Walk the independent claim. Magic Leap's grant US12298517B2, "Augmented reality display with waveguide configured to capture images of eye and/or environment" (issued May 13, 2025; a multi-inventor filing), is a granted patent. Its CPC mix — G02B 27/0172 optics, G06F 3/013 gaze input, G06T 19/006 rendering — spans optics and sensing in one claim.
The element that does the work is bidirectionality. A conventional AR waveguide is a one-way street: it carries the display image to the eye. This claim makes the same waveguide a two-way path — also capturing images of the eye for gaze tracking and of the environment for scene understanding. Folding sensing into the display optic is the defensible advance.
What it reads on is a next-generation AR headset that integrates eye tracking and environment capture into the display waveguide rather than using separate cameras — a path to thinner, simpler optics. Magic Leap's whole identity is waveguide optics, and this grant extends that lead into the sensing function.
Scope discipline: the claim protects the recited image-capturing waveguide, not AR optics generally and not eye tracking done with discrete cameras. A headset that tracks gaze with a separate camera, or senses the environment with dedicated sensors, operates outside it. The defensible element is the waveguide doing double duty as display and camera.
Granted status makes US12298517B2 a live obstacle in advanced AR optics, where consolidating components into the waveguide is a clear industry direction — fewer separate cameras means thinner, lighter glasses. Anyone pursuing that consolidation should map their design against this bidirectional-waveguide claim.
For a strategist, the patent shows the AR-optics frontier moving from "get the image out" to "get the image out and pull sensing data back in through the same element." Magic Leap claiming that frontier in 2025 is consistent with its decade-long concentration in the light path — now extended to make the light path sense as well as display.
