Sifang Lu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9937414
    Abstract: Software on a server transmits a copy of a string of text data containing game state parameters to a client device executing an instance of a computer-implemented game. The string is serialized and unstructured. The instance modifies the game state parameters according to game logic and events generated by a user as the user plays the game. The software on the server then receives a batch file transmitted after a threshold period of time by the instance. The batch file includes a plurality of events. The software processes the plurality of events in the batch file against game logic to update one or more of game state parameters in the string and stores the text data in the updated string in a persistent database.
    Type: Grant

  • Patent number: 8745015
    Abstract: Software on a server accesses a batch file including a plurality of events generated by a remote game client application executing an instance of the computer-implemented game. The software accesses a game state data object associated with the instance of the computer-implemented game. The game state data object includes one or more game state parameters formatted as a serialized unstructured string of text data. The software parses the game state data object to identify the one or more game state parameters. The software processes the plurality of events in the batch file against game logic to update one or more of the game state parameters in the game state data object. The game logic incorporates information extracted from a social graph. And the software stores the game state data object in a memory cache.

  • Patent number: 8290920
    Abstract: In one embodiment, accessing, using a computing device, a batch file comprising a plurality of events generated by a remote game client application executing an instance of a computer-implemented game; accessing, in response to the batch file, a game state data object associated with the instance of the computer-implemented game, wherein the game state data object includes one or more game state parameters formatted as serialized unstructured data; parsing the game state data object to identify the one or more game state parameters; processing the plurality of events in the batch file against game logic to update one or more of the game state parameters; re-serializing the one or more game state parameters into an updated game state data object; and storing the game state data object in a memory cache.
