DUBLIN, January 31, 2014 /PRNewswire/ --
Research and Markets (http://www.researchandmarkets.com/research/z2d4r6/led_phosphor) have announced the addition of the "LED Phosphor Intellectual Property (IP) LED Phosphors and Down-Converters Patent Investigation Report 2013" report to their offering.

Phosphor related intellectual property has been and remains a major driving force with strong impact on the shape of the LED industry.
LED phosphor IP is shaping the industry
The first commercial GaN-based blue LEDs were produced in Japan in the mid '90s after researchers Shuji Nakamura at Nichia and Professor Akasaki at Nagoya University (IP assigned to Toyoda Gosei) succeeded in removing some of the major remaining roadblocks associated with this technology (p-doping, epitaxy quality).
Quickly leveraging on this success, some fundamental patents describing the use of a blue LED combined with a phosphor to produce white LEDs were filed by Nichia, Osram, ATMI and others. Those fundamental patents were rapidly followed by a fast growing number of applications through 2005 as an increasing number of companies started to compete in the LED market and new applications in cell phone, laptop and LCD TV display, and general lighting were being addressed.
Phosphor IP is a major force in the LED industry. With more than 40 litigation cases, it is also used as leverage by companies which have negotiated close to 70 licensing and supply agreements to date. It can also be argued that in the first half of the 2000 decade, the strict enforcement and lack of license grants for some fundamental IP related to the design and manufacturing of white LEDs might also have slowed down the progress of the industry by preventing more efficient competition that would allow prices to decrease.
The report identifies the key players with the most relevant IP. It provides an overview, of phosphor related IP litigation and licensing, that has shaped the industry since the mid 90s, as well as a detailed analysis for the major players involved.
