Can I take someone else's app name as the company name?
It depends. If someone else's APP, such as WeChat, applies for a trademark, then you can't register a company with this name. Another thing is that you can have a common name. If you have a name that is difficult to understand, the industry and commerce will ask you to explain the meaning of the name, and you must explain it clearly. Conversely, if the trademark does not look at the company name, as long as people have not registered the trademark with the name of that APP, but the trademark registration is strict, as long as there are two consecutive words that are the same, it will not be approved.
