Recently, a patent dispute between Japanese LED giants and Chinese Taiwanese companies has shaken the nerves of the Chinese LED industry. The reason is that the international LED giants familiar with the past have been fighting each other, and this time they have chosen the battlefield in mainland China. On March 24, Japan’s Nichia Chemical Industry Co., Ltd. (hereinafter referred to as Nichia) announced that it had filed a lawsuit against Beijing Taiwan’s Yiguang Electronics Industry Co., Ltd. (hereinafter referred to as Yiguang Electronics) for alleged patent infringement. .

Industry experts immediately pointed out that although on the surface this is a patent dispute between two non-Chinese mainland companies, the choice of direct "crossfire" in the Chinese mainland market is quite intriguing. "Before, the parties involved in the lawsuit have conducted several rounds of litigation in the United States and other places, and this time once again 'war in China', which is particularly important for LED companies in mainland China." LED industry The relevant person in charge of the patent alliance said in an interview with the China Intellectual Property News that the patent "mixed war" between multinational giants will directly change the pattern of China's LED industry. Only relevant enterprises can strengthen their intellectual property rights to find a transformation. The way out for the upgrade.

International LED patent disputes

Patent giant melee

"In order to demonstrate the determination of Nichia Chemicals to protect intellectual property rights, it filed a lawsuit against the China Electronics Co., Ltd. and its authorized dealers in the Beijing Intellectual Property Court, requesting a permanent injunction and damages." In the information released by Nichia to the media a few days ago, The details of the lawsuit were disclosed in detail.

“Yiguang Electronics firmly believes that these two patents do not comply with the provisions of the Chinese Patent Law and will assist dealers in counterattacking. Yiguang Electronics reiterates its consistent position of respecting intellectual property rights and will fully defend its customers and shareholders' rights.” Faced with the tightening of Nichia Forced, the counterattack of Yiguang Electronics was also very decisive, and gave his attitude on March 24th.

Although the attitudes of both parties involved were decisive and decisive, the focus of the LED industry in mainland China was the key details behind the case: In the interview, the reporter noted that the patent involved in this case was in the Japanese patent white LED patent group. The two core invention patents, and around the two patents related technology and other family patents, Nichia has previously launched a five-year patent litigation in the United States with Everlight. Last year, the Eastern District Court of the State of Michigan in the United States had already made a judgment that was not creative and unenforceable for Nichia’s two family patents. In this regard, Liu Guang, Assistant General Manager of Everlight Electronics, admitted in an interview with this reporter: "Although Everlight Electronics can reach a patent cross-licensing agreement with Nichia Chemical as the end of the dispute, only the above two patents will be invalidated. Only in order to completely untie the development of the industry, and promote the development of the LED application market."

"Contacting the ongoing contest between the two parties involved in the fight for the US market, it can be said that this time the 'war" has been burned to mainland China. The person in charge of the LED industry patent alliance pointed out that overseas LED giants have started patent wars in China, regardless of It is the settlement of the litigation process, or the patent cross-licensing and the out-of-court settlement. The result will be to further strengthen the white LED patent protection in the Chinese mainland market. While the mainland LED industry is still in the process of intensifying homogenization competition due to the lack of core intellectual property rights, international giants have begun to launch patent "mixed wars" in the Chinese mainland market, which will undoubtedly be urgently needed to break through the patent containment and realize the transformation and upgrading of mainland China. The LED industry has caused an impact.

Achieve overtaking

As the above-mentioned person in charge said, statistics from the State Intellectual Property Office show that in recent years, the number of patent applications in the field of LED technology in mainland China has surpassed that of the United States in the second place, but mainly concentrated in the middle and lower reaches, midstream packaging and Low-value-added patent applications such as downstream applications accounted for 64% of the total number of patent applications.

“In recent years, the five major LED giants such as Osram, Cree, Nichia, Toyota Synthetic and Philips have not only formed a patent protection cross-licensing agreement through patent litigation on a global scale, but also become a strict patent protection network. "The sword of Damocles hanging over the top of Chinese enterprises." Wang Guohong, general manager of Yangzhou Zhongke Semiconductor Lighting Co., Ltd. (hereinafter referred to as Zhongke Semiconductor) told this reporter that in this situation, LEDs in mainland China In order to comprehensively circumvent the risk of infringement and even achieve the “overtaking of the curve”, enterprises must increase R&D efforts and accumulate more core patents on the basis of complying with the international intellectual property rights rules.

