Legal Question in Business Law in California

Re: patent

It's the same cost for the poverty stricken as anyone else - expensive. You'll have to employ patent counsel to research and prepare your applications at many thousands of dollars. Another option, but one filled with risk, is to take it to an inventors assistance company who will do it for a share of the royalties. Don't ask me for names of legitimate ones; I'm told there may be a few among the many frauds and scam artists. Do your research.
