The patent law in Hong Kong is based on the Hong Kong Patents Ordinance of 27 June 1997, as last amended on 22 February 2008.
[1] The Hong Kong patent system is independent from the patent system in the People's Republic of China (PRC), in that a "patent granted for Hong Kong SAR takes effect in Hong Kong only and does not provide for protection in the People's Republic of China (PRC)".
[1] As of December 2019, three types of patents for inventions were available in Hong Kong, the "standard patent," the "short-term patent", and the "original grant patent":[2][3][4]
