This week's digest covers 6 granted patents from 5 companies, with cloud gaming and graphics each representing 2 patents, followed by UI/UX and hardware with 1 each.
The patents span control and security infrastructure for cloud gaming platforms, including South Park Digital Studios' remote intervention system and NVIDIA's hierarchical encryption for secure game distribution. Graphics advancements focus on rendering techniques, from Nintendo's event-driven lighting transformations to Miris' volumetric video encoding for immersive media. Nintendo also patents a layered map system that tracks player movement across multiple vertical zones, while Guangzhou Chicken Run addresses mobile gamepad compatibility through adjustable hardware design.
South Park Digital Studios patented a live game intervention system that allows a second device to remotely control aspects of another player's active cloud gaming session in real time. The system operates while the primary player's game remains running, enabling external manipulation of gameplay elements without interrupting the session.
Nintendo filed 2 patents this week, covering both graphics rendering and user interface design. The first patent describes a dynamic visibility system that transforms dark virtual spaces into illuminated areas based on in-game events, changing how players experience exploration in shadowy environments. The second patent covers a multi-layer map tracking system that displays player movement history across ground, air, and underground zones, with distinct visual differentiation applied to each vertical layer.
NVIDIA patented a hierarchical encryption system for cloud gaming that embeds encrypted keys directly in game build filenames. The approach enables secure distribution of game builds without exposing the actual files to end users, addressing security concerns in cloud-based game delivery infrastructure.
Miris patented smooth 3D Gaussian splatting encoding for dynamic spatial data streams, designed to eliminate visual popping artifacts during real-time volumetric video playback. The system targets VR, AR, and other immersive media applications that require continuous rendering of three-dimensional video content.
Guangzhou Chicken Run Network Technology Co. patented an adaptive gamepad that uses a spring-loaded USB interface assembly to automatically accommodate mobile phones of varying sizes. The mechanical design addresses universal compatibility challenges by adjusting to different device dimensions without requiring manual configuration.
