• Technetix v Teleste. Acting for Teleste in successfully defending them against a claim of patent infringement brought in the IPEC. The case was widely reported, as it was the first time that the English courts had considered the existence of a “Formstein defence”. The court held that the asserted patent was invalid and also held that whilst the alleged infringement would have fallen within the scope of the claims under the doctrine of equivalents, Teleste would have been entitled to a Formstein defence, if such a defence exists in English law.
