>>1410772>as that would create a monopolyKind of a nitpick, but patents and copyrights and trademarks are defined as being a monopoly, monopolies are common, and they're usually not a problem. The reasoning behind patents is that the infringing party (and potentially even society-as-a-whole) may well be disadvantaged by the government enforcing a monopoly against them, but this is outweighed by the greater goods of the patent having to be published and eventually lapsing, and the promotion of more inventions in the first place.
This is why we have "antitrust" laws and not "anti-monopoly" laws: the problem is the market failure, not the monopoly per-se.
