Designers Guild Ltd v Russell Williams (Textiles) Ltd (trading as Washington DC)

Copyright infringement depends on whether features copied from an original work amount, cumulatively and qualitatively, to the whole or a substantial part of that work. Substantiality is assessed by the importance of what was taken to the claimant’s work, not by its importance to, or the overall appearance of, the defendant’s work.

Ideas embodied in an artistic work may be protected where their expression represents sufficient original skill and labour. Commonplace or highly abstract ideas ordinarily do not constitute a substantial part. Once the scope of copying has been fixed, the court must not dissect the copied features piecemeal or use other differences to reopen that finding. An appellate court should not overturn the trial judge’s evaluative conclusion on substantiality unless there was an error of principle.

Designers Guild Ltd v Russell Williams (Textiles) Ltd (trading as Washington DC) concerned copyright in the artwork for the Ixia fabric design. The deputy judge held that the respondent had copied that design when creating its Marguerite design and that the copying reproduced a substantial part of the copyright work. The first-instance decision was reported at [1998] FSR 803.

The respondent did not challenge the finding of copying in the Court of Appeal. It argued only that the copied material was not a substantial part. The Court of Appeal accepted that argument after visually comparing the designs and analysing their individual features.

The central questions before the House were how substantiality should be assessed under section 16(3) of the Copyright Act 1988, how the distinction between ideas and expression applied to an artistic work, and when an appellate court could reverse the trial judge’s evaluation.

1. Appeal allowed unanimously. The House restored the deputy judge’s order. Lord Bingham gave reasons adopted by the other Law Lords. Lord Hoffmann, Lord Millett and Lord Scott supplied additional analysis.

2. Per Lord Bingham, Lord Hoffmann and Lord Millett, substantiality under section 16(3) of the Copyright Act 1988 asks whether the features found to have been copied formed a substantial part of the claimant’s work. The inquiry is qualitative. It concerns the importance of the copied material to the copyright work, not the resemblance between the works as wholes or the importance of that material within the defendant’s work.

3. Per Lord Hoffmann, copied features must be assessed cumulatively. The Court of Appeal erred by dissecting the design into stripes, flowers, brushwork and resist effect, and by discounting each feature separately. Once it was accepted that the identified visual effects had been copied, differences in the result achieved by the defendant could not answer whether those effects together represented a substantial part of the original work.

4. Per Lord Hoffmann, the distinction between ideas and expression must be handled with care. There is no copyright in an unexpressed idea, in an idea unrelated to the literary, dramatic, musical or artistic nature of the work, or in an artistic idea too commonplace or unoriginal to represent a substantial part. Original artistic choices may be protected cumulatively. A substantial part can consist of a combination of features abstracted from the work rather than a discrete segment.

5. Per Lord Millett, visual comparison is relevant initially to identifying copied features and deciding whether similarities, together with access, justify an inference of copying. Once copying has been established, substantiality depends on the quality and importance of what was taken from the claimant’s work. Differences elsewhere in the defendant’s work, including differences affecting its overall appearance, do not prevent infringement.

6. Per Lord Scott, the case involved altered copying. In such a case the useful inquiry is whether the defendant incorporated a substantial part of the independent skill and labour contributed by the original author. He considered the extensive similarities determinative of both copying and substantiality on these facts. The other speeches did not treat his suggested distinction between altered copying and copying a discrete part as necessary to the result.

7. Per Lord Bingham, Lord Hoffmann, Lord Millett and Lord Scott, substantiality required application of a legal standard to an overall factual evaluation. The trial judge had made no error of principle. The Court of Appeal therefore should not have substituted its own impression. The appellants were awarded their costs in the House and the Court of Appeal.

1. House of Lords: The appeal was allowed unanimously. The Court of Appeal’s decision was reversed and the deputy judge’s order was restored.

2. Court of Appeal: The respondent did not challenge the finding of copying. The court allowed its appeal on the ground that the copied material did not constitute a substantial part of the copyright work.

3. High Court, Chancery Division: A deputy judge held that the Marguerite design had been copied from the Ixia design and reproduced a substantial part of it, and gave judgment for the copyright owner: [1998] FSR 803.
