Roger Rocket is a designer of paper cups at Paper America. During his free time, he likes to attend baseball games at Yankee Stadium. One day, while seated in the stands, he caught a fly ball. He took the baseball home and played catch with his friends Andy Cannon, Orlando Torpedo, and Mariano Missile. Unfortunately for Rocket, Cannon has a problem with accuracy. Cannon threw the ball over Rocket’s head and straight through a neighbor’s front window. The shattered glass ripped the lining off of the baseball. Instantly, Rocket conceived a more durable baseball with an exterior similar to that of a golf ball. Rocket worked for months on his invention in Missile’s garage. His new baseball was comprised of a titanium core, and a plastic shell having circular dimples and V‐shaped laces. Torpedo realized and told Rocket that Y‐shaped laces would enable baseball players to throw the ball faster. Cannon, an engineer in a radar gun laboratory, tested the velocity of the baseball with both V and Y‐shaped laces. To Cannon’s surprise, the baseball traveled 10 M.P.H. faster with the Y‐shaped laces. Rocket wanted patent protection for a baseball having a titanium core, and a plastic shell having circular dimples and Y‐shaped laces, so he approached Yogi Practitioner for assistance. Rocket has no obligation, contractual or otherwise, to assign his inventions to Paper America.
