- •Thales challenged the court's jurisdiction and sought a stay, arguing Kigen had no obligation to take a licence.
- •Kigen initially claimed a free-standing FRAND licence but later clarified its willingness to take a licence only if the patents were found valid and essential.

Legal Principles
Jurisdiction to set FRAND licence terms for a global portfolio of related patents, even if lacking jurisdiction over foreign patents.
Unwired Planet v Huawei [2020] UKSC 37
An unwilling licensee defendant cannot decline to give an undertaking and resist an injunction pending FRAND term determination after infringement.
Optis v Apple, Trial F, [2022] EWCA Civ 1411
Abuse of process if a claimant pursues a FRAND claim without an undertaking to take a licence, especially if costs might exceed licence value.
Judgement in this case
Outcomes
Stay of the FRAND claim granted.
Kigen's position changed from a free-standing claim to a licence as a defence, creating an abuse of process. Unless Kigen amends its claim to reflect this or provides an undertaking to take a licence, the FRAND claim is stayed.
Thales to receive two-thirds of its costs.
Thales was the overall successful party, though it failed on several grounds, and significant time was spent by both sides addressing arguments.
