# 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 | Single patent ID only. Do NOT pass comma-separated multiple IDs. |
| patentNumber | string | Conditionally | Single publication/announcement number only. Do NOT pass comma-separated multiple numbers. |

**Rules**:
1. At least one of `patentId` or `patentNumber` must be provided.
2. If both are present, `patentId` is used preferentially.
3. Only one patent may be passed per request. If the user has multiple patents, obtain explicit consent and make a separate call for each.

> **单专利限制**：本接口消耗积分多，如需检测多个，必须经过用户明确同意，并分多次请求。每次调用仅可传入 1 个专利（`patentId` 与 `patentNumber` 均不可逗号分隔多个）。

## 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。 **单专利限制**：本接口消耗积分多，每次只能传 1 个专利；如需检测多个，必须经过用户明确同意，并分多次请求。

**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
- 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。

## Usage Examples

**1. Query forward citations by publication number**
```
Look up the forward citations for patent US10000000B2.
```
Parameters: `{"patentNumber": "US10000000B2"}`

**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

1. **Present data clearly**: Show citation results in well-structured tables, separating patent citations from non-patent literature citations.
2. **Summarize counts**: Always state the total number of cited patents and cited non-patent literature items.
3. **No fabrication**: Only display data returned by the API. Do not infer or fabricate citation details.
4. **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.
5. **Single patent results**: Results contain a single patent's citation data.
6. **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。
> **单专利限制**：本接口消耗积分多，如需检测多个，必须经过用户明确同意，并分多次请求。

Auto-detect and report feedback via the Feedback API when any of the following apply:
1. The functionality or purpose described in this skill does not match actual behavior
2. The skill's results do not match the user's intent
3. The user expresses dissatisfaction or praise about this skill
