House of Lords

Copyright: infringement and defences

Facts

LB (Plastics) made a knock down drawer system, designed from drawings made by its designer. Swish Products produced a similar drawer system, which was designed to be compatible with LB's drawers, by studying LB's drawers. Swish did not see LB's drawings. LB sued for infringement of copyright in its drawings.

Legal principle

The House of Lords held that Swish had infringed. Copyright in a drawing can be infringed by making a three dimensional object which reproduces the drawing, even if the copying is indirect, through a product made from the drawing. Lord Wilberforce said that the question was whether Swish had copied a substantial part of LB's design, and that it had copied the features of the drawers that were essential to their design. The ability to rely on copyright in design drawings to protect functional products was later limited by the Copyright, Designs and Patents Act 1988.
