IPCOM GmbH & Co Kg v Vodafone Group Plc & ors

IPCOM GmbH & Co Kg v Vodafone Group Plc & ors

Vodafone infringed IPCOM's patent by operating access control in accordance with the LTE standard, as the claims were construed to cover such operation, including by equivalents. The Crown use defence did not apply because there was no written authorisation to do acts that necessarily infringed the patent. Vodafone's acts were not de minimis given the context and commercial significance. The patent claims as construed were not obvious over the prior art. The conditional amendments did not extend the protection conferred by the patent. The form of the essentiality declaration was within the judge's discretion.

Legal Issues

  1. 1 Whether Vodafone infringed IPCOM's patent by operating access control in LTE networks
  2. 2 Proper construction of the patent claims, including 'access right', 'privileged user class', and 'set up to send'
  3. 3 Whether the Crown use defence under section 55 Patents Act 1977 applied

Ratio Decidendi

Vodafone infringed IPCOM's patent by operating access control in accordance with the LTE standard, as the claims were construed to cover such operation, including by equivalents.

Vodafone's acts were not de minimis given the context and commercial significance. The patent claims as construed were not obvious over the prior art. The conditional amendments did not extend the protection conferred by the patent. The form of the essentiality declaration was within the judge's discretion.

Court Disposition

Vodafone's appeal dismissed; IPCOM's appeal on Crown use allowed; IPCOM's appeal on 'set up to send' dismissed.
