隨著錄影帶規格之爭改變了廠商在儲存媒體上的技術發展策略，廠商在光儲存世代採取更開放性的策略思維，透過專利聯盟的方式來取得競爭優勢。因此，本研究試圖描繪出專利聯盟企業發展技術策略時的複雜網絡，透過13項指標進一步瞭解廠商如何取得競爭優勢。廠商技術佈局的資料來源為DVD3C專利聯盟在1986至2008年期間公開的339筆美國專利資料。結果顯示只有Pioneer積極結合外部資源以發展利基技術（共同研發比例為0.05）；LG專注在特殊領域之佈局；Philips與Sony廣泛佈局在DVD技術中的17項技術領域，各自領先4項與5項技術領域，從專利廣度與數量上來看是平台發展策略的代表。

Given the competition for video tape format between two camps, strategies for technology development of storage media have been changed that lead companies to adopt more openness in strategic thinking, so as to gain competitive advantage through patent pool. Therefore, this study intends to outline a complex network of companies in a patent pool in developing technology strategies, in order to understand how companies gain competitive advantage in reference to 13 patent indicators. The information source for companies' technology arrangement is 339 sets of USPTO patent data released by DVD 3C Patent Pool from 1986 to 2008. The finding shows Pioneer is the only company actively organizing external resources in developing niche technology (cooperation rate is 0.05), whereas LG is focused on the arrangement in specific fields, and Philips and Sony have broad arrangements in 17 DVD technology fields, ahead of other companies by 4 and 5 fields, and both of them have become the platform leaders in terms of patent scope and quantity.
