Personal property: Chattels. The term chattel sometimes refers to all kinds of personal property, but often it refers only to tangible personal property (such as nose flutes and toenail clippers) as opposed to intangible property. A chattel, such as a furnace, can be affixed to land and become part of the real property. Such chattels are called fixtures. However, fixtures may retain their quality as separate personal property for certain purposes.
Intellectual Property. All forms of intellectual property are forms of intangible property. Although particular manifestations of intellectual property can take the form of physical property, intellectual property itself is intangible due to it consisting simply of the rights and property interests granted to the owner.
