Actually, I refuse the vocable “Intellectual property”, which let people think that you can own intellectual stuff the way you own a car. “Exploitation monopoly” is the real word for what they call IP.
Note that I don’t despise these monopolies as a whole (I’m the owner of a few of them myself). Actually, I believe part of the problem is to put things as remote as a trademark, a patent, a song, the recording of the song, etc… all together in the same bag. Having a clear separation of these very differents rights is, in my non-lawyer humble opinion, a real and interesting challenge for the lawyers of the 21st century.
