Hong Kong—patenting an invention

This Practice Note was originally written for LexisAdvance® Practical Guidance Hong Kong.

Hong Kong is a special administration region of the People’s Republic of China (Mainland China). Under the one-country two-system regime, Hong Kong has its own patent laws and a system of patents which is separated from that of Mainland China.

The Intellectual Property Department (IPD) of the Hong Kong government is responsible for the administration of application, registration and maintenance of patents.

There are two types of patents in Hong Kong, namely:

  1. standard patents, and

  2. short-term patents

The Paris Convention and the Patent Co-operation Treaty (PCT) are effective in Hong Kong due to the membership of Mainland China. The agreement on Trade-Related Aspects of Intellectual Property (TRIPS) has been implemented in Hong Kong due to the World Trade Organisation membership of Hong Kong.

A short-term patent application can be a priority founding patent application under the Paris Convention or TRIPS but not a standard patent application.

Patents can be in the Chinese language or in English.


The principal legislation is the Patents Ordinance (Cap 514) (PO) and the Patents (General) Rules (Cap 514C) is the subsidiary regulation.

Matters relating to the infringement of patents are under the exclusive jurisdiction of
