Procedural Posture

Patent Infringement and Revocation Proceedings / Interlocutory Applications for Unless Order and Further Disclosure

  1. 1 Whether the fifth defendant should be debarred from contesting the counterclaim for failing to serve a defence
  2. 2 Whether further disclosure should be ordered against the fifth defendant beyond the standard four-year window
  3. 3 Whether the pleadings are sufficiently particularised to justify further disclosure

Ratio Decidendi

The court held that the fifth defendant, having unequivocally stated it would not serve a defence to the counterclaim, should be debarred from adducing evidence or calling witnesses to contest the counterclaim. On disclosure, the court found the pleadings sufficiently particularised to justify further disclosure beyond the standard four-year window, but limited the scope of disclosure to proportionate and relevant categories, balancing the need for disclosure against the risk of fishing and undue burden.

Court Disposition

Applications granted in part

Orders

  • Fifth defendant debarred from adducing evidence or calling witnesses to contest the counterclaim.
  • Order for further disclosure against the fifth defendant, extending the disclosure period and specifying categories of documents to be disclosed, subject to proportionality and relevance.
