In the roughly 90 patents they applied for on November 2, 2006, Microsoft reveals that it is apparently pushing its research in the search engine market.

I had a look through all the search related patents. There is stuff to detect duplicate content, spam and context sensitive search. Nothing much that is revolutionary though. I put up an analysis on my website.
