1. Short product life cycle: In patent application, because the protection period of utility model patent is ten years and invention patent is twenty years, it is a good choice to apply for utility model patent under the condition of short product life cycle.
2. Continuous improvement and upgrading of product technology: it usually takes 2 -3 years to grant an application for a patent for invention. Relatively speaking, the time for granting utility model patents is relatively short, only 6-8 months. If the product technology has been continuously improved and upgraded, patents with short authorization time are more suitable.
3. The invention and innovation of the product are few, and the innovation is mainly improvement: because the utility model patent does not require high creativity, mainly practicality. If the idea is very strong, it is suggested that you can apply for an invention patent.
Patent applicants can decide according to the situation and characteristics of their own products, and if appropriate, they can also apply for patents at the same time (both invention patents and utility model patents).
