MPEP 105 - Suspended or Excluded Practitioner Cannot Inspect (1)

No, a patent attorney or agent who has been suspended or excluded from practice by the USPTO cannot inspect patent applications, unless they are an inventor or applicant on that particular application. The MPEP states:

USPTO employees are forbidden to hold either oral or written communication with an attorney or agent who has been suspended or excluded from practice by the USPTO regarding an application unless it is one in which said attorney or agent is an inventor or the applicant. Power to inspect given to such an attorney or agent will not be accepted.

This policy prevents suspended or excluded practitioners from accessing confidential application information they are no longer authorized to view.

MPEP 200 - Types and Status of Application; Benefit and Priority Claims (1)

Yes, the foreign application may have been filed by and in the name of the assignee or legal representative or agent of the inventor, as applicant.

If the certified copy of the foreign application corresponds with the one identified in the U.S. application and no discrepancies appear, it may be assumed the U.S. application is entitled to claim priority to the foreign application.

If the U.S. application and the certified copy do not name the same inventor or have at least one joint inventor in common, the priority date should be refused until the inconsistency is resolved. [MPEP 216]

MPEP 216 - Entitlement to Priority (1)

Yes, the foreign application may have been filed by and in the name of the assignee or legal representative or agent of the inventor, as applicant.

If the certified copy of the foreign application corresponds with the one identified in the U.S. application and no discrepancies appear, it may be assumed the U.S. application is entitled to claim priority to the foreign application.

If the U.S. application and the certified copy do not name the same inventor or have at least one joint inventor in common, the priority date should be refused until the inconsistency is resolved. [MPEP 216]

MPEP 400 - Representative of Applicant or Owner (5)

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 §§ 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.”

How does the USPTO handle correspondence for applications with multiple attorneys or agents?

When an application has multiple attorneys or agents of record, the USPTO follows specific guidelines for correspondence:

  • The USPTO will direct all correspondence to the first named attorney or agent of record, unless otherwise specified.
  • If a customer number is provided, correspondence will be sent to the address associated with that customer number.
  • Applicants can designate one or more attorneys or agents to receive correspondence by filing a power of attorney or including the information in an application data sheet.

As stated in the MPEP:

If applicant provides, in a single paper, a list of patent practitioners and a correspondence address without also filing a clear power of attorney to a patent practitioner, the Office will direct all correspondence to the correspondence address pursuant to 37 CFR 1.33(a). (MPEP 403)

It’s important to clearly designate correspondence preferences to ensure proper communication with the USPTO.
