Novartis (AG) v Ivax Pharmaceuticals UK Ltd

Novartis (AG) v Ivax Pharmaceuticals UK Ltd

Equoral does not infringe the patent because the majority of the active ingredient is not carried by microemulsion-sized particles, which is the core teaching and purpose of the patent. Additionally, Equoral does not contain a lipophilic phase as required by the claim, as its candidate component is amphiphilic and does not meet the patent's requirements.
