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:
- Identification — Patent ID (
patentId) and publication number (pn). - Title & Abstract — Multi-language invention titles (
inventionTitle) and abstracts (abstracts). - Patent Type — One of APPLICATION, PATENT, UTILITY, or DESIGN.
- Parties — Original applicants (
applicants), current assignees (assignees), inventors (inventors), patent agents (agents), filing agency (agency), and examiners (examiners). - Dates & References — Application reference, publication reference, dates of public availability, and estimated expiry date (
exdt). - Classifications — IPC-R (
classificationIpcr), CPC (classificationCpc), UPC (classificationUpc), GBC (classificationGbc), Locarno (classificationLoc), FI (classificationFi), F-term (classificationFterm). - Citations & Related Documents — Cited patents (
referenceCitedPatents), cited non-patent literature (referenceCitedOthers), and related documents such as divisionals/continuations (relatedDocuments). - 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
| Parameter | Required | Description |
|---|---|---|
| patentId | Conditionally | Patent ID. At least one of patentId or patentNumber must be provided. Comma-separated for multiple values, up to 100. |
| patentNumber | Conditionally | Publication (announcement) number. At least one of patentId or patentNumber must be provided. Comma-separated for multiple values, up to 100. |
- 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,
patentIdtakes precedence.

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
- 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.
- 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.
- Classification codes: Format IPC/CPC/UPC codes clearly. When the user is looking at technology domains, provide the top-level description when possible.
- Dates: Convert integer timestamps to human-readable date formats (YYYY-MM-DD).
- 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.
- 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
patentIdorpatentNumbermust be provided; the request will fail if both are empty. - Patent ID priority: When both
patentIdandpatentNumberare provided, the system usespatentIdand ignorespatentNumber. - 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:
| User Says | Scenario |
|---|---|
| "Show me the basic info for patent XX" | Full bibliography retrieval |
| "Who are the applicants/inventors of XX" | Party information lookup |
| "What classifications does patent XX have" | Classification query |
| "Get the title and abstract for these patents" | Batch title/abstract query |
| "When does this patent expire" | Expiry date check |
| "What patents does XX cite" | Cited references query |
| "Is this a utility or design patent" | Patent type check |
| "Show the priority claims for XX" | Priority information lookup |
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
解决认证和积分问题
发生以下异常情况时，采用以下措施来处理：
异常情况
- 未配置API Key：环境变量未配置
LINKFOX_AGENT_API_KEY，也未配置LINKFOXAGENT_API_KEY。 - 响应401或402状态码
- 响应提示积分或余额不足：消息含"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。
措施
- 优先采用skill内的 onboarding.md 引导解决问题。
- 如找不到 onboarding.md 文件，则加载 /linkfox-onboarding 这个skill并根据它的引导来处理。如未安装请先安装：
- 兜底措施：仅当前面两个措施经过所有努力都走不通时，才提示用户依据 https://skill.linkfox.com/linkfoxskills/guide.htm 指引获取API Key，或去 https://os.linkfox.com/ 补充积分。
积分消耗规则
按动态规则计费：消耗积分 = 81 × max(返回条数, 1)。
重要：本技能的服务按倍数动态计算，可能一次性消耗大量积分，必须提醒用户，由用户决定是否继续。
