Telefonaktiebolaget LM Ericsson v. Lenovo (United States), Inc., decided 24 Oct 24

This case involves a dispute between Ericsson and Lenovo concerning 5G standard-essential patents (SEPs) and FRAND commitments. Lenovo sought an antisuit injunction to prevent Ericsson from enforcing injunctions obtained in Colombia and Brazil. The Federal Circuit vacated the lower court’s denial of the injunction, finding the lower court erred in its interpretation of the "dispositive" requirement for antisuit injunctions. The court held that the issue of whether Ericsson had fulfilled its good-faith negotiation obligations under the FRAND commitment was dispositive of the propriety of the foreign injunctions.
