據Strategy Analytics觀察統計2008年全球手機出貨量達11.78億支，但從2008第四季起手機成長已呈現負成長之勢。台灣過去素有「手機代工王國」的美譽， 2008年手機整體出貨量終於突破1億支，全球市占率也衝上13.8%。隨著智慧型手機市場需求放大，MIC估計2008年，台灣PDA手機出貨量約1200萬台，成長21.6%，以全球市場規模1700萬台計算，台灣PDA手機供貨量占全球高達七成。
全球通信技術發展快速，且技術都集中在美歐大廠手中，而手機代工幾乎是通信技術的後端應用之ㄧ環而已，極易陷入專利侵權或付出高額技術權利金，反而稀釋了台灣廠商之利益。台灣業者應該充分掌握住國際間專利訴訟資訊，避開大砲專利，降低威脅風險。
本調查以Stanford Law School所收錄聯邦地方法院訴訟資料為基礎，統計期間自2000年1月1日至2008年12月31日，全球各廠商提告有關通信類專利訴訟案件(US Patent Class 455: TELECOMMUNICATIONS)，查得共計242案件，涉及爭議專利或訴訟引用專利數328個，如圖一。該通信類美國專利分類USP Class 455，參見表一：範圍說明。
