It's all crap, of course. Patents are a brilliant invention whereby innovation can be rewarded. In order to have an invention or innovation protected by a patent, the plans must be lodged with the patenting authorities; those plans are then available for scrutiny by others. Anyone can get round a patent by further improving upon an invention. Patents are also not a long term restriction, they tend to decay after about 10 - 15 years. The patent for Prozac just ran out, after around 10 years. A patent is not a licence to print money - the only way to keep making money on an invention is to keep improving upon it. There is a myth (perpetuated by the anti-GE crowd) that seeds can be patented - it's totally false, of course!
