US copyright law is already terrible. Software patents can be even worse. Have ever heard of patent trolls?I hope we're not so stupid as to implement something like this here in the US but I don't have high hopes. Just look at all the stupidity / hysteria around "net neutrality". Too many people in positions of power eager to abuse the potential of the internet.
True story: a number of years ago (iirc, it was in the go-go 90's), somebody copied several hundred lines of copyleft (see https://www.gnu.org/licenses/copyleft.en.html) code, filed for a patent, on code he stole, which was granted, and proceeded to sue the author of the code for patent violations.
Charlie Stross has predicted the government will soon outsource copyright enforcement to corporate entities like the RIAA which will sub it out to organized crime. Seems likely to me.
