Personally, I suggest you don't say the name you want to apply for on Baidu. If this name can be applied for and you haven't had time to protect it, it is easy for others to register first, so it will not be worth the candle.

If in doubt, you can consult a professional organization. It is free to inquire about domestic trademark registration.

If you have anything unclear, you can always find me at Baidu Hi.
