There are laws about what happens to me if I break into your house and steal your property. I can therefore find you case precedent indicating that a TV is property because people have been charged with violating those laws when they steal a TV.

But I can't present to you the absence of such a thing. We have trademark, copyright, and patent law, but as far as I'm aware there's no crosstalk with things that talk about property, things like armed robbery.
