Frequently Asked Questions
Should I file my trademark in local characters?

Yes, for a broader and stronger protection in South Korea, we recommend registering your trademark in local characters.

If the trademark is registered only in its original version (Latin characters), the protection does not always properly protect its equivalent in the local language. This means that a third party could use or register the same trademark (or a similar one) in local characters.

In additional to the legal benefits, the registration and use of the trademark in local characters can also have commercial benefits. The public in South Korea will recognize your brand more easily if they are able to read and correctly pronounce the mark.

Registering your trademark in its original version, as well as local transliteration/translation, will provide a greater protection from any possible infringements.

Is there a time frame for the trademark registration approval?

The average time frame for the registration approval is 16 months, if no objections or oppositions arise.


If I register my trademark in South Korea, do I have protection in other territories?

No. The mark will be protected only in South Korea.

Do I need to sign a Power of Attorney?

Yes. A power of attorney is needed to complete the process of trademark application.

Are there any benefits from a pre-filing use of the trademark?

Pre-filing use has minimal benefits since rights are primarily established through registration. However, it will help the applicant demonstrate distinctive qualities of the mark and win over objections on the basis of non-distinctiveness.

Will there be problems in case I don’t use my trademark after registration?

Yes. Third parties may possibly appeal for the cancellation of the trademark on the ground of non-use.
