The NameTag Complaint Cites a Meta Patent Whose Title Argues the Other Way

The filing runs to 66 pages. Alvarez v. Meta Platforms, Inc. was docketed on September 4 in the United States District Court for the Northern District of Illinois as case number 1:26-cv-10773, and assigned to Judge April M. Perry. Four plaintiffs are named. Francisco Alvarez and his minor son are Illinois residents. Jeremy Wahl and his ten year old daughter are Californians. The counts run under sections 15(a) and 15(b) of the Illinois Biometric Information Privacy Act, the California common law right of publicity, California Civil Code section 3344(a), and the privacy provision of the California Constitution.

The theory is that Meta took faces out of Facebook and Instagram, converted them into biometric identifiers, and used those identifiers to train both its image generation models and the face recognition system it had been preparing for its AI glasses. The proposed class period opens on September 4, 2021.

The exhibit that came out of the patent office

Paragraphs 99 through 105 of the complaint reach past the reporting and into Meta's own patent filings.

United States patent publication 20260142974 A1 is titled "User identity verification without sharing biometric data with platforms." Meta Platforms is the applicant. The named inventor is Shing Sheung Daniel Ip. It was filed on October 9, 2025 and published on May 21, 2026, roughly a month before Meta Glasses went on sale. The document describes a device capturing an image or video of a face and generating a biometric face embedding from it. That embedding is then compared against embeddings derived from profile photographs and tagged photographs the platform already holds. Smart glasses are among the device types it lists.

The plaintiffs call this a blueprint. Paragraph 104 argues the application "does not describe a hypothetical or generic computer-vision concept" but a complete operational workflow. Paragraph 105 concludes that Meta "had designed and implemented the core technical components necessary to identify real-world individuals from images captured by Meta smart glasses."

Then the complaint concedes the weakness in its own exhibit, which is not a common move. Paragraph 103 acknowledges that the patent "emphasizes a privacy-preserving architecture in which certain biometric embeddings need not be transmitted from the user's device to Meta's servers." The title says as much in its last six words. A patent describing how to verify somebody without handing biometric data to a platform is an awkward thing to cite as evidence that a platform is hoarding biometric data, and the plaintiffs clearly know it. Their answer is that the filing proves capability rather than practice. The pipeline exists; what Meta chose to do with the output is a separate question. That is a serviceable argument, and it is a narrower one than the case looks like from the headlines.

Where NameTag came from

NameTag is the dormant face recognition code that WIRED reported finding in the Meta AI companion app in June. The complaint quotes that reporting at paragraph 22. The feature would turn faces captured by the glasses into "unique biometric signatures, commonly known as faceprints, and check each one against faceprints stored on the user's phone." That phone-side database, WIRED found, was configured to receive updates from Meta.

The complaint describes NameTag as code that reached phones without ever being switched on, and alleges at paragraph 45 that Meta has since removed it from the app. Removal settles nothing, the plaintiffs say, because the identifiers the feature would have matched against were created and stored long before any of it shipped.

The clause that already moved the problem onto the wearer

The most durable thing in this story is not in the complaint. It sits in Meta's Supplemental Meta Platforms Technologies Terms of Service, section 2.1, last updated April 29, 2025, and the complaint flags it at paragraph 85. It reads: "You are also responsible for complying with all applicable laws when using MPT Products, including providing any notice to or obtaining any consents from other individuals who you interact with on your MPT Products as may be required under video recording, audio recording, biometric data, or other privacy or data protection laws."

That sentence hands the consent obligation to the person wearing the glasses, for every person in front of them. Whether a contract term can do that against a statute like BIPA, which attaches its duties to whoever collects the identifier, is a question for a judge rather than a product page. It is also the question that outlives NameTag.

An April letter and a 2021 promise

On April 13 the ACLU of Massachusetts posted an open letter to Mark Zuckerberg signed by, in its own words, "the undersigned 77 local, state, and national organizations." The complaint puts the number at 75. The letter as posted says 77. Its central line: "The American people have not consented to this dystopian privacy invasion, and indeed there is no way to obtain meaningful consent of all people impacted." The complaint alleges that Meta neither answered the letter nor disavowed the feature.

Five years earlier, Andrew Bosworth had made the case for consultation himself. Paragraph 77 of the complaint quotes an interview from February 2021 in which Meta's chief technology officer called face recognition in glasses "really a debate we need to have with the public," adding that "if people don't want this technology, we don't have to supply it." Paragraph 78 of the filing answers him in one sentence. The debate never happened.

What a buyer takes from this

Nothing on sale this morning works differently than it did last week. What changed is that a set of numbers now has a courtroom attached. The prayer for relief asks $5,000 for each intentional or reckless BIPA violation and $1,000 for each negligent one. The jurisdictional pleading puts more than $5 million in controversy under the Class Action Fairness Act. The plaintiffs estimate the national class in the millions, working from their own count of more than 250 million Facebook and more than 160 million Instagram users in the United States.

Institutions have been ahead of the consumer conversation here for months. ICE classified the glasses as body-worn cameras in August and barred them for every employee. Meta has spent the year hardening the capture indicator, first by bricking the camera when the LED is tampered with and then by checking it for the whole recording rather than once at the start. Those are engineering answers to a social problem and they are worth something. Neither touches section 2.1. Anyone deciding this quarter whether to put a pair on an employee's face in Illinois or California is now doing that arithmetic with per-violation statutory damages on the other side of the ledger, and with an open question about who the statute says is doing the collecting. That is not the calculation that was available in April, when the earlier Ray-Ban Meta privacy suit turned on what happened to footage after it was captured rather than on the faces themselves.
