Seoul searches for reversal of patent verdict

Seoul Semiconductor wants a California federal court to reverse a ruling for willful infringement of four Nichia LED design patents – see Nichia and Seoul offer different views of jury ruling.

Seoul has filed a post-verdict motion in the U.S. District Court for the Northern District of California for a judgment as a matter of law that Nichia's patents are not infringed, and are invalid. The Korean LED maker claims there was insufficient evidence for a jury to reach the verdict.

Obducat supplies Luminus

Obducat, the Sweden-based manufacturer of nanoimprint lithography equipment, has revealed that it has supplied "at least two" manufacturing tools to Luminus Devices, the US-based high-power LED maker.

The information was revealed in an article in Swedish on Obducat's website. Luminus uses the equipment to manufacture photonic lattice crystals structures, which are a critical to its PhlatLight LEDs. Obducat has also supplied equipment to Epistar, a Taiwan-based LED maker.

* Luminus has announced a new distributor in China, Taiwan, Korea, and Mexico – see Luminus Devices adds distribution partner Toyota Tsusho.

Enphos becomes Zyphos

Following a legal dispute lasting several months over the use of the name "Enphos" when associated with LED products, Enphos LED Systems Limited has changed its company name to Zyphos, effective March 1, 2008.

Enphos was founded in October 2007 – see news. Problems arose due to confusion with the established LED array manufacturer Enfis plc. Zyphos Managing Director Kevin Knight said, "We confirm that the company never was associated with or in any way intended to be confused with Enfis plc."
