SAN DIEGO, CA (Feb. 23, 2006)—WebSideStory, Inc. (Nasdaq: WSSI), a leading provider of on-demand digital marketing applications, today announced that it filed a patent infringement lawsuit against NetRatings, Inc., in the U.S. District Court for the Southern District of California. WebSideStory alleges that NetRatings infringes WebSideStory’s patent rights.

“We believe this action is necessary to protect the intellectual capital we have worked hard to develop in-house since 1996,” said Jeff Lunsford, chairman and CEO of WebSideStory. “Although we have been focused on innovation and building value for our customers, we cannot ignore companies that we believe are infringing our intellectual property.”

In its complaint against NetRatings, WebSideStory is seeking unspecified monetary damages and an injunction against further infringement by NetRatings.
