MPEP 300 - Ownership and Assignment (7)

The USPTO does not process requests for indexing or cross-referencing additional patent numbers or application numbers against a document previously recorded in the Assignment Division, unless it’s an assignment. This policy is based on compliance with 37 CFR 3.11, 3.28, and 3.31.

As stated in MPEP 315: “The Office does not process requests for ‘indexing’ or ‘cross-referencing’ additional patent numbers or application numbers against a document, other than an assignment, previously recorded in the Assignment Division.”

The USPTO treats conditional assignments as absolute assignments for Office purposes. According to 37 CFR 3.56:

“Assignments which are made conditional on the performance of certain acts or events, such as the payment of money or other condition subsequent, if recorded in the Office, are regarded as absolute assignments for Office purposes until canceled with the written consent of all parties or by the decree of a court of competent jurisdiction.”

The USPTO does not determine whether conditions have been fulfilled. Recording a conditional assignment is treated as signifying that the condition has been met.

To learn more:

No, the USPTO does not determine whether conditions in a conditional assignment have been fulfilled. According to 37 CFR 3.56:

“The Office does not determine whether such conditions have been fulfilled.”

The USPTO treats the submission of a conditional assignment for recordation as an indication that the condition has been met. This policy simplifies the Office’s handling of assignments and places the responsibility on the parties involved to ensure conditions are met before recording.

To learn more:

No, recorded assignment documents will not be expunged even if they are subsequently found to be invalid. The USPTO’s policy is to maintain a complete history of claimed interests in property.

As stated in the MPEP: “Office policy regarding recordation of assignment documents is directed toward maintaining a complete history of claimed interests in property and, therefore, recorded assignment documents will not be expunged even if subsequently found to be invalid. See In re Ratny, 24 USPQ2d 1713 (Comm’r Pat. 1992).” (MPEP ยง 323)

Once a document is recorded with the Assignment Services Division, it will not be removed from the record relating to that application or patent.

The USPTO does not grant partial access to assignment documents. According to MPEP 301.01:

The Office will not open only certain parts of an assignment document to public inspection. If such a document contains two or more items, any one of which, if alone, would be open to such inspection, then the entire document will be open.

This policy ensures transparency and prevents selective disclosure of information. It’s important to note that this approach can have implications for documents that contain both public and potentially confidential information. For example:

  • If a document covers both a trademark and a patent application, the entire document becomes public.
  • If a document covers multiple patent applications, it becomes public as soon as any one of the applications is published or patented.

This policy underscores the importance of carefully considering what information is included in assignment documents, particularly when dealing with a mix of public and non-public intellectual property rights.

No, you should not submit original documents for recording patent assignments. The USPTO explicitly states:

“The United States Patent and Trademark Office will accept and record only a copy of an original assignment or other document. See MPEP ยง 317. The document submitted for recordation will not be returned to the submitter.”

It’s crucial to submit only copies of original documents, as the USPTO will not return the recorded documents. This ensures that you retain your original documents while still complying with the recording requirements.

No, the USPTO does not allow partial access to patent assignment documents. According to MPEP 301.01:

“The Office will not open only certain parts of an assignment document to public inspection. If such a document contains two or more items, any one of which, if alone, would be open to such inspection, then the entire document will be open.”

This means:

  • If a document covers both a trademark and a patent, it will be entirely available to the public from the beginning.
  • If it covers multiple patent applications, it becomes publicly available as soon as any one of them is published or patented.

The policy ensures transparency and consistency in the handling of assignment documents.

MPEP 400 - Representative of Applicant or Owner (2)

No, a power of attorney cannot be partially revoked for specific patent applications. The MPEP 402.05 states:

‘A principal cannot revoke selected powers of the power of attorney while leaving other powers in effect.’

This means that when revoking a power of attorney, it must be revoked in its entirety for all applications and patents to which it was applied. If you wish to maintain representation for certain applications while revoking others, you would need to file a new power of attorney for those specific applications you want to keep under representation.

To learn more:

No, a patent practitioner cannot appoint a substitute to take over their cases after death. The MPEP 406 clearly states: “The patent practitioner may not appoint a ‘substitute’ and any attempt by the patent practitioner to appoint a ‘substitute’ patent practitioner whose power is intended to survive his or her own will not be recognized by the Office.” This means that any arrangements made by a practitioner for a substitute after their death will not be valid in the eyes of the USPTO.
