How are changes to applicant information handled in international patent applications?

Changes to applicant information in international patent applications are handled according to specific rules:

• Requests for changes in indications concerning the applicant, agent, or common representative must be made in accordance with PCT Rule 92bis.
• Such requests may require signatures from all applicants.
• Withdrawals of the application, designations, priority claims, demands, or elections must be made according to PCT Rule 90bis and must be signed by all applicants.
• A separate power of attorney may be required for withdrawals not signed by all applicants.

The MPEP states: Requests for changes in the indications concerning the applicant, agent, or common representative of an international application shall be made in accordance with PCT Rule 92bis and may be required to be signed by all applicants.

It’s important to follow these procedures carefully to ensure that changes are properly recorded and recognized in the international application process.
