Seoul Semiconductor (KOSDAQ:046890), a leading global innovator of LED products and technology, has announced that the International Crimes 4 Team at the Gyeonggi Nambu Provincial Police Agency in Korea is expected to detain three individuals, “A” – a former Managing Director of Seoul Semiconductor, “B” and “C” – former employees of Seoul Semiconductor, who divulged automotive LED technology that cost KRW 560 billion and seven years in development to Everlight Electronics, a competitor of Seoul Semiconductor located in Taiwan.

The three individuals will be charged for violating the Act on Prevention of Divulgence and Protection of Industrial Technology, and the Unfair Competition Prevention and Trade Secret Protection Act, and forwarded for prosecution.

Moreover, the CEO of Everlight Electronics and Everlight itself, both liable for the technology divulgence, have been charged under the Act on Prevention of Divulgence and Protection of Industrial Technology.

A, a former Managing Director of Seoul Semiconductor, took umbrage during his salary negotiations and sought out new employment opportunities using technology illegally obtained from Seoul Semiconductor as leverage. During the course of his search, A agreed to join Everlight Electronics in Taiwan as a high-paid Vice President.

Furthermore, investigations revealed that A attempted to use the information he gleaned illicitly from Seoul Semiconductor to develop an LED product for automotive headlights. To expedite development, A offered B and C, both researcher and former subordinate of A at Seoul Semiconductor, salary increases of 200% each and new jobs at Everlight Electronics in return for technical data from Seoul Semiconductor.

B and C took out laptops from the company to show secret materials of Seoul Semiconductor to A, and browsed for the secret information using their laptops at home on weekends to avoid suspicion from their colleagues. B and C also took photos of the information and either sent them via SNS or delivered them in person at Everlight Electronics in Taiwan.

In particular, B and C learned that Seoul Semiconductor had filed an injunction lawsuit against A for prohibition of competitive transaction as he joined Everlight Electronics in Taiwan, and used aliases and fake business cards to avoid litigation. They even denied the fact they were under the employ of Everlight Electronics during the investigation.

However, facts of the case showed that B and C were offered twice their previous salaries at Seoul Semiconductor, residence fee, monthly a week-long holidays, and round-trip airfares, etc. from Everlight Electronics.

Seoul Semiconductor invests approximately 10% of its annual sales into development of LED technology. In 2011, it produced automotive LED the first in Korea. As a result of its endeavors, Seoul Semiconductor holds more than 12,000 patents, and has been listed as one of the top companies around the world in terms of Patent Power compiled by IEEE (Institute of Electrical and Electronics Engineers), a global technical professional organization for electronics and electrical based in the USA. Seoul Semiconductor is the fourth largest LED manufacturer globally. The global LED lighting market currently stands at KRW 37 trillion. However forecasts expect the sector to reach KRW 52 trillion moving forward.

Separate from this case, Seoul Semiconductor has filed lawsuits against Everlight Electronics in Taiwan for five LED patent infringements.

“We estimate that, if A, B, and C were not discovered and charged, it would have lost KRW 560 billion in research and development over a seven-year period, and encroached upon its sales which currently stands at KRW 1 trillion per year,” said Yong Tae Lee, compliance department executive vice president of Seoul Semiconductor.

“The Police will leverage all legal procedures to track down suspects who leak and divulge technology overseas, as in this case, even when said suspects flee the country. Also, it will cooperate with relevant authorities to enforce measures that will allow the Police to restrict imports/exports and prohibit entry of personnel from foreign corporations that engage in industrial espionage. Moreover, it will continue to work on recovering financial damages caused by the divulgence of technology,” said the Gyeonggi Nambu Provincial Police Agency.

* As a result of a lawsuit regarding the prohibition on the change of employment, which forbids a person from joining a competitor of his/her former employer for a set period of time (1~2 years) after termination, defendant A was ordered to pay KRW 100 million for violating his Non-competition agreement and joining Everlight Electronics, and a further KRW 2 million per day if A continues employment at Everlight Electronics.