Take the Jiangsu Yangzhou Economic and Technological Development Zone where Zhongke Semiconductor is located as an example. In recent years, in the process of participating in the pilot project of intellectual property cluster management in strategic emerging industries, a group of LED companies such as Zhongke Semiconductor have fully adopted the policy to start the journey of relying on intellectual property to achieve transformation and upgrading. Among them, Zhongke Semiconductor has submitted more than 50 patent applications in China, and through the provincial and municipal level three-level capital policy guidance, the company submitted two international patents through the Patent Cooperation Treaty (PCT) route to the world's major export markets last year. Apply to comprehensively evade the risk of overseas infringement; Yangzhou Ganzhao Optoelectronics Co., Ltd., which is not far from Zhongke Semiconductor, invests 5% of its annual sales revenue in research and development. Since its establishment, it has submitted 20 in just over a year. The remaining Chinese patent applications, including 8 invention patent applications, the core technology patent layout promoted the annual sales revenue of this startup company exceeded 300 million yuan.

In Hangzhou, Zhejiang, Hangzhou Huapu Yongming Optoelectronics Co., Ltd. (hereinafter referred to as Huapu Yongming), which focuses on high-power LED outdoor lighting, has embarked on a development path of “business model approach, patent strategy and enterprise”. Huapu Yongming, general manager of Chenpu, told this reporter that, while actively pursuing independent innovation, Maple Yongming also signed an agreement to waive patent risks with LED giants such as Philips, and solved patents that may be faced by its products through patent licensing. risk. “Submitting patent applications around the core technology to carry out patent distribution on a global scale, and opening up the upstream and downstream of the industry chain to avoid patent infringement risks through cross-licensing. This development concept has made Huapu Yongming have no patents in the case of continuous disputes in the LED field. Infringement disputes." Chen Kai said.

The relevant person in charge of the LED Industry Patent Alliance said that in recent years, the practice of some LED companies in mainland China has proved that blindly expanding market share is not a good strategy for development. While opening up the market, it is also necessary to strengthen independent innovation and actively carry out patent distribution. Through the transformation and upgrading of intellectual property rights, we can truly change the existing LED industry development pattern.

Mini USB

Antenk mini usb:The small USB socket found on digital cameras, external hard drives, USB hubs and other equipment. Mini USB is much smaller than USB Type A and B but twice as thick as Micro USB (see illustration below).

MINI USB, also known as Mini USB, is a USB interface standard. USB is the abbreviation of universal serial bus in English, which means "universal serial bus" in Chinese. It is a technology developed for data transmission between PC and digital devices. Standard USB, MINIUSB and microusb have become the most common USB interfaces. Compared with standard USB, MINIUSB is smaller and suitable for small electronic devices such as mobile devices.

Mini USB is divided into a type, B type and ab type. Minib type 5pin interface is the most common interface. Due to its excellent anti misplug performance and small size, it is gaining the favor of many manufacturers. This interface is widely used in card readers, MP3, digital cameras and mobile hard disks.

The ID foot is only used in OTG function. The Mini USB interface is divided into mini-a, B and ab interfaces. If your system is only used as a slave, then use the B interface. The system controller will judge the level of the ID pin and determine what kind of device is inserted. If it is Gaoping, it is the B connector. At this time, the system will do slave mode. If the ID is low, it will be a interface. Then the system will use HNP dialogue protocol to decide which is the master and which is the slave
OTG is the abbreviation of on the go, that is, OTG technology is to realize the data transmission between devices without host. It is mainly used in the connection between different devices or mobile devices for data exchange. For example, the digital camera is directly connected to the printer, and through OTG technology, the USB port between two devices is connected to print out the photos taken immediately; the data in the digital camera can also be sent to the mobile hard disk of USB interface through OTG, so there is no need to carry expensive memory card or carry a portable computer for field operation.

Except for pin 4, other interface functions of Mini USB are the same as those of standard USB. The fourth needle becomes the ID, which is connected to the fifth needle on the mini-a, and can be suspended in the mini-b or connected to the fifth needle.
