There are two kinds of patents in Hong Kong: standard patents (20 years as its term) and short term patents (8 years). Under the Hong Kong Patent Ordinance, an application for a Hong Kong standard patent must be based on a Chinese, United Kingdom, European filing or PCT application designating China. The registration procedures consist of two stages. The first stage is to make a request to record a designated patent application within six months after the publication date of the designated application. The second stage is to file a request for registration and granting of the designated patent within six months after the granting date of the designated patent.
Applicants who seek the patent protection of short-term patents or for industrial designs can apply to the Department of Intellectual Property in Hong Kong Directly.
