Whitney Cotton Gin, Courtroom Model, 1800
In 1794, Eli Whitney patented a mechanical cotton gin, hoping to make processing cotton easier. Many contemporary observers believed that labor intensive crops like cotton were economically unsustainable, however the increased productivity made cotton more economically viable for planters.
Whitney used this courtroom model in a series of lawsuits against those that he accused of infringing on his patent. While he won most of the court cases he did not profit from the invention.
