Legal factors
Patent is a legal protection system, and patent right is a right obtained according to law. The law not only clearly stipulates the acquisition of rights, but also determines the ownership object and protection period of patent rights. Therefore, whether the legal status of patent is stable and how strong the protection is is is the basis that directly affects the value of patent. Without rights, all values are out of the question.
technical factor
In the final analysis, patent protects technology, and for a technology, its technical field, development stage, development degree, advancement, innovation, defense degree, maturity and other aspects have great influence and restriction on its value. Therefore, it has a direct influence and restriction on the patent value.
market factors
If legal factors and technical factors directly determine the evaluation of patent value, then market factors can be said to be a direct verification of patent value. In the final analysis, the evaluation only points to the prospect forecast before entering the market. Whether it has real high value can only be "conclusive" after being accepted and recognized by the market. In fact, the high-value patents on the market at present are widely recognized after the patented products have been listed for many years.
