Seoul semiconductor shot again, accusing Mouser of infringement of high-power LED patents

The world famous LED manufacturer of semiconductor in Seoul said in April 13th that the global electronic components distributor Mouser Electronics high power LED company violated its patents, has filed a lawsuit in the Dusseldorf District Court in germany.

According to the Seoul semiconductor related sources, patent infringement products are high-power LED ten of the world's largest LED manufacturer - Everlight electronics and most of the LED manufacturers, Mouser has become the object of litigation because the sale and circulation of these manufacturing enterprises LED products. Proceedings, the Seoul semiconductor requirements of these infringing products issued an injunction prohibiting the recall and destruction of infringing products and compensation for damages.

High power LED technology is widely used in mobile phones, automotive headlights, street lights and other outdoor lighting and UV LED products. The patented technology through processing on the surface of LED chip, LED chip effectively generated light is released to the LED chip external, thereby greatly enhancing the light intensity and brightness, is necessary to use high efficiency LED the manufacturing requirements.

Global LED market size reached 15612$M in 2016, which accounted for 43% of high-power LED market LED, about 6722$M scale. As of 2020, the global LED market size is expected to reach 19240$M, accordingly, high-power LED market will also be substantial growth. The proceedings involving high-power LED patented technology is widely used in the 6722$M scale LED market, is expected to further increase the patent litigation related to high power LED.

Seoul semiconductor will start this lawsuit, severely deal with violations of its high-power LED technology behavior. In addition, the violation of the Seoul semiconductor LED packaging and chip related patents have been confirmed, Seoul semiconductor companies are discussing the relevant patent litigation filed.

Seoul semiconductor annual sales of more than 10% of R & D, with a total of 12000 patents, the patent strength of the world recognized. Seoul semiconductor since its inception, in all patent litigation has never lost, created the myth of winning. In the past 2013, the United States electrical and Electronics Institute (IEEE) released by the semiconductor industry patent strength ranking, Seoul is the only elected LED semiconductor manufacturing enterprises, and is the second in 2012, for two consecutive years was named LED patent strength first in the world.

IEEE year selected the industry ranked patent strength released in the United States is the world's more than 5 thousand patent holding enterprises, universities, government agencies such as the application number, patent, patent, patent growth index evaluation index to evaluate the. Through this ranking, you can measure the technical strength of enterprises in their respective fields.

Seoul semiconductor research center, vice president of Ki-bum Nam said, high-power LED technology as a chip processing technology is widely used in the field of LED, is the core technology to lead the future of the LED market patents. Recently, in the field of LED, the patent infringement of the circulation of counterfeit products increased dramatically, so we filed this lawsuit." He stressed that, in order to create a better and more convenient life, we must continue to introduce innovative products; in order to achieve such an ideal, we should take action to resolutely deal with violations of patents, intellectual property protection."

High power LED applications

(1) automobile

According to market research firm HIS survey results, 2016 LED penetration rate of 16.4% vehicles, is expected by the end of 2021 will be sharply increased to 32.3%. High power LED technology has been successfully applied to the automobile headlamps, daytime running lights such as exterior lighting, in order to improve energy efficiency, it is expected that it will become the requirements of high-power and high radiation LED lighting technology of electric vehicles, unmanned vehicles needed technology.

(2) IT

High brightness mobile phone LED is also used with high-power LED. Flash LED with a higher profit margin than the LED backlight, so even though the entire field of IT growth rate is reduced, but it still maintain growth trend. With the improvement of the performance of mobile phone camera, the number of LED is also increasing.

(3) lighting

High power LED technology can improve the brightness of the LED unit area by improving the light efficiency of power chip, which is suitable for outdoor lighting, commercial and industrial lighting. Expected to account for half of the overall market share of the LED lighting market with LED, high power LED technology related patent disputes will further increase.

(4) UV LED

High power LED can also be applied to sterilization, purification, curing and other functions of UV LED. As of 2020, UV LED application market size is expected to grow sharply to 800$M, therefore, will accelerate the application of high-power LED patented technology in the field of UV LED.
