Opposition, Cancellation, and Other Post-Registration Remedies
Opposition and cancellation are inter partes checks on registration. They are heard by IPOPHL's Bureau of Legal Affairs, not the examiner, and they reward precise pleading and evidence.
Core rules
- Any person who believes he would be damaged may oppose within 30 days from publication, stating grounds and furnishing proof of standing and fees.
- Opposition grounds include prior rights, confusing similarity, well-known mark status, bad faith, and absolute grounds.
- Cancellation may be sought for non-use, abandonment, genericness, fraud, or a prior right that was not considered.
- Non-use for an uninterrupted five-year period is a classic cancellation ground; the registrant must show genuine commercial use in the Philippines.
- The registered owner may counterclaim or seek cancellation of the opponent's mark in appropriate cases.
- Decisions of the Bureau of Legal Affairs are appealed to the Director General, then to the Court of Appeals.
Worked example
A registrant owns 'LAGUNA BUKO' for bottled coconut juice. A competitor petitions to cancel, alleging the registrant stopped selling for six years and that 'LAGUNA BUKO' is descriptive. The registrant produces old brochures but no invoices, labels, or sales records for the relevant period. The Bureau finds non-use and cancels. The descriptiveness argument is secondary, but the lack of genuine use is decisive.
Traps
A petition is not a chance to relitigate examination without evidence. Plead the specific ground and attach proof. Do not assume a registration is immune after five years; fraud and non-use can still be raised. Missing the 30-day opposition period usually bars opposition, though cancellation may remain available. Appeals have their own deadlines.
