Internet security software vendor—Precedent-setting federal case

In a precedent-setting case, we represented a vendor of Internet security software that had been sued by an adware company for blocking pop-up ads and adware. A federal court dismissed the claims, holding that our client was immune from civil liability under the Communications Decency Act. 47 USC § 230(c)(2)(B). The United States Court of Appeals for the Ninth Circuit affirmed the district court's ruling. See Zango, Inc. v. Kaspersky Lab., Inc. (9th Cir. Case No. 07-35800). The case set precedent as the first application of the Act to immunize a vendor of Internet security software used to screen adware and spyware.
