增強與高通的合作

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）21

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%
