A prosecution investigation shows a South Korean firm's 2.5-generation Code Division Multiple Access (CDMA) technology patents have been transferred to a foreign company’s subsidiary in Korea.

The Seoul Prosecution on Friday announced the result of its investigation into the case filed by the Ministry of Commerce, Industry and Energy against Hyundai Syscom’s alleged illegal overseas sell-off of CDMA technology.

The Prosecution said Hyundai Syscom signed the contract to transfer a complete set of 2.5-generation CDMA technologies with UT Starcom Korea, a local subsidiary of the U.S. UT Starcom for 14 million dollars last April. Under the contract, a total of 2,944 patent technologies have handed over.

However, if UT Starcom Korea is to transfer the technologies to its main office in the United States, it should obtain approval of the Ministry of Science and Technology.

CDMA is the one of the most common technology for mobile telephones both at home and abroad.
