In today's society, price competition is generally recognized as the lowest-end competition and the competition without the most technological content, and it is competition without any benefits at all. Then what is the core of the competition? LED lighting manufacturer C-Star believes that the core competitiveness of the company is technology and patented technology. I like Gree ’s advertising. Gree masters core technology. Only mastering core technology can occupy a leading position in the fierce market competition. Defeated! Let's take a look at the seven major patent litigation cases in the LED industry. All major manufacturers have gone to court for patents!
On March 24, 2016, a federal judge in California issued a judgment announcing that Japanese manufacturer Enplas intentionally infringed Seoul Semiconductor's LED backlight patent.

According to information from the US legal media, Vizio ’s LCD TV products use LED backlight modules from Taiwanese manufacturers. The LED chip products used by Vizio were identified as infringing products by Nichia, so they sued the LCD TV factory.
It is understood that the infringing LED product models of Guangjun are "BN-D4242J-A3", "BN-D4242E-A3" and other infrared LED chips, which have infringed on the ownership of Jingdian including Taiwan inventions No. 141155, No. 170789, 4 invention patents such as No. 202662 and No. I283031.

Previously, Cree launched a patent lawsuit against Taiwan factory Hongqi on September 15, 2014, and Hongqi immediately launched a counterattack. Not only did it file a lawsuit against Cree and its subsidiaries for patent infringement in the United States on December 5, 2014, and in 2015 In July of 1997, on the occasion of legal offense and defense, it successfully invalidated the related Chinese patents of Cree.
