Nokia v IPCom [2012] EWHC 225

Case Summary  |  Judgment  |  20 February 2012

 

As part of its long-running dispute with IPCom, Nokia sought revocation of a patent relating to handover of mobile phones between base stations. IPCom sought to amend the patent to one of a number of claim sets; Nokia sought to invalidate the broadest claim set and sought declarations of non-essentiality of all the claim sets to various mobile telephony standards. Floyd J held that the broad claims were invalid and permitted amendment only to a narrow claim set of no commercial significance. He also granted the declarations of non-essentiality. Michael Tappin QC and Mark Chacksfield acted for Nokia.
