I want to know the answer to the following question:
Who first patented a method to produce high-brightness blue LEDs?
All the background I'm provided with is that "Two years later, in 1993, high-brightness blue LEDs were demonstrated again by Shuji Nakamura of Nichia Corporation using a gallium nitride growth process similar to Dr. Moustakas's.". Is that enough to answer the question?
Answer: yes
