Hong Kong trademarks can be registered in the name of individuals or companies, and then mainland companies are authorized to use and conduct business.
But if the trademark is not registered in China, it is not protected. If China has a prior trademark, then you constitute infringement, regardless of the consequences. Just like the cases of Apple and Proview these days, you can contact me if you need to inquire about registration. You can apply in your own name: (there are restrictions, and the scope of the goods you apply for must be within the business scope)
I am Xingye International Consulting, specializing in offshore company registration and international trademark registration in Hong Kong. This is QQ. Welcome to inquire and look forward to cooperating with you.
