Description¶
A provisional patent application was filed with the United States Patent and Trademark Office on 2026-02-24 for:
"System and Method for Process Ancestry Chain-Scoped Endpoint Security Enforcement Utilizing a Two-Tier Evaluation Engine with In-Memory Ancestry Acceleration"
The application covers the two-tier evaluation engine (fast-path in-memory ancestry lookup + full graph query fallback), the process ancestry chain scoping mechanism, and the in-memory PID index acceleration structure.
On 2026-02-25, a cryptographic archival preservation was performed:
