I am asking in all seriousness, what about this venture seems moral? This screams sleazy personal injury lawyer to me that wants to sue for car collisions where the paint didn't even chip.
As I said, he is not doing anything illegal, he is paying his staff, and he is only going after big companies.
I can understand the patent system harming small companies is bad, and I understand there should be no patents on simple ideas, but going after big companies is not as bad.
