Oct 23rd - Qualcomm (QCOM.US) fell more than 4% to $165.4 before market opening. On the news front, the battle between Qualcomm and chip design company Arm escalated, as Arm revoked a license allowing long-term partner Qualcomm to use Arm intellectual property to design chips, leading to an escalation of legal disputes around key smart phone technologies. It is reported that ARM has given Qualcomm a 60-day notice, planning to cancel their architecture license agreement. This means Qualcomm will not be able to develop its own chips based on the standards owned by ARM. Most Android smart phones use Qualcomm's technology, and if the agreement is canceled, Qualcomm may need to stop selling products that account for a large portion of its revenue, facing massive losses.
