Changes for our patent services in Hong Kong

As Hong Kong is one of the largest ports in the world and a home to some of the most popular trade shows (such as Hong Kong Electronics Fair, the Hong Kong Optical Fair, and the Hong Kong Housewares Fair) globally, it is an important jurisdiction to protect your intellectual property, especially when you enforce your patent, a patent certificate is a required title document for making a complaint to the Legal Adviser of fairs about patent infringement by another exhibitor. However, patents registered with the Chinese Patent Office do not automatically receive protection in Hong Kong.You should register your patent separately in the two places in Mainland China and Hong Kong, as there are separate systems of registration and protection.

There are three types of patents in Hong Kong. One is called standard patents. Another one is called short-term patents. Yet another one is called design patents. The period of protection of a standard patent can be renewed annually after the end of the third year, up to maximum term of 20 years. Protection under a short-term patent is renewable after the end of the fourth year, up to a maximum term of eight years. The period of protection of a registered design is renewable for periods of five years, up to a maximum of 25 years.

As to a standard patent, its grant is based on the registration of a patent at the European Patent Office designating the United Kingdom, a United Kingdom patent or a Chinese invention patent, called designated patents. A standard patent application is made in two steps:

Step 1. Filing a Request for Recordal within 6 months from the publication date of the patent application filed at one of the designated patent offices as described above; and

Step 2. Filing a Request for Registration and Grant within 6 months from the issue date of the patent.

The grant of a short-term patent in Hong Kong is based on a search report from an International Searching Authority, the European Patent Office, the United Kingdom Patent Office, or the Chinese Patent Office.

Opening an Office in Hong Kong enables us to file patent applications in Hong Kong electrically, which helps us extend our services in Hong Kong with more flexible and competitive fees.
