Property can and does refer to rights over both tangible and intangible assets. It simply refers to ownership. Trademarks, brand identity and trade secrets are property. Some kinds of license can be property, and bought or sold. Shares in companies, or bonds are property. You may not like it, but that's a separate question.

What's usually happening here is that property is being misinterpreted as meaning something like object, but it just refers to a right of ownership which can be of objects.
