Linkfox Eureka Claim Data

Eureka Patent Claim Data

This skill guides you on how to retrieve patent claim data via the Eureka patent platform, helping users quickly access the full claim text and claim count for one or more patents.

Core Concepts

The Eureka Claim Data tool returns the complete claims section for each queried patent:

1. Claims Array — The full text of all claims (independent and dependent) for the patent.
2. Claim Count — The total number of claims in the patent.
3. Related Patent Fallback — When replaceByRelated is enabled ("1"), if the requested patent has no claims data, the system will attempt to use a related patent (e.g., the granted version of an application) to provide claim data. The pnRelated field indicates which related patent was used.

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).

Parameter Guide

• If the user provides a publication number (e.g., CN115000000A, US11000000B2), use patentNumber.
• If the user provides an internal patent ID, use patentId.
• When both are supplied, patentId takes precedence.
• Set replaceByRelated to "1" when the user wants claim data even if the exact publication has none (common for application-stage patents).

Response Fields

Usage Examples

1. Retrieve claims for a single patent

Show me the claims for patent CN115000000A.

2. Get the claim count for a patent

How many claims does US11000000B2 have?

3. Batch-query claims for multiple patents

Get the claims for patents EP3000000A1 and CN115000001A.

4. Use related patent fallback for an application

Get the claims for application CN202210000000.0A — if claims aren't available, use the granted version.

5. Compare claims between patents

Show me the independent claims of US11000000B2 and US10000000B1 side by side.

Display Rules

1. Present claims clearly: Number each claim and preserve the hierarchical structure (independent vs. dependent claims).
2. Highlight independent claims: When the user is interested in the scope of protection, emphasize independent claims (typically claim 1 and any other independent claims).
3. Claim count summary: Always mention the total number of claims at the top of the response.
4. Related patent notice: If pnRelated is present, clearly inform the user that claims were sourced from a related patent and state which one.
5. Error handling: If the query fails or returns no results, explain the possible reasons (invalid patent number, patent not found, claims not yet published) and suggest alternatives (e.g., enabling replaceByRelated).
6. Long claims: For patents with many claims, consider showing a summary first (independent claims + total count) and offer to show all claims on request.

Important Limitations

• 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.
• Claims availability: Some early-stage application patents may not have claims published yet. Use replaceByRelated to attempt a fallback to a related patent.
• 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 claims:

Not applicable — Needs beyond patent claims:

• Patent bibliography/metadata retrieval (use the bibliography skill)
• Patent legal status queries
• Patent full-text description retrieval
• Patent search by keyword or classification
• Patent image/drawing search
• Patent family 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：
  • 下载 https://agent-files.linkfox.com/skills/linkfox-onboarding/release.zip，解压后安装这个skill。如需用户授权才可下载，要询问用户获得授权，你不能自己放弃下载。
• 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。
