Week of November 12, 2026 · 8 filings covered · refreshes every week
The 8 filings Patentlyze covered this week split across three themes: controlling what AI and software can access, protecting data during audits and testing, and hardening physical and environmental sensing.
In a city of glass and concrete, one gunshot reaches your ears as a dozen sounds, because every building bounces it back. Microsoft's patent application describes a way to work out which sound is the original.
Phones are filling up with AI helpers that can open your photos, your banking app and the internet, and many will come from third parties. Samsung's patent application describes a supervisor AI whose only job is to keep the others in line.
Samsung's filing describes reading a damaged fingerprint the way you follow a broken dotted line: keep heading the same direction until the line picks back up. It even treats the gaps as a clue for spotting scars.
Privacy and oversight usually pull in opposite directions. IBM's patent application tries to hand an auditor one person's payment history for one time window, and nothing else.

Chips only have so many burn-once switches, so Nvidia's patent application turns a simple count of how many have been flipped into a record of who owns the chip.
Software has to be tested on realistic data before it reaches you, but the most realistic data is often the data privacy laws forbid developers from using. IBM's patent application describes a way to keep the useful parts of real customer records and scrub out the parts that point to a person.
Privacy and oversight usually pull in opposite directions. IBM's patent application tries to hand an auditor one person's payment history for one time window, and nothing else.
Ask a security tool to "find processes that changed the hosts file often" and it has to guess what "often" means. IBM's filing describes a way to make it look things up, ask questions and check itself before it writes the rule.
In a city of glass and concrete, one gunshot reaches your ears as a dozen sounds, because every building bounces it back. Microsoft's patent application describes a way to work out which sound is the original.
Microsoft's filing proposes a fresh encryption key for every small chunk of server memory, built in about five clock cycles instead of the usual 20 to 30.
Samsung's filing describes reading a damaged fingerprint the way you follow a broken dotted line: keep heading the same direction until the line picks back up. It even treats the gaps as a clue for spotting scars.
Every time a developer saves a change to an app, this OpenAI patent application has an AI write a custom security checklist, review the change against it, and then try to run the bug to prove it's real.
When one AI agent asks another to do a job, Salesforce's new patent application says the receiver should check the sender's identity and the whole trail of hand-offs behind the request.
AI models cost a fortune to build, and the moment one lands on your laptop, it becomes easy to steal. Microsoft's patent application describes a locked room inside the chip where only approved parts can read the model.
Your work login proves you are you. Microsoft has filed a patent application for a version that does the same for robots and AI agents, so a human team can bring them into a shared mission and control what each one is allowed to do.
Over the last 90 days, Microsoft leads with 51 security filings, followed by Google (21), IBM (21), Apple (15) and Samsung (12). That is out of 143 security filings from all the companies we track in the same period.
27 security patent applications from the companies we track have published in November 2026 so far, after 60 in October. Patentlyze has covered 341 security filings since May 2026.
Samsung Patents a System That Keeps AI Programs From Misusing Your Phone's Data, a Samsung filing published November 12, 2026. The latest filings are listed above, newest first.
No. A published application is not a product announcement. Companies file to protect options, and most patented ideas never ship in the form described. What filings do show is which companies are putting research effort into security right now.
