|1. Provisional Patent
A relatively simple application
which does not require listing of claims. This type of application is available in the USA only. No examination will be done for
such application. Attorney time could be minimal if so desired. The provisional
filing will however affect future "regular" application which must be made
within 12 months from the date of the provisional filing.
2. PCT (Patent Cooperation
A treaty under which a single
patent application filing may be made that will preserve the right to file
separate patent applications in member countries (over 40) within 30 months
from the date of the PCT filing.
3. Patent Terms :
In most cases, 20 years from the first filing date.
4. Usual budget for patents:
- US regular patent: HK$250,000.-
- Chinese patent: HK$50,000.-
- Hong Kong short patent: HK$25,000.-
- PCT registration fee: HK$15,000
(designating *ALL* states)
The actual cost depends on the complexity of the technology
, the number of claims, the preparation of the disclosure document as well as the
attorney time needed in processing the application.
