Procedural Posture

Patent Infringement (discovery Dispute) / Interlocutory Appeal From Prothonotary Discovery Order

Legal Issues

  1. 1 Whether the Prothonotary erred in ordering answers to discovery questions
  2. 2 Whether discovery questions were relevant under Rule 240 and the train of inquiry test
  3. 3 Effect of prior admissions on the scope of discovery

Ratio Decidendi

The appeal was dismissed because the Prothonotary did not err: she correctly applied Rule 240 and the train of inquiry test and had evidence from admissions and cross-examination that Phostech had made process and supplier changes which could reasonably affect infringement, so the ordered discovery was relevant and the appellant failed to show the order was clearly wrong.
