Patents are divided into invention patents, utility model patents and design patents. Because your design is not innovative in function, but different in artistic design, you can only apply for a design patent. Whether it can be passed depends on the opinions of the patent examination department. If you are not satisfied with their opinions, you can apply to the Patent Reexamination Board for reexamination.
The copyright of your design, no matter how deep the patent application, is yours. If someone plagiarizes your design or artistic style, you can ask the other party to bear the responsibility for copyright infringement. You can ask the other party to apologize, pay royalties, stop the infringement and so on. If no agreement can be reached or the amount of compensation can not be reached, you can go to court to protect your legitimate rights and interests.
