The battlegrounds inside the on-device AI privacy push

the fights inside the fight · each with its three newest filings · new filings join every week

Training AI Without Touching Your Data 42 filings

Qualcomm 11, Google 10, Sony 8

Several companies are filing patents for ways to teach AI using real-world data while making sure that data never leaves your device.

Keeping Ad Targeting Private 26 filings

Google 25, Microsoft 1

A large group of filings covers serving targeted ads without storing who you are or what you browse, doing the matching on your device instead of on a server. They range from picking winning ads to counting trends without ever seeing individual people.

Hiding Identity From Apps and Services 29 filings

Google 8, Apple 7, Qualcomm 6

Multiple companies are working on ways to stop apps and services from learning who you really are, using stand-ins, decoys, or encrypted replacements instead of your real details.

Running AI Fully On Your Device 27 filings

Google 10, Samsung 5, Microsoft 3

Companies are filing patents for AI that does its work entirely on your phone or computer without sending anything to a server, covering tasks like grammar checking, recommendations, and answering questions.

Stopping Private Data From Leaking Out 36 filings

Microsoft 9, Google 7, IBM 6

A cluster of patents focuses on catching and blocking sensitive data before it escapes, whether during software testing, code sharing, login flows, or blockchain transactions.

US 2026/0246917 A1

Samsung Patents a Display That Hides Personal Info in 3D Depth

A display that geometrically distorts sensitive content based on viewing angle keeps passwords and financial data unreadable from side glances, shifting the privacy perimeter from software detection to the physical properties of the screen itself.

US 2026/0238561 A1

Apple Files Patent for a System That Manages AI Models Across Devices

Coordinating model versions across devices requires tracking which training data belongs to which model update. Apple's patent covers the infrastructure needed to keep distributed models synchronized without mixing datasets across phones, tablets, and servers.

US 2026/0228631 A1

New Patent Trains AI Locally Without Sharing Your Data

Local model training followed by encrypted weight-sharing lets devices improve a central AI without exposing raw user data to servers, shifting the privacy burden from input filtering to parameter transmission.

US 2026/0164075 A1

New Patent Keeps Ad Targeting Data On Your Device

Devices holding ad-profiling data locally means ad networks stop building remote dossiers on individual users. Google's approach shifts the tracking infrastructure from centralized servers to local processing, eliminating the data collection step entirely.

US 2026/0161677 A1

Patent: AI Decides When to Pull Your Personal Data Before Answering

Knowing when personal data actually improves an answer cuts unnecessary data exposure. Google's patent describes AI that retrieves your information only for questions where context genuinely matters, reducing privacy risk from indiscriminate profiling.

Questions readers ask

What problem is this watchlist actually about?

These filings show Big Tech engineers working on ways to run AI tasks like recommendations, voice assistants, and ad targeting directly on a phone or TV instead of a server, so personal data never has to leave the device. The goal is doing useful AI work while keeping raw user data local.

Does this mean Google and Samsung phones already run AI without sending data anywhere?

Not yet, and patents are not proof of a shipped feature. What we see is a documented direction: both companies are filing designs for scrubbing, filtering, and training AI locally, which signals engineering priority even before any feature reaches a real device or app.

Why does Samsung's post-quantum patent show up in a privacy watchlist?

It fits because the watchlist tracks device-level trust, not just data scrubbing. A post-quantum authentication system is about making sure a device can prove its own identity securely even after future computers break today's encryption, which supports the same on-device privacy goal from a different angle.

Who is filing the most patents in this race?

Right now the sample leans heavily toward Google, with Samsung also contributing filings on data substitution and future-proof security. The watchlist is designed to track new filers as they appear, so the balance between companies can shift as more patents get added each week.
