This month's AI & Machine Learning category includes 12 granted patents from 5 companies: Sony (8), Dell (1), EA (1), GDM Holding (1), and Microsoft (1).
Sony's patents span systems that convert player selfies into game-appropriate avatars, translate sign language into chat messages, customize NPC dialogue based on interaction history, and capture biometrics to adapt gameplay difficulty. EA and Microsoft described generative AI approaches, with EA focusing on automated facial animation from speech audio and Microsoft covering narrative content creation from natural language prompts. The category also includes multi-agent reinforcement learning for AI training and predictive analytics for marketing content optimization.
EA received 1 patent for a system that generates facial animations directly from speech audio by detecting the emotional tone in a character's voice. The technology analyzes both the phonetic content and the emotional delivery of dialogue, then automatically produces matching facial expressions frame by frame. This eliminates the need for animators to manually craft expressions for every line of game dialogue.
Sony received 8 patents covering character creation, communication systems, and adaptive gameplay mechanics. Multiple patents address avatar generation, with one transforming user selfies into characters that match a game's visual style and another combining video-based motion capture with text descriptions to create personalized avatars with custom animations. The company also described communication tools that rewrite in-game messages to match each recipient's current gameplay context and translate sign language gestures into chat text that adapts based on what's happening in the game. Another patent analyzes how individual players interact with NPCs over time, then customizes future dialogue based on those patterns. Sony also patented technology that captures biometric data like heart rate during gameplay, using it to create highlight reels for spectators, bookmark emotionally intense moments, and adjust NPC behavior when players show signs of stress. Additional patents cover voice recognition that identifies multiple players speaking simultaneously for hands-free control and predictive analytics that estimate how well game trailers will perform with audiences before they're released.
GDM Holding received 1 patent for a reinforcement learning framework that trains AI agents by strategically pairing them during practice sessions. The system allows agents to learn cooperatively and competitively from each other using different strategies and training parameters, creating a group of AI models that improve collectively rather than in isolation.
Microsoft received 1 patent describing a generative AI system that creates narrative game content from natural language instructions during development and continues generating content during gameplay based on how players respond. The approach positions AI as a design assistant that translates developer prompts into game elements while also adapting the experience in real time by monitoring player engagement signals.
Dell received 1 patent for a game controller with a movable internal weight that shifts the device's center of gravity in response to in-game events. This provides directional physical feedback beyond traditional vibration, allowing developers to communicate movement, collisions, and other gameplay moments through changes in how the controller balances in a player's hands.
