Qualcomm's legal spat with Apple is growing nastier; the chip giant now claims Apple tried to give rival Intel a sneak peek into Qualcomm's trade secrets. Qualcomm has tried to ban the sale of select iPhones in the U.S., and has also begun an attempt to get iPhone sales banned in China.
Qualcomm said its "modem that could be used in the next generation iPhone has already been fully tested and released to Apple". The legal proceedings between the two companies started in January, when Apple sued Qualcomm, accusing them of overcharging for use of their patented chips.
Rasesh Shah claimed that Qualcomm lied to shareholders when it told them that, "unlike some other companies in the industry that hold back certain key technologies", Qualcomm offers its "entire patent portfolio for use in cellular subscriber devices and cell infrastructure equipment".

Qualcomm's fight with Apple has taken another turn, as the company has filed yet another lawsuit.
