An invention is considered new if it is not part of the state of the art. By the state of the art it is understood essentially all that, prior to the priority date (the most frequently reported invention) was made available in any way to the public.

Disclosed anywhere in the world information about the essence of the invention – in writing, orally, through exposure or use – is part of the state of the art. It is very important to maintain the mystery of the invention before filing. The presentation at the Scientific conference, publication in the journal, Disclosure at the exhibition or in the company catalogue causes the invention to lose the novelty feature, and thus loses its patentability.
