How can an assignee revoke a power of attorney in applications filed on or after September 16, 2012?

For applications filed on or after September 16, 2012, an assignee must first become the applicant under 37 CFR 1.46(c) to revoke a previously given power of attorney and/or grant a new one. This is because, as stated in the MPEP, any power of attorney must be signed by the applicant or patent owner. The process involves:

• The assignee becoming the applicant
• Revoking the previous power of attorney
• Granting a new power of attorney

For more details on establishing the right of an assignee to take action, refer to MPEP § 325.
