II. Types of invention patents
Inventions can be divided into product inventions and method inventions.
Product inventions include all things created by people, such as inventions of machines, equipment, parts, instruments, devices, appliances, materials, composites, compounds, etc. Methods Inventions include all methods that make use of natural laws, which can be divided into manufacturing methods and operating methods, such as inventions made in processing methods, manufacturing processes, testing methods or product use methods.
An invention protected by the patent law can also be an improvement of an existing product or method. Most inventions are improvements on the existing technology, such as new combinations of certain technical features and new choices of certain technical features. As long as this combination or choice produces new technical effects, it is an invention that can be patented.
