Apart from Google, Softlayer Technologies, CitiWare Technology Solutions, Yahoo!, MySpace, Amazon.com, PayPal, Match.com, AOL and the CME Group were named as defendants.
In the suit, various versions of the kernel, from the 2.4.22.x tree to version 2.6.31.x or versions beyond were named as allegedly infringing the patent in question.
Bedrock's suit concerned US Patent 5,893,120 on "methods and apparatus for information storage and retrieval using a hashing technique with external chaining and on-the-fly removal of expired data".
IP activist Florian Mueller said some of the other defendants were "small entities based in Eastern Texas who may have been named primarily for the purpose of keeping the entire case in that particular court district. It appears that the allegations against Google were the first ones in this suit to go to on trial."
Mueller, who analysed the verdict on his blog, added: :The problem is that Bedrock is now in a pretty strong position to collect royalties from other Linux users, especially those utilizing (sic) Linux for large server operations."
Google claimed in its defence that the patent was invalid. Red Hat has also attempted to get the patent invalidated as several of the defendants are among its customers but failed.
