> How is patenting combination of spices going to increase innovation?

I'm sorry, but you seem to have jumped from "patents" to "patenting combinations of spices" here. I don't think that you did this intentionally, but you replaced the topic in between; first, you formulate your thesis as "we should abolishing patents", and later, you seem to be proving it, but you really only prove a different thesis, "we should abolish patenting combination of spices".

Don't you see the difference between these two?
