About Patent Law in China
Patent law in China is governed by the People's Republic of China (PRC) Patent Law, which provides the legislative framework for patent protection. Managed by the China National Intellectual Property Administration (CNIPA), the law is designed to grant patents for inventions, utility models, and designs. As a signatory to international agreements such as the Paris Convention and the Patent Cooperation Treaty (PCT), China's patent system follows international standards while reflecting local economic and technological development policies.
