An action may be maintained in the High Court by an inventor against any person who, during the con-tinuance of any exclusive privileges granted by this Act, without the licence of the said inventor makes, uses, sells or puts in practice the said invention or counterfeits or imitates the same.

The High Court shall have power upon the ap-plication of any person who alleges that his interests have been prejudicially affected by the issue of a certificate of

Inventions registration, to declare that the exclusive privileges and rights conferred by such certificate of registration have not been acquired on any of the grounds upon which the grant might be revoked under the law for the time being in force in the territory in which the grant was originally made.

Such grounds shall be deemed to include the manufacture, use or sale of th~ invention in Brunei before the priority date applicable to the patent in the territory in which the grant was originally made, but not to include the manufacture, use or sale or the invention in Brunei by some person or persons after the priority date applicable to the patent in such territory and before the date of the issue of the certificate of registration under section 4(1) .
