MediaTek, Inc & Ors v Huawei Technologies Co, Ltd & Anor [2025] EWHC 1857 (Pat) (17 July 2025)

MediaTek, Inc & Ors v Huawei Technologies Co, Ltd & Anor [2025] EWHC 1857 (Pat) (17 July 2025)

Disclosure of Huawei's four infrastructure licences is ordered as their data may assist the trial judge and the burden is limited. Disclosure by MediaTek of documents on SEP licensing level is refused due to disproportionate burden and unclear relevance. Extension of MediaTek's summary disclosure to other infringing acts is refused at this stage due to lack of clarity in pleadings and potential burden, but may be revisited. MediaTek is ordered to use best endeavours to obtain essentiality assessments from patent pools as the burden is not excessive and the information may be valuable.

Procedural Posture

Patent Litigation / Case Management Conference (cmc) – Interlocutory Disclosure Orders

Legal Issues

  1. 1 Whether Huawei should disclose four infrastructure licences to MediaTek
  2. 2 Whether MediaTek should disclose documents relating to the level at which SEPs should be licensed (chip or device level)
  3. 3 Whether MediaTek should extend summary disclosure to include acts of infringement beyond manufacture and sale

Ratio Decidendi

Disclosure of Huawei's four infrastructure licences is ordered as their data may assist the trial judge and the burden is limited. Disclosure by MediaTek of documents on SEP licensing level is refused due to disproportionate burden and unclear relevance. Extension of MediaTek's summary disclosure to other infringing acts is refused at this stage due to lack of clarity in pleadings and potential burden, but may be revisited. MediaTek is ordered to use best endeavours to obtain essentiality assessments from patent pools as the burden is not excessive and the information may be valuable.
