Zhihuiya Patent Forward Citation
This skill guides you on how to query patent forward citation data from the Zhihuiya patent database, helping users discover the patents and non-patent literature cited by specific patents during their application process.
Core Concepts
Forward citation refers to the patents and non-patent literature that a given patent has cited in its application documents. This is a fundamental aspect of patent analysis — understanding what prior art a patent references helps assess its novelty, scope, and technological lineage.
- Patent citations (
citedPatents): Other patents referenced by the queried patent.
- Non-patent literature citations (
citedOthers): Academic papers, technical reports, and other non-patent documents referenced by the queried patent.
Parameter Guide
You must provide at least one of the following two parameters. If both are provided, patentId takes priority.
| Parameter | Type | Required | Description |
|---|
| patentId | string | Conditionally | Patent ID(s). Multiple values separated by commas. Maximum 100 entries. |
| patentNumber | string | Conditionally | Publication/announcement number(s). Multiple values separated by commas. Maximum 100 entries. |
Rules:
- At least one of
patentId or patentNumber must be provided.
- If both are present,
patentId is used preferentially.
- Multiple values are separated by commas (English commas).
- Each parameter supports up to 100 entries per request.
Response Fields
| Field | Type | Description |
|---|
| total | integer | Total number of records returned |
| data | array | List of patent citation results |
| data[].patentId | string | Patent ID of the queried patent |
| data[].pn | string | Publication/announcement number |
| data[].citedPatents | array | List of cited patent documents |
| data[].citedOthers | array | List of cited non-patent literature |
| columns | array | Column definitions for rendering |
| costToken | integer | Tokens consumed by the query |
| type | string | Rendering style hint |
调用方式
- API 端点：
POST /zhihuiya/patentForwardCitation（完整参数/响应/错误码见 references/api.md）
- Python 脚本：
python scripts/zhihuiya_cited_references.py '<JSON 参数>' [--inline]
- 成本约束：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。
输出策略（脚本默认行为）：
- 始终将完整响应写入
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-zhihuiya-patent-forward-citation-<timestamp>.json（<cwd> 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；<session> 取自环境变量 SESSION_ID，按用户任务自动聚合；禁止写入 /tmp，当前目录不可写则报错）
- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如
total/costToken、最大列表字段的长度 + 前 3 条样本）
- 加
--inline 强制全量打印到 stdout（同样落盘）
读数据建议：先看摘要判断是否足够；需要具体字段时优先用 jq或ConvertFrom-Json 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。
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
Usage Examples
1. Query forward citations by publication number
Look up the forward citations for patent US10000000B2.
Parameters: {"patentNumber": "US10000000B2"}
2. Query forward citations for multiple patents
Find all citations for patents US10000000B2, US9876543B1, and EP3456789A1.
Parameters: {"patentNumber": "US10000000B2,US9876543B1,EP3456789A1"}
3. Query forward citations by patent ID
Retrieve the cited references for patent ID 12345678.
Parameters: {"patentId": "12345678"}
4. Query forward citations using both identifiers
Look up citations for patent ID 12345678 (publication number US10000000B2).
Parameters: {"patentId": "12345678", "patentNumber": "US10000000B2"} (patentId takes priority)
Display Rules
- Present data clearly: Show citation results in well-structured tables, separating patent citations from non-patent literature citations.
- Summarize counts: Always state the total number of cited patents and cited non-patent literature items.
- No fabrication: Only display data returned by the API. Do not infer or fabricate citation details.
- Error handling: When a query fails, explain the reason based on the error response and suggest the user verify their patent ID or publication number.
- Batch results: When querying multiple patents, organize results by patent so each patent's citations are clearly grouped.
- Empty results: If a patent has no citations, explicitly inform the user rather than showing an empty table.
User Expression & Scenario Quick Reference
Applicable -- Patent citation queries:
| User Says | Scenario |
|---|
| "What patents does XX cite" | Forward citation lookup |
| "Show me the references for patent XX" | Citation detail retrieval |
| "What prior art is cited by XX" | Prior art reference query |
| "List the cited literature for XX" | Non-patent literature lookup |
| "Citation analysis for patent XX" | Combined patent + literature citation |
| "What documents does patent XX reference" | General citation query |
Not applicable -- Needs beyond forward citation data:
- Backward/reverse citations (who cites this patent)
- Patent validity or legal status
- Patent family analysis
- Patent full-text search
- Patent classification or landscape analysis
积分消耗规则
按动态规则计费：消耗积分 = 81 × 返回data条数。每条为 1 条专利引证文献结果
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。
