BASF’s Face ID Lawsuit Against Apple: The Claims, Products and Stakes

BASF subsidiaries trinamiX Sensing LLC and trinamiX GmbH filed a patent-infringement complaint against Apple on September 3, 2026, in the Midland Division of the U.S. District Court for the Western District of Texas. The case, trinamiX Sensing LLC et al. v. Apple, Inc., is docketed as No. 7:26-cv-00348.2728

The central allegation is that Face ID in newer Apple devices uses patented technology for distinguishing human skin from artificial materials during facial authentication. Apple had not immediately commented publicly, and the complaint is an allegation—not a court finding of infringement.1

What BASF says Apple infringed

trinamiX alleges that Apple infringes seven U.S. patents covering optical material-identification and skin-detection techniques. In practical terms, the claimed technology is intended to make facial authentication harder to fool by assessing whether a presented face is genuine human skin rather than a photograph, 3D-printed mask or silicone replica.19

This type of protection is commonly described as liveness or anti-spoofing detection. The suit does not establish that Apple’s Face ID lacks security or that Apple copied any technology; it contends that Apple’s later implementation uses trinamiX’s patented methods without authorization.127

Which Apple products are named

The complaint reaches multiple iPhone and iPad generations. Public reports identify the iPhone 15, iPhone 16 and iPhone 17 series, along with recent iPad Pro models, among the accused products; the allegations also extend to other Face ID-equipped iPhones and iPads.127

That device scope matters because the case concerns a feature used across major Apple product lines. Apple reported $196.5 billion in iPhone sales and $21.7 billion in iPad sales for the nine months ended June 27, 2026. Those revenue figures are useful context for the scale of the affected categories, but they are not an estimate of damages in this lawsuit.1

The alleged Face ID timeline

trinamiX’s claim is specifically about later changes to Face ID. Apple introduced Face ID with the iPhone X in 2017, and the complaint reportedly acknowledges that the original launch did not use the disputed trinamiX technology.114

Instead, trinamiX alleges that Apple subsequently updated Face ID in newer products to incorporate material- and skin-detection capabilities covered by the seven asserted patents. The reports provided do not identify a specific date when that alleged use began or describe Apple’s implementation in greater technical detail.19

What trinamiX alleges about Apple’s knowledge and harm

The plaintiffs contend that Apple “knew or should have known” there was a high probability that updating iPhones and iPads to use Face ID with material and skin detection would infringe the asserted patents. They also allege substantial monetary damage and irreparable injury.312

These statements are claims from the complaint. Whether Apple had the alleged knowledge, whether the patents are valid, and whether Apple’s systems fall within the patents’ scope will be questions for the litigation.

What BASF is asking the court to do

trinamiX is seeking monetary damages in an unspecified amount and an injunction that would bar further infringement. No public report in the supplied materials identifies a specific dollar amount requested.67

An injunction request does not mean Face ID will be disabled or that Apple will necessarily be required to alter products. Such relief would depend on later legal rulings, and the case was at the complaint stage in the reported coverage.16

Where trinamiX came from

The technology at issue traces back to BASF research into organic solar cells. BASF and trinamiX say researchers observed an unexpected effect in that work, which helped lead to 3D-sensing technology.3132

There is a date discrepancy in the available accounts. Reporting on the lawsuit describes BASF creating trinamiX as a standalone entity in 2014, while BASF’s and trinamiX’s current corporate materials say trinamiX GmbH was spun off and founded as a wholly owned BASF subsidiary in 2015.293135

BASF says trinamiX develops biometric-imaging and mobile near-infrared spectroscopy solutions and holds more than 800 patents and patent applications worldwide. That portfolio figure should not be confused with the litigation: the Apple complaint asserts seven patents.3527

The bottom line

BASF’s lawsuit is a challenge to Face ID’s alleged later use of anti-spoofing material and skin detection—not to Face ID as it existed when Apple launched the iPhone X in 2017. The case may be commercially significant because it reaches recent iPhones and iPads, but no infringement has been established and no damages amount has been disclosed.114
