科技產業資訊室 (iKnow) - Joy 發表於 2010年7月28日
2010年7月22日,隸屬於日立集團的日立消費型電子產品公司,以八項專利侵權控告平面電視廠商Vizio及其在台灣的代工廠冠捷科技,使得面板產業的戰爭越演越烈。被告之一的冠捷科技曾於今年(2010)4月在加州北部聯邦地院向日立提起專利確認之訴,本次日立的行動是否為報復性控告還有待釐清,全案將由德州東部聯邦地院負責審理調查。

本次的系爭專利共有八項(US5,502,497、US5,534,934、US6,037,995、US6,388,713、US6,549,243、US7,012,769、US7,286,310、US6,144,412),原始專利權人皆為日立集團所有,涉及專利技術應用於平面電視相關之影像圖片的放大、壓縮以及數位化等技術。

Vizio創辦人王蔚(William Wang)自於2002年成立公司,主打平價平面電視,以低價策略和通路銷售在競爭激烈的平面電視市場中殺出一條血路。自2008年開始Vizio打入全美前三大液晶電視品牌,與三星、夏普、索尼等大廠平起平座,甚至2009年曾經登上北美液晶電視龍頭寶座。

專利訴訟策略已成為一種商業競爭手段。近年來索尼、船井及樂金接連以專利訴訟戰圍堵Vizio,使其市場佔有率略有下滑。

而被告者之ㄧ的冠捷科技,目前是中國第一大的液晶顯視器代工廠商,過去一直是Vizio和樂金(LG)的長期合作夥伴。

不管是對於日立、Vizio或冠捷來說,專利法庭的訴訟早已屢見不鮮,也因此這次原告被告的相互角力格外引人注目,同時也由於面板產業的高度競爭,本次的訴訟會否改變市場的板塊分配,值得後續觀察。(461字;表1)
