L90 sues DoubleClick

Published on .

Ad-serving company and ad network L90, Los Angeles, filed suit against rival DoubleClick, New York, in the U.S. District Court for the Southern District of New York. The lawsuit against DoubleClick alleges unfair business practices, including fraudulent procurement and unlawful assertion of its recently issued U.S. patent for ad-serving technology. The suit seeks an order from the court enjoining DoubleClick's unlawful conduct and awarding L90 monetary and punitive damages. The lawsuit also asks for the court's declaration that DoubleClick's patent is invalid and unenforceable. Elizabeth Wang, VP-general counsel at DoubleClick, responded: "L90's counterclaims are desperate, baseless and clearly retaliatory. This suit is clearly in response to our suit against L90 for infringement of our patent."
