I mean I understand that something do seem and probably are trivial; but this almost seems like attempt to get anything someone comes up with dismissed (or worse, forced to give away ) based upon the assumption of some previous technique.
Correct me if I'm wrong, but even prior art evolves if someone dedicates time and energy to find a better way of doing something. And giving away one's time and effort for the "betterment of society" is nice and all, but it doesn't put food on the table for very long. At worse, it turns on into a worker drone, always trying to stay ahead of some never-ending path.
I guess as I see it, patents serve to allow one to get a breather and possibly enjoy some of the reward of the work they put in. The evolution of technology is inevitable, but going at a break-neck pace is unhealthy.
