Procedural Posture

Patent Infringement and Revocation / First Instance Judgment (trial A)

Legal Issues

  1. 1 Is EP (UK) 1 230 818 valid?
  2. 2 Is EP (UK) 1 230 818 essential to GSM standards?
  3. 3 Has Apple infringed the patent?

Ratio Decidendi

EP (UK) 1 230 818 is valid and essential to GSM standards because the conversion of UMTS measurements to GSM format and comparability is disclosed, not obvious, and sufficiently enabled. Apple’s devices infringe the patent by implementing the relevant standards. Prior art does not render the claims obvious or insufficient. Conversion is not arbitrary and covers both comparability and formatting.

Court Disposition

Claim for infringement succeeds; counterclaim for revocation fails.

Orders

  • EP (UK) 1 230 818 found valid and essential to GSM standards.
  • Apple found to infringe EP (UK) 1 230 818.
