You can apply. The utility model can be applied whether it is improved or not, and the possibility of authorization is very high, because China does not conduct substantive examination and retrieval of utility model patents. As long as your application documents meet the formal requirements, you can get authorization, that is, there is no error in the format, and the scheme can be realized. Examiners don't do searches and comparisons. It's easier if you just want to be informed. I am a patent worker. If necessary, you can contact me and get your certificate.
