일본도 못 만드는 LED, 서울의 작은 상가에서 시작한 회사가 특허 18,000개로 세계를 평정했다

There was a company that started in a single small commercial unit. Its revenue was a mere 1 billion won. It had only a few employees. However, 30 years later, this company astonished the entire world. 18,000 patents. LEDs that even Japan cannot manufacture. It defeated the world's largest Japanese company head-on. The U.S. court and the courts of 18 European countries all sided with Korea.
