Seoul semiconductor once again shot, accusing Mouser of infringing 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. In the lawsuit, Seoul semiconductor asked for infringement, injunction, recall and destruction of infringing products and damages for the infringing products.

High power LED technology is widely used in mobile phones, flash lights, car 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 scale in 2016 reached 15612$M, of which high power LED accounted for 43% of the entire LED market, about 6722$M scale. As of 2020, the global LED market is expected to reach 19240$M, according to this, the high-power LED market will also be substantial growth. The lawsuit involving high-power LED patent technology is widely used in the 6722$M scale LED market, is expected to power LED related patent litigation will increase further.

Seoul semiconductor will take the lawsuit as the start and deal severely with its aggressive LED technology. In addition, the infringement of Seoul semiconductor LED packaging and chip related patents have been confirmed, Seoul semiconductor is discussing additional patent litigation related enterprises.

Seoul semiconductor annual sales of more than 10% of R & D, with 12000 patents, its patent strength has been recognized worldwide. Seoul semiconductor since its inception, in all patent litigation has never lost the lawsuit, created a winning myth. 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 5000 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 Central Research Institute Ki-bum Nam vice president said, "high-power LED technology as a chip processing technology is widely used in the entire LED field, is to lead the future LED market core patented technology.". Recently, the LED sector has witnessed a dramatic increase in the flow of patented Shanzhai products, so we filed this lawsuit." He stressed that "to create a better and more convenient life, we must continue to introduce innovative products; in order to achieve this ideal, we should take action to resolutely respond to patent infringement and protect intellectual property rights."."

High power LED application areas

(1) car

According to market research firm HIS survey results, in 2016, LED penetration rate of 16.4% vehicles, is expected by 2021 will rise sharply 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 flash, LED is also used in high-power LED. Flash LED is much more profitable than LED for backlighting, so it continues to grow despite a slowdown in overall IT growth. With the improvement of mobile phone camera performance, the number of LED used is also increasing.

(3) lighting;

High power LED technology can enhance the brightness of LED per unit area by improving the luminous efficiency of power chip, and can be applied to outdoor lighting, commercial and industrial lighting with high luminous efficiency. It is estimated that in the lighting LED market, which accounts for half of the total LED market, the patent disputes concerning high power LED technology will be further increased.

(4) UV LED

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