Microsoft 不能在美國賣 Word

這讓我們再次發現 software patent 的有趣之處…

本週軟體業界的大事就是美國德州法院宣判 M$ 的 Word 侵犯了 i4i 的某專利 (5787449Method and system for manipulating the architecture and the content of a document separately from each other),判罰 2.9 億美金,並限制 60 天後不准再賣;另一則比較不那麼受到注意的消息是,上星期 M$ 拿到了一個專利 (7571169Word-processing document stored in a single XML file that may be manipulated by applications that understand XML)…

先看第一條,為什麼 M$ 不能再賣 Word 了呢 ? 坊間有個謠傳是說 i4i 告 M$ 的理由是因為 Word 可以讀寫 XML,其實這是一個誤會,i4i 告的理由其實是 Word 裡面的一個叫做 Custom XML 的功能,簡單地說就是可以讓使用者利用 XML 來擴充 .docx 這個文件格式。就我看來,第二條反而才是比較 危險 的;怎麼說呢 ? 來看一下該專利的 abstract 寫些什麼吧…

A word processor including a native XML file format is provided. The well formed XML file fully represents the word-processor document, and fully supports 100% of word-processor’s rich formatting. There are no feature losses when saving the word-processor documents as XML. A published XSD file defines all the rules behind the word-processor’s XML file format. Hints may be provided within the XML associated files providing applications that understand XML a shortcut to understanding some of the features provided by the word-processor. The word-processing document is stored in a single XML file. Additionally, manipulation of word-processing documents may be done on computing devices that do not include the word-processor itself.

看起來有點像是唱片跳針,不過我覺得其實它就是用一個比較不直覺的方法來描述 用 XML 來當做文件儲存格式 這個東西,例如像是 OpenOfficeODF 之類的東西…

身為一個 Open Source 的支持者,對於 software patent 這種東西,我一向是抱持拒絕的態度;對 software patent 有興趣的人可以參考一下 wikipedia 上面的這三篇:software patentsoftware patent debatesoftware patents and free software

恩恩,不但如此,欧洲版的价钱比美国版的贵。中国版最便宜。
