從美國ITC網站獲知，SPH America於2009年3月25日對日本京瓷(Kyocera)、美國MetroPCS及Sprint Nextel提出ITC 337調查請求，指出被告廠商所生產的無線通信裝置(wireless communications devices and components)，已侵犯了SPH America所擁有的2件美國專利：US RE40,385 and US 5,960,029。SPH America提出被告產品進口至美國銷售之禁制令。
SPH America指出提告原因之一是該2件爭議專利之再授權〈Sublicense〉問題而產生。SPH認為京瓷技術侵權並製造其產品後，進口至美國由MetroPCS公司銷售，所以連同向MetroPCS提出告訴。Sprint Nextel也是因進口三洋(Sanyo)侵權的產品在美國銷售，而被連環告。
美國SPH America 為ETRI衍生專利之專屬授權公司。ETRI是韓國政府資助成立的研究機構電子通訊研究院（Electronics and Telecommunications Research Institute, ETRI），該2件美國專利：US RE40,385 and US 5,960,029，也是屬於ETRI所研發而取得的專利，專屬授權予SPH America使用。
事實上，SPH America利用這2件專利，已打過多次訴訟戰了。除可參考本網站前期文章【韓國專利策略出國打仗去，ETRI在美控告HTC侵權啟示】之外，我們也調查一下SPH America的相關3G通信的訴訟案，整理如下表，請參考。
