Singapore law firm Colin Ng & Partners has lost the co-head of its regional IP group, Ai-Leen Lim, to Bird & Bird, which has brought Lim on board in Hong Kong as a partner.

Lim was the chief representative of Colin Ng & Partners' Beijing office and the resident partner of its Hong Kong office. Her new role at Bird & Bird will see her head the firm's IP portfolio management practice in Asia out of both Hong Kong and Beijing.

Lim was previously an assistant registrar of trademarks and patents at the Intellectual Property Office of Singapore and has advised during her career on all aspects of contentious and non-contentious intellectual property work.
