What are the conditions for applying for a patent for invention?

Patented inventions must be novel, creative and practical. (1) Novelty 69 Novelty means that no identical invention or utility model has been published in domestic and foreign publications, used publicly in China or made known to the public in other ways before the filing date. The same invention or utility model has not been applied to the Patent Office by others, and it is recorded in the patent application documents published after the application date. (2) Creativity means that compared with the prior art before the filing date, the invention has outstanding substantive features and remarkable progress, and the utility model has substantive features and progress. The invention or utility model for which a patent is applied must be substantially different from the existing technology before the filing date in the composition of the technical scheme, and must be the result of creative thinking activities, rather than the result that the existing technology can naturally obtain through simple analysis, induction and reasoning. Invention is more creative than utility model. Creative judgment is based on the knowledge and judgment ability of ordinary technicians in their respective fields. (3) Practicality Practicality means that the invention or utility model can be manufactured or used and can produce positive effects. It has two meanings: first, the technology can be manufactured or used in industry. Industry includes industry, agriculture, forestry, aquaculture, animal husbandry, transportation and service industry. Industrial manufacturing and utilization refers to feasibility and reproducibility. Second, it must be able to produce positive effects, that is, compared with the existing technology, the invention or utility model for which a patent is applied can produce better economic or social benefits, such as increasing the number of products, improving the quality of products, increasing the functions of products, saving energy or resources, preventing and controlling environmental pollution, etc. (four) other conditions, such as the specification needs to fully disclose the technology for which the patent is applied.
