Patent purity is a legal property of an object (device, product, substance, technology, etc.), which characterizes the possibility of its use without violating the rights to valid patents of other persons in the territory of a particular country or region.
The fact that the object has patent purity means that it can be freely manufactured, stored, sold, advertised (for products) or sold (for a method) within a certain territory without the risk of violating other people's patent rights.
