For invention patents, except for some invention patents that need to be kept confidential, general invention patents need to go through the stages of acceptance, preliminary examination, publication, actual examination and authorization announcement. In general, it will be announced 18 months after acceptance, and then the actual examination stage will be carried out. It usually takes about 3 years to get authorization, but it does not rule out a longer time.
In order to speed up the time limit for obtaining the patent right, we can apply for publicity in advance, so that it can be made public after passing the preliminary examination, and then enter the actual trial stage, which can speed up the progress of authorization. In addition, in some special circumstances, such as several cases stipulated in the Measures for the Administration of Patent Priority Examination, a request for speeding up the examination can be made.
Extended data
The utility model patent is one of three kinds of patents (invention, utility model and design), and utility model refers to a new practical technical scheme for the shape, structure or combination of products. The patent law requires lower creativity and technical level of utility model than invention patent, but it has great practical value. In this sense, utility models are sometimes called small inventions or small patents.
The utility model is different from the invention in that:
1. The utility model is limited to products with a certain shape, and cannot be a method or product without a fixed shape.
2. The utility model is not too creative, but it is 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.
