Most other crimes require intent, patent infringement does not. This is the problem I've always had with patents, but I've never been able to articulate it before.
Huh? Patent infringment consists of using some technique without the permission of the owner.
There's intent all over that.
Are you suggesting that folks are using techniques without the intent to use said techniques? Or that they aren't intending to use them without the permission of the owner? (Yes, you can argue that they didn't know that they needed permission but that doesn't change the fact that they intended to use them without permission.)
