3D Acoustic Signature & Directional Haptic Trade Dress

Statutory Hook: 15 U.S.C. § 1125(a) (Non-Functional Trade Dress)

Lanham Act trademark protection for proprietary spatial audio chimes, gaze-selection acoustic cues, and virtual interface haptic pulse frequencies.

Doctrinal Framework & Legal Mechanics

Sensory marks under the Lanham Act protect non-visual commercial source identifiers, including NBC's chimes and MGM's lion roar. In spatial computing headsets, proprietary binaural acoustic chimes and directional haptic pulses signal operating system confirmation. Registration requires proving distinctiveness and overcoming the functionality doctrine.
