*Kennametal Inc v Pramet Tools SRO and another

Patent – Infringement. The Patents Court considered a claim for infringement of a patent concerning milling cutting tools for high feed face milling. The court held that, on the evidence, two inserts made by the defendant company did not infringe the claimant company's patent. However, on the evidence, the defendant's counterclaim for obviousness would succeed, since the claimant's patent lacked inventive step in the light of the prior art.
