Brian Kopp, author of The
Ultimate World of Warcraft Leveling & Gold Guide, along with public-interest advocacy group Public Citizen, have filed a lawsuit
against Blizzard after the company successfully barred the sale of Kopp's unauthorized guide on eBay. Kopp and Public
Citizen contend that the guide does not violate copyright and trademark laws, and that Blizzard, Vivendi, and the ESA
violated Kopp's First Amendment rights by repeatedly issuing complaints to eBay about the book's sale, eventually
prompting its removal from the online auction site and the suspension of Kopp's eBay account.The lawsuit seeks monetary compensation to cover lost profits, an injunction preventing Blizzard, Vivendi, and the ESA from interfering with future sales, and a judgment that the guide is protected by the First Amendment and doesn't interfere with intellectual-property rights. Currently, Kopp is selling the guide (using PayPal) on a personal website.
