Peter Cheung, the director of the Hong Kong Intellectual Property Department (HKIPD), will retire in mid-May.Cheung has been at the helm of HKIPD since April 2011, where he was previously deputy director. Throughout his tenure, he has been actively pushing to develop Hong Kong as a centre for IP trading, arguing that the city's strong rule of law, proximity to China and well-developed financial services make it an ideal location for IP deal-making.
