Patent family

A patent family is a set of patents or patent applications in various countries in relation to a single invention, for example when a first application in a country – the priority application – is extended to other countries. In other words, a patent family is "the same invention disclosed by a common inventor(s) and patented in more than one country." Patent families can be regarded as a "fortuitous by-product of the concept of priorities for patent applications".
