Google has released four new document patent applications. All four are on the topic of scoring a document. One is based on scoring documents on query analysis, an other on traffic analysis, an other on link criteria and the last is on age of the document.

• Document Scoring Based on Query Analysis
• Document Scoring Based on Traffic Associated with a Document
• Document Scoring Based on Link-Based Criteria
• Document Scoring Based on Document Inception Date

These four patent applications were released in the past two weeks. Even Matt Cutts is named on one.
