Invention refers to a new technical scheme proposed for a product, method or its improvement. Invention, utility model and design together constitute the object protected by China's patent law.

As a kind of intellectual property, invention patent naturally has the universal characteristics of intellectual property, namely timeliness, regionality, impersonality and exclusiveness.

Invention patents cover a wide range, including two types:

1, product invention;

2. Method invention.

Product invention refers to the creation of articles containing new technical solutions. For example, inventions made by improving machines, equipment, tools, articles, etc.

Method invention refers to the new steps and methods of using, manufacturing or regularly inspecting products. For example, it is suitable for processing methods, testing methods, manufacturing processes, etc.

An invention can be a new product or method, or an improvement of an existing product or method. At present, most inventions in China are improvements on existing technologies, such as adding new technical features or combining some technical features to existing products. As long as this addition and combination can produce new technical effects and solve technical problems, it belongs to invention-creation and can be protected by patent right.
