In a much anticipated ruling this week, a federal judge found that cellphone chipmaker Qualcomm unlawfully squeezed out rivals and charged excessive royalties to manufacturers such as Apple.
U.S. District Judge Lucy Koh of the Northern District of California issued a 233-page ruling late Tuesday night in favor of the Federal Trade Commission's antitrust allegations and ordered that Qualcomm, which manufactures nearly all the chips in smartphones, must go back and renegotiate its licensing deals.
"It's a decision that has really global effects," said Mike Swift, chief global digital risk correspondent for MLex, a technology and legal publication.
At the crux of this fight and other related fights is Qualcomm's business model and the company's hold on the smartphone market.
Based in San Diego, Qualcomm is the world's largest maker of mobile chips. It created some of the technology integral to cellular networks and holds patents on a range of cellphone technology, including key 3G, 4G and 5G networking components. Because of those patents, all smartphone manufacturers have to pay a licensing fee to Qualcomm, whether they use the company's chips or not.
Qualcomm also has a "no license, no chip" policy, which requires phone manufacturers to pay for an exclusive license in order to buy their chips. Additionally, Qualcomm has refused to license its patents to rival chipmakers. The company has typically set licensing fees at 5% of the price of the mobile device — something Apple took issue with, arguing that features that make a phone more expensive may have nothing to do with Qualcomm's technology.
