Patents

An invention is patentable if it is new, involves an inventive step and is industrially applicable.

An invention is new if it is not anticipated by prior art.

Prior art shall consist of everything disclosed to the public:

(a) anywhere in the world, by publication in tangible form; or
(b) in Tonga, by oral disclosure, by use or in any other way, prior to the filing, or where applicable, the priority date, of the application claiming the invention.

An invention shall be considered as involving an inventive step if, having regard to the prior art relevant to the application claiming the invention, it would not have been obvious to a person having ordinary skill in the art.
