[pp.int.general] map of intellectual property rights in lund

[Richard Stallman]

    I think this mostly covers the concept of both copyright and patents.
    Trademarks are a little harder to lump in (and for the most part I don't
    disagree with the idea of trademarks anyway)

That's the point -- these laws are so different that it's misguided
and harmful to generaliza about them.  For more explanation of this,
see http://www.gnu.org/philosophy/not-ipr.html.
