Patents are almost nothing. (...)
I partially disagree. Patents are very relevant... just ask the Samsung and Apple lawyers!
I have been battling with that for the last 2 weeks: I didn't invent anything, but I found a use for something that no one had thought before, and I adapted that idea, improving it A LOT. The new use is eligible for a patent, and there is nothing in the market like it. It has become a really "marketable" (is there such word?) product, and now I need an investor. All the investors I've seeked require that I have a patent, so I am applying for one (with is gonna leave me US$ 2,000 poorer).
