In practice, many friends can't tell the difference between invention patent and utility model patent. Should a product, a method or even a graphic declare invention or utility model? Or both? This paper will discuss this and provide the corresponding practical operation.
Generally speaking, many people's understanding of utility models and inventions is often one-sided. Generally understood as follows:
1. All products can apply for patents, including invention patents and utility model patents, that is, as long as they are newly created, they can apply for patent protection.
2. Significant improvement, which is used to declare invention patents for protection; Details and trifles are used for utility model declaration;
3. Invention patents are often patents, while utility models are not patents and are not worth reporting.
Invention patents and utility model patents should be protected as long as they are declared and made public.
Then, since the above views are somewhat one-sided or even wrong, what is the difference between invention and utility model? We might as well look at how the patent law discusses inventions and utility models.
We all know that when applying for a patent for invention, there is also a patent for utility model, also called a small invention or a small patent. It is the object of patent law protection, and refers to a new practical technical scheme for the shape, structure or combination of products.
