While I agree that the current practice of IP landscaping does sometimes have the effect of stifling innovation I don't believe that the patent system should be completely abolished, just changed. The act of rewarding the first person to come up with something new encourages people to innovate, but patent applicants should be required to demonstrate how they would implement the idea described in the patent to prevent people from patenting concepts that they hadn't fleshed out. For example, GE shouldn't be able to patent the idea of building a wind turbine with a certain type of blade if they haven't already demonstrated a design that works.
