I don't know what's so good about it... in a nutshell congress is attempting to limit damages, narrow it's scope, and allow for challenges post granting of a patent for it's lifetime. This favors those who wish to steal others inventions, and those who wish to limit their liability when licensing others. Big business is the winner here, make no mistake about it. This is stifle invention and upset our economy dependent on innovation. What incentive is there when others will be able to steal your invention and pay you paltry sums for their use.
