An FTC official, speaking to The Korea Times, had this to say on the matter:
Qualcomm has been collecting royalties from manufacturers on a per-product basis, calculating the fees based on the value of the whole product, rather than only on the used Qualcomm-patented parts. The company has been collecting some $1.27 million annually from manufacturers such as LG and Samsung. Last year, Qualcomm faced a similar $1 billion fine after an anti-trust dispute in China.
