Gary posted a blog entry named A Look at Some Non-Google U.S. Patent Applications from Yahoo, Microsoft and Others
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.
Enough Google talk, what do you think of these patent apps by HP, Microsoft, Yahoo!, and Oveture (yahoo owned)?
