Under the condition of modern socialized mass production, the technological foundation of enterprises is always in revolutionary development and change. The breakthrough and gradual accumulation of technological innovation often bring about a series of important changes such as concept innovation, organization innovation, management innovation and system innovation. Among the existing legal protection and incentive means, the acquisition, maintenance and protection of patent rights are the safest, lasting, reliable and effective basic measures to protect the technological competitiveness of enterprises. Patent right is essentially a kind of property right incentive, which enables technical resources to be confirmed and defined with legal rights. The patent strategy gradually formed in the actual implementation and operation of patent rights provides the most sufficient space for this kind of property right incentive. Patent strategy can be divided into national patent strategy, regional patent strategy, industry patent strategy and enterprise patent strategy.
