This guide brings together some of the best places to find existing patents with a number of useful resources for learning more about patents and the process of obtaining a patent on a new invention. A patent is a right granted for any device, substance, method or process which is new, inventive and useful. It is legally enforceable and gives the owner the exclusive right to commercially exploit the invention for the life of the patent. (Source: IP Australia)
