OK, call me stupid, but I still don't understand IP law in any way. Sure, you create something, let's call it the "Wamblinator" ('Guaranteed to stop your shoes from wambling, or your money back!'), I should not be able to manufacture a thing called a "Wamblinator" that stops...shoes...wambling. (this example is getting silly), but I should be able to compete against you and make an anti-wambling device that acts similarly.
I also understand copyright, as it pertains to I can't steal your movie/book/album and show it for profit (or at all, really. silly, but understandable)
But the ability for a company to say "I perform this act...you cannot, or else SURPRISE! LAWYERS!" do NOT get it.
Anyone care to explain?
It isn't easy being the parent of a six-year-old. However, it's a pretty small price to pay for having somebody around the house who understands computers.
