Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
When a new power of attorney is filed, it generally revokes all prior powers of attorney. MPEP 402.05(a) provides several scenarios:
- If a new power of attorney is filed without explicitly revoking prior ones, it will be treated as a revocation of the original power of attorney.
- If an assignee files a new power of attorney, it revokes and replaces the original power of attorney filed by the applicant.
- If a power of attorney is given to practitioners associated with a Customer Number, and a second power of attorney is later received for a different Customer Number, the second one will replace the first.
The MPEP states:
In all of these situations, the most recently filed power of attorney will control.
This means that the latest power of attorney filed will take precedence over any previously filed ones.
