This is a terrible idea. If you read the AMA from the patent examiner on reddit, he described that an shitty patent passes because, even though its obvious to the examiner, they can't mark it as bad unless there is prior art that they can find. They can't conduct exhaustive searches for these prior arts and if they can't find prior art then they have to validate the patent.
We need to change the system from the ground up. Not start to make liable some poor fella who happens to work at the USPTO who would have no idea that a legitimate patent would cause a multi-million dollar case.
