Interesting, I’ll try and get more information on this one.
NetRatings announced today it has filed patent infringement lawsuits against WhenU.com, Inc. and 180solutions, Inc. as part of the company’s patent enforcement program commenced in early 2005. Under the program, designed to protect the company’s investments in its patented technologies related to the collection, analysis and reporting of computer usage and activity, NetRatings has signed licensing agreements with three companies: Visual Sciences LLC, SageMetrics, Corp., and Omniture, Inc., and has complaints pending against three additional companies: Coremetrics, Inc., Sane Solutions, LLC, and WebSideStory, Inc.
