abandoned property

n. property left behind (often by a tenant) intentionally and permanently when it appears that the former owner (or tenant) does not intend to come back, pick it up, or use it. Examples may include possessions left in a house after the tenant has moved out or autos left beside a road for a long period of time, to patent rights of an inventor who does not apply for a patent and lets others use his invention without protest. One may have abandoned the property of contract rights by not doing what is required by the contract. However, an easement and other land rights are not abandoned property just because of non-use. (See: abandon, abandonment)
