If I called something YouTube++, is it copyright infringement? Would It need to be YouTubeâ„¢++?
The company name it's registered to doesn't have to be the same, and the name will likely only be used as an AppStore listing
The product is a tool for YouTube..
If your product name reminds a lot of a widely-known brand, then it is a trademark infringement. You better avoid using names such as YouTube, Google, Coca-Cola, and the likes.
