An essay in The Guardian discusses the difficulties around the concept of owning ideas, something I believe should not be possible in the first place.
"This is madness. Ideas aren't things. They're much more valuable than that. Intellectual property - treating some ideas as if they were in some circumstances things that can be owned and traded - is itself no more than an idea that can be copied, modified and improved. It is this process of freely copying them and changing them that has given us the world of material abundance in which we live. If our ideas of intellectual property are wrong, we must change them, improve them and return them to their original purpose. When intellectual property rules diminish the supply of new ideas, they steal from all of us."
