When to think about opposition
Opposition is the formal way to object to someone else's trademark application before it is registered. If a published application is identical or confusingly similar to your mark, covers related goods, or was filed in bad faith, opposing it is usually far cheaper and faster than trying to cancel a registration later.
The opportunity is time-limited. Applications are published for a set period during which objections can be filed, and missing that window narrows your options. That is why many owners pair a registration with a watch service that alerts them to new filings.
Grounds for an opposition
- Earlier rights: you own an earlier registration or application for a similar mark covering related goods or services.
- Well-known marks: your mark is well known and the new filing would take unfair advantage of it, even in unrelated classes.
- Bad faith: the applicant knew of your brand, for example as a former distributor or agent, and filed to block or exploit it.
- Absolute grounds: the applied-for mark is descriptive, misleading or otherwise not registrable.
How an opposition runs
- Spot the applicationThrough a watch service, a search, or a tip from a partner in the market.
- Assess the caseWe compare the marks and goods, review your evidence of use and reputation, and advise whether to oppose.
- File the notice and argumentsThe opposition sets out the grounds and supporting evidence within the deadline.
- Exchange and decisionThe applicant may respond, and a decision follows. Many disputes settle along the way through coexistence or withdrawal.
If the mark is already registered
Missing the opposition window is not the end. A registered mark can sometimes be challenged through cancellation or invalidation, for example where it was registered in bad faith, conflicts with an earlier right, or has not been used. These routes usually take longer and need stronger evidence, so acting early remains the better choice.
Evidence that helps
Gather proof of your earlier rights and reputation: registration certificates, invoices, advertising, press coverage, website history and distribution agreements. For owners abroad, evidence of the brand's recognition among Iranian consumers or trade partners is especially useful.
