Re: Gotta love Apple.
What do you mean by a model? Is a computer model/mathematic proof sufficient? After-all why should Mr Smith loose out because he can't afford to manufacture his new jet engine? Without a patent he can't safely go and ask someone else with the skills and equipment to manufacture it as they could just steal the idea and will have the resources to make it quicker.
I totally agree though that the system is broken, mathematical techniques and processes shouldn't be patentable (covering most of software - that can be copyrighted), the tests for innovative, technical effect and non-obvious to someone skilled in the art should actually be enforced. Taking X and shoving it on the internet or on a mobile phone is not generally innovative or non-obvious. Thinks like bouncing menus don't have technical effects and are just processes/mathematical techniques anyway.
