If I have filed separate patent applications in two designated patent offices seeking protection for the same invention, can I file requests to record both designated patent applications?
You can file requests to record both designated patent applications. But under sections 91(1)(f) and (4) of the Patents Ordinance the court can revoke a patent the application for which is filed before 19 December 2019, if it is one of two standard patents for the same invention and the applications were filed by the same person and have the same deemed date of filing, or a patent the application for which is filed on or after 19 December 2019, if it is one of two patents that are granted for the same invention made by the same inventor and have the same material date.
