A Patent is a title recognising the exclusive right to make use of a patented invention, preventing others from manufacturing, selling or using it without the patent holder's consent. In exchange, the Patent reveals the details of the invention to the general public.
The right granted by a Patent is not so much the right to manufacture, offer on the market or use the object of the Patent, rights that the title holder always has and can exercise, but especially and uniquely, "the right to exclude others" from manufacturing, using or introducing the patented product or procedure in the course of commercial activity.
A Patent can refer to a new process, device, product or the improvement or advancement of any of these. The duration of a Patent is twenty years starting from the date of the presentation of the application. In order to maintain the Patent in effect, yearly fees must be paid once it has been granted.
