科技產業資訊室 (iKnow) - Michael 發表於 2015年7月9日
Broadqast Solutions, LLC於2015年6月23日向美國德州東區聯邦地方法院同時控告戴爾(Dell)在內的二十二家廠商侵權。
原告是剛於今年(2015)三月於德州成立之公司,主要業務為消費性電子和個人電腦、無線通信裝置、網路和半導體產品;參照表四,被告分為兩群:
  • 第一群為包括東芝(Toshiba)在內的八家廠商,原告主張該些廠商侵害原告美國第8,290,035號專利的請求項1及美國第8,065,594號專利的請求項1,亦就是該些廠商的發射機產品侵害原告上開專利有關發射機的請求項;
  • 第二群為包括戴爾和LG在內的十四家廠商,原告主張該些廠商侵害原告美國第8,290,035號專利的請求項17及美國第8,649,429號專利的請求項7,亦就是該些廠商的接收機產品侵害原告上開專利有關接收機的請求項。
原告所主張受侵害之系爭專利共有三件,發明人皆為Limberg Allen Leroy,並皆由發明人輾轉讓與給Broadqast Solutions, LLC,並旋即提出本案訴訟。分別:
  • 美國第8,065,594號專利「8VSB DTV signals with PCCC and subsequent trellis coding」,2011年11月22日公告獲准,申請號US11/986,940,申請日2007年11月27日,優先權日2007年6月29日,共有21項專利請求項(第1、8及20項為獨立項) ,使用於通過在空間之中播送於特定殘留邊帶數位電視廣播信號中發送輔助資料之方法,優點為該方法避免了限制代碼字的長度之需求,以便使每個代碼字準確地符合於一相應的有效資料淨荷段的184個字元寬度之內,該方法決定在允許所發送碼字恢復資料之渦輪解碼過程中之迭代;
  • 美國第8,290,035號專利「Systems for reducing adverse effects of deep fades in DTV signals designed for mobile reception」,2012年10月16日公告獲准,申請號US12/218,131,申請日2008年7月11日,優先權日2007年7月11日,共有19項專利請求項(第1、6、10及17項為獨立項) ,使用於通過機動車輛中接收設備接收數位電視廣播信號,優點為在渦輪解碼之軟式決策的處理中允許使用交錯播放接收的複雜方法;
  • 美國第8,649,429號專利「Systems for reducing adverse effects of deep fades in DTV signals designed for mobile reception」,2014年2月11日公告獲准,申請號US13/619,054,申請日2012年9月10日,優先權日2007年7月11日,共有9項專利請求項(第1、6及7項為獨立項) ,使用於以殘留邊帶調幅(VSB AM)用於傳送數位電視廣播信號之發送設備,優點為發射機的效率和信號傳輸品質可以獲得改善,先進的殘留邊帶( AVSB)調幅系統的解碼性能可以通過降低先進的殘留邊帶( AVSB)調幅系統的信噪比獲得改善,於渦輪碼的解碼期間內接收機所消耗的功率可以減少,從而改進接收機記憶體中渦輪解碼的性能。 
系爭專利領域涉及用於數位電視廣播之應用的關鍵技術;並和殘留邊帶(AVSB)調幅系統相關,原告將系爭專利之請求項分成兩組,針對使用相關技術之發射機和接收機,分別控告不同的廠商,但系爭專利未經法院攻防驗證其有效性,且亦未經過如再發證(Reissue)等補強,而原告選擇同時控告如此多廠商,花費如此大成本,可確定的是原告對系爭專利應該深具信心,但被告都是身經百戰的大公司,結果是否能如原告所願,值得觀察!(1500字;表4)
