"7. ... Qualtex formed the intention to have manufactured and to sell a replica of the Henry cleaner. Qualtex concluded that, provided that they chose a design in which all relevant intellectual property rights (such as all the various forms of national and community, registered and unregistered design rights) had expired, they should be free to do so, provided that they did not use any Numatic trade mark such as the name Henry. In this they are absolutely right. There is no point in having design rights with expiry dates if traders are not free to market replica products thereafter. The only qualification to this is that they must not market a product in such a way as to lead to passing off".
