A patent registration protects an invention by providing market monopoly over it in exchange of its disclosure to the public. A one-of-a-kind invention developed by a business is a great commercial asset that makes one stand out from others. The monopoly over an invention allows its inventor to maximize the profitability out of it. 

We pay great attention to the drafting of a Patent claim to maximize the scope of protection a Patent registration can apply to your invention. Our Patent services include search, filing and application and renewal to multiple jurisdictions. 

Patent FAQ

What is Patent Cooperation Treaty (PCT)?

Hong Kong is a member under the PCT by the WIPO with another 147 member countries. PCT can be applied within 12 months of your initial filing and so extend the priority to 30 months from the initial filing date to filing your invention at the PCT member countries. PCT is advised if you are intended to file your invention at multiple jurisdictions.

Advantages of PCT:

•    Additional time to claim priority for application in other jurisdictions (Paris Convention gives only 12 months from date of initial filing) 

•    Commercial flexibility for evaluating the chances of obtaining patent and exploiting your invention in foreign countries before paying the national filing fees. 


Patent Procedure

Pre-filing search

Optional and advisable

It is advisable to conduct a worldwide Patent search before filing your application to the Registry. This is to check your invention is not within any claim of any existing Patent.


Claims, descriptions and drawings are required in the application for your Patent specifications.

Claims are what you are claiming under such registration- it lays out the scope of protection that you are entitled to. We spend extra care in drafting to maximize your right.

After filing, there is request for substantive examination, which the Registry will examine your application to check if it meets the corresponding requirements. This stage may take up to  5 years until the Registry issue an examination report.

Short Term Patent requires no substantive examination before grant except an official search report and a much shorter time is expected for grant. 


Note that if you intend to file your patent in other jurisdiction, you have 12 months from the date of initial filing to claim priority. You may consider applying for PCT if you intend to register in a large number of countries. 

Grant and post-grant

The Registry will issue you a notice of grant after the examination report. For which after paying the grant fees, the Certificate of Grant will be issued. 

A Patent offers protection up 20 years from the date of initial filing, subject to renewal annually starting the second year of the grant.
