What is CNIPA?
The China National Intellectual Property Administration (CNIPA) is China’s official government body responsible for patent registration and intellectual property protection. As the world’s largest patent office, CNIPA plays a crucial role in fostering innovation and protecting intellectual property rights in the world’s second-largest economy.
At Yucheng IP Law, we work closely with CNIPA to help both domestic and international clients navigate the complex landscape of Chinese patent law. Our experienced team, led by Tingfei Wang, specializes in patent prosecution and has successfully handled thousands of patent applications.
