Based on our tracked database, Hisense Co., Ltd. appears as a defendant in one U.S. patent litigation case. However, Hisense is an active operating company that engages in two-way patent litigation.

The case Nokia Technologies Oy v. Hisense Co., Ltd. et al., filed in April 2025, involved claims related to H.264 and H.265 video decoding standard-essential patents (SEPs). This was part of a broader multi-jurisdictional dispute, which also saw Hisense Visual Technology Co., Ltd. filing a counterclaim against Nokia of America Corporation in the U.S. District Court for the Eastern District of Texas concerning patents related to edge systems and private wireless networks. Both parties' lawsuits were voluntarily dismissed following a global settlement and licensing agreement. Hisense's portfolio growth is also supported by strategic acquisitions, including Toshiba's visual solutions business and Slovenian appliance manufacturer Gorenje.
