MMI Research Ltd v Cellxion Ltd & Ors

MMI Research Ltd v Cellxion Ltd & Ors

The defendants failed to establish that the manuals and disk were supplied to the Italian Carabinieri or German BKA before the priority date free of confidentiality obligations. The provenance and authentication of the English File and Italian Manual were inadequate, and any supply would have been subject to Rohde & Schwarz’s General Conditions, which imposed confidentiality. Therefore, the new evidence did not establish prior use invalidating the patent.

Procedural Posture

Patent Action (remitted Issues) / Judgment After Remittal From Court of Appeal on New Evidence of Alleged Prior Use

Legal Issues

  1. 1 Whether new evidence establishes prior use invalidating the patent
  2. 2 Whether manuals and software were supplied without confidentiality obligations
  3. 3 Whether the evidence of supply and authentication of manuals and disk is sufficient

Ratio Decidendi

The defendants failed to establish that the manuals and disk were supplied to the Italian Carabinieri or German BKA before the priority date free of confidentiality obligations. The provenance and authentication of the English File and Italian Manual were inadequate, and any supply would have been subject to Rohde & Schwarz’s General Conditions, which imposed confidentiality. Therefore, the new evidence did not establish prior use invalidating the patent.

Court Disposition

Defendants' case on remitted issues dismissed; patent remains valid.
