Abstract:Aabstract idea exception principle is a basic principle of the Patent Law.In the context of the combination of abstract idea and technical solution, we must determine how to determine the patent eligibility of an invention. We should break away from the traditional theory of patent law,which based on the physical nature of an invention, so as to analyze eligibility of the technical solutions. There are two paths when abstract idea was combined with technology solution: the implement of an abstract idea and the application of an abstract idea. On the basis of this distinction, by analyzing the logic construction of the invention,the patent of the technical scheme is judged.
