The mainland's entry to the WTO would help Hong Kong's battle against trademark and copyright infringement, the SAR's intellectual property chief said yesterday. Director of Intellectual Property Stephen Selby said Beijing would have a duty to enshrine the spirit of international agreements to protect intellectual property rights after WTO entry. Mr Selby said his office had urged Beijing to allow Hong Kong agents to represent local clients when applying for intellectual property rights on the mainland. 'I am confident that, with the upcoming accession to WTO, these issues will gradually, if not immediately, be able to be dealt with,' he said. Mr Selby said his office would conduct an intellectual property conference jointly with Beijing in April to exchange experience and discuss problems faced by small and medium-sized companies doing cross-border business. During a visit by Mr Selby to Beijing last week, his mainland counterpart had invited the office to arrange a meeting of experts to discuss greater co-operation. Talks could include ways to verify mainland authorisation letters issued to local factories for the manufacture of compact discs.
