IBM 控告 Amazon 侵犯了五項專利，包括：
US 5,796,967 - Presenting Applications in an Interactive Service.
US 5,442,771 - Storing Data in an Interactive Network.
US 7,072,849 - Presenting Advertising in an Interactive Service.
US 5,446,891 - Adjusting Hypertext Links with Weighted User Goals and Activities.
US 5,319,542 - Ordering Items Using an Electronic Catalogue.
沒有這次新聞，我想也很少有人留意 542 及 771 兩項專利。現今覺得是理所當然的技術，原來也得付專利給大公司。這已不是關乎到是否抄襲或盜用的問題，而是有沒有細心查看現有的專利目錄了。
