增強與高通的合作

21

WCDMA 專利分布上，以歐美廠商所擁有的專利數量最多，其以InterDigital 、 Nokia 、 Qualcomm 和 Ericsson位居前四大

WCDMA 的核心專利仍多掌握在 Qualcomm 手上，且 Qualcomm 擁有 WCDMA 最重要的核心專利，使得後續極度相關技術很容易觸碰 Qualcomm 的專利

前代通訊專利概況

ETSI （ 2010/02 ）

22

Qualcomm 掌握大量 3G 專利，有豐厚專利授權金，且晶片也多能支援所有的機作業系統平台，現階段已涵蓋多數國際手機品牌客戶，使得 Qualcomm 在手機基頻晶片市場一直居於領導地位 QTL （ Qualcomm Technology Licensing ）是

Qualcomm 專門處理專利授權的單位，其處理的專利技術涵蓋WCDMA 、 CDMA 、 GSM/GPRS/EDGE 和 OFDMA等標準及這些技術的衍生性商品 QTL 單位的營收主要來自於授權費和權利金的收取，根據 Qualcomm 財報， 2010 年 QTL 營收為

36.59 億美元，佔Qualcomm 整體營收的 33.3%
