Looks like all this Adwords litigation against Google isn’t going away anytime soon.  And why should it: everyone wants a slice of the online advertising pie.  Yesterday, a group of Texas plaintiffs filed a massive trademark infringement suit against Google, alleging that its practice of selling trademarked adwords to competitors of the trademark owner is illegal.

While the complaint, is directed at AOL, Turner Broadcasting, Myspace, and Ask.com, Google is clearly the big fish in the pond.   While there have been  lawsuits against Google on this front (Rescucom v. Google being the most notable), a class action suit definitely ups the ante.   If this suit succeeds, it could take a huge bite out of Google’s revenue stream and make things more difficult internally for selling adwords.  Eric Goldman has more analysis on the procedural side of things.
