Koninklijke Philips Electronics N.V. v Nintendo of Europe GmbH, London, UK, 20 June 2014, Case No.  EWHC 1959 (Pat)
This case concerned validity and infringement of three patents owned by Philips. The first patent claimed a means of controlling the movement of a virtual body in a computer-generated virtual environment; the other two patents covered electronic pointing devices designed to be held in the hand and used to control electrical apparatus. Nintendo denied infringing any of the patents and counterclaimed for invalidity. Philips made conditional applications to amend these last two patents but contended they were still valid as granted.
On the facts it was held that the first patent was invalid for obviousness over an earlier Nintendo gaming system. The other two patents were challenged a number of grounds, including added matter. The unamended patents were held to be invalid but the Court ruled that the patents in their amended form were valid: although the scope of the amended claims meant that they covered the use of “beacons” in contexts other than identification equipment, they did not disclose such an idea. There was therefore no added matter.
