Nichia and Seoul semiconductor white LED ruling dispute lawsuit may strike it big

[BP] the Nikkei news agency reported on the mobile phone LCD panel backlight using white LED creative power, old LED maker Nichia chemical industries and emerging companies in Seoul semiconductor (Seoul Semiconductor) a dispute in the United states. About the Nichia chemical industry held its 4 Creative violations of the right to sue the Seoul semiconductor lawsuit, November 8, 2007 jury verdict.

Nichia said the jury accepted all the Nichia that relates to the American idea right are all valid, and that the Seoul semiconductor products (902 Series) against the creative power, and it is an intentional violation. The Seoul semiconductor believes that the 4 involved in the creation of the right to have no need to bear the liability for damages, the remaining 1 involved in the amount of damages is also very limited, so that the fact that the win in the case of".

According to the introduction of Nichia chemical industries, constitute the amount of damages by the statutory minimum amount of $250 and due to intentional violation of legal fees. The proceedings mentioned in the United States, including US D491538, US D490784, US D499385 and US D503388". Among them, the infringement of US D491538 made a ruling to pay damages.

The focus of the dispute in the dispute - the 902 series of white LED, is from the side of the packaging of radiation called Side View model. Side View white LED is mainly used for LCD panel backlight, etc.. Seoul semiconductor said that the ruling of the object of infringement - the 902 series is to provide U.S. companies with a sample of 300 (sales of $165), the 902 series is scheduled to stop the model.

Estimated after the ruling, 1 to 2 months of internal audit will make the final judgment. Seoul semiconductor said it would appeal to the U.S. Court of Appeals for the federal circuit if it failed in the final judgment, insisting that it would not violate the rights of creativity and originality.

Now the patent infringement of Seoul semiconductor Nichia sued

The above is issued for 06 years in January, Nichia chemical industries filed in northern California Federal District Court lawsuit verdict. The company and the Seoul semiconductor lawsuit is not just that, in South Korea and Japan have also been a dispute. Especially recently, the United States patent holders of Seoul semiconductor to the company's infringement on the grounds that the Nichia chemical industries on the Texas Eastern Federal District court.

Seoul semiconductor claims to be infringed by the U.S. patent for "US 5075742", the semiconductor layer structure related technologies, can improve the luminous efficiency. The technology is not only suitable for LED, but also for semiconductor lasers. The company believes that Nichia chemical industries engaged in all LED products are the patent infringement.

The white LED market will continue to expand, not only in the field of mobile phone applications continues to expand, the future will be applied to the notebook computer, LCD and LCD panel backlight field, then lighting equipment market, vehicle equipment market. Due to the huge market demand, more and more LED manufacturers began to sign a cross licensing agreement and other ways to strengthen cooperation. Nichia chemical industry and Seoul semiconductor respectively and other well-known LED vendors to strengthen cooperation. In this context, it can be said Nichia chemical industry and Seoul semiconductor manufacturers in LED between the rare disputes. For the plan to launch LED products with emerging market firms, starting from the LED point of purchase, will pay close attention to the dispute trends of Nichia chemical industry and Seoul semiconductor.
