Jury trial starts for Apple, Qualcomm battle

• The San Diego-based jury trial pits Apple (AAPL) and its allies against Qualcomm (QCOM +0.9%) and seeks up to $27B in damages for illegal patent licensing practices.
• The $27B figure represents a tripling of the $9B Apple and friends want, which is possible if the jury finds in Apple's favor regarding antitrust concerns.
• Qualcomm seeks $15B for Apple stopping some of its royalty payments.
• The case, one of many between the former partners, relates to the modem chips that connect devices to wireless data networks.
