Explain Trademark Search Service

What Services Can I Use to Search Trademarks?

I’m thinking of registering a trademark, but if it doesn’t show up on Google, can I register it?
Not necessarily. There are cases where a trademark has been registered even though it has not yet been released to the public, and there are also cases where a trademark has not been registered even though you find the use of the trademark from a Google search.
I see. I’d like to know if there is a service that can search to see if it’s trademarked.

To find out if the name of a product or service is already in use in the world, you can use search engines such as Google or Yahoo! However, the results alone do not tell you whether a trademark has been registered or not. Therefore, it is necessary to search whether a trademark has been registered or not.

This article describes the services (search databases) that allow you to search trademarks, as well as their costs and features.

Free Services to Search Trademarks

For trademark searches, there are many services available on websites. Some of these services are free of charge, and the sites are operated by government agencies, private companies, and patent firms. Here are some of the main ones.

AmazingDX (Free Trademark Search)

Amazing DX is a web service operated by our firm. You can search trademarks for free without prior registration.

By entering the trademark to be searched and checking the target goods/services, the search results are displayed in an easy-to-understand manner. Even beginners can use this service with ease.

Amazing DX allows you to request a trademark application online directly after the trademark search. (Registration is required for the application procedure.)

Patent Information Platform: J-PlatPat (all services on the site are free of charge)

This is a free search database operated by the Industrial Property Information and Training Institute. You can search not only trademarks, but also patents, utility models, and designs, and check information on examinations. Although it is not recommended for beginners, as searching and checking results requires a certain level of knowledge. You can use the database by referring to the operation manual.

Paid Services to Search Trademarks

Paid search services exist for professionals with trademark expertise. There is often a monthly fee. This service is mainly chosen by companies, search firms, and patent firms because it allows searches using more advanced functions. This requires a high level of skill to use the system.
Major providers include Infosonor, Japan Patent Data Service, Clarivate Analytics, and Intermark. If you are interested, please refer to each company’s website for details.

Trademark Search Services Including Foreign Countries

Databases for trademark searches provided by international organizations also exist. Some of the main ones are listed below.

Patent Offices of Various Countries

For example, in the U.S., China, Korea, and Taiwan, the websites of the respective national patent offices provide a trademark search service similar to “J-PlatPat” in Japan. Similar search services are often provided in other countries as well. If you are interested, please visit the website of the Patent Office of each country.
