New Patent System in Hong Kong

By Evelyne Yeung


The Patent (Amendment) Ordinance 2016 and the Patents (General) (Amendment) Rule 2019 will come into effect on 19 December 2019.  It marks the history of Hong Kong that she will have her originally granted patent registration for the first time.


Highlights of Reform of Patent system in Hong Kong

The existing patent system, namely, standard patent and short term patent, will be retained with some refinement of short term patent. 

The new feature of the reform patent system is the introduction of the original grant patent system and some other issues relating to the existing patent system. 

1. Standard patent by original grant (“Standard Patent (O)”)

It is an entire new patent system in Hong Kong.  The applicant can file their standard patent (O) application directly in Hong Kong without first filing the patent application in designated patent office. 


New features:

(1) Direct filing of the patent application with or without priority claim.

(2) Apart from checking minimum requirement on formality, the applicant will need to request for substantive examination within 3 years from the application date or priority date.

(3) The patent will be substantively examined as to its patentability, namely, novelty, inventive step and industrial applicability by examiner in Hong Kong. 

(4) If the examiner considers that the patent lacks of novelty and/or inventive step, he will issue examination notice (and/or further examination notice), and the applicant has to deal with the official objection.  The application will be granted if the applicant can overcome all the objection or it may be provisionally refused if the application does not fulfil the formal requirement.

(5) If the applicant cannot overcome the official objection after examination, provisional refusal will be issued, which is subject to review requested by the applicant. 

(6) Applicant may request for review on provisional refusal notice, and the examiner will issue review opinion (or one or more further review opinion), and the applicant has to overcome the objection.  If the objection can be overcome, patent will be granted. Otherwise, the examiner will issue final refusal notice, subject to appeal to High Court.


2. Standard patent by re-registration (“Standard Patent (R)”)

Standard Patent (R) application in Hong Kong is retained.  The procedure is the same as the existing system, i.e. the application must be based on a designated patent application filed in China, U.K. or Europe designating U.K.  It may simply regard this system as a re-registration system.  The substantive examination of the Standard Patent (R) is conducted by the designated patent office.

The application process is divided into two stages, i.e. 1st Stage - Request to Record must be filed in Hong Kong within 6 months after the date of publication of the designated patent and 2nd Stage - Request for Registration and Grant must be filed in Hong Kong within 6 months after the publication of the request to record in HK; OR, the date of grant of the designated patent, whichever is later.  No grace period is allowed for 1st Stage or 2nd Stage filing.


3. Short term patent (“STP”)

Under the current system, STP application can be filed directly in Hong Kong, subject to examination on the formalities and submission of a search report issued by competent patent registry, e.g. China National Intellectual Property Administration (“CNIPA”).  Proprietor to establish the validity of the patent in enforcement proceedings before the court.  The STP is retained with refinement as follows:


New features:

(1) The application can include 2 independent claims instead of 1 independent claim.

(2) Proprietor or interested party can request for post-grant substantive examination of the short term patent.  If the proprietor wishes to commence enforcement action of an unexamined patent, it is a pre-requisite to have certificate of substantive examination.

(3) If the proprietor cannot overcome the objection raised in the examination notice issued against the short term patent, the examiner will issue provisional revocation notice of the patent, subject to appeal to High Court.

(4) When making a threat of infringement proceedings against a person, the proprietor should furnish with that person the basic patent information.  Otherwise, the threat may be regarded as groundless and a party aggrieved by the threat may be entitled to seek relief.
