Optis Cellular Technology LLC & Ors v Apple Retail UK Limited & Ors

Optis Cellular Technology LLC & Ors v Apple Retail UK Limited & Ors

The Court of Appeal held that the claims are to devices capable of operating with the relevant code multiplexing structure (CMS), not limited to actual use. Apple devices are adapted to operate with the CMS and thus infringe. The Nokia prior art does not anticipate the claims because the CMS as a whole must satisfy the claim, not just in limited circumstances. The 810 patent requires association with the CCE, not merely the downlink channel number. The claims are not obvious.

Procedural Posture

Civil Appeal / Appeal From High Court (patents Court) to Court of Appeal

Legal Issues

  1. 1 Proper construction of 'adapted' in patent claims for mobile devices
  2. 2 Whether Apple devices infringe Optis' patents under UK law despite feature not being used in UK networks
  3. 3 Whether prior art (Nokia) anticipates the claims

Ratio Decidendi

The Court of Appeal held that the claims are to devices capable of operating with the relevant code multiplexing structure (CMS), not limited to actual use. Apple devices are adapted to operate with the CMS and thus infringe. The Nokia prior art does not anticipate the claims because the CMS as a whole must satisfy the claim, not just in limited circumstances. The 810 patent requires association with the CCE, not merely the downlink channel number. The claims are not obvious.
