the USPTO
It can talk about upholding whatever it wants, it has done nothing but undermine the very idea of patents since the beginning of the 20th century.
By never verifying prior art and letting the judicial system take care of issues, the USPTO is just a rubber stamp for multi-billion-dollar behemoths and serves no longer the ideal of the individual inventor getting recognized for an idea.
On top of that, the USPTo has long forgotten the idea that a patent could only be granted to an idea that was functionally described in full, thus, when the patent expired, others coulld pick up the idea and make use of it. Today, patents are granted on simple ideas (round corners, anyone?), and their functionality is no longer a subject of examination.
