It's been my experience that 98% (or so) of patents are issued for non-novel ideals. It's merely a race to put a stake in the ground for future litigation (and mitigation of future litigation).
What this has done is prevented or slowed firms, small and large, from innovating due to the threat of litigation. How much further ahead could we all be, technologically speaking, if ideas could be implemented without this black cloud hanging over people's heads?
Instead we see the same regurgitated products, decade after decade, with with only incremental, and often unneeded or unwanted 'upgrades'.
