Founding and managing partner of SITAO Dragon Wang is a dual-qualified patent attorney and litigator, with significant in-house and private practice experience. Wang’s representation of big-name clients such as Ericsson, Sony, Apple and Seiko Epson in patent actions, and strategic advice, justifies his place in the Rankings.

Key matters:

• VoiceAge EVS: Standard-essential patent (SEP) cases

In June 2025, the Fuzhou Intermediate People’s Court of Fujian Province issued a first-instance judgment in favour of SITAO’s client VoiceAge EVS. The court ruled that HMD Global had infringed VoiceAge EVS’s patents by selling certain Nokia handset models and failed to fulfill its duty as a technology implementer to negotiate a licence on FRAND terms.

The case is part of a wider enforcement strategy by VoiceAge against HMD, in which VoiceAge has secured favourable decisions in Germany, Brazil and other jurisdictions.
