Verified Feasibility

Beyond mere concepts. Every technology featured has been examined and granted by the Japan Patent Office (JPO). You are looking at structurally sound, legally rigorously-tested engineering, not just theoretical ideas.

Business-Ready Analysis

We translate technical jargon into business value. Our AI models extract the core utility of each patent, estimating addressable markets (TAM) and identifying direct applications for your industry.

Strategic Tech Scouting

Stay ahead of the curve. Use our database to monitor emerging Japanese tech trends, find foundational IP for inspiration, or identify potential R&D partners before your competitors do.

Every patent here was granted by the Japan Patent Office, examined under one of the world's most rigorous prosecution standards, and represents a verified technical foundation to accelerate your innovation roadmap.

DigPatent Database — 2,599 patents, verified August 2026

DigPatent curates high-impact Japanese technologies. The current collection centers on dormant patents — inventions that cleared JPO examination but are not currently commercialized: verified engineering whose market opportunity remains unclaimed. Each one has been analyzed by AI from the perspective of an R&D executive: what does it actually do, who needs it, and what would it cost to bring to market? The result is not a patent database. It is an intelligence platform.


Our AI pipeline reads the original Japanese patent claims and prosecution history, then generates English-language intelligence reports calibrated for non-attorneys — market sizing, competitive positioning, integration roadmaps, and go-to-market risk. We do not translate legal text. We translate technical value into business decisions.


Every market estimate is generated by AI and marked accordingly. Every structural fact — filing dates, registration numbers, remaining life — comes directly from JPO records. We hold ourselves to the same sourcing standard we would demand from a consultant.

Every analyzed patent includes a complete English-language technology intelligence report — market sizing, competitive positioning, integration roadmap, and go-to-market strategy. Built for R&D directors who need decisions, not documents.
