New: 🇯🇵 Japan J-PlatPat · 特許商標意匠実用新案 (JPO) — Search Japan's patents, trademarks, designs & utility models as JSON

What it does

This actor searches the Japan Patent Office's J-PlatPat (INPIT) database across all four IP rights — patents, utility models, designs, and trademarks — and returns structured JSON. You get application and registration numbers, Japanese titles, applicants and inventors, IPC and Japan-specific FI classification codes, and filing/publication/registration dates instead of a manual portal session.

Who it's for

IP due-diligence teams, patent attorneys and paralegals, competitive-intelligence analysts monitoring Japanese filings, and product teams running freedom-to-operate checks before a JP launch.

Sample fields / output

title — 発明の名称 / 商標 / 意匠 (Japanese title)
applicant_names and inventor_names (arrays)
IPC_codes and FI_codes — international plus Japan's domestic File Index classification
application_date, publication_date, registration_date, status
search_type (patent / utility_model / design / trademark), document_url, optional priority_claim

Example use cases

IP due diligence — verify the patent estate of a Japanese acquisition target before signing the SPA.
Competitor monitoring — weekly sweeps of recent filings by named applicants (Toyota, Sony, Panasonic, SoftBank).
Freedom-to-operate — check that a product doesn't infringe live Japanese rights before launching in the JP market.
