Considerations before applying for a patent

1. Basics of a patent

You should first familiarise yourself with some basic patent law and principles in order to have some idea as to what a patent is and whether your invention is patentable. You may find some basic information relating to patents here.

Information about patent applications and granted patents is published on the Online Search System and in the Hong Kong Intellectual Property Journal.

2. Prior art search

A patentable invention must be new. You should conduct a prior art search to make sure your invention fulfills this requirement. You may go to the Online Search System and click "About Patent Search" for further details.

3. Self assessment

You may want to carefully assess whether your invention is worth patenting. Here are some factors you may wish to consider:

• Costs of patent application
• Commercial worth of your invention
• Financial and licensing issues
• Time and effort in pursuing patent application and protection
• Complexities of applying for a patent and requisite knowledge and experience in the area
• IP protection strategy

4. Patent Specification

Amongst all the forms and documents required during the patent application process, the patent specification should be the most complex and important one. A patent specification includes the following sections:

• "Description" of your invention which describes the invention and explains a technical problem that your invention solves, and what it does.
• "Drawings" which illustrate the features of your invention.
• "Claims" which are the precise statements of technical features of the invention that you want to protect.

For examples of a patent specification, you may go to the Online Search System. For example, to search for the patent specifications of inventions relating to a “thermometer”, you may go to the patent online search system and look up “thermometer” under “Title of Invention”. The patent specification of a particular invention can be viewed under the heading of “Published Documents” after clicking the title of the invention in the search result list.

Since the patent specification is an important legal document, you are advised to seek professional help from those who have the necessary technical and legal skills.
