Google patents now on CD

Ever wonder what Google is up to? Well, an expert on the search engine has something that should provide some clues. Stephen Arnold, author of "The Google Legacy," is selling for $50 a CD-ROM containing the more than 120 patents he believes Google and its employees have been assigned.

"Among the important patents included in this collection are the Google patent for individualizing search results, the patent for the use of time as a factor in PageRank relevance, and a 'de-duplication' patent for eliminating redundancy," Arnold wrote in a statement. "Each of these patents underscores Google's technology for delivering specific results to particular users and for improving the quality and usefulness of results displayed in response to a user's query."
