A single search for homomorphic-encryption patents returns thousands of records. The assignee breakdown tells a clearer story than any one patent: this is now an enterprise IP race.

Post-quantum algorithms are not just new math; they are heavier to compute. A PQSecure patent on an area-efficient lattice architecture is where the algorithm meets the chip.
Cybersecurity
Most anomaly detection ships raw events to a central brain. A Forcepoint patent claims the opposite: let the endpoint maintain counters and flag its own deviations. The claim explains the tradeoff.
Cybersecurity
Confidential computing and encrypted analytics feel like 2020s ideas. The granted claim that made them mathematically possible is dated 2013 — and that timeline shapes who owns what.
Cybersecurity
Two phrases get blurred constantly. A 2025 Honeywell grant on distributing symmetric keys via QKD is a clean way to see what 'quantum' actually buys, and what it doesn't.
Cybersecurity
Zscaler, Sophos, and Capital One each got zero-trust grants within months of each other. Read side by side, they reveal a disagreement about where the policy decision should actually live.
Cybersecurity
The phrase is on every phone spec sheet and cloud security page. Two patents — a 2014 Intel grant and a 2024 VMware grant — bracket what the hardware actually does and where it's going.
Cybersecurity
Proving you know a secret without revealing it sounds like a paradox. An American Express patent family applies it to the most practical problem there is: paying without exposing your data.
Cybersecurity
A FireEye patent family — now carried forward to a 2024 Trellix grant — claims a detection method where endpoint and network sensors verify each other's verdicts. Here is what the claims cover.
Cybersecurity
The dream of computing on data you can't read is older than the hype. A 2013 Stanford grant on 'bootstrapping' is the claim that made it possible at all.
Cybersecurity
Most key-rotation schemes run on a clock. A January 2026 Dell grant claims rotating keys based on how much data a key has protected, which is the more defensible trigger.
Cybersecurity
A long-running patent family on post-quantum key exchange keeps coming back to the same idea: don't trust one new algorithm, run two key encapsulations at once.
