First of all, the core of the patent system is to exchange publicity for protection, so to obtain patent authorization, the technical scheme must be made public.
The perpetual motion machine is not practical and can not be patented. If a technical scheme is to be authorized, the implementation method must be made public. Specifically, a person skilled in the art can implement a patent according to the patent specification and achieve the technical effect described in the patent. If the examiner thinks that it cannot be realized, the patent right will not be granted.
Patent protection is realized through patent law. No one may exploit the patent without the permission of the patentee, otherwise it will be patent infringement and illegal.
To improve the patent, if the new technical scheme is novel, creative and practical compared with the original patent, the patent can be granted. Specific standards are recorded in the Patent Law and its detailed rules for implementation and review guidelines.
Patent protection is regional, such as the patent right obtained in Chinese mainland, which is not protected outside the scope.
