1 canonical article. Procopio is named inventor on the Topic Authority patent (US 8,458,196). The system computes per (author, topic) authority signatures: for each document d the author contributed to, sum (authorship% * topic_weight); aggregate across all the author's documents to produce a per-author per-topic expertise score. The mathematical quantification of "this person is an authority on this topic," structurally the basis for the E-A-T Expertise signal at the author level. Connects to Agent Rank (US 7,565,358, 65gp pat-47, the earlier Google author-reputation patent) and to Overwijk's site-topical-authority (US 20210004416) to form a layered authority model.

Each inventor track inside the Nizam SEO War Room patents archive isolates one engineer's research arc — typically a decade or more of continuations, divisionals, and follow-up patents on a coherent research thread. Reading by inventor (rather than by topic) recovers the narrative: how the original disclosure evolved, what the continuations added, which claims got carved out into divisional applications, and how the thread eventually intersected with other research lines at Google or Microsoft. This is how working SEOs build durable intuition about search-engine internals — not by memorizing claim language, but by following the research bibliography that shipped the algorithms we now optimize against.
How to read this track
Start with the earliest filing — it sets the foundational disclosure. Continuations refine the claims; divisional applications split out separable inventions; the follow-up patents tend to introduce performance optimizations, edge-case handling, or downstream integration with other systems. Each patent on this site is annotated with the ranking surface it touches — query understanding, document retrieval, ranking, behavioral signals, knowledge graph, or AI search — so the practitioner can map the research back to the algorithm output observed on live SERPs.
