German court rules that Samsung infringes Datang's 4G patents, smartphone sales face major impact

According to news on April 28, a high-profile patent infringement case recently made a first-instance judgment at the Munich District Court in Germany. It is reported that the mobile communication equipment produced by Samsung Electronics was suspected of infringing the 4G standard essential patent held by Datang, and the court ruled that it was an infringement.

The patented technology involved in this case is the key to enabling mobile phones to seamlessly switch between different TDD frequency bands. This technology ensures that mobile devices can maintain a stable connection during movement. Datang officially obtained the patent rights for this technology in Germany from the China Academy of Information and Communications Technology on August 20, 2021.

According to the court’s ruling, Samsung must pay fixed compensation for all smartphones it sold in Germany since August 20, 2021 that support 4G networks. At the same time, the court also ruled that all relevant mobile phone models currently circulating on the market need to be destroyed. However, this judgment has not yet had full legal effect because Datang has not chosen to pay a deposit of 2.5 million yuan to temporarily enforce the judgment.

Based on my understanding of the text, the fine-tuned content is as follows: According to the editor's understanding, during the court hearing, Samsung and Datang had a heated argument over the FRAND principle (ie, fair, reasonable and non-discriminatory terms) for the granting of standard essential patents. Samsung insisted that Datang did not provide a reasonable licensing agreement in accordance with this principle and used this as a defense. However, the court did not accept Samsung’s defense and ruled that its defense failed.

The Munich District Court rejected this request and did not suspend the process of the original infringement lawsuit.

A spokesperson for Samsung said in an interview: “Samsung will conduct a comprehensive review of the court’s decision and decide on appropriate legal actions, including possible appeals. We will take appropriate actions based on the court’s decision. Measures to ensure that our customers and their user experience are not affected in any way.”

The above is the detailed content of German court rules that Samsung infringes Datang's 4G patents, smartphone sales face major impact. For more information, please follow other related articles on the PHP Chinese website!
