2012年12月21日,韓國Samsung Electronics Co., Ltd.公司及其美國分公司Smasung Telecommincations America, LLC (下稱Samsung),向美國國際貿易委員會(the United States International Trade Commission, ITC)提告,請求ITC調查瑞典通訊設備商Telefonaktiebolaget LM Ericsson及其美國分公司Ericsson Inc.(下稱Ericsson),其製造並輸入美國販賣使用的LTE無線通訊系統與使用於該系統中的設備產品,例如Ericsson的RS 6000基地台(RS 6000 series base stations)產品,就Samsung所擁有之7項專利權利構成侵權,進而違反美國關稅法第337條(19 U.S.C. § 1337)之規定。

這又是一場通訊標準必要專利(SEP)之授權費的糾紛。Samsung指控索取的專利授權費過高,造成不公平競爭。Ericsson認為,三星電子試圖大幅降低其應繳納的標準必要專利的授權費,這將使獲得Ericsson專利授權的其他企業在與三星競爭時處於不公平的劣勢。

本案系爭專利中有4項為Samsung向標準制訂組織ETSI所揭露之LTE無線通訊技術標準的標準必要專利,包括美國專利編號US 7,782,749(‘749專利,對應到3GPP TS 36.211 v.8.5.0)、US 8,165,081(‘081專利,對應到3GPP TS 36.212 v.8.5.0與3GPP TS 36.213 v.8.5.0)、US 8,208,438(‘438專利,對應到3GPP TS 36.211 v.8.5.0)與US 8,228,827(‘827專利,對應到3GPP TS 36.212 v.8.5.0與3GPP TS 36.300 v.8.5.0)。

本案兩造當事人在2001年12月18日,就各自所擁有、無線通訊協定相關之專利組合簽訂第一次交互授權協議,該協議於2005年12月31日到期;而後兩造又在2007年6月29日簽訂第二次交互授權協議,該協議則是在2011年3月31日到期。

在第一次協議到期後,Samsung向ITC提告,請求調查Ericsson無線通訊設備產品侵害其專利權利(案號為Inv. No. 337-TA-577),而Ericsson亦向ITC提告,請求調查Samsung無線通訊裝置產品侵害其專利權利(案號為Inv. No. 337-TA-583),兩案分別在2007年8月29日與8月21日,因兩造和解而終止調查。當時Ericsson亦向美國德州東區聯邦地院提起兩起專利侵權告訴(案號為2:06-cv-00063-TJW與2:06-cv-00306-TJW),控告三星侵權,而亦是在2007年與三星再度締結授權契約後撤銷訴訟。

而在第二次協議到期後,歷經協商未果,Ericsson再度向ITC提告,請求調查Samsung的消費電子裝置產品、包括無線通訊裝置、平板電腦等侵害Ericsson所擁有之專利權利(案號為Inv. No.337-TA-862),並亦向德州東區聯邦地院提起兩起專利侵權訴訟(案號為6:12-cv-00894-LED與6:12-cv-00895-LED)。而Samsung的反擊,除提起本案調查請求外,亦在前述Ericsson所起訴之專利侵權訴訟中提起專利侵權反訴,而在該反訴中有關本案7項系爭專利之主張,被法院裁定另案審理,並在本案調查進行期間中止審理程序(另案審理後之案號為6:13-cv-00364-LED)。

本案7項系爭專利內容如下:

  • ‘749專利,名稱為「用來映射實體下位控制通道到資源與裝置、藉以在無線通訊系統中傳輸/接收經映射之實體下位控制通道的方法(Method for mapping physical downlink control channel to resources and apparatus for transmitting/receiving the mapped physical downlink control channel in a wireless communication system)」,於2010年8月24日核發,包括6個獨立項與8個附屬項,Samsung主張其請求項1至13受到侵害;

  • 美國專利編號US 6,617,929,名稱為「Doherty微波功率放大器之全輸出匹配裝置(Full output matching apparatus of a microwave doherty amplifier)」,於2003年9月9日核發,包括2個獨立項與6個附屬項,Samsung主張其請求項1至8受到侵害;
  • 美國專利編號US 6,767,813,名稱為「具備擴充有效寬度之有效作用區域的積體電路裝置及其製造方法(Integrated circuit devices having active regions with expanded effective widths and methods of manufacturing same)」,於2004年7月27日核發,包括4個獨立項與20個附屬項,Samsung主張其請求項1至3、5至12與14至23受到侵害;
  • 美國專利編號US 6,865,682,名稱為「具備整合電壓調節器之微處理器模組(Microprocessor module with integrated voltage regulators)」,於2005年3月8日核發,包括1個獨立項與8個附屬項,Samsung主張其請求項1、2、4與8受到侵害。(1431字;表2)
