China patent intelligence API that delivers production-grade, normalized, English-translated patent data with entity disambiguation and citation graphs, sold to IP law firms and corporate R&D teams on
Every multinational doing FTO searches in China is either paying law firms a fortune or wrestling with raw CNIPA data themselves
Built for IP teams and patent research firms.
Chinese patent data is notoriously messy and under-served by Western IP databases, so being the clean structured layer is a durable moat

Why this is a gap
Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.
The market
IP teams and patent research firms need standardized, queryable Chinese patent data. Zero search volume and a recent hiring post (2 weeks old) suggest this is a niche, specialized problem being solved ad-hoc by individual engineers, not yet a standalone product market.
Competition & the opening
Patent databases like Google Patents and Espacenet exist but don't specialize in Chinese filings or real-time normalization. No named competitor suggests either no commercial product exists or the market is too small to sustain one. The gap is China-specific patent data pipelines with normalized schemas.
What's hard to build
Chinese patent filings use different naming conventions, character sets, and legal structures than Western patents; normalizing across these requires domain expertise and likely custom parsing logic. Accessing and scraping Chinese patent office (CNIPA) data at scale requires navigating potential IP restrictions, language barriers, and infrastructure blocked from Western regions.
Why now
Chinese patent data is poorly normalized and difficult to ingest at scale; demand is rising as Western IP teams monitor Asia.
