Even the phrase "intellectual property" is highly tendentious. It implies property right where there are none. What you get from the patent office is a temporary government granted monopoly.
Often, as with, for example, spectrum, the people holding the license tend to view the object, and not the government granted license, as their perpetual property.
Depends upon how you look at it. I find the idea of property rights a bit funny because every physical thing you can own exists because in the past someone murdered the fuck out of people to own what it's made from.
In that regard, intellectual property is the only property not built on human suffering.
