The jurisdiction of the general public. It refers to intellectual property that has either been voluntarily placed in the public domain by its author or that has passed its copyright, trademark or patent expiration date. However, rights in one country do not necessarily apply to another. International property rights is a complicated subject, as each country has its own statutes.
Certain property is automatically in the public domain, such as non-classified publications of the U.S government. This is not the case in Canada and other countries, although certain material is made publicly available. See public domain software
