LB (Plastics) Ltd. v. Swish Products Ltd.,[1][2] is a 1979 decision of the House of Lords as to whether a physical object is an infringing copy of a drawing depicting the object.
The House of Lords held that it is, at least when an ordinary person could recognize that physical object was that which the drawing depicted.
The House of Lords later reaffirmed the principle stated in this case in British Leyland Motor Corp. v. Armstrong Patents Co.,[3][4] saying that it must be regarded as "settled law".
The position under United States federal copyright law is diametrically opposite.
