1. How long does it take to apply for a utility model patent?
According to the provisions of China's patent law, utility model patents generally go through the following procedures from application to authorization:
1. The applicant provides technical disclosure and entrusts a patent agency to write application documents. The agent shall, according to the requirements of the patent law and the applicant's invention content, write the application documents with the largest protection scope as far as possible. During the communication confirmation, it usually takes 10 days to about 20 days.
2. After writing the application documents, submit the application documents, obtain the notification of acceptance from the Patent Office, and determine the application date;
3. The Patent Office will formally review the patent application documents for about 3-8 months, and issue an authorization notice after the first trial is passed;
4. The applicant shall go through the formalities for obtaining the patent certificate;
5. It takes about 2-3 months to get the patent certificate.
The whole process lasts about 1 year, and the specific time depends on the examiner's review speed and the details of the applicant's disclosure of information.
2. What's the difference between utility model and invention?
First, the utility model is limited to products with a certain shape, and cannot be a method or product without a fixed shape; Second, the utility model is not too creative, but it is very practical.
In view of the low requirement of utility model for creativity, people generally call it small invention and small creation. However, it should be understood that for highly creative inventions, as long as they are the protected objects of utility models, they can also apply for utility model patents.
The shape of a product refers to the definite spatial shape that the product has and can be observed. The technical scheme proposed for product shape can be the technical scheme proposed for product three-dimensional shape, such as the improvement of cam shape and cutter shape; It can also be a technical scheme of two-dimensional shape of products, such as the improvement of sectional shape of profiles.
The structure of a product refers to the arrangement, organization and interrelation of various components of the product. The product structure can be either a mechanical structure or a circuit structure. Mechanical structure refers to the relative position relationship, connection relationship and necessary mechanical cooperation relationship between components that make up a product, and circuit structure refers to the determined connection relationship between components that make up a product.
