They Invented What? (No. 26)
U.S. Pat. No. 4,455,816: Pedal operated mower.
What is claimed as new is as follows:
1. A pedal operated mower assembly comprising a tricycle frame having a front wheel mounted in a fork, a central frame mounting a pedal sprocket and a wide fork frame at the rear supporting a reel-type mower assembly, the mower assembly having spaced support plates mounted on the wide fork frame, the support plates supporting a shaft having a rear sprocket about a midpoint of the shaft for chain engagement with the pedal sprocket, separate arrays of cutter blades spaced about the shaft on opposite sides of the rear sprocket respectively, said arrays of blades being mounted upon the shaft for rotation therewith and defining a gap therebetween in which is located the rear sprocket, a drive chain connecting the pedal sprocket and the rear sprocket, the drive chain being received in said gap, and a cutter member cooperating with the cutter blades for providing mowing of the grass.
2. The invention according to claim 1 wherein the support plates further support a roller shaft on which is mounted a roller positioned rearwardly of the cutter member.
3. The invention according to claim 1 wherein a protective shield is mounted on rod means above the cutter blades on the wide fork frame, the protective shield having a radius of curvature with its radius centered proximate the radius of the shaft mounting the cutter blades.
4. The invention according to claim 1 wherein the tricycle frame includes a wide seat being mounted on the tricycle frame, and handle bars are mounted by a goose neck means extending upwardly from the front wheel fork.
5. The invention according to claim 1 wherein the support plates for the mower assembly are pivotally mounted upon the tricycle frame and the support plates are rigidly spaced apart by a shaft for the roller, by the shaft for the rear sprocket and for mounting the cutter blade, and by a spacer rod.
KSR v. Teleflex: Notable Quotes from the Oral Arguments
Well, November 28th was certainly an interesting day at the Supreme Court (to those in the Patent Bar, at least).

Teleflex arguments leaves me pessimistic that the “TSM test” will escape this challenge unscathed.
Below are some quotes that I found of particular interest:
