Nokia GmbH v IPCOM GmbH & Co KG

Nokia GmbH v IPCOM GmbH & Co KG

The Synch Patent is invalid for obviousness under the construction adopted by the trial judge, which was correct. The features of preprocessing and up-to-date frequency measurements are not limited as IPCom contended, and the lock-on synchronisation feature is obvious. The trial judge was right to refuse permission for post-trial amendment of the Access Rights Patent; procedural fairness and established principles preclude a second trial on validity after the patent has been found invalid. There was no error of principle or exceptional circumstance to justify departing from this rule.

Procedural Posture

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

Legal Issues

  1. 1 Whether the Synch Patent is invalid for obviousness
  2. 2 Whether the trial judge erred in claim construction regarding 'preprocessing' and 'up-to-date frequency measurements'
  3. 3 Whether the lock-on synchronisation feature was obvious

Ratio Decidendi

The Synch Patent is invalid for obviousness under the construction adopted by the trial judge, which was correct. The features of preprocessing and up-to-date frequency measurements are not limited as IPCom contended, and the lock-on synchronisation feature is obvious. The trial judge was right to refuse permission for post-trial amendment of the Access Rights Patent; procedural fairness and established principles preclude a second trial on validity after the patent has been found invalid. There was no error of principle or exceptional circumstance to justify departing from this rule.

Court Disposition

Appeal dismissed; trial judge affirmed
