The Case
On the facts of the instant case, it had not been established that the full extent of the patent claim in the instant case was the inevitable result of other features of the patent claim being present in the prior art, and accordingly the patent was valid. Furthermore, the judge had been wrong to imply a limitation into the claim by importing a word into the claim, and as a result the patent was also infringed by the defendants' apparatus.
