  • June 28, 2017 — Some of us in the practice remember the “cited prior art” of Sakraida v. Ag Pro. The U.S. Supreme Court invalidated a patent on a system to flush out barns for cows, U.S. Patent 3,223,070 of 1965. Notoriously, the first-referenced prior art in the Court’s obviousness analysis was “among the labors of Hercules.” 423 U.S. 273 at 275 n. 1 (1976).
