FIG. 5 shows avatars (gamvatars) having a game item function according to an embodiment of the present invention, and it exemplifies gamvatars 530 and 540 generated by combining an avatar 510 which wears clothes purchased at the avatar shop 430 and a game item 520 purchased at the item shop 440. The gamvatar 530 shows the avatar 510 but is arranged in the background layer. As described above, it is possible for the avatar 510 to wear the item 520 or not wear the item 520 depending on the user's setting. ('743 patent, col. 6, lines 33-44).

On Feb. 8, 2018, Pure Data Systems, LLC (“Pure”) sued Electronic Arts, Inc. (“EA”) and Ubisoft, Inc. (“Ubisoft”) for alleged infringement of U.S. Patent Nos. 5,999,947 to Zollinger et al. and 6,321,236 to Zollinger et al.  



Claim 1 of the ’947 Patent reads:

1. A method of distributing database differences corresponding to change events made to a database table located on a server computer to client copies of the database table located on one or more client computers comprising the steps of:
  creating and storing on the server computer one or more sequentially versioned updates, each update containing database differences in a generic format, the database differences corresponding to database change events made to the database table since the preceding update;
  receiving, from a client computer, a request for all the database differences needed to make the client copy of the database table current;
  determining which updates are necessary for making the client copy of the database table current;
  ascertaining a client database engine type wherein the client copy of the database table is held;
  generating and translating specific database differences, selected based on the necessary updates, into instructions based on the ascertained database engine type prior to transmission; and
  transmitting the specific database differences to the client computer so that the client computer may execute the instructions on the client database engine, thereby making the client copy of the database table current in response to the specific database differences translated into the instructions.

Pure claims that EA and Ubisoft infringe their patents via their “game library updates.”  For example, “if a user purchases a game through the [EA’s] Origin website using a browser, the user’s game library is updated on a server” such that “[w]hen the user next logs into the Origin client, those updates are transmitted to the Origin client running on the user’s computer.”

The lawsuits against EA and Ubisoft are different, likely due to venue issues, but the complaints are almost identical. Pure appears to have also filed similar complaints against Valve Corporation, the Fox News Network, Imgur, CNET, CNN, and Pinterest, among others.  

On November 6, 2017, Activision Blizzard, Inc. (“Blizzard”) filed a petition for inter partes review (“IPR”) against Game and Technology Co. Ltd. (“GAT”).  Blizzard is challenging claims 1-7 of U.S. Patent No. 7,682,243 (the “’243 Patent”).  The same claims in the same patent were challenged by Wargaming Group Ltd. (“Wargaming”) in IPR2017-01082, which Blizzard plans to join.



Activision’s IPR petition is responsive to a lawsuit that GAT brought against Blizzard in the Eastern District of Texas on July 9, 2015 (No. 2:15-CV-1257, now 2:16-CV-6499 in the C.D. Cal.).  In that case, GAT has asserted that Blizzard’s World of Warcraft infringes three patents: the ’243 Patent, U.S. Patent No. 8,253,743, and U.S. Patent No. 8,035,649.  In separate suits, GAT has sued Wargaming, Valve Corporation, and Riot Games, Inc.

The ’243 Patent generally relates to a “pilot” and a “unit associated with the pilot,” such as a player character and an animal mount.  Claim 1 of the ’243 Patent reads:

1. An online game providing method for providing a pilot and a unit associated with the pilot at an online game, the method comprising the steps of:

controlling an online game such that a player can manipulate a pilot and a unit associated with said pilot, said pilot being a game character operated by a player, said pilot representing the player, said unit being a virtual object controlled by the player;

maintaining a unit information database, the unit information database recording unit information on said unit, in which the unit information includes ability of said unit and sync point information;

maintaining a pilot information database, the pilot information database recording pilot information on said pilot, in which the pilot information includes a unit identifier indicating said unit associated with said pilot, ability of said pilot and the ability of said unit associated with said pilot;

receiving a request for update on first pilot ability information of a first pilot;

searching for unit identifier information associated with the first pilot by referring to the pilot information database;

searching for sync point information associated with the searched unit identifier information by referring to the unit information database; and

updating and recording the first pilot ability information and unit ability information associated therewith in accordance with the searched sync point information such that said ability of unit is changed proportionally to changes in ability of the pilot by referring to said sync point,

wherein said sync point information is a ratio of which changes in said ability of pilot are applied to said ability of unit, and said steps of searching for unit identifier information and of searching for sync point information are performed by a processor.

Blizzard argues that the ’243 Patent’s “alleged novelty” relates to the “sync point,” bolded above.  Per Blizzard’s petition, the ’243 Patent is anticipated because the Dungeons and Dragons Player’s Handbook Core Rulebook I v. 3.5 (“D&D 3.5”) discloses “player characters with animals whose abilities are synchronized based on ratio relationships, so that increases to the character’s abilities are applied proportionally to the animal’s abilities.”  For instance, D&D 3.5 allegedly discloses that a druid’s animal companion’s abilities increase corresponding to the class level of the druid.
