Hello, I'm glad to answer your question. Such patents are mainly divided into invention patents, utility model patents and appearance patents. The application procedure for invention patent mainly includes five stages: acceptance, preliminary examination, publication, actual examination and authorization. The utility model and appearance only need to be accepted, and the three stages of preliminary examination and authorization generally take one week to apply, but the patent certificate will not come down until 18 months. This is a legal procedure. In terms of price, the personal invention fee of 3500 includes application fee, registration fee, printing fee, information fee and annual fee for the first year. If you are a utility model or an appearance patent, it is 1500, including the above contents. The documents you need to prepare are as follows: an application for a patent for invention includes a request for a patent for invention, a specification, a claim, an abstract and its drawings in duplicate. An application for a patent for utility model includes an application for a patent for utility model, a specification, drawings of the specification, claims, abstract and drawings thereof in duplicate. An application for appearance includes: a patent request for design, photos or pictures in duplicate. You can find a cooperative manufacturer or technology transfer.
