McGhan Medical Uk Ltd v Nagor Ltd and Biosil Ltd: PatC 28 Feb 2001

The claimants had a patent for breast (and other) implants, the surface of which was claimed to be an improvement. They claimed infringement, and the defendant challenged the validity of the patent as lacking novelty, obviousness, and that description extended beyond the claim. The claim for infringement failed, as did the cross application to defeat the patent.
