Nielsen and comScore have routinely been miles apart on their tracking of the online video industry, which could be surprising in light of a lawsuit filed today by Nielsen that alleges comScore violated five of its patents in collecting, analyzing and reporting online traffic.
The lawsuit was filed in U.S. District Court in Virginia. Nielsen is seeking an injunction against further infringement, damages, and payment of its attorneys' fees.
The Hollywood Reporter says that Nielsen claims comScore's various products infringe upon its patents, including one for a "Computer Use Meter and Analyzer," the same charge Nielsen faced in a lawsuit brought by Jupiter Media Metrix. Nielsen/NetRatings gave Jupiter $15 million for the patents in question in 2002.
