Beijing Tongdaxinheng Intellectual Property Agency boasts a large local client base, counting Datang Mobile, China Mobile, consumer electronics company Hisense, and telecommunication equipment company ZTE as some of its active clients. The list of names is also proof of the firm's extensive sector expertise in the telecommunications industry. Patent drafting takes up the bulk of its work and a majority of the applications it handles concern invention patents. The firm expanded the patent team last year by hiring two attorneys to cope with the increasing workload.
