Why a registered trademark still needs attention
Registration establishes trademark rights, but keeping the certificate is not enough to maintain every aspect of protection.
Further attention may be needed as the way you use the mark changes, your business expands, or approaches.
Actual use and maintenance of the rights matter alongside registration itself.
1. Non-use may leave a registration open to cancellation
Under the Trademark Act, a registration for the relevant may be cancelled if the registered mark has not been used in Korea for a continuous period of at least 3 years without a justifiable reason.
This is known as a proceeding.
Rights do not disappear automatically after 3 years. A cancellation request and a determination of whether the statutory requirements are met are necessary.
What matters is whether the mark and goods actually used correspond to the registration. Use for different goods or a substantially redesigned may require a separate assessment.
2. Keep evidence of actual use
Materials showing the mark on goods or packaging, sales and transaction records, advertisements, and service screens may provide evidence of use.
Simply creating or storing materials does not always establish trademark use in the legal sense. Actual transactions, how the mark appears, the relevant , and the dates of the evidence must be considered together.
It is therefore helpful to keep organized records that show both use and its timing as you operate the brand.
3. Reassess protection when your business grows
An existing registration does not automatically cover new goods or services.
For example, if you expand from a registered product brand into a separate service business, the relationship between the existing and the new business needs review.
An application to register additional designated goods or a separate trademark application may be appropriate.
If ownership changes from an individual to a corporation, or the business is transferred, it is also important to check legal ownership and the registered owner's details.
4. Trademark rights have renewal deadlines
The basic term is 10 years from registration. Following the statutory procedure allows the rights to continue in further 10-year terms.
Renewal can generally be requested during the 1 year before expiry. If that period is missed, a procedure is available within 6 months after expiry. Additional fees may apply, so timely management is advisable.
If registration fees were paid in 5-year installments, the second payment deadline must also be tracked separately.
