I was working before the holiday to update our 'sales material'. I have checked the government information related to the HK Government Patent Application Grant, here is some highlight:
The grant was commissioned in 1997 and started the acceptance of application on Apr 1, 1998, since then, an average of 172 applications per year were received, up to Mar 31, 2006, a total of 1374 applications were received. Out of which 546 applications were approved. The status of the Grant as of 2006 is here.
We are lucky to get involved with some of these lucky applicants and our success rate to get the grant is higher than average. Needless to say, it would be helpful to get professional help to fill up forms and prepare documents about the invention.
