## Who this is for

* Developers and AI engineers building patent search agents, IP copilots, or
  R&D intelligence tools (LangChain, Claude, Cursor, etc.)
* IP and legal teams needing programmatic access to FTO, prior art, and
  landscape workflows
* Life sciences and biopharma researchers running drug/target discovery and
  patent mapping
* Materials and chemistry researchers searching prior art on chemical
  structures and molecular compositions
* Data and product teams integrating patent or R&D intelligence into internal
  systems

## Core data domains

* **Patent:** 210M+ records across 174 jurisdictions (daily refresh) —
  USPTO, EPO, WIPO, CNIPA, and all major global authorities
* **Scientific literature:** 216M+ papers, unified search with patents in
  a single query
* **Life sciences and pharma:** 1.2M+ clinical trials, drugs, targets, and
  1.4B+ biological sequences
* **Chemistry:** 281M+ chemical structures, exact/substructure/similarity search
* **Company and innovation:** Assignee portfolios, R&D trends, technology
  landscape signals

## REST API capabilities

Data APIs cover patent search, metadata, legal status, valuation, analytics,
literature, life sciences, drug data, and chemical structure search.

AI APIs cover novelty search, FTO analysis, specification drafting, technical
Q&A, materials solution exploration, design infringement detection, and
bio-pharma Q&A.

## MCP capabilities

MCP servers cover patent search and retrieval, patent analytics and strategy,
legal status and valuation, life sciences, chemistry, and enterprise connectors.
Compatible with Claude, Cursor, Windsurf, and any MCP-compatible client.

New developers receive 10,000 free credits. No credit card required.
