Google's PageRank Patent

之前In Re Bilski判例下來,是不是以前核准的軟體專利就岌岌可危?

其實所謂的「machine or transformation test」,從字面來看,並非十分清楚,從個例子來看,或許單純使用電腦執行特定軟體,並非滿足此「聯繫特定機器」的條件,是否軟體程式能夠有任何「轉換」,也是可以透過例子幫助瞭解!

Google專利US
6,285,999
Claim1:
1. A computer implemented method of scoring a plurality of linked documents, comprising:
obtaining a plurality of documents, at least some of the documents being linked documents, at least some of the documents being linking documents, and at least some of the documents being both linked documents and linking documents, each of the linked documents being pointed to by a link in one or more of the linking documents;
assigning a score to each of the linked documents based on scores of the one or more linking documents and
processing the linked documents according to their scores.

該發明的步驟有:
取得複數個文件,其中具有被連結的文件與連結別的文件的文件;
指定各文件分數;
根據分數處理該文件。

這就是Google現行如何判斷檢索順序的技術,但是否有tied to a particular machine,或是產生任何physical transformation?
即使Claim 1前言提到「computer implemented」 method,但電腦是台machine,但應非「particular machine」,各元件亦明顯是由軟體程式達成,並無任何硬體機器的關聯!
是否有物理上的轉換,各步驟最後形成的目的是將文件排行,亦非有任何「轉換」

對此machine or transformation test算是有點初步瞭解了
