  • The term for filing a patent application in Hong Kong
The patent application procedure in Hong Kong consists of two stages. To obtain a patent in Hong Kong, an applicant is required to file an application with one of the three designated patent offices (i.e. National Intellectual Property Administration, P.R.C. (CNIPA), United Kingdom Intellectual Property Office (UKIPO), or European Patent Office (EPO) designating the United Kingdom) and then file a request to record in Hong Kong within 6 months after publication of the designated application by the designated patent office. Additionally, the applicant should file a request for grant within 6 months after publication of the request to record or the grant of the designated patent by the designated patent office, whichever is later.
  • Filing requirements for request to record (stage 1) and request for registration and grant (stage 2) in Hong Kong
Required documents for the first stage:
- request to record;
- applicant’s and inventor’s details;
- copy of the published designated patent application;
- title and abstract of the invention in Chinese and English;
- priority data, if the priority is claimed;
- statement explaining the entitlement to apply for the grant of a standard patent and the prescribed documents supporting that statement if the applicant is not the same as the one in the designated application.

For the second stage, a standard patent application must comprise:
- request for registration and grant;
- copy of published specification of the designated patent;
- title of the invention in Chinese and English;
- statement explaining the entitlement to apply for the grant of a standard patent and the prescribed documents supporting that statement if the applicant is not the same as the one in the designated application.
  • Language of the patent application 

A Hong Kong patent application must be filed in one of the official languages, i.e. English or Chinese. However, the title of the invention together with the abstract has to be provided in English and Chinese. The translation of the abstract into the official language can be filed at a later stage with additional attorney fee.

  • Power of Attorney requirements

No Power of Attorney is required for filing a patent application in Hong Kong.

  • Substantive examination request

The Hong Kong Intellectual Property Department (IPD) does not conduct substantive examination of the novelty or inventiveness of an invention.

  • Grant and maintenance fees

When the formal examination procedure is successfully completed, the IPD grants a standard patent for an invention, publishes details of the granted patent and issues a notice in the Hong Kong Intellectual Property Journal. If a request for registration and grant is not filed within five years from publication of the request to record, the applicant shall pay maintenance fee to keep the application in force until request for grant and registration is filed. The patent renewal fee is to be paid at the time of 3rd anniversary of the filing date of the designated application after its grant date in Hong Kong and annually thereafter.

  • Representation by a patent attorney

Foreign applicants should perform patent prosecution in Hong Kong through an agent, a registered Hong Kong patent attorney.

  • Notes

1. Online Database for Hong Kong Patents Search.
2. Inventions may also be protected as short-term patents in Hong Kong. A short-term patent is a way to protect invention with a shorter validity term (8 years in total). A short-term patent application can be filed directly with Hong Kong IPD. The grant of a short-term patent in Hong Kong is based on a search report from an international searching authority or one of the three designated patent offices (CNIPA, UKIPO, EPO designating UK). A short-term patent application should include only one independent claim.
