Our analysis

Summary

The pleas that the Court’s jurisdictional framework is incompatible with EU law, and that the absence of a London section of the Central Division infringes the right to a tribunal established by law, are rejected. The appeals are dismissed, as are the request for consolidation of costs and the respondents’ requests for allocation of costs.

Why it matters

The decision concerns the institutional architecture of the Court rather than standard essential patent litigation. Frontal challenges to the Court’s institutional legitimacy did not succeed before the Court of Appeal.

Practical point

Useful effort goes into the jurisdiction rules applied case by case, not into challenging the institutional framework itself.
