317.03    Effect of Recording [R-11.2013]

37 C.F.R. 3.54 Effect of recording.

The recording of a document pursuant to § 3.11 is not a determination by the Office of the validity of the document or the effect that document has on the title to an application, a patent, or a registration. When necessary, the Office will determine what effect a document has, including whether a party has the authority to take an action in a matter pending before the Office.

37 C.F.R. 3.56 Conditional assignments.

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 Office does not determine whether such conditions have been fulfilled.

The recording of a document is not a determination by the Office of the validity of the document or the effect that document has on the title to an application or patent. When necessary, the Office will determine what effect a document has, including whether a party has the authority to take an action in a matter pending before the Office. See MPEP §§ 324 and325.

37 CFR 3.56 provides that an assignment, which at the time of its execution is conditional on a given act or event, will be treated by the Office as an absolute assignment. This rule serves as notification as to how a conditional assignment will be treated by the Office in any proceeding requiring a determination of the owner of an application, patent, or registration. Since the Office will not determine whether a condition has been fulfilled, the Office will treat the submission of such an assignment for recordation as signifying that the act or event has occurred. A security agreement that does not convey the right, title, and interest of a patent property is not a conditional assignment.
