knuckles producing a left turn while the vehicle is moving in a forward direction. A turn
to the right is accomplished by the steering components moving in the opposite
direction as shown in Figure 7. Liebert teaches (column 7, lines 40-44) that "[t]he use
of a spring 41 and 42a 41a and 42a in each steering cable 41 and 42 was implemented
to absorb shock in the event one of the front wheels hit a hole or an obstacle and
thereby lessen the potential for injury to the operator."
Ascertainment of Differences
After the scope and content of the prior art are determined, the differences
between the prior art and the claims at issue are to be ascertained. Graham v. John
Deere Co., 383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966).
Based on our analysis and review of Suto and claim 1, it is our opinion that one
difference is the limitation that "the running toy further comprises a shock absorber for
absorbing a shock transmitted through the steering rods and wherein the shock
absorber is a coil spring member formed by winding up a part of the steering rods in a
coil form."
