Doug is a widely respected litigator and arbitrator with more than a quarter of a century experience handling IP litigation and arbitration in East Asia as well as coordinating global cases.  He is a solicitor advocate of the High Court of the Hong Kong SAR.

Doug has handled the entire gamut of contentious IP cases including raiding factories in China (in the early part of his career); obtaining civil search and seizure (Anton Piller) orders and freezing (Mareva) injunctions; establishing new law in relation to anti-circumvention technologies; running complex multi-jurisdictional patent litigation relating to standard essential patents; and sitting as an arbitrator and appearing as counsel in high technology arbitrations.

His non-contentious experience includes advising on data security and privacy, technology transfer; and, conducting patent and other intellectual property audits.

Doug, who is originally from Australia, studied as an exchange student at high school in Japan and on a Sino-Australian government scholarship at Fudan University in Shanghai. He speaks, reads and write, both Japanese and Chinese.

Doug began his career in IP in Hong Kong in 1993 with a large international law firm. In 2000, he moved to Shanghai, initially on secondment with a local firm and, in 2003, he established and was Managing Partner of his firm’s Shanghai office. He also served for 2 years on the firm’s worldwide partnership council. 

In Shanghai, Doug was ranked as a top tier IP lawyer by all the key directories with one of them describing him as “the best IP lawyer practicing in China”.

From 2011 to 2019, Doug practiced as an intellectual property barrister in Hong Kong SAR appearing as an advocate in the higher courts, including in the Hong Kong Court of Final Appeal. He has been appointed as an arbitrator, mediator, and acted as counsel in numerous high technology arbitrations and mediations. He is also a member of the Hong Kong Inland Revenue Board of Review that hears appeals from decisions of the Inland Revenue Department.
