Overview
Approximate patent/prior-art landscape for a topic, built from published technical prior art rather than a patent-office filing search: arXiv full-text search results, a web search scoped to filings and patent news, and a research brief tying it together, in one call. Composite: one call runs arxiv-search + search in parallel (both required together — the call only fails if both fail) plus research-brief as an optional third leg. Not a patent-office prior-art search or freedom-to-operate opinion
