Homework 1: Finding a Patent
Patent 4781139: One man manual boat hull cleaning device
Date issued: August 18, 1986
- The idea behind this patent was to create a device which could clean the bottom of a boat hull without necessitating lifting the boat out of the water or diving underneath while it is still in the water. The device consists of a long handle, capable of being held and manipulated by a person. At the end of the handle is a section made of a different material, with a length long enough to cover the surface of a boat hull from the water to the bottom of the hull. There is a scrubbing material attached to one side of this section, meant to go against the boat to achieve a cleaning affect. In order to form to the contours of the boat, the main material of this section is buoyant, so that it bends and sticks to the curvature of the boat.
Homework 2: Non-Obviousness, with Regards to 3 Cases
The Citations
There are 4 citations in my patent:

[http://www.google.com/patents/about?id=rN1oAAAAEBAJ "Patent 3010420: Buoyant boat bottom brush"

[http://www.google.com/patents/about?id=nwI4AAAAEBAJ "Patent 4648344:Boat hull cleaning device"
Three of the citations are patents held by other people, while the fourth citation is actually held by the same man who holds my chosen patent, and was only issued a year prior to my chosen patent. The first citation is a system of wires which go underneath the boat while it is in the water, to which a brush is attached on either side. They have inflatable areas, allowing them to be filled so that they are buoyant, and therefore rest against the boat hull while underwater. By moving the cables, one brush moves up the boat hull, while the other moves down, and reversing the motion reverses the directions, allowing for a scrubbing motion. The brushes are not large, so a significant movement up and down is necessary to reach the entire hull.
