A patent is a legal document that protects new and original inventions, substances, products, methods, processes and devices. It gives the patent owner exclusive rights to commercially exploit their invention for the lifetime of the patent.

Each country controls its own patent application process. IP Australia is responsible for processing and granting Australian patents.
