Clean room design (also known as the Chinese wall technique) is the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights and trade secrets associated with the original design. Clean room design is useful as a defense against copyright and trade secret infringement because it relies on independent invention. However, because independent invention is not a defense against patents, clean room designs typically cannot be used to circumvent patent restrictions.
The term implies that the design team works in an environment that is "clean" or demonstrably uncontaminated by any knowledge of the proprietary techniques used by the competitor.
Typically, a clean room design is done by having someone examine the system to be reimplemented and having this person write a specification. This specification is then reviewed by a lawyer to ensure that no copyrighted material is included. The specification is then implemented by a team with no connection to the original examiners.
Famous quotes containing the words clean, room and/or design:
“Continued traveling is far from productive. It begins with wearing away the soles of the shoes, and making the feet sore, and ere long it will wear a man clean up, after making his heart sore into the bargain. I have observed that the afterlife of those who have traveled much is very pathetic.”
—Henry David Thoreau (1817–1862)
“Fine art, that exists for itself alone, is art in a final state of impotence. If nobody, including the artist, acknowledges art as a means of knowing the world, then art is relegated to a kind of rumpus room of the mind and the irresponsibility of the artist and the irrelevance of art to actual living becomes part and parcel of the practice of art.”
—Angela Carter (1940–1992)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
