South Korean LED maker Seoul Semiconductor says that, among companies that make LED components only, it was the only one selected by the Institute of Electrical and Electronics Engineers (IEEE) in the top 20 of its 2013 Semiconductor Manufacturing Patent Power Ranking. The firm was also selected in the same category in 2012.
The patent power scorecards by IEEE for each industrial section are based on evaluation of the patent portfolios of more than 5000 leading commercial enterprises, academic institutions, non-profit organizations, and government agencies worldwide. It takes into account not only the size of the organizations patent portfolios but also the quality of their patents with regards to the growth index, impact of the patents, originality, and general applicability of the patents.
Seoul Semiconductor has more than 20 years of experience in semiconductor manufacturing and invests more than 15% of its annual revenue to LED research and development. On average, the firm applies for more than 600 patents every year. Currently, it holds more than 11,000 LED patents, including patents in core LED technologies such as Acrich, Acrich MJT, nPola, TV direct backlight technology, and UV. Seoul Semiconductor says that its patent portfolio in LED technology includes epitaxial growth, fabrication, packaging and system applications.
