 Frequently Asked Questions
Trademark Registration
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.

Basic Questions
What is a trademark?

A trademark identifies products and services in order to distinguish them in the market. The name, the verbal element, is not the only component that distinguishes a trademark; figurative elements such as logos, design, images, colors and sounds also create an identity that can be protected through trademark registration.

 With the registration, the owner (person or company) becomes the owner of the trademark. The registration is given for a particular country/territory, for certain products or services and for a specific term. While the registration is in force, only the owner may use the trademark in the market where the trademark is registered.

 Some symbols to consider:

® Means the trademark is registered.

TM Some countries use this symbol to show that the trademark has been filed at the trademarks office and is still undergoing the registration process.

SM Some countries use this symbol to show that the service mark has been filed at the trademarks office and is still undergoing the registration process.

What is the difference between a trademark, patent and copyright ?

There are many ways to lay claim to your work. Trademarks, patents, and copyrights offer protection for owners of intellectual property. A trademark helps people find your goods and services. When recognized as a registered mark, it protects your right to exclusively use the image, logo, phrases, or words to distinguish your goods or a service in the market.

patent safeguards ideas and inventions. It gives a creator or inventor exclusive rights that prevent other people from making, using, or profiting in any way from an invention or creative innovation without the consent of the inventor.

You cannot patent an idea because we all have them. You must materialize your concept into a tangible invention, innovative product, device, or process that offers new solutions to a problem to secure a patent.

Copyright protect published, performed, or printed creative works. People who produce artistic or musical work seek to protect their “right” to stop others from “copying” what they do. Copyright protection protects any original creative works of authors including:

  1. a) artwork (2 or 3 dimensional),
  2. b) photographs, graphic drawings, and designs as well as other forms of creativity;
  3. c) songs, music, and sound recordings of all kinds;
  4. d) books, manuscripts, publications, and another written work; and
  5. e) plays, movies, shows, and other performance arts.


A trademark, patent, or copyright are all examples of ways you protect your intellectual property. Your right to control and benefit from your efforts are increasingly important in our global economy. Registering a formal claim to your property is a critical step in protecting what you own.

What is the difference between TM, SM, ® and other symbols?

You recognize a registered trademark by the symbol of a circle-R following the trademark name or graphic image. Various typographic symbols show copyrights and patents. The presence or absence of a symbol does not change the validity of the registration, but a best practice is to use a circle-R or circle-C for copyrights every time you mention your intellectual property in print. These symbols give legal grounds for claiming damages in trademark litigation. The following is a list of some typical marks you can use on a web page, in written content, or even in a marketing letter.

  • TM: The TM sign shows the brand name for an unregistered trademark classified as a product (classes 1 to 34). The owner uses this sign to mark what they believe is their brand mark.
  • SM: The SM sign is identical to the TM sign except it designates a service mark (classes 35 to 45).
  • ®: ®: Use the ® symbol once you register a trademark or service mark. It shows that the country authority has approved the registration.
  • ©: Use the © symbol to mark a copyright. The word copyright is substitute sign for Follow it with the year of the publication and owner's name. Use it whether the work has obtained copyright registration or not.
  • Patent Pending: The phrase Patent Pending shows that you filed a patent application but cannot guarantee the application's approval.
What are trademark classes?

Trademark Offices around the world use classes to divide commercial products and services into defined categories.  When you apply for your trademark to protect your brand, you must define the class or classes that you believe are best describe your business activity. 

There are 45 classes – 34 for products and 11 for services – which countries from around the world have standardized for international use under the "Nice International Classification".

These classes group all known products and services. You can register the same trademark if there are similar classes, for example, you may register the trademark KING for computers in class 23, and you can also register the same trademark in class 24 for cosmetics. 

Trademark protection only extends to commercial use within your specified classes.  It is possible, then for two entities conducting business in different classes to use the identical or similar trademarks and for each entity to enjoy full trademark protection in their respective classes. You can choose multiple classes under which to conduct business if you feel the protection must extend beyond only one class.

You can perform a search of your class with the following tool Trademark Class Search

Trademark Search
Why do I need to perform a trademark search?

Once you have a product or service and think you have a name for it, how do you know you can use it as your own? What happens if you unintentionally use a registered trademark name? In the United States, under what common law, people can lay claim to a mark if they use it. It is not necessary to formally register a trademark. This fact and the sovereignty states have over the creation of chartered business entities and trade names, makes a trademark search imperative before one spends time and money registered a trademark.     

Too many people use a name without knowing if they have legal coverage, and they put up big marketing campaigns with names that later they find they cannot use. Performing a Comprehensive Search Study before you decide to register your brand mark is a wise decision especially when you consider future risks of litigation. 

It is a good idea to conduct a Study before you start doing business with a trademark.  It may not be in your best interest to use a mark if another company is already actively conducting business in the same class.  That company may be able to object to your use of the trademark and prohibit you from using the mark in a court of law.

What is a preliminary trademark search?

Your preliminary trademark search is an important first step before you spend time and money considering whether to apply for a potential trademark or not.

If you have trademark experience, you can use free online resources like our Trademark Searchengine, or the Trademark Electronic Search System(TESS) offered to the public by the US Patent and Trademark Office(USPTO) to search for existing marks that are identical to your planned trademark. While preliminary trademark searches are a critical part of your registration process, a successful search that show no conflicts with identical marks does not necessarily mean the Trademark Office will not reject your registration application.
