Lavandeira v. Infuse, LLC [1]

Celebrity gossip blogger Mario Lavandeira (aka Perez Hilton), who operates the blog perezhilton.com [2], sued Infuse LLC, Margie E. Rogers and Elizabeth Silver-Fagan, the owner, editor and publisher, respectively, of a rival celebrity blog named PerezRevenge.com, which describes itself as a "website where celebrities could post information about their careers, events and when necessary personal lives without the taint of rumor or speculation." Hilton's complaint [3] asserts that their use of the name PerezRevenge is a violation of the Anti-Cybersquatting Consumer Protection Act, as well as unfair competition, federal dilution of trademark, and unfair trade practices.

Hilton seeks injunctive relief and treble damages.

On July 22, 2008, one day after Lavandiera filed his lawsuit, defendant Silver, the publisher of PerezRevenge.com, filed a breach of contract lawsuit against Lavandiera in New York. See the related lawsuit, Silver v. Lavandiera [4].

UPDATE:

05/06/09 - The court, after awarding a default judgment for Hilton, enjoined Infuse [5] from "using the domain name perezhilton.com... [or] using the term 'Perez' to designate any platform...that contains entertainment or celebrity news or gossip."  Silver's site now resides at www.rPulse.com [6].
