The best place to learn anything is not Wikipedia. You can have that advice for free.
It's also very important use correct legal words to describe things, saying that copyright is for inventions and patents are for ideas and than diminishing the differences as being pointless legalities makes you look you have no clue what you are talking about.
I have no clue what you're talking about. I have never said the difference between a patent and copyright is pointless. I'm quite aware of exactly what the difference is. I'm not overly sure you are.
