BASF subsidiary TrinamiX filed a patent infringement lawsuit against Apple on September 3, alleging that Face ID in newer iPhones and iPad Pro models infringes seven patents covering skin detection technology during facial authentication.
As first reported by Reuters, TrinamiX claims Apple’s implementation of liveness detection and skin verification in Face ID directly violates its intellectual property. The complaint targets the entire iPhone 15, iPhone 16, and iPhone 17 lineups, plus iPad Pro models with Face ID. TrinamiX is requesting a jury trial in the U.S. District Court for the Western District of Texas.
What TrinamiX’s Patents Actually Cover
The seven patents center on technology that detects human skin during facial authentication, specifically to prevent spoofing attacks using detailed 3D masks. Security researchers have historically defeated earlier Face ID versions by constructing specialized masks that fooled the original sensor array. TrinamiX’s patents address this vulnerability through liveness verification and skin-presence detection, marking a security layer Apple has integrated into newer Face ID implementations.
Hardware Named in the Lawsuit
The lawsuit targets the following devices:
- iPhone 15 series: iPhone 15 iPhone 15 Plus, iPhone 15 Pro, iPhone 15 Pro Max
- iPhone 16 series: iPhone 16, iPhone 16e, iPhone 16 Plus, iPhone 16 Pro, iPhone 16 Pro Max
- iPhone 17 series: iPhone 17, iPhone 17e, iPhone 17 Pro, iPhone 17 Pro Max
- iPad Pro models: Recent iPad Pro variants with Face ID
Who TrinamiX Is and What It Wants
TrinamiX describes itself as a BASF spin-off that designs, develops, and commercializes advanced sensing technologies including biometric imaging, three-dimensional vision, and near-infrared spectroscopy solutions for consumer and industrial applications. In its complaint, TrinamiX seeks a court finding of patent infringement, an injunction blocking Apple from manufacturing or selling the accused products, and damages plus attorneys’ fees.
Why the Western District of Texas Matters
The choice of venue signals strategic confidence. The Western District of Texas has developed a reputation as a plaintiff-friendly jurisdiction for patent litigation, historically producing verdicts and settlements favorable to IP holders. This venue selection suggests TrinamiX believes it has a strong case and expects a receptive hearing compared to courts like the Northern District of California, where Apple has more leverage.
The lawsuit arrives as Apple faces mounting biometric patent exposure. The company settled a $634 million judgment with Masimo in 2025 over health sensor patents and has faced claims from Identity Security LLC and others in recent years. Face ID’s technical complexity and reliance on proprietary sensor architecture make it a persistent target for patent challengers holding foundational IP in facial recognition, infrared sensing, and liveness detection.
