诉状之中,值得观察重点
(1)推测大立光电的诉讼策略,先从台湾开始,告赢后再打国际战。大立光电可能尝试建立诉讼主轴theme,努力使法官陪审团建立 “被告曾经剽窃原告智慧财产权”
的先入为主印象;故于诉状17~19段,大立光电刻意揭露与先进光电科技双方先前在台湾法院进行的民事刑事诉讼;例如:2017年12月,因为先进光电科技不当取得大立光电的商业机密,台湾知识产权法院裁定先进光电科技应赔偿大立光电15.2亿新台币(约合五千万美元),国际媒体报导该判决是有史以来台湾法院针对商业机密相关作出的最大赔偿金额;另外台中地检署检察官已经提起公诉,目前刑事案件审理中。
(2)大立光电透过不同途径,尝试主张较早的侵权通知日notice of infringement date,以便能请求更长期间的损害赔偿past damage,如此尽可能多涵盖自提起US专利诉讼日起回溯6年期间内,被告相关侵权产品的损害赔偿责任:
(i) 侵权通知信函日期:2013年8月曾经发函给HP和先进光电科技,告知侵害 ‘691专利;2019 年3~4月先发侵权通知信函给HP告知多项产品镜头侵权,2019年5月再发函给先进光电科技;另外于2019年8月发函给新钜科技。
(ii) 产品专利标示日期:从 2012年1月开始于产品标示 '518专利号码;从 2013年3月开始于产品标示 ‘691专利号码。
(iii) 专利申请案引用关系日期:先进光电科技的9097860号US专利曾经收到美国专利商标局2015年8月4日发出的核驳通知,其中曾引用 ‘691专利为核驳前案证据。另外,先进光电科技的9729771号US专利曾经收到美国专利商标局2016年11月4日发出的核驳通知,其中曾引用 ’378专利为核驳前案证据。而新钜科技的10007096号US专利曾经收到美国专利商标局2017年6月28日发出的核驳通知,其中曾引用’691专利为核驳前案证据。
(3)如诉状34~35段所述,大立光电除了发出侵权通知信函给HP外,稍后还要求HP确认已经被找到的HP产品中所使用的先进光电科技镜头型号,以及其他已经被找到的HP产品中使用多个镜头的其他镜头供应商资讯;大立光电如此强势对潜在可能客户主张专利权,显见其贯彻智慧财产权保护的决心。
