Worlds, Inc. v. Activision Blizzard, Inc. et al

Case Summary: 12-cv-10576 

This is an action pending in the District Court of Massachusetts for patent infringement arising under federal patent laws. On March 30, 2012, Plaintiff Worlds, Inc. filed a complaint against Defendant Activision Blizzard, Inc. and its subsidiaries alleging five separate counts of patent infringement. Plaintiff holds patents on technology used in online multiplayer games to create virtual online environments in which large numbers of users can interact. Defendants publish online, personal, computer, console, handheld, and mobile games worldwide.

Plaintiff alleges infringement of five of its patents stemming from Defendants’ manufacture, use, and sale of two popular online, multiplayer game franchises, World of Warcraft and Call of Duty. Plaintiffs have asked the court to award damages and order Defendants to cease the alleged infringement. On June 18, 2013, Defendants filed a motion for summary judgment, asking the court to decide as a matter of law that the five patents at issue are invalid based on Plaintiff’s public use of the technologies prior to the patents’ filing dates. Plaintiff opposes the motion, arguing that the effective filing date is earlier than shown on the patents at issue due to clerical error. This video shows the hearing on Defendants’ motion for summary judgment.
