The US Patent Office lost the proper idea of what constituted a patentable invention long ago. It's not supposed to be about what the goal is, but rather about how the goal is accomplished. If given the goal, any number of people in the involved industry could come up with the same solution within hours, it's not supposed to be patentable. Patents were supposed to be about inventing new technology to accomplish obvious goals, not thinking of new ways to use existing technology.
