Thailand Trademark Renewal

A trademark is valid for 10 years from the date of registration and may be renewed for additional 10-year periods indefinitely.

• Renewal window: Begins 3 months before the expiration date
• Grace period: 6 months after expiration
• After grace period: The trademark is removed from the register, and re-registration is required

• Notarized Power of Attorney, signed by an authorized person of the applicant
• Filing the renewal application form
• No evidence of use is required
• Renewals are not published

• Restoration is not permitted
• A lapsed trademark must be re-registered
• Third parties can re-register a lapsed trademark, though infringement risks exist if done in bad faith

• DIP does not notify trademark owners or agents about upcoming expirations
• Monitoring is the responsibility of the owner or their legal representative

Avoid:

• Failing to notarize the Power of Attorney
• Missing the 6-month grace period
• Assuming the DIP will send reminders

You can renew within 6 months of expiry with a 20% surcharge. After that, the trademark is removed and you must file a new application.

No. Restoration is not allowed in Thailand. A new registration must be filed.

No. Use is not required to renew a trademark in Thailand.

Notify the Department of Intellectual Property (DIP) with updated documents and a notarized Power of Attorney.
