Common prosperity is the essential feature of Chinese modernization. Intellectual property law provides equal opportunities for wealth creation by protecting market franchises for innovations, and encourages society to continue to innovate and create wealth. The market-oriented incentives and rights restriction rules of the intellectual property system for scientific and technological and cultural innovation ensure that the whole society benefits from intellectual achievements, promote the common prosperity of the people’s material and spiritual life, and embody the legal mechanism for sharing social innovation achievements under Chinese-style modernization.
