I want to register trade mark name in our country. We found the same name is registered in Japan only (not in our country). I think we can register the trade mark name in our country. This is because we will use the trade mark name to name specific technology and a specific class. In Japan, the same trade mark name is registered in a different class and used for a product name. What are disadvantages of using same name?
Confusion. Once a brand is established people associate it with the products it sells or services it offers. Also, even if it is legal to register it in your own country, you could very well have problems should you ever want to branch out in the future. It's always best to try to come up with something unique and identifiable.
