(JW Insights) Nov 3 -- South Korea's Samsung Electronics and its US subsidiary initiated a patent invalidation declaration against China Datang Mobile Communications Equipment (大唐移动) in the US District Court for the Eastern District of Virginia on October 31.

Samsung said that Datang Mobile violated FRAND obligations and the principle of good faith negotiation; In addition, Samsung also mentioned Datang Mobile filed an infringement and rate ruling lawsuit against it in the Fuzhou Intermediate People's Court of China in December 2022. In addition to requesting the court to set 4G and 5G license rates, it also requested an injunction. Samsung believes that using the threat of a ban to achieve reverse phase hijacking also violates the FRAND principle and the principle of good faith negotiation.

Samsung also questioned the quality and value of Datang Mobile's patents.

On February 6, 2023, Datang Mobile's patent company announced that Datang Mobile had filed a lawsuit over disputes on infringement of invention patent rights with Samsung China. The lawsuit involves six cases, and the total amount involved in the six cases was RMB 123 million ($16.82 million).

In a separate development, Samsung Display has filed an International Trade Commission (ITC) lawsuit against BOE - China's leading display manufacturer, claiming that it misappropriated Samsung Display's trade secrets on November 2, according to the commission's document.

ITC documents show that Samsung Display filed the lawsuit on October 31, accusing BOE of violating a US "unfair competition method" regulation, including infringement of trade secrets in OLED display modules and components.

South Korea has been strengthening its monitoring of technology leaks.
