practitioners: The Office action is mailed to the first named unsuspended registered practitioner of record and to the first named applicant.

This is outlined in Form Paragraphs 4.07 and 4.08 of MPEP ยง 407.

When a power of attorney is revoked, it affects pending applications as follows:

  • The revocation is effective upon receipt in the USPTO.
  • It applies to all pending applications in which the attorney or agent was appointed, unless specifically limited.
  • The Office will not communicate further with the revoked attorney/agent.
  • The applicant must appoint a new representative or correspond directly with the Office.

As stated in MPEP 402.05: ‘A power of attorney may be revoked at any stage in the proceedings of a case.’ This means the revocation can occur at any point during the patent application process.

How does attorney withdrawal affect pending patent applications?

When an attorney withdraws from representation in a pending patent application, it can have several implications:

  • The applicant becomes responsible for prosecuting the application.
  • Official correspondence will be sent directly to the applicant.
  • Deadlines and response periods remain in effect.
  • The applicant may need to find new representation quickly.

According to MPEP 402.06:

“Where an attorney or agent of record withdraws from an application, the Office will communicate directly with the applicant, or with a new registered attorney or agent if a power of attorney is filed.”

It’s important for applicants to act promptly after attorney withdrawal to ensure continuity in their patent prosecution. If a new attorney is hired, a new power of attorney should be filed with the USPTO to ensure proper communication and representation.

To authorize email communications with the USPTO, an applicant must provide a written authorization. According to MPEP 502.03:

‘The written authorization may be submitted via EFS-Web, mail, or fax. It cannot be submitted by email.’

The USPTO provides a sample authorization form:

‘Recognizing that Internet communications are not secure, I hereby authorize the USPTO to communicate with the undersigned and practitioners in accordance with 37 CFR 1.33 and 37 CFR 1.34 concerning any subject matter of this application by video conferencing, instant messaging, or electronic mail. I understand that a copy of these communications will be made of record in the application file.’

To facilitate processing, the USPTO recommends using Form PTO/SB/439, available at www.uspto.gov/patent/patents-forms. This form can be filed via EFS-Web using the document description ‘Internet Communications Authorized’.

Yes, an applicant can withdraw their authorization for email communication with the USPTO. According to MPEP 502.03:

‘A written authorization may be withdrawn by filing a signed paper clearly identifying the original authorization.’

The USPTO provides a sample form for withdrawing authorization:

‘The authorization given on______, to the USPTO to communicate with any practitioner of record or acting in a representative capacity in accordance with 37 CFR 1.33 and 37 CFR 1.34 concerning any subject matter of this application via video conferencing, instant messaging, or electronic mail is hereby withdrawn.’

To facilitate processing, the USPTO recommends using Form PTO/SB/439, available at www.uspto.gov/patent/patents-forms. This form can be filed via EFS-Web using the document description ‘Internet Communications Authorization Withdrawn’.

Can an applicant communicate directly with the USPTO if they have a registered patent attorney?

Generally, when an applicant is represented by a registered patent attorney or agent, direct communication between the applicant and the USPTO is discouraged. The USPTO has specific rules regarding this situation:

  • The USPTO will communicate directly with the registered attorney or agent of record.
  • Applicants should channel their communications through their appointed representative.
  • Direct communication from the applicant may not be officially recognized or acted upon by the USPTO.

MPEP 403.01 clearly states: “The Office will not engage in double correspondence with an applicant and a patent practitioner, or with more than one patent practitioner except as deemed necessary by the Director.” This policy ensures clear and efficient communication channels and prevents potential confusion or contradictory instructions. If an applicant wishes to communicate directly, they should first revoke the power of attorney or authorization of agent on record.

To learn more:

Yes, an applicant can appoint two patent practitioners for the same application. However, when doing so, it’s important to specify the correspondence address. As stated in the MPEP:

“If the applicant simultaneously appoints two patent practitioners, applicant should indicate with whom correspondence is to be conducted by specifying a correspondence address.”

This ensures clear communication between the USPTO and the applicant’s representatives. For more details, refer to MPEP ยง 403, MPEP ยง 403.01(a), and MPEP ยง 403.01(b).
