Icescape Ltd v Ice-World International BV & Ors

Icescape Ltd v Ice-World International BV & Ors

The patent was not entitled to priority as features A, D, and E were not disclosed in the priority document; the patent was therefore invalid. Although the Icescape system would have infringed the patent under the Actavis approach to equivalents, the patent's invalidity precluded relief. Ice-World failed to prove lack of knowledge or suspicion of invalidity, so the defence to groundless threats was not established.

Ratio Decidendi

The patent was not entitled to priority as features A, D, and E were not disclosed in the priority document; the patent was therefore invalid. Although the Icescape system would have infringed the patent under the Actavis approach to equivalents, the patent's invalidity precluded relief. Ice-World failed to prove lack of knowledge or suspicion of invalidity, so the defence to groundless threats was not established.
