Patent Law FAQ

When revoking a power of attorney in a situation where there is no practitioner of record, special considerations apply. The MPEP 402.05 states:

‘If a power of attorney is revoked, and a new power of attorney is not promptly filed, then pursuant to 37 CFR 1.33(a) the correspondence address will be changed to that of the inventor(s) or assignee(s) who last provided a correspondence address.’

This means:

• The USPTO will change the correspondence address to that of the inventor(s) or assignee(s).
• The last provided correspondence address by the inventor(s) or assignee(s) will be used.
• All future communications from the USPTO will be sent to this address.
• It’s crucial to provide a new power of attorney or update the correspondence address promptly to ensure receipt of important communications.
