Our History

We have practiced patent law from 1990s, the earliest days of development of China's patent system.

Our business has advanced together with the fast progress of China's patent industry.  Over the years, we have provided our professional services to multinational companies, like Lenovo, Nokia, IBM, etc., as well as SMEs and individuals of various countries.

Overall, we have handled more than 5000 cases of patent application, prosecution, invalidation, infringement lawsuits, etc.

We distinguish ourselves by our utmost pursuit of quality, high professional expertise and reliability.
