Is there a substantive examination of the utility model patent?

The first protection object is different: the utility model only protects the shape and structure, in other words, it needs a specific structure, and the invention can be structure, method, use, etc.

The second protection time is different, the utility model is 10 years, and the invention is 20 years.

Third, the difficulty of authorization is different. The utility model does not need substantive examination and can be authorized in less than one year. Inventions need the creativity of examiners to search and review, and authorization may take 2-3 years. However, the relative utility model rights are not stable enough and easy to fail. The invention is relatively stable.

The number of utility models is a little more, because it is easy to authorize, so some enterprises apply for utility models in large quantities in order to evaluate high-tech or obtain policy support.
