Why look for patents?
A patent is an exclusive right granted for an invention, which is a product or a process that provides a new way of doing something, or offers a new technical solution to a problem (WIPO).
Patents are a broad source of technical information and encourage innovation. Many companies do not disclose their products in any other form.
