A few days ago, the international football top event Brazil World Cup has entered the knockout round, Spain, Italy, England and other traditional European teams have been out, it is inevitable. Success or failure has never been eternal. The same is true for the LED industry. In the current world war, winning and losing is within easy reach. How to win? For LED companies, first use the patent as a weapon to arm themselves. The battle for the LED patent world was launched in 2014. In the LED industry, the patent warfare gradually spread. According to the "LED Patent Trend Analysis Report" of the Guangdong Semiconductor Lighting Industry Joint Innovation Center (GSC), as of May this year, the global LED patent litigation cases have reached more than 20, especially for overseas companies. Up to 20 pieces. Among them, there are more and more patent litigations initiated by Nichia, and the battle with Yiguang is more intense. Nichia has filed as many as 18 patent claims against Yiguang, and the courts in Europe, the United States and Japan have spread the patent fireworks of the two companies. In addition, Intel and Mitsubishi have also filed lawsuits, and Boston, which is considered by the industry to be close to Cree, is also actively expanding the scope of patent litigation. According to Dr. Li Wenyu, Director of the Strategic Research Department of the Joint Innovation Center of the Semiconductor Lighting Industry of Guangdong Province, behind the increasing number of LED patent litigation is the game of the interests of the LED industry. With the LED lighting entering the golden period of development, LED large enterprises will step up the use of patents to grasp the market leading power, and the patent war will be in a normal trend. As China's LED companies have grown and their market position has become increasingly prominent, it is only a matter of time before Chinese companies face patent litigation by international giants.
