Check Trademarks

If you need to check trademarks, you’ll want to run the search before you try to obtain trademark protection on your mark. This search is important so that you don’t infringe upon anyone else’s trademark rights. If you don’t find anything on prior trademarks registered, you’ll still want to run a search in the public domain as any mark being used does in fact have common law protection. Therefore, if you run a search and clearly see that your mark is already in use, then you cannot use it. Specifically, there are 45 unique trademark classes that are identified in the NICE classification for trademark, which can be found on the World Intellectual Property Organization (WIPO) website. Each trademark class represents a different set of goods and services.

Trademark Already Being Used

If, prior to obtaining protection over your mark, you identify that the mark is already protected and is being used by someone else, then they have priority. You cannot seek protection over that mark or even use that mark. Furthermore, even if that person or business doesn’t have official trademark protection, they do in fact have common law protection. Therefore, you cannot use that mark if you run a search in the public domain and find out that the mark is being used. This common law usage can also help you. If you begin using your mark, but don’t have official trademark protection, you still have common law protection. Therefore, anyone else beginning to use your mark can be found guilty of infringement if that person knows or should have known that the mark is already being used.
