Google is possibly most well known for the patenting of an algorithm that sorted and ordered search results based upon a metric known as PageRank, named after Google Co-Founder Lawrence Page, while he was a student at Stanford University. Yahoo started off as a Web Directory, which became a Search Engine, and the patent it might be most well known for is one that it purchased from Overture (Originally Goto.com), and successfully sued Google with (winning a settlement out of the litigation) which describes paid search. That patent appears to have been assigned by Yahoo, along with a number of other patents last month.
A couple of weeks ago, an article on Yahoo’s patent portfolio ran, and provided some insights into what value those patents might hold. The article, Yahoo Has a Strong Patent Portfolio, But Reported Valuation is Too High gives us some ideas regarding how much the Search Engine’s patents might be worth (4 Billion?), and what they’ve been doing with them. Has Yahoo sold a good amount of those patents not much less than a week after that article? We don’t know for certain. It’s possible that they may have to one of the remaining bidders for the company: Exclusive: Yahoo’s bidder shortlist points to cash deal -sources.
On April 18th, 2016 an assignment was recorded at the United States Patent and Trademark Office (USPTO) on a transaction that appears to have been executed on April 18th, 2016 involving the assignment of 2648 patents from Yahoo! Inc. to Excalibur IP, LLC. It’s possible that name is made up to hold the patents temporarily. The address that the assignment indicates is Excalibur’s is “701 FIRST AVENUE SUNNYVALE, CALIFORNIA UNITED STATES OF AMERICA 94089”. A search for that address points to the headquarters of Yahoo! as we see in the knowledge panel below, so the actual purchaser appears unknown.
