Sao Tome and Principe Trademark Renewal

Trademarks are valid for 10 years from the registration date and can be renewed indefinitely in successive 10-year terms.

• Renewal window: During the last 6 months of the trademark validity
• Grace period: 6 months after expiration
• After grace period: A revalidation request may be filed within 1 year from publication of lapse, subject to tripled fees

• No special documents required
• Payment of the renewal fee
• Renewal is published in the Intellectual Property Bulletin, and a renewal certificate is issued

• A lapsed trademark may be revalidated within 1 year from the lapse publication by:
• Paying three times the standard renewal fee
• Filing a request without prejudice to third-party rights
• Re-registration by third parties is generally not permitted during the revalidation period

• The registry does not issue renewal reminders
• Trademark holders must independently track deadlines

Avoid:

• Forgetting to renew during the 6-month grace period
• Delaying revalidation beyond 1 year of lapse publication
• Underestimating the tripled fee for revalidation

You may still renew within 6 months post-expiration with a late fee. After that, revalidation is possible within 1 year, subject to triple fees.
