Comrade Deng Xiaoping took a broad and long-term view in 1984 and gave the final word to the decisive decision that "the patent law should be passed as early as possible", which paved the way for the establishment and development of China's patent system in the end.
In 1982, the 24th Meeting of the Standing Committee of the Fifth National People's Congress delibrated and adopted the Trademark Law, which pioneered the legislation of intellectual property rights in China and marked that the law construction of China's intellectual property had entered a brand-new stage. (that's why our website uses 1982)
The Patent Office of the People's Republic of China (predecessor of National Intellectual Property Administration, PRC) was established in 1980, and China joined WPO.
China promulgated Provisional Regulations on the Protection of the Right to Invention and Patent, and Provisional Regulations on Trademark Registration and other intellectual property laws and regulations in 1950.
The International Trademark Business Department was established on October 1, 2014.
Shanghai Renke Law Firm (litigation practice) was established in Shanghai on January 15, 2013.
Yajia Intellectual Property (trademark, patent) was established in Beijing on September 18, 2013.
Another 15 years of hard work, and we will turn Yajia into a world-leading legal-service institution with Chinese characteristics for intellectual property. Our clients will be ahead of the rest of the world in the creation, use, protection and management of intellectual property, which will become the powerful technological and resource support for business operations and development.
To become the cradle of young leaders who are both virtuous and intellectual, and to help more young people better fulfill their life value
