Technical expertise

A sophisticated level of technical knowledge and practical experience enables us to imagine what stems out of an inventor’s ingenuity being used in as many relevant technologies as possible. This approach offers a significant benefit to our clients when drafting, prosecuting and litigating patents. Every one of the firm’s 160-plus professionals has a science or engineering degree, with 80 per cent holding a master’s and 17 per cent a PhD in a wide range of technical disciplines. More than one-third of our professionals have worked in R&D in universities, research institutes and industries before starting their patent law practice. Our technical expertise is further extended and strengthened through the continued recruitment of new talent from China’s most prestigious universities.

International experience

CSPTAL’s attorneys have extensive experience working with overseas companies and organisations. A large portion of our clients are multinational companies from every part of the world, which we support to protect, exploit and litigate their IP rights in China. We also provide a full complement of patent and trademark agency services to associate firms all over the world.

Many of our attorneys studied, worked or received professional training in the United States, Japan, Europe and Canada, especially in law firms. We also have a policy of sending our attorneys on secondment to foreign law firms or clients’ sites abroad to keep abreast of developments in IP practice in important jurisdictions, and to better understand clients’ needs.

It sets forth the standards of service and organises mandatory training programmes to ensure that these standards are met.
