Invention refers to the new intellectual achievements with positive significance and technical form created by human beings in the process of utilizing and transforming nature.
Utility model refers to a new practical technical scheme for the shape and structure of products or the combination of shape and structure.
The difference between utility model and invention: 1. The scope of protection is different, the theme of the former can only be products, and the latter can be both products and methods; 2. The creativity requirement of utility model is lower than that of invention patent. One of the purposes of establishing a protection system for utility models is to protect small inventions whose creations are highly inconsistent with the requirements of invention patents; 3. The audit procedure of the former is simpler and faster than the latter.
