Article summary

IP analysis: The Court of Appeal has upheld the decision of the Intellectual Property Enterprise Court (IPEC) in Penhallurick v MD5 Ltd which rejected a claim for copyright infringement in respect of a number of literary works consisting of computer software. The appeal largely focused on whether there had been assignment of copyright by Mr Penhallurick to MD5 Ltd by virtue of a contested ‘November 2008 Agreement’. Lord Justice Arnold also commented on the types of cases suitable for the IPEC, and how parties should deal with cases which evolve into something considerably more complex than originally envisaged.
