 China Science started its business in 1984 as an exclusive agent working for and under the Chinese Academy of Sciences, the state-funded national research institute. Our firm then became one of the first few firms granted a special license by the State Council to handle foreign-related intellectual property matters. In the 1990's, China Science became a private firm wholly owned by its shareholders. Since then, China Science has entered into a period of significant growth under the leadership of Ms. Yue Li. As of 2019, there are 300 professionals and staff in total, including 160 patent agents, 18 of whom also possess legal professional qualification. Among them, 85 have been working at China Science for more than 10 years. They currently work in our offices of Beijing, Shanghai, Tianjin, Wuhan, Hong Kong, Osaka, Tokyo, Washington D.C., and Paris.At China Science, we are devoted to providing high quality service to meet our clients' need and maximizing the value of their intellectual property assets in China.

Technical Expertise
Strong technical expertise is what we believe adds values to our clients' demand. A sophisticated level of technical expertise and actual practice experience enables us to put a product or process out of the inventor's ingenuity into an as broad as possible scenario of relevant products and technologies. It offers a powerful benefit to our clients in drafting, prosecuting and even litigating patents. Each and every one of our 160 professionals has a science or engineering degree, with 17% of them having Ph.D. degree and 80% with Master's degree in a wide range of technical disciplines. More than one third of our professionals have had R&D experience in universities, research institutes and industries before they started the patent law practice. Ten patent attorneys held titles of senior research fellows at the Academy back in 1984, and today they are among the most experienced patent attorneys in China. Our technical expertise is further strengthened through continued recruitment of new talents from the Academy and the best universities of the country.

A large portion of our clients are multinational companies from various countries. We have supported their needs to protect, exploit or litigate intellectual property rights in China. We also provide a full complement of patent and trademark agency services to associate firms of more than 20 jurisdictions.

As backgrounds, many of our attorneys had studied, worked or received professional trainings in the United States, Japan, Europe, or Canada, especially in law firms in these countries.
