Imagine what books or movies would look like if they used the same patent system as software.
Imagine Herman Melville patenting the concepts, themes and metaphors of „Moby Dick” or Cervantes patenting those in „Don Quixote.”
Then imagine that neither author even bothers to write his book and is just patenting his ideas to make money off writers who actually have the drive to do the writing.
This might seem absurd, but it’s exactly how software patents work. In fact, one could make the argument that it’s more beneficial to make money off a patented idea than it is to put that idea into action by coding the software.
