Eureka Patent Image Search (Single Image)

This skill guides you on how to perform patent image search (search-by-image) via the Eureka patent platform. Given a single image URL, it finds visually similar patents in the design or utility patent databases, supporting multiple search models and extensive filtering options.

Core Concepts

The Eureka Patent Image Search tool enables visual similarity search across patent databases:

1. Search Models — Four models are available depending on the patent type and search intent:

   • Model 1: Design smart association — finds design patents with intelligent visual association
   • Model 2: Design search this image — exact visual match for design patents
   • Model 3: Utility match shape — matches utility patents by shape/contour
   • Model 4: Utility match shape + pattern + color — matches utility patents by shape, pattern, and color combined

2. Patent Types — Two patent types are supported:

   • D (Design) — search within design/industrial design patents (use models 1 or 2)
   • U (Utility) — search within utility model patents (use models 3 or 4)

3. Filtering — Extensive optional filters for country/authority, Locarno classification, date ranges, legal status, assignees, and keyword fields.
