The creativity of house design is, in understanding, the planning and design of house decoration according to your personal intelligence, which is not a technical means and cannot be patented. In addition, Article 25 of the Patent Law also stipulates that no patent right shall be granted to the rules and methods of intellectual activities.
But your design idea of the house can be presented in the form of design drawings, which can be used as the object of copyright protection. Copyright is different from works protected by patents. Article 3 of the Copyright Law stipulates that copyright protects "intellectual achievements that are original and can be expressed in a certain form in the fields of literature, art and science". According to China's Copyright Law, once the works of China citizens are created, they will enjoy copyright protection. However, in order to further determine the ownership of copyright, you can apply to the National Copyright Center for copyright registration to prove that you are the owner of copyright.
