I think the best way to neutralize bogus patent claims would be to sue the patent office, and the involved examiners themselves, once a patent is found to be invalid (it shouldn’t have been granted in the first place).
Why? Because it shouldn’t be someone else’s burden (time, cost) to have to clean up the mess they created (not to mention the waste in public money with court proceedings).
But, as usual, government employees/agencies have “sovereign immunity”, which means they can get away with doing a bad job any other type of private employee would get fired for, without repercussions.
