Loren over at Search Engine Journal points us to a post on SEO by the Sea by Bill Slawski that does an impressive job of listing some of the patents held or applied for by companies Google has acquired over the years like Urchin, Applied Semantics, and Kaltix. Nice work.
It's understandable with Google just being Google, that every patent application they have published or every patent they're awarded gets big attention. However, it's still important to look at what other players are doing in developing in the patent world.
I've been tracking search related patents from Google and others for years, first on my ResourceShelfPLUS site (if you feel like looking back at patents from 2003 and 2004, the page is still live) and lately here on SEW Blog. Below are links to some posts from the past year that look at recently awarded patents or just published patent apps from Yahoo, Microsoft, and many others like IBM and Xerox. One thing is for sure, the folks at the Googleplex are keeping track of what their competition is up to. Are you aware of some of the IP other companies are patenting?
