What are the requirements for signing a withdrawal of demand or election in a PCT application?
MPEP 1880 outlines specific requirements for signing a withdrawal of demand or election in a PCT application:
Any withdrawal of the demand or any election must be sent to the International Bureau or to the International Preliminary Examining Authority, provided that the withdrawal is signed by all applicants in accordance with PCT Rule 90bis.5.
Furthermore, the MPEP states:
Pursuant to PCT Rules 90.4(e) and 90.5(d), the requirement for a separate power of attorney or a copy of the general power of attorney shall not be waived in cases of withdrawal.
This means that all applicants must sign the withdrawal, and if an agent is acting on behalf of the applicants, a power of attorney is required and cannot be waived for withdrawal actions.
