They should have bothered 50 years ago, before the damage was done. Also, the US Supreme Court does not have the power to structurally modify the way the USPTO works and how patents are evaluated. It stands to reason that the rate of real invention should approach some kind of an asymptotic limit with time. In other words, real invention is far more difficult with time...because we have learned so much already. The example of the LED PWM control patents demonstrates this well. PWM control of, well, everything, had been known, applied and taught in schools for decades before these patents were ever penned. Anyone with an electrical engineering background who read these patent applications would kick the applicants out the door with a "Nice try! Get the hell out of here!". Not the USPTO. They took the money and granted several patents. And with that they caused damage to the industry. The only way further damage to innovation was prevented was when a mega corporation took these criminals out by paying them off. That's just terrible. Our patent system should not create such situations. The damage done to innovation is incalculable.
