USPTO Registration Practice Exam

The revocation of Power of Attorney in the context of the USPTO is indeed effective upon being received at the Patent Office. This means that once the notification of the revocation is properly submitted to and received by the Patent Office, it takes effect immediately. This is important because it ensures that the change in representation is recognized promptly, which can be crucial in the context of patent proceedings or ongoing applications.

The mechanism for revocation does not require a court order, nor does it necessitate notarization for it to be valid, though there are certain formalities that should be followed, such as submitting the revocation in writing to the Patent Office. The administrative guidelines do provide procedures that must be adhered to when submitting such documents, but the key takeaway is that the revocation itself is instantaneous once it is received, making it a straightforward process in terms of changing representation.
