Modavox has claimed that Tacoda violated its patent on a “Method and System for Adding Function to a Web Page,” ClickZ reports.
"There is speculation that Tacoda's pending acquisition by AOL could have triggered the patent infringement suit. The patent is said to cover technologies that serve customized multimedia content and advertising to its users. The patent was filed for in 1999 and given to Modavox in 2003 while it was operating under the name SurfNet Media Group.
Nathaniel Bradley, CTO and chief product officer of Modavox stated, “We really focused on Tacoda a long time ago when they came out with their whole business model. Tacoda is one of many potential infringers out there. It's impossible for us to sue everybody.” Other competitors he mentioned were AlmondNet and Revenue Science," ClickZ reported.
