LED Lighting - Key Patent Analysis: COB LED
This report was written to provide information on patent technology trends of Korea and foreign countries on recent biggest issue [COB LED]

In recent LED lighting market where the LED price is dropping, various technology development is being attempted as solutions for improving high power, thermal efficiency and luminous efficiency are becoming more important than ever. Among many technologies COB LED is receiving much attention from many companies as it can deliver low cost LED having strength in power, slimming/miniaturizing , efficiency enhancement, lifespan, stability and reliability.

The leading companies of US and Japan filed for COB LED patent application from mid-2000s. And in recent years, global manufacturers including CREE, Citizen, Bridgelux and Osram are continuously releasing results of technology development.

As shown in the report most of the key patents are from small group of leading companies and from specific countries. The analysis of Chip-on-Board LED key patent examined by each company also shows the leading companies to share most of the key patents.

In general a patent is open to the public after year and a half from the time of filing. And so, it is important to check the patent status in a regular basis as new technologies developed by leading companies that have been filed for application are not yet opened to the public.

As COB LED is an area where patent dispute is expected, it is suggested for companies to carefully analyze the key patents of major companies and prepare defense patents, obtain invalid patent information and develop ways to design around patents.
