How should enterprises choose the type of patent application?

There are three types of patent applications: invention patents, utility model patents and design patents. However, general companies will choose between invention patents and utility models when applying for patents. Enterprises applying for patents must first understand the characteristics of invention patents and utility model patents: 1. What are the characteristics of invention patents? 1. Long protection period of invention patent: 20 years. 2. An application for a patent for invention requires preliminary examination and substantive examination, and the patent right can only be obtained after the substantive examination is qualified. 3. The examination time of the invention patent application is long and the authorization is slow. 2. What are the characteristics of utility model patents? 1. The protection period of utility model patent is short: the protection period is 10 year. 2, the application for a patent for utility model only for preliminary examination, not substantive examination, preliminary examination qualified can get the patent right. 3. The patent application for utility model is granted quickly, usually within 12 months or even less. For an enterprise applying for a patent, if the applicant submits an application for a patent for utility model and an application for a patent for invention on the same day, the applicant can obtain the patent right for utility model in a short time, so that his invention can be protected as soon as possible; If an application for a patent for invention can be granted a patent for invention after substantive examination, the applicant should make a choice. If the patent right of utility model obtained in advance is abandoned and the invention patent right is obtained, then the applicant can obtain a more stable patent right and a longer protection time.
