Firm files patent lawsuit against Activision Blizzard, Zynga

Walker Digital accuses World of Warcraft, Call of Duty and Mafia Wars of infringing its patent

An invention firm started by Priceline.com founder Jay Walker has filed a lawsuit against two large computer gaming companies, Activision Blizzard and Zynga, alleging that some of their most popular games infringe on an online tournament patent.

Walker Digital, in a complaint filed Monday in U.S. District Court for the District of Delaware, alleged that a number of games offered by the two companies infringe a July 2002 patent related to online tournaments. Patent No. 6,425,828 is for a database-driven online distributed tournament system.

The Activision Blizzard games that infringe the patent, according to the complaint, including World of Warcraft and three add-on games, Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, and DJ Hero 2.

The Zynga games named in the complaint include Mafia Wars, Fashion Wars and Special Forces.

Walker Digital is seeking monetary damages in the lawsuit. The amount of damages wasn't named in the nine-page complaint.

Representatives of Activision Blizzard and Zynga didn't immediately respond to requests for comment on the lawsuit. Walker Digital also did not respond to a request for comments.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
