1. Enterprises established less than one year (not fiscal year, but calendar year, 365 days).
2. Enterprises whose registered place is not in Chinese mainland.
3. Enterprises in eight fields are not supported by the state (such as tobacco manufacturing; Accommodation and catering industry; Wholesale and retail trade; Real estate industry; Leasing and business services; Entertainment industry; Other industries specified by the Ministry of Finance of People's Republic of China (PRC) and State Taxation Administration of The People's Republic of China).
4. The technical content of intellectual property rights is not high. The adoption period of utility model patents is about one year, and the adoption period of invention patents is longer, which takes 1 year and a half to three years. Most enterprises with insufficient intellectual property rights are eager to apply for high fees. The fastest way to ensure that they have independent intellectual property rights is to choose soft application. Enterprises apply for soft products only for high declaration, which has low correlation with intellectual property rights, and even the soft products are completely out of touch with the key technologies of R&D projects and products, resulting in low intellectual property scores of enterprises.
