Nov 19 (Reuters) - South Korea's antitrust regulator is

investigating the Seoul offices of Arm Holdings

as part of ongoing scrutiny of the company's licensing

practices, a person familiar with the matter told Reuters on

Wednesday.

Bloomberg News reported earlier that South Korea's Fair

Trade Commission visited Arm's Seoul office, following a

complaint from Qualcomm ( QCOM ) alleging that the British

semiconductor and software design company is restricting access

to its technology and harming competition after more than 20

years of operating an open network.

Arm and Qualcomm ( QCOM ) did not immediately respond to Reuters'

requests for a comment. The FTC declined to comment.
