State of the art
[3] The earliest use of the term "state of the art" documented by the Oxford English Dictionary dates back to 1910, from an engineering manual by Henry Harrison Suplee (1856 – after 1943), an engineering graduate (University of Pennsylvania, 1876), titled The Gas Turbine: Progress in the Design and Construction of Turbines Operated by Gases of Combustion.[6] In this relation it has been quoted by the author that "although eighteenth-century writers did not use the term, there was indeed in existence a collection of scientific and engineering knowledge and expertise that can be identified as the state of the art for that time".[13] For example, "[u]nder German law, the producer can also raise the state-of-the-art defense: general tort law does not hold him liable if he could not know or discover the defect for lack of fault, and the Product Liability Statute expressly provides for this defense".Pursuant to this article: The state-of-the-art defense allows a defendant to be absolved of liability if he can prove that the state of technical and scientific knowledge, at the time when he put the product into circulation, was not such as to enable the existence of the defect to be discovered.As an industry magazine explained in 1984: Remote control rear view mirrors, disc brakes, automatic slack adjusters for drum brakes and sealed lighting systems are just a few examples of products that have advanced the state of the art.
