Value proposition
World's first AI-native patent research platform powered by PlutoLM — a patent-specialized LLM trained on 170M+ global patents (250B sentences + 1.6B drawings) from 106 countries, enabling natural-language patent search, automated technology trend reports in 10 minutes, and enterprise-grade IP analytics that replaces traditional complex query-based systems.
Products and solutions
Keywert (AI patent search engine), Keywert Insight (AI-native patent research platform with natural language interface), PlutoLM (patent-specialized LLM), IP Data Intelligence (big data consulting), IP KingKong (AI patent translation platform), PatSpoon (patent education platform), Keywert DataGrid (AI-Ready structured patent data), Wert DataGrid, Signal, Decision, Intelligence Analysis
Unique value
Only company with a patent-domain-specific LLM (PlutoLM) trained on 170M+ patents with 250B sentences, combined with AI-Ready structured patent data (DataGrid) and on-premise deployment via Rebellions NPU — offering the deepest domain-specific AI for IP research in Korea, competing against global incumbents like Clarivate and Anaqua.
Target customer
Enterprise IP centers, R&D departments, patent law firms, universities, and government agencies — primarily large Korean conglomerates (Hanwha, LG, SK, Hyundai Motor, Celltrion) and 3,000+ cumulative corporate customers
Industries served
Intellectual Property / Patents, Legal Tech, R&D, Manufacturing, Pharmaceuticals & Biotech, Chemicals, Electronics & Semiconductors
Technology advantage
PlutoLM — patent-domain LLM trained on 170M+ patents (250B sentences + 1.6B drawings) from 106 countries; PAT-BERT (2022) predecessor model; AI-Ready Data pipeline with 11 proprietary data refinement stages; ISO 27001 & 27017 certified; tenant-level data isolation; on-premise deployment via Rebellions NPU (ATOM-Max) partnership; 21 registered patents; keyValue patent grading system
How they differentiate
Unlike global incumbents (Clarivate, Anaqua, Questel) that offer general IP databases, WRT Intelligence built a patent-specific LLM (PlutoLM) from scratch, enabling natural-language queries instead of complex search syntax. Their AI-Ready Data pipeline structures 170M+ patents for direct AI consumption, reducing hallucination risk. On-premise deployment via Korean NPU (Rebellions) addresses enterprise security needs. Korean-language optimized workflow tailored to domestic chaebol IP practices.
