For international businesses and brand owners, Iran’s trademark regime contains a mechanism that cuts both ways: the cancellation of a registered trademark for non-use. It is worth understanding before you enter the Iranian market — or after. Trademark cancellation for non-use matters if you want to clear an unused mark held by someone else. It also matters if you already hold Iranian registrations that you are not actively exploiting. Iran recently overhauled this area through the Industrial Property Act, enacted in the Iranian calendar year 1403 (2024). This note explains how the mechanism works for those approaching it from outside the Iranian legal system.
In short: under Iran’s 2024 Act, an interested party can cancel a trademark that has gone unused for three continuous years. The rule cuts both ways — it clears others’ idle marks, and it puts your own unused marks at risk.
- The trigger — at least three continuous years of non-use, measured from registration to one month before the cancellation request (Article 110).
- Who can act — an “interested party,” a category that includes competitors, quality-control bodies, and trade associations.
- The defence — force majeure, such as war or a pandemic, can justify the non-use.
- When it bites — cancellation runs from the final judgment, not back to the registration date.
The underlying principle
Like many jurisdictions, Iranian law treats a trademark as a right that must be exercised, not merely held. The rationale will be familiar to practitioners elsewhere. Registration is meant to protect marks that are genuinely in commercial use. It is not meant to let a registrant “warehouse” a valuable mark indefinitely and block legitimate competitors from the market. Where a mark sits unused, Iranian law provides a route to remove it from the register and free it for others.
The three-year non-use requirement
The central provision is Article 110 of the Act. An interested party may seek cancellation by proving three full years of continuous non-use. That non-use may be whole or partial, and it covers the owner’s failure to use the mark personally or through an authorized party. The relevant window runs from the date of registration to one month before the party files the cancellation request.
In practical terms for a foreign client: a mark may appear on the register yet be absent from the actual marketplace. If three years have elapsed, you may have grounds to challenge it.
A two-way risk: if you hold an unused mark in Iran
This is the point foreign clients most often overlook. The same provision that lets you clear someone else’s idle mark can work against you. A competitor, or any other interested party, can bring a non-use cancellation action against you once three years of non-use have elapsed. That exposure applies to marks you are not genuinely using, such as:
- defensive registrations;
- marks held for a product launch that never materialized;
- brands parked for future use.
Foreign rights holders are therefore advised to audit their Iranian portfolio, document any genuine commercial use, and be deliberate about marks they are merely holding rather than exploiting.
The force majeure exception
Cancellation is not an automatic outcome, in either direction. A registrant can defeat a cancellation action by showing that force majeure — circumstances genuinely beyond its control — prevented use of the mark. Events such as war or a pandemic are the kinds of circumstances that may justify the non-use. So if someone challenges your own Iranian mark, a legitimate external obstacle to use may protect it. Conversely, if you are the one challenging another party’s mark, you should anticipate that the registrant may raise such a defence.
Who qualifies as an “interested party”
Only an “interested party” has standing to bring the action. Under Iranian law, this category is broader than it may first appear. Alongside parties who count as interested under the Civil Procedure Code, it expressly includes:
- governmental bodies responsible for quality control of goods and services;
- trade or industry associations active in the relevant field.
So a foreign company intending to operate in a sector with an unused registered mark would generally qualify as an interested party. Just as importantly, a competitor in your sector may qualify to act against your own unused mark.
When cancellation takes effect
The timing often surprises those used to other systems. In a non-use cancellation, the effect runs from the date of the final judgment — not retroactively to the original registration date. The mark therefore counts as valid until the court issues the final ruling. This differs from certain other grounds of cancellation, and it has practical consequences for any dispute over the intervening period.

Key takeaways for international clients
Iran’s non-use mechanism is an opportunity and a liability at once. If another party has registered a brand you want but leaves it unused, the law offers a viable route to clear it. Equally, if you hold Iranian registrations you are not using, you should treat them as vulnerable. The essential points to remember are:
- a minimum of three continuous years of non-use;
- the need to establish standing as an interested party;
- the possibility of a force majeure defence;
- the importance of keeping evidence of genuine use for your own marks.
These actions turn on proving (or disproving) a negative — that a mark has not been used — and the procedure is technical. So foreign rights holders are strongly advised to engage Iranian counsel specializing in intellectual property, whether they are pursuing a cancellation or defending against one.

Frequently asked questions
What is trademark non-use cancellation in Iran?
It is a legal action, under Article 110 of the 2024 Industrial Property Act, to remove a registered trademark from the register because its owner has not used it. An interested party can bring the action once the mark has gone unused for three continuous years.
How many years of non-use trigger cancellation in Iran?
At least three full, continuous years. The clock runs from the date of registration up to one month before the party files the cancellation request, and the non-use can be whole or partial.
Who can file a non-use cancellation in Iran?
Only an “interested party.” The category is broad: it covers parties interested under the Civil Procedure Code, governmental quality-control bodies, and trade or industry associations active in the relevant field. A competitor intending to use the mark generally qualifies.
Can force majeure save an unused trademark in Iran?
Yes. A registrant can defeat the action by proving that circumstances beyond its control — such as war or a pandemic — prevented use of the mark during the relevant period.
When does a non-use cancellation take effect?
From the date of the final judgment, not retroactively to the registration date. The mark is treated as valid until the final ruling issues, which affects any dispute over the intervening period.
