Chinese Biopharma Patent Intelligence

See what China is patenting — as structured, machine-readable data

BioPattern extracts compound structures, applicants and competitive signals from Chinese pharmaceutical patents — the filings your current databases can't read — and delivers them as clean datasets, reports and an API.

245NLRP3-related CN patents indexed
120compound patents (C07D/C)

The China blind spot

Why global pharma misses half the competitive picture

Language barrier

Chinese patents are written in Mandarin. Most Western BD and CI teams rely on delayed, partial translations — or skip them entirely.

No structured access

Existing databases are built for humans, cost $50K+ per year, and offer no API. Compound structures inside Chinese filings stay locked in images.

Real decisions at stake

Competitive intelligence, license-in scouting and FTO analysis all have a China-shaped gap. That gap is where deals are lost.

First landscape: NLRP3 inflammasome inhibitors

One of immunology's hottest targets — fully mapped across Chinese filings

Multi-heterocycle systems dominate the scaffold distribution (C07D 401/471), fused N-heterocycles form the largest single family, and natural-product derivatives are a distinct Chinese niche. Full analysis in the report.

Built for four workflows

Competitive Intelligence

Track Chinese filings in your target area weekly. Spot new entrants, new scaffolds and family expansions before they surface in Western sources.

License-In Scouting

Identify licensable compounds from Chinese universities and biotechs, with structures and applicants already normalized for triage.

Freedom to Operate

Cover the Chinese flank of your FTO analysis. Avoid late-stage surprises from CN-only families invisible in English-language tools.

AI Drug Discovery

Stream deduplicated, validated structures into your models. Chinese patents add chemotypes absent from ChEMBL-class sources.

Engagement options

Start with a pilot. Scale when the data proves itself.
