A Texas federal court is now the battleground in the Apple Liquid Glass Design lawsuit, where Peer Global Inc. alleges that Apple’s sleek new “Liquid Glass” interface infringes three of its patents tied to a core user interaction technology known as the “selection ring.”

Peer Global, a company behind what it describes as an artificial intelligence operating system, claims Apple’s design borrows from a foundational system it developed to move beyond traditional cursor-based navigation.

“Apple continues to infringe one or more claims of the patents-in-suit within the United States, and plans to continue to do so in the future,” Peer alleged in its complaint.

The Technology at the Heart of the Dispute

At the center of the lawsuit is Peer's “selection ring,” which it characterizes as a natural, spatial pointer aligned with how users intuitively engage with screens. Instead of tapping through rigid menus or navigating flat lists, Peer says its system offers a “shared digital scape” rooted in real-world geography.

According to the complaint, Peer designed its platform as a continuous, shared digital environment mapped to real life — a persistent world where users can interact with AI models together, carrying shared context across time and place.

“Peer designed its technology as an operating environment where users can interact with artificial intelligence models together inside a persistent world, with shared context that carries across time, place, and activity,” the lawsuit states. The system enables users to move through real-time experiences, discover trending hubs and track social hotspots worldwide.

The patents at issue describe a movable selection ring that appears as an overlay, selecting items based on its relative position to on-screen elements. The approach, Peer says, reduces reliance on conventional cursor controls or precision tapping by allowing input through spatial positioning.

Apple’s Liquid Glass Under Scrutiny

Apple has described Liquid Glass as a translucent material that reflects and refracts surrounding content, dynamically shifting to bring greater focus to apps, controls and navigation.

“The new material, Liquid Glass, is translucent and behaves like glass in the real world,” Apple said in a June announcement. The company said the design adapts intelligently between light and dark modes, with color influenced by surrounding content.

Liquid Glass spans across iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26 and tvOS 26, forming a unified aesthetic across Apple’s ecosystem.

Peer contends that Apple’s system allows users to control the presentation of information within a graphical user interface in a manner similar to its patented selection ring. The complaint alleges that Apple devices receive user manipulation of a selection ring’s position without altering the location of icons displayed on the screen — a feature Peer says mirrors its own patented methods.

The lawsuit further claims Apple Store employees use techniques described in Peer's patents when demonstrating devices to customers.
