11月18日，Valve与暴雪中国对外联合发布声明，指出将继续推动在北京市海淀区人民法院所发起，针对《刀塔传奇》开发商莉莉丝与中清龙图的著作权、商标权及不正当竞争诉讼。
V社从今年4月发起该诉讼并由法院立案，暴雪中国于6月9日经法院通知作为该诉讼第三人加入。依据司法程序，该诉讼目前正在审理中。
声明稿中指出，该诉讼旨在寻求法院判决中清龙图停止营运由莉莉丝游戏开发并由其发行营运的手机游戏《刀塔传奇》，以及赔偿由于该款游戏侵犯Valve旗下游戏《Dota 2》与暴雪的《魔兽》系列游戏著作权、商标权及不正当竞争造成的损失。
依据Valve与Blizzard基于其在先权利以及上述诉讼请求提出的下架要求，中国苹果App Store近日已将《刀塔传奇》从其应用商店中下架，游戏内充值通道也已经关闭。
对于之前龙图借部分媒体之口表示的下架是因为苹果商店的技术性问题。本次联合声明指出下架完全是因为V社和暴雪中国在苹果商店提出的下架申请，并不涉及任何技术问题。
Valve与暴雪表示日后将继续推动旗下创意游戏作品的保护工作，并指出两间公司相信中国的法律体系不仅能维护其合法权益，也会为中国整个游戏产业营造一个健康的市场环境。Valve与暴雪期待与各自的中国合作伙伴共同携手，共同推动中国游戏产业的良性发展，从而惠及整个产业以及所有中国玩家。
以下是公告英文原告：
BLIZZARD AND VALVE CONTINUE TO PURSUE LEGAL CLAIMS AGAINST LILITH GAMES AND LONGTU
November 18th， 2015 -- Valve Corporation and Blizzard Entertainment continue to pursue claims for ongoing copyright and trademark infringement and unfair competition against Lilith Games and Longtu Games in Beijing Court of Haidian District。 The original lawsuit was brought by Valve in April of this year and Blizzard joined as a third party claimant on June 9， 2015。 The litigation is currently progressing according to Chinese court practice。
The complaint seeks an injunction and damages related to Dota Legend， a mobile game developed by Lilith and distributed by Longtu， for copyright and trademark infringement of and unfair competition against Valve‘s Dota 2 and Blizzard’s Warcraft games。
Apple recently removed the Dota Legend game from its App Store。 The removal was the result of a request by Valve and Blizzard to take down the game based on their prior rights and the legal claims the companies are pursuing。 Contrary to recent reports， the takedown of Dota Legend did not relate to technical issues， but in fact followed Valve and Blizzard‘s request for the game’s removal。
Valve and Blizzard will continue to press ahead with their claims in order to protect their creative works。 The two companies are confident that the Chinese legal system will protect their rights and lay out a path that will ensure a healthy environment for the gaming industry in China at large going forward。 Valve and Blizzard look forward to working with their Chinese partners in this collaborative effort to advance the positive growth and development of the Chinese gaming industry to the benefit of the industry and all Chinese players。
