“While there is a close relationship between intangible property and the tangible objects in which they are embodied, intellectual property rights are distinct and separate from property rights in tangible goods. For example, when a person posts a letter to someone, the personal property in the ink and parchment is transferred to the recipient…. [T]he sender (as author) retains intellectual property rights in the letter.” Lionel Bently & Brad Sherman, Intellectual Property Law 1–2 (2001).
