MMI Research Ltd v Cellxion Ltd & Ors [2011] EWHC 426 (Pat) (07 March 2011)

MMI Research Ltd v Cellxion Ltd & Ors [2011] EWHC 426 (Pat) (07 March 2011)

The defendants failed to establish, on the balance of probabilities, that the manuals or floppy disk were supplied to the Italian Carabinieri or other customers before the priority date free of confidentiality obligations. The provenance and authenticity of the new evidence were not sufficiently proven, and any supply would have been subject to confidentiality under the contractual terms. Therefore, the patent remains valid and was not anticipated by prior use.

Procedural Posture

Patent Infringement and Validity / Remitted Trial on New Evidence Regarding 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 restrictions
  3. 3 Whether the alleged prior use was sufficiently proven and public

Ratio Decidendi

The defendants failed to establish, on the balance of probabilities, that the manuals or floppy disk were supplied to the Italian Carabinieri or other customers before the priority date free of confidentiality obligations. The provenance and authenticity of the new evidence were not sufficiently proven, and any supply would have been subject to confidentiality under the contractual terms. Therefore, the patent remains valid and was not anticipated by prior use.

Court Disposition

Defendants' case on invalidity based on new evidence dismissed; patent remains valid.
