The original idea of patent was perhaps like that - these days patents are used by large corporations to prevent anyone else from even entering their markets.
Excuse me but what's wrong with that?
That's how market's work and patent and royalty .
If someone Discovers /develops something , they have full copyright and patent on it and if someone decides to use it ! They pay for it .
Let's consider it as with your name , You have complete Copyright over your name and avatar. What if someone makes a same username (with a lil difference and same is not allowed) and gets same avatar( i know not allowed for now) BUT is a totally different guy and by chance chose the same avatar but have same name (I don't know if it is your real photo , we are just supposing it here) . People will instantly tag him as Fake even though he did nothing wrong , probably the poor guy doesn't even know what happened to him.
Same is in the case of Signature Campaigns , we lend our copyrighted names and Identity to them to earn some money.
The idea of Patent/Copyright is totally solid in my opinion and should stay.
