The patent - related communication dispute between Datang Mobile and Xiaomi is set to go to trial in a local German court in March 2026. Back in June of this year, Datang Mobile initiated a lawsuit against Xiaomi in Germany, and as of now, the dispute has yet to reach a resolution.

According to individuals well - versed in the matter, the root cause of the legal tussle between the two entities lies in the fact that the licensing fee proposed by Datang Mobile to Xiaomi is significantly higher compared to what it charges overseas manufacturers like Apple and Samsung, bordering on an excessively high amount. In the past, Datang Mobile has been involved in patent disputes with companies such as Apple, Samsung, and Lenovo.

In 2021, Apple paid Datang Mobile a hefty sum of US$95 million in patent licensing fees. Based on this benchmark, a reasonable licensing fee for Xiaomi would be around US$13 million. In April 2025, Datang Mobile entered into a patent cross - licensing agreement with Lenovo. However, the patent fee rate it imposed on Lenovo was also higher than the rate it charged Apple.

Given that the patents in question are standard essential patents, Datang Mobile is under a legal obligation to grant licenses. Moreover, it is required to charge fees in strict accordance with the principles of fairness, reasonableness, and non - discrimination.
