7 April, 2016

The Supreme Court of the United Kingdom recently handed down its decision in the case of PMS International Group Plc (Respondent) v Magmatic Limited (Appellant), otherwise known as the Trunki case.


By way of brief background, Magmatic (the designer of the Trunki suitcase) had launched infringement proceedings against PMS International in respect of a European Registered Community Design (RCD). Magmatic had been successful in the High Court, which found that the RCD was infringed by PMS International. The High Court decision was overturned in the Court of Appeal. The Supreme Court effectively upheld the decision of the Court of Appeal, so the final word on the matter is a finding of no infringement.

One of the representations in Magmatic’s RCD is shown below, adjacent to one of PMS International’s products:

For a design to infringe an RCD, the design must not “produce on the informed user a different overall impression” than the RCD (Article 10(1) of the Regulation). Determining scope of protection afforded by an RCD is influenced at least in part by the prior art. As a very rough rule of thumb, where the differences between the RCD and the prior art are minor, the scope of the RCD is likely to be narrow. By contrast, where the differences are significant, the scope of the RCD is likely to be broader.

The designer of the Trunki had previously disclosed a children’s ride-on suitcase called the Rodeo which was relevant when determining the scope of protection afforded by the RCD.

Supreme Court Decision

By the time the case reached the Supreme Court, the issues to be decided were relatively narrow. The Supreme Court agreed with the Court of Appeal in finding that:

(a) the High Court had not given sufficient weight to the overall impression on the informed user being that of a horned-animal (by contrast with e.g. a ladybird);
(b) an absence of surface ornamentation in the RCD representations is a part of the design and therefore contributes to the overall impression on the informed user; and
(c) the two-tone representation of the RCD (whereby the strap and wheels are shown in a different tone from the body of the case) contributes to the overall impression on the informed user.

In short, therefore, since PMS International’s design was (a) not a horned-animal, (b) included surface ornamentation that contributed to the overall impression; and (c) did not have a two-tone contrast between, on the one hand, the wheels and strap, and, on the other hand, the body, the Supreme Court found no infringement.

Lessons for those seeking Registered Design protection

It seems likely that the significance of the “horned-animal” to the overall impression on the informed user would have been reduced in the event that the Rodeo disclosure had never been made. By disclosing the Rodeo before the filing of the RCD, Magmatic effectively reduced the scope of protection of the RCD.

The Supreme Court decision states that “it is right to bear in mind that an applicant for a design right is entitled, within very broad limits, to submit any images which he chooses”. The fact that the applicant chose to submit a computer aided design (CAD) drawing which shows the surfaces clearly and without ornamentation appears to have been influential in the Supreme Court’s view that the absence of ornamentation contributes to the overall impression.

If the design had been represented in the RCD by black on white line drawings showing only the overall shape of the design and with less emphasis on the surfaces, the scope of protection may not have been limited by the unornamented surfaces or the tonal contrast.

Lesson one: If you develop an early prototype design, keep in mind that if you disclose it then it may influence the scope of protection afforded by a later Registered Design to an improved design.

Lesson two: File a number of Registered Designs to include line drawings, CAD drawings and photographs of the product. Line drawings are likely to provide a broad scope, CAD drawings less broad, and photographs most narrow. In the event of a desire to take action for infringement, the rights holder can then make a choice about which RCD to rely upon dependent upon the facts of the case.

With this in mind, designers should note that it is possible to file a multiple RCD application, comprising more than one design. The cost of second and subsequent designs in the same application is less than half that of the first. Where an RCD application includes more than ten designs, the cost of the eleventh and subsequent design is even more heavily discounted.

The finding of no infringement in this case has prompted a wide range of responses from designers, intellectual property attorneys and other interested parties. Perhaps this is because the role of subjective analysis in determining infringement is arguably greater for registered designs than for other forms of intellectual property. Nevertheless, the decision provides designers with clear and broadly-applicable lessons for future design filing strategies which should help to avoid the same pitfalls in the future.
