"If you own a software patent, you should feel bad." You might think its "just for defense" and have the best of intentions, but like landmines and toxic waste, the patent will almost certainly outlive your use for it and wind up in hands other than your own.

So there it is: Patents are like the toxic waste of innovation. You promise yourself to keep them safely contained, but its hard to do in the real world and once they spill, they contaminate everything around them, making the ground uninhabitable for 20 odd years.

Feel bad.
