Weekly Patent Digest

Activision Blizzard's 1 patent addresses a problem familiar to anyone who has played a visually demanding game on modest hardware: shadow rendering costs. The patented system dynamically budgets shadow map resolution on a per-light basis within a single frame, then applies filtering to soften the results, keeping performance stable across a range of platform capabilities.

EA's 1 patent takes aim at cloth simulation, one of the more computationally expensive parts of rendering a character in motion. Rather than calculating physics at runtime, the patented approach uses a trained neural network that takes joint rotation data as input and predicts the clothing mesh and normal maps directly, reducing the real-time cost of making a character's outfit move convincingly.

Apple's 1 patent describes a rendering pipeline built for wireless VR and mixed reality headsets, splitting the workload between the headset itself and a separate base station. The system draws on a combination of foveated rendering, warp space rendering, slice-based rendering, and dynamic rendering adjustments to maintain high frame rates and low latency without requiring a physical tether between the two devices.

Cygames filed 1 patent covering a method for training game AI using recorded player replays. The approach weights historical player data, converts game states and actions into text representations, and generates order variants from that data to help the model predict what action should come next from a given game state.

NetEase's 1 patent connects the marketplace experience directly to gameplay. When a buyer considers purchasing a tradeable virtual character or item, the system spins up a cloud game session with that specific item already active, letting the buyer play with it before completing the transaction.

AviaGames secured 1 patent for a system that automatically scores the degree to which a game's outcomes are determined by skill versus chance. That classification then feeds into platform-level decisions around rules, resource provisioning, and anti-cheat measures.

GN Store Nord's 1 patent covers a highlight capture method built around a rolling buffer held in fast storage. The buffer continuously holds a window of recent gameplay, and when the player triggers a defined action, that window gets written to permanent storage, preserving the moment without requiring the entire session to be recorded continuously.

Tencent's 1 patent describes a HUD element that functions similarly to a compass, displaying guidance information about nearby game assets. The display style adjusts as the player moves through the game world, with the design aimed at improving spatial awareness during exploration while also reducing GPU load.

Razer's 1 patent covers a controller trigger mechanism that supports 2 distinct modes of operation within a single piece of hardware. A selector-driven interception member lets the trigger either actuate a switch through a short pull or travel through its full analog range, depending on which mode the player has selected.
