[問題] QC2.0 專利迴避
目前在工作上遇到專利上的問題，Quick Charger，目前Qualcomm只開放provider，
也就是例如充電器端，其他comcumer，例如手機端的裝置都不開放，如此一來手機端
都被它綁住了，下面是QC2.0的專利的主項，請問如果要做專利迴避，有甚麼方向可思考嗎
1. A circuit comprising:
a power bus for attachment to an external device;
a plurality of signal lines for attachment to the external device;
a plurality of first circuits to sense an electrical configuration on the
signal lines; and
a plurality of second circuits to assert an electrical configuration on
the signal lines,
wherein one of the second circuits asserts an electrical configuration on
the signal lines from among a plurality of electrical configurations when one
of the first circuits senses a predetermined electrical configuration on the
signal lines, whereby a voltage from an external device attached to the
circuit is asserted on the power bus at a voltage level that corresponds to
the electrical configuration that is asserted on the signal lines by said one
of the second circuits.
