So say American film society to sue fast thunder can additional purposeful, these year western country always censures China in intellectual property domain, because,force of fire of before a few years of Zhuhai is sued by SIGMATEL of provider of American MP3 chip also is intellectual property, the swift and violent development that real reason is Zhuhai fire force truly has browbeaten SIGMATEL, the intellectual property case that SIGMATEL prosecutes Zhuhai fire force also is absent MP3, and in domain of power source power comsumption, allegedly the period of time of to lodge a complaint, the client of force of many Zhuhai fire converts SIGMATEL, because,very simple everybody does not consider the matter the lawsuit ask for trouble of Zhuhai fire force, this just also is the real reason that SIGMATEL sues Zhuhai fire force, do sth over and over again prosecution of two years is Zhuhai fire force as a result eventually most reconcile in both sides of Shenzhen countercharge SIGMATEL, the judgement that the market share of force of final Zhuhai fire exceeds SIGMATEL to became the MP3 chip provider with the greatest whole world to also prove SIGMATEL is original and be anxious.

这么说来美国电影协会起诉迅雷只能另有目的，这些年西方国家总是在知识产权领域指责中国，前几年珠海炬力被美国MP3芯片提供商SIGMATEL起诉也是因为知识产权，真正的原因确是珠海炬力的迅猛发展已经威胁到SIGMATEL，SIGMATEL起诉珠海炬力的知识产权案也不在MP3，而在电源功耗领域，据说提起诉讼的一段时间，大量珠海炬力的客户都转投SIGMATEL，原因很简单大家都不想因为珠海炬力的官司惹火上身，这也才是SIGMATEL起诉珠海炬力的真正原因，折腾了两年的起诉最终结果是珠海炬力在深圳反诉SIGMATEL双方和解，最后珠海炬力的市场份额超过SIGMATEL成为全球最大的MP3芯片提供商也证实了SIGMATEL最初的判定和担忧。
