Patent system created around a century before is already outdated. In today's world of Social communities and collaborative working it is very difficult to define the origin of an "Idea". It is true that intellectual property had created a capital investment revolution but at the same time it also create Grid Lock Economy. Michael Heller had identified this in his book very nicely. The IP system is mainly based on western and capital culture. The only main beneficiary for this system is capital not the individuals contributing to it. As new cultures will start taking strong position like Chinees and Indian, it will be difficult to hold this status quo for long time.
The benefits for the humanity will be huge if it is possible to deprecate IP system.
