标题[问题] QC2.0 专利回避
时间Mon May 18 10:12:03 2015
目前在工作上遇到专利上的问题，Quick Charger，目前Qualcomm只开放provider，
也就是例如充电器端，其他comcumer，例如手机端的装置都不开放，如此一来手机端
都被它绑住了，下面是QC2.0的专利的主项，请问如果要做专利回避，有甚麽方向可思考吗
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.
