Ferag AG v Muller Martini Ltd

Ferag AG v Muller Martini Ltd

The Court of Appeal held that, on a proper purposive construction, claim 1 of Ferag's patent was infringed by the NewsTrim machine. The association between the knife part and the product did not require physical contact until cutting, and the process carried out by NewsTrim fell within the claim. The court further held that claim 1 was valid, as Stobb did not disclose a two-knife system and the modifications required to make it so were not obvious. Rösner did not anticipate claim 1 as the required movement past a fixed knife part was not disclosed.
