"A really interesting thing about this judgement is found near the end, in para 57. There, the judge states that "this appeal is not concerned with an idea or an invention, but with a design".  But if RCDs are ineffectual in protecting highly original designs, then how can designers protect original ideas (other than by taking out lots of RCDs to cover possible variants of the design)?  Design patents do not exist in the UK / EU.  Technology patents are not applicable.  Are trademarks or copyrights any good?  (sorry about the bold, don't know how to remove it)"
