我們公司有一個蠻好的政策就是會幫晚上留下加班的員工訂便當，並且設立一個娛樂室可以讓大家在那邊吃飯或是看電視。我又是_公司 _的新人，所以天天都留下來加班，今天晚上吃飯的時候，跟隔壁的同事聊天，才知道原來他負責的是『專利工程師』（英文～～ 我就不知道）。
| 今天聽Dr. Jay Kuo演講關於H.264的東西（詳細演講稿記錄我放在延伸閱讀裡面～）或許在軟體公司很注重開發時間的催促下，很多專利權的保護可能沒有人會注意到，最近去[对牛乱弹琴 | Playin’ with IT](http://www.donews.net/keso/) 則看到一些很有趣的新聞 |
IBM最自豪的一件事之一是它在2003年註冊了3415項專利，打破了單一年度獲得專利的紀錄，並連續第11年成爲全球最忙於開發企業知識産權的公司。 > >
這篇文章是從英國《金融時報》丹·羅伯茨(Dan Roberts)的最新文章《IBM的新思路》。大家可以看看～～</p
