Four years ago, Taiwan’s LED company Yiguang Electronics Industry Co., Ltd. (hereinafter referred to as Yiguang Electronics) patented two white LEDs of Japan Nichia Chemical Industry Co., Ltd.

Four years ago, Taiwan’s LED company Yiguang Electronics Industry Co., Ltd. (hereinafter referred to as Yiguang Electronics) patented two white LEDs of Japan Nichia Chemical Industry Co., Ltd. (hereinafter referred to as Nichia) in the Eastern District of Michigan, USA. Propose that the patent is invalid and does not constitute an infringement. After many years of trials, the case had the latest results. The US District Court for the Eastern District of Michigan decided to defeat Nichia Chemical on the grounds that the two patents were not creative and not enforceable. When the news came out, it caused a lot of shock in the industry.

In recent years, LED international giants represented by Nichia Chemicals have used their strong patent reserves to continuously pressure Chinese LED companies. China's LED companies are under unprecedented pressure. In this regard, industry experts said that the success of Yiguang Electronics has positive significance for domestic related enterprises. Domestic related enterprises should continuously strengthen independent research and development, promote industrial upgrading, actively carry out patent distribution, and enhance their own strength while exploring the market. Enhance the voice and dominance of Chinese LED companies in the international market.

Foreign giants trigger patent litigation

In the interview, the reporter learned that as a giant in the LED industry, Nichia has a large number of basic patents and has an absolute monopoly in the LED field. These patents cover the entire process manufacturing technology of LED structures, epitaxy, chips, packages, and related raw materials such as phosphors. However, in recent years, with the rise of domestic LED companies, Nichia has been using patents that continue to make trouble for Chinese companies.

According to industry insiders, in order to control the entire LED market, Nichia has used its basic patents to suppress competitors. On the other hand, it has separated the majority of rising stars from high-profit markets through patent networks woven by patent cross-licensing. . "Although Everlight Electronics can achieve cross-licensing with Nichia Chemical as the end of the dispute, only by invalidating the above two patents can we completely untie the development of the industry and promote the development of the LED application market." Assistant Liu Wei said in an interview with the China Intellectual Property News reporter.

"If you want to become an international LED company, you not only need to save 'patent muscles', but also need to compete with the giants." Wang Hua, deputy secretary general of the LED Industry Patent Alliance, said in an interview with this reporter that Yiguang Electronics passed this The success of the second lawsuit invalidated two patents of Nichia Chemical, which caused widespread concern in the industry. With the increasing number of patents owned by companies such as OSRAM, Toyota Synthetic, Cree, Philips, etc., Nichia has gradually entered into a patent settlement and licensing agreement with the above companies, basically adopting litigation - settlement - cross-licensing Mode. The patent of Nichia Chemical was invalidated, indicating that the patent network built by the giants through patent cross-licensing has begun to loosen and will begin to build a new white LED patent layout, which will provide new development opportunities for domestic enterprises. While developing the market, domestic enterprises can strengthen independent research and development, promote industrial upgrading, actively carry out patent applications and layout, and change the existing development pattern by improving their own strength.
