微軟的專利追蹤網站

新聞來自:http://microsoft-news.com/microsoft-launches-patent-tracker-showing-its-commitment-to-patent-transparency/

微軟自己發布一個Patent Tracker的專利檢索網頁,針對微軟自己的專利提供大眾進行檢索,其實專利的檢索工具眾多,為何微軟要自己出個專利檢索頁?可以想像的是,微軟透過自己的檢索服務主動讓他人知道自己的專利的佈局廣及全世界,宣示自己是專利強權,也能避免不必要干擾。
當然網站更包括有其他智慧財產的型態,除專利以外,更有商標、著作權、授權資訊...等。

專利部份,有個檢索欄位,不過僅能找到資料,卻沒有閱讀資料的功能,這當然可以再去google找就是了:



我試著鍵入最近公告的一件專利案US8375221,這件專利涉及在ARM處理器架構下的韌體認證的平台模組,這件專利技術是在韌體方法植入安全程式碼(secure code),透過韌體方式避免系統接受過多其他作業環境而導致有安全漏洞。一般電腦系統中有個在進入作業系統前的前置開機程序中啟動一種韌體為基礎的信任平台模組(fTPM),其中的韌體碼會被讀入系統的記憶體中,因此可以透過其中韌體程式來控制系統執行的作業環境。

專利範圍獨立項界定如何利用fTPM載入系統安全功能的方法。

1. A method for enabling a trusted execution environment (TrEE) in computing devices without a hardware trusted platform module (TPM) component, comprising steps for:
retrieving an fTPM (firmware-based TPM) software module from a firmware component of a computing device, said fTPM providing a software-based interface to security extension functionality integral to one or more processors in the computing device;
retrieving a software-based Monitor module from the firmware component of the computing device;
instantiating the fTPM and the Monitor into a Secure World environment within protected memory of the computing device prior to booting an operating system (OS) on the computing device;
wherein one or more of the processors use an ARM (advanced RISC machine)-based processor architecture, and wherein the security extension functionality integral to the ARM-based processors includes TrustZone-type security extensions and security primitives that are used by fTPM following instantiation of the fTPM; and
enabling a TrEE on the computing device by allowing a Caller in a Normal World environment to access the security functionality of the one or more processors via a Secure Monitor Call to the Monitor, said Monitor then passing instructions relating to the Secure Monitor Call to the fTPM in the Secure World.

這個技術似乎可以連結到最近一個新聞,西班牙開放原始碼社群在歐洲對微軟提出反托辣斯告訴,原因是微軟透過韌體的修正不讓Linux等其他作業系統安裝到微軟Windows8裝置內,這可能是透過此件專利技術達成的!

商標部份也很精彩,可以看到微軟取得的各種商標權:



對於軟體公司而言,著作權相對重要:
