"I do not accept that the use of any of CTI’s Registered Trade Marks in Green Energy’s metatags would constitute a trade mark infringement for the purposes of s 120(1). Metatags are invisible to the ordinary internet user, although their use will direct the user to (amongst other websites) Green Energy’s website. Once at the Green Energy website, then, in the ordinary course, the internet user will be made aware that the website is concerned with Green Energy’s services. It cannot, therefore, be said that the use in a metatag of CTI’s Registered Trade Marks is a use that indicates the origin of Green Energy’s services. Thus, metatag use is not use as a trade mark"
