that depends on what RG is. What you're talking about doesn't usually happen. Trade nouns or common product names cannot be registered. For example, EG is a registered waterproof coating. Then that company must be the original research and development unit. But that's impossible. This kind of behavior constitutes infringement, but I still don't quite understand how he can apply for a trademark with a common industrial name. Anything can hi me. Or 1311557477@QQ.COM.
