近年來亞馬遜公司在商業發展上引領前沿，作為一家因為成功發展電子商務平台而成為全球頂尖的國際企業，亞馬遜公司並沒有止步於前，在站穩原有的商業發展後，開始涉足於其他領域，營運範圍從電子商務、雲端運算拓展至電子閱讀產品、無人超商、智慧語音產品等。營運的擴張需要以技術為基礎，亞馬遜公司究竟在技術上下了麼功夫？其技術策略是否逐步演進？為回答這些問題，本研究從專利之角度，探討亞馬遜公司發展過程中在技術策略上的變化。
本研究透過全球專利資訊網WEBPAT搜集亞馬遜公司已核准之發明專利，從2006年到2021年4月15日共得14,047筆，其中又篩選出具有引證連結性的專利7,516筆專利，以此作為主要研究對象。本研究根據此7,516件專利進行主路徑分析，觀察亞馬遜公司專利技術的主要發展軌跡，接著，藉由將專利引證網路加以分群，探討前十五大集群專利技術，挖掘更深入之技術發展輪廓；最後，透過技術生命週期、IPC國際專利分類、技術多樣性、集群與商業應用分析亞馬遜公司技術策略的變化。
研究結果顯示，亞馬遜公司專利技術主要以支撐其現階段的商業發展模式電子商務和雲端運算服務的技術發展為主；同時，其發展技術亦有著眼於支持營運創新，例如在十五大集群專利內容包括應用於無人超商、電子閱讀產品、智慧語音產品等專利技術，而這些技術目前仍處於成長期，未來將持續發展，特別是集群技術特徵為物品資訊的識別技術，其成長趨勢從2015年後迅速增加，此技術主要應用於無人超商。未來亞馬遜公司專利技術發展將持續呈現多種技術並行的發展方向。

In recent years, Amazon has been at the forefront of business development. As an international company that has become one of the world's leader. Although the company has succeeded in developing e-commerce platforms, it has not stopped there, but has started venturing into other areas. The expansion of its operations needs to be underpinned by technology. So how much has Amazon invested in technology? Was its strategy keep evolving? To answer these questions, by intensive patent analysis, are we able to conduct this study and provide our observation on the changes in Amazon's technology strategy.
The study uses WEBPAT, a global patent information network, to collect a total of 14,047 patents released by Amazon from 2006 to April 15, 2021, of which 7,516 patents were selected as the main target. Afterwards, the majority of the analysis was conducted based on these 7,516 patents, from which the observation on development trajectory of Amazons patented technologies is presented. Finally, the changes in Amazon's technology strategy through technology lifecycle, IPC international patent classification, technology diversity, clusters and business applications are analyzed.
The results of the study show that Amazon’s patented technologies mainly target at the development of its current business model of e-commerce and cloud computing services; at the same time, its technology development also focuses on supporting operational innovation. That is obvious when we investigate on the 15 major patent clusters, among which are some particular high-end patented technologies included, such as unmanned superstore, e-reading products and intelligent voice products. These technologies are still in their growth phase and will continue to be developed in the future. In particular, the cluster, which features the technology of object recognition, has been grown rapidly since 2015. This technology is mainly used in unmanned supermarkets. The future development of Amazon's proprietary technologies will continue with a concurrent, multiple-path pattern.
