 There's a myth out there that patents are only available for things that are complicated. People imagine inventors to be like that professor in the movie Back to the Future, and they expect to have like a flux capacitor before you go and see a patent attorney. Nothing can be further from the truth. Your idea does not have to be complex, doesn't have to be complicated in order to be patented. It only needs to be new, useful and not obvious. Sometimes it's the simplest of ideas that change the world for the better.
