Apple face iPhone ban in USA in legal fight with Qualcomm

Apple and Qualcomm have been fighting patent violation legal suites in many regions across the globe. This week, US International Trade Commission would recommend a ban on affected iPhones from sale in USA. The ruling came in one of the two cases and the second case ruling came out in Apple’s favour.

Judge Mary Joan McNamara has recommended banning iPhone models that violated Qualcomm’s patents. This applies to models from iPhone 7 till iPhone XS that are powered by Apple A10, A11, A11X and A12 chipsets. These chipsets are powered by Intel models and violate
US Patent No. 8,063,674 patent related to power management. Panel will decide on action to take by end of July. We do not think there is a need to worry as it is not that easy to ban iPhone in their home country.

Patent Abstract

A multiple supply voltage device includes an input/output (I/O) network operative at a first supply voltage, a core network coupled to the I/O network and operative at a second supply voltage, and a power-on-control (POC) network coupled to the I/O network and the core network. The POC network is configured to transmit a POC signal to the I/O network and includes an adjustable current power up/down detector configured to detect a power state of the core network. The POC network also includes processing circuitry coupled to the adjustable current power up/down detector and configured to process the power state into the POC signal, and one or more feedback circuits. For reducing the leakage current while also improving the power-up/down detection speed, the feedback circuit(s) are coupled to the adjustable current power up/down detector and configured to provide feedback signals to adjust a current capacity of the adjustable current power up/down detector.
