U.S. Patent Application No. 19/640,793 — Track One Prioritized Examination · Claims subject to amendment during examination · Licensing

License the framework for cached-executable security across policy transitions.

StaamlCorp operates a single-portfolio licensing program for temporal security discontinuities — a class of vulnerability where cached executable content persists across security policy transitions. Validated by Apple. Applicable across platforms. Licensed on fair and reasonable terms.

Discovery and validation

In 2025, founder Stanley Lee Linton identified a previously undocumented class of vulnerability — designated LDB-01 — in which cached executable content persisted across security policy transitions. Apple reproduced and remediated their instance; StaamlCorp patented the generalized framework.

The finding

Cached WebAssembly modules, JavaScript blobs, and Service Worker scripts cached during standard operation remained executable after iOS Lockdown Mode activation — one concrete instance of cached-executable persistence across a policy transition.

Apple validation

Reported to Apple Security. Apple reproduced the vulnerability, assigned CVE reference webkit-294380, and shipped a fix in iOS 26 and iPadOS 26. Apple’s response acknowledged the work as security-beneficial research warranting recognition.

Generalized framework

The underlying class — cached executables surviving a security policy change — appears wherever those two conditions coexist. StaamlCorp's patent claims cover the generalized detection-and-mitigation framework, not any single vendor's product.

Patent-Pending Technology — Licensing Available

StaamlCorp's utility patent covers the complete, platform-independent framework for detecting and mitigating cached executable persistence across security policy transitions.

U.S. Patent Application No. 19/640,793

Title: System and Method for Mitigating Cached Executable Persistence Across Security Policy Transitions

Status: Pending — Track One Prioritized Examination · Claims subject to amendment

Claims: 30 total (4 independent, 26 dependent)

Coverage: 7+ content types, 6+ cache locations, 7+ platforms, all policy transition types

Framework scope

The pending claims describe a complete loop: detecting a security policy transition, evaluating cached executable content under the new policy, and mitigating non-compliant items with an audit trail.

Validated by Apple

The underlying vulnerability class was independently reproduced and remediated by Apple Inc. — CVE webkit-294380, fixed in iOS 26 and iPadOS 26.

Cross-Platform Scope

Patent claims cover iOS, Android, Windows, macOS, Linux, embedded systems, autonomous AI agents, browsers, enterprise MDM, and cloud/container environments.
