Vringo Infrastructure Inc v ZTE (UK) Ltd

Vringo Infrastructure Inc v ZTE (UK) Ltd

The application to reopen the trial and amend pleadings to introduce new prior art was refused because ZTE could, with reasonable diligence, have found the IS-95 documents before trial; the merits of the new evidence were not sufficiently strong to justify reopening; and finality, efficient use of court resources, and fairness to other litigants outweighed any potential benefit. The application to stay the scheduled patent trial pending the FRAND trial was also refused as the shape of the FRAND trial was unclear and the patent trial remained necessary.

Ratio Decidendi

The application to reopen the trial and amend pleadings to introduce new prior art was refused because ZTE could, with reasonable diligence, have found the IS-95 documents before trial; the merits of the new evidence were not sufficiently strong to justify reopening; and finality, efficient use of court resources, and fairness to other litigants outweighed any potential benefit. The application to stay the scheduled patent trial pending the FRAND trial was also refused as the shape of the FRAND trial was unclear and the patent trial remained necessary.
