Apple seeks a bigger bite of mobile market

Apple is piling onto lawsuits that attack the way Qualcomm licenses technology for mobile phones in a widespread effort to rake back profits in a slowing market.

The latest suit by Apple, which it filed last week, alleges that Qualcomm has unfairly used the power of its patents, which cover the fundamentals of phone systems, and its chip business to prop up its dominant position in the industry.

Apple’s legal actions follow regulatory investigations and fines on three continents, including a lawsuit announced last week by the US Federal Trade Commission.
