Al Macdonald holds 23 US patents covering the core technical challenges of compliance infrastructure: screening, entity resolution, search and matching, risk data systems, and monitoring workflows.
The portfolio is described thematically above. Selected issued patents and published applications are listed below.
Patents in this group address the core problem of sanctions and watchlist screening — matching entities against regulated lists at scale, handling name variations, transliterations, and partial data. The inventions cover screening architectures designed for high-volume, low-latency environments where false negatives carry regulatory consequence.
Entity resolution is the problem of determining whether two records refer to the same real-world person or organization. These patents address disambiguation at scale — resolving identity across incomplete, inconsistent, and transliterated data. The work covers both algorithmic approaches and data structures designed for compliance-grade precision.
Search in compliance contexts is not keyword retrieval — it requires fuzzy matching, phonetic equivalence, and ranked relevance across structured and unstructured data. Patents in this group cover search architectures and matching algorithms built specifically for the ambiguity and precision demands of compliance and risk workflows.
These patents address the infrastructure for collecting, structuring, and serving risk-relevant data — sanctions lists, adverse media, ownership structures, and related datasets. The inventions cover data pipeline design, update propagation, and the systems that make risk data reliable and current at the point of screening.
Compliance is not a one-time check — it requires ongoing monitoring of entities against changing lists and emerging risk signals. Patents in this group cover the workflow systems and monitoring architectures that keep compliance programs current, including alert management, case handling, and audit trail design.
