Homework 1 - Due Monday, January 24
- Backboard Basketball Retriever
- Patent 4,786,371
- Issued November 22, 1988
This invention basketball return system easily mounted to a backboard and which can be adapted to return the ball to a specific location. It is composed of a net-carrying frame which is positioned under the backboard/hoop that will catch the ball and forward it to the player after he or she shoots. There are a number of basketball return systems dating from June 17, 1930 which can be viewed as prior art. To distinguish this particular system from prior art, the invention seeks to overcome some of the problems exhibited by older systems. This invention attempts to distinguish itself from prior art by making the apparatus easily retractable to facilitate storage, return the ball at a height so that the player doesn't need to bend over to pick the ball up (instead, the player acts as though he is receiving a pass), be able to extend or shorten the length of the return system, and mounts to the backboard.
Homework 2 - Due Friday, January 28
Backboard Basketball Retriever(4786371) cites JFree Throw Basketball Return(3917263), another basketball return system that differs in several ways. This particular basketball return system is implemented by use of an inverted truncated conical frame that is placed underneath the basketball rim. The opening initially leads to a chute perpendicular to the ground which eventually levels out to be parallel to the ground. The frame sits upon a set of wheels for easy mobility of the device. Beneath the chute is a leg brace and a rack for storing spare basketballs. The entire frame/chute acts as a guide for the basketball which is returned to the player at the free throw line. Additionally, the backboard basketball retriever makes reference to Ball Recovery System (4291885). Among other things, this patent makes use of a net attached to the backboard at one end and to a handicapped player at the other end to return the ball directly to the shooter.
Under Hotchkiss v. Greenwood, 52 U.S. 11 (1850), an improvement which consists solely of a change in material in order to improve functionality cannot be the subject of a patent. Hotchkiss showed that if no other skill or ingenuity was needed beyond that which an ordinary mechanic acquainted with the business might have, then the patent is void.
