UPC’s Lisbon LD rejects Ericsson’s attempt to render Transsion SEP suit “devoid of purpose”

Context: On March 6, 2026, China’s Transsion sued four Ericsson entities at the Unified Patent Court’s (UPC) Lisbon Local Division (LD) over EP4123910 (“Information indication method and related product”), seeking injunctive relief and related remedies (March 26, 2026 ip fray article). The Lisbon case forms part of a broader global SEP dispute between the parties. Ericsson has simultaneously pursued multiple UPC infringement actions of its own, while also asking the Hague LD to determine fair, reasonable, and non-discriminatory (FRAND) terms for a worldwide cross-license covering both parties’ 4G and 5G SEP portfolios. Separately, an Ericsson group entity yesterday filed a standalone revocation action against EP’910 before the Paris seat of the UPC’s Central Division (CD) (May 27, 2026 ip fray article).
