See the great Jeffrey Tucker on why intellectual "property" -- copyrights, patents, trademarks, etc. -- harm innovation, benefit big corporations and have no place in a free society.
Anti-market and anti-competitive patents, contrary to state propaganda, only harm and clog innovation. According to a study done by the Research and Development magazine, between 1977-2004, "Nine in 10 of the innovations were never patented. They were just created and marketed, and changed the world. In other words, it’s the market, not the bureaucracy, that innovates."
