With so much attention being placed on each and every U.S. patent application that Google has published, I thought it would be interesting to take a quick look and see what others are doing in the way of search-related IP. By NO means should this be considered a complete list. It's far from it. I just did some quick research and came up with the following list of patent applications (most published within the few weeks) from a few of the major search players and a couple of other companies. Each patent is linked to the full text where you can learn more. Lots of interesting stuff going on.

Title: Method and system for identifying image relatedness using link and page layout analysis
Title: Method and system for classifying display pages using summaries
