If the USPTO grants 12,345 new patents for toilet paper in various "innovative" roll width, and sheet shapes, and ply counts - that's a massive boost for their metrics -
especially their patent filing fee revenue.
(And these days - it might get their higher-up decision makers invited to some extremely nice parties, aboard the yachts of leading patent lawyers.)
Vs. where in their chain of command would anyone give a crap about the economic damage?
