1. What are the criteria for applying for an invention patent? How to submit an application? The criteria for applying for a patent for invention are novelty, creativity and practicality. When submitting an application, you need to prepare sufficient materials, such as patent technical disclosure, copies of the front and back of the designer's personal ID card, copies of the company's business license stamped with the company's official seal, copies of personal ID cards, personal income certificates, etc. Novelty means that the invention does not belong to the prior art; Before the filing date, no unit or individual has filed an application for the same invention with the patent administration department of the State Council, and it is recorded in the patent application documents published or announced after the filing date. Creativity means that the invention has outstanding substantive characteristics and remarkable progress compared with the prior art before the filing date. Practicality means that the invention can be manufactured or used and can produce positive effects. Existing technology refers to the technology known to the public at home and abroad before the filing date. Therefore, novelty, creativity and practicality are the necessary conditions for granting the invention patent right. The application procedure for invention patent includes seven stages: application, acceptance, preliminary examination, publication, substantive examination, authorization and announcement. To apply for a patent, the prescribed patent application documents shall be submitted to China National Intellectual Property Administration. The application documents must be in written or electronic form and filled in in the prescribed format. The definition of invention in the second paragraph of Article 2 of China's Patent Law is: "Invention refers to a new technical scheme proposed for a product, method or its improvement." The so-called products refer to all kinds of new products that can be manufactured in industry, including solids, liquids and gases with certain shapes and structures. The so-called method refers to the method of processing raw materials and making various products. The invention patent does not seek the technical achievements that can be directly applied to industrial production through practice, but it can be a solution to technical problems or an idea with the possibility of industrial application. However, this technical scheme or idea cannot be confused with a simple topic or idea, because a simple topic or idea does not have the possibility of industrial application. Invention refers to a new technical scheme for a product, method or its improvement, which mainly embodies novelty, creativity and practicality. Patent inventions are divided into product inventions (such as machines, instruments and equipment, appliances) and method inventions (manufacturing methods). To sum up, to apply for a patent, the designer of an invention must first determine whether the product can play a certain value in the market and whether there are innovations that others do not have. Only when these characteristics are determined, the Patent Office will accept his request for a patent for invention, but when submitting the application, he still needs to prepare all kinds of proof materials related to the invention in advance.
