All of the companies you listed were started by American individuals with minimal budgets. So I ask you, why don't you go out and do the same?
If only you were right. The INTENT of patents is to allow an inventor to protect their inventions and to profit from their ideas. In truth, they are simply a legal right to a monopoly over an "invention" whether or not you are the "inventor" or just a patent holder or some entity that holds the rights to said "invention." Even the word "invention" is used VERY loosely with regards to patents in this day and age. Some "inventions" are nothing more than an idea with no tangible or actual invention in fact. (i.e. business methods, software, etc. they're even skirting alongside discoveries pretending they're "inventions" like genetic information, for example.). Oh what a f***ed up system it is. If ONLY it were used just to protect inventors and to promote inventions, instead of being used as a club to violently beat others over the head.
