U.S. Patent No. 7,115,035: Method for controlling display of messages transmitted/received in network game
Issued Oct. 3, 2006, to Square Enix


The ’035 patent should appeal to anyone who enjoys playing online multiplayer games. This invention provides a way for multiple players to communicate during a game. The players are able to type text into the communication box and have it appear to the rest of his teammates. The text scrolls upward so that older messages make way for the newer ones. The older texts stay around for long enough that the player has a chance to read it first. The invention also calls for accomplishments to be acknowledged in the chat-text box. For example, if the player gets an ‘x’ number of kills (which is an accomplishment), the others players will be notified of this accomplishment via the text box. This invention was implemented in the game Quake 3 Arena.


Multiple video game apparatuses are connected to a game server apparatus. This network game progresses when players of the respective video game apparatuses exchange messages via the game server apparatus. When a predetermined event is generated by processing in the game server apparatus, a specific message is transmitted to each video game apparatus. In a chat window provided on a display screen of each video game apparatus, the message sent from the game server apparatus is scrolled and displayed from the bottom to the top. When the specific message reaches an uppermost portion of the chat window, a lock window is set and the specific message is displayed therein. The specific message in the lock window is not erased by the reception of a next message.
