I want to know the answer to the following question:
How many companies did a judge say infringed on Dr. Moustakas's prior blue light patent in 2015?
All the background I'm provided with is that "Nakamura, Hiroshi Amano and Isamu Akasaki were awarded the Nobel Prize in Physics in 2014 for the invention of the blue LED.". Is that enough to answer the question?
Answer: no
