Apple parts firms sued

Qualcomm has filed a complaint against Foxconn Technology and three other Apple contract manufacturers for not paying royalties, firing the latest salvo in its fight with the iPhone maker.

The other manufacturers listed by Qualcomm were Pegatron, Wistron and Compal Electronics.

Apple sued Qualcomm in January, accusing it of overcharging for chips and refusing to pay some $1bn (€906m) in promised rebates.
