Apple's lawsuit retaliation continued on Friday after it sued Motorola in the US over 3G patent issues. The iPhone designer sought to block Motorola from making patent violation accusations based on its use of Qualcomm's MDM6610 cellular chipset as well as any others it might use. It came after Qualcomm confirmed to Apple that it was already paying for a license to Motorola's 3G patents, which Apple took to mean that it was exempt from paying itself.
