Eureka Patent Bibliography

This skill guides you on how to retrieve patent bibliography (bibliographic) information via the Eureka patent platform, helping users quickly obtain structured metadata for one or more patents — including titles, abstracts, applicants, inventors, classifications, priority claims, cited references, and more.

Core Concepts

The Eureka Bibliography tool returns comprehensive bibliographic data for each patent, organized into several categories:

1. Identification — Patent ID (patentId) and publication number (pn).
2. Title & Abstract — Multi-language invention titles (inventionTitle) and abstracts (abstracts).
3. Patent Type — One of APPLICATION, PATENT, UTILITY, or DESIGN.
4. Parties — Original applicants (applicants), current assignees (assignees), inventors (inventors), patent agents (agents), filing agency (agency), and examiners (examiners).
5. Dates & References — Application reference, publication reference, dates of public availability, and estimated expiry date (exdt).
6. Classifications — IPC-R (classificationIpcr), CPC (classificationCpc), UPC (classificationUpc), GBC (classificationGbc), Locarno (classificationLoc), FI (classificationFi), F-term (classificationFterm).
7. Citations & Related Documents — Cited patents (referenceCitedPatents), cited non-patent literature (referenceCitedOthers), and related documents such as divisionals/continuations (relatedDocuments).
8. PCT Data — PCT or regional filing data and publishing data.

Patent identification: Patents can be looked up by either patent ID or publication number. When both are provided, patent ID takes priority. Multiple values can be submitted in a single request (comma-separated, up to 100).

Parameter Guide

• If the user provides a publication number (e.g., CN115000000A, US11000000B2, EP3000000A1), use patentNumber.
• If the user provides an internal patent ID, use patentId.
• When both are supplied, patentId takes precedence.

Response Fields

Usage Examples

1. Retrieve basic info for a single patent

Show me the bibliography for patent CN115000000A.

2. Get applicants and inventors for a patent

Who are the applicants and inventors of US11000000B2?

3. Batch-query bibliographic data for multiple patents

Get the titles, abstracts, and classification for patents EP3000000A1, CN115000001A, and JP2022000001A.

4. Check priority claims and related documents

What are the priority claims and related documents for patent US11000000B2?

5. Look up patent expiry date

When does patent CN115000000A expire?

6. Retrieve patent agent and examiner information

Who is the patent agent and examiner for CN115000000A?

Display Rules

1. Present data clearly: Show results in a well-structured format. For single patents, use labeled sections. For multiple patents, use a summary table with key fields and expand details as needed.
2. Title and abstract: Display the title and abstract in the language most relevant to the user. If multiple languages are available, show the user's preferred language first, with the original language in parentheses if different.
3. Classification codes: Format IPC/CPC/UPC codes clearly. When the user is looking at technology domains, provide the top-level description when possible.
4. Dates: Convert integer timestamps to human-readable date formats (YYYY-MM-DD).
5. Error handling: If the query fails or returns no results, explain the possible reasons (invalid patent number format, patent not found in database) and suggest the user double-check the input.
6. Volume notice: When querying many patents, present a summary table and note the total count returned.

Important Limitations

• Up to 100 patents per request: The maximum number of patent IDs or publication numbers in a single call is 100.
• At least one identifier required: Either patentId or patentNumber must be provided; the request will fail if both are empty.
• Patent ID priority: When both patentId and patentNumber are provided, the system uses patentId and ignores patentNumber.
• Data coverage: Results depend on the Eureka patent database coverage; some very recent filings may not yet be reflected.

User Expression & Scenario Quick Reference

Applicable — Queries about patent bibliographic/metadata information:

Not applicable — Needs beyond patent bibliography:

• Patent legal status queries (use the legal-status skill)
• Patent full-text claims or description retrieval
• Patent search by keyword or classification
• Patent image/drawing search
• Patent family analysis
• Freedom-to-operate (FTO) analysis
