On the morning of November 29, Hisense Group announced that its subsidiary, Hisense Electric, has officially filed lawsuits in courts in Beijing and Qingdao. The company is accusing Sharp of infringing on its invention patents with as many as a dozen television models sold in China. This legal action marks a significant step in the ongoing patent dispute between the two major electronics manufacturers.
The patents at the center of this case are two key inventions: “A Backlight Control Method, Device, and LED TV†and “Backlight Drive Circuit and Television.†Both are currently valid and have not expired. These technologies are widely used in modern television manufacturing, making the allegations particularly serious for Sharp.
Hisense claims that the allegedly infringing products are available in over 30 provinces and cities across China. In its formal complaint, the company has requested the court to order Sharp to immediately cease all activities related to the alleged infringement, including manufacturing, selling, and offering to sell the infringing products. Additionally, Hisense is asking the court to mandate the destruction of all infringing goods. Courts in both Beijing and Qingdao have formally accepted the cases, indicating that the legal process has officially begun.
Sina Technology reached out to the person in charge of Sharp’s TV division, but the representative stated that they had not yet received any official notice from the court. This lack of communication raises questions about how Sharp will respond to the allegations, especially given the potential impact on its business operations in one of the world’s largest markets.
This development highlights the growing importance of intellectual property protection in the global electronics industry. As companies like Hisense and Sharp continue to innovate, legal battles over patents are becoming increasingly common. For now, the situation remains under judicial review, and further updates are expected as the cases progress.
