Zhihuiya Patent PDF Downloader
This skill guides you on how to retrieve patent PDF full-text download links from the Zhihuiya patent database, supporting lookup by patent ID or publication number.
Core Concepts
The Zhihuiya Patent PDF service provides direct download links to the full-text PDF documents of patents worldwide. You can query by patent ID or publication number (also called public announcement number), and retrieve up to 100 patents in a single request.
Lookup priority: When both patentId and patentNumber are supplied, the service uses patentId first. This is important to remember when both identifiers are available.
Family substitution: If a patent's own PDF is unavailable, the service can optionally return the PDF of a related family patent instead.
Parameter Guide
| Parameter | Type | Required | Description |
|---|
| patentId | string | Conditionally | Patent ID(s). At least one of patentId or patentNumber must be provided. Separate multiple values with commas. Max 100 entries. |
| patentNumber | string | Conditionally | Publication/announcement number(s). At least one of patentId or patentNumber must be provided. Separate multiple values with commas. Max 100 entries. |
| replaceByRelated | string | No | Whether to substitute with a family patent PDF when the original is unavailable. 1 = yes, 0 = no. Defaults to no substitution. |
How to Choose the Right Identifier
- Patent ID (
patentId): An internal numeric identifier within the Zhihuiya system. Use this when the user provides Zhihuiya-specific IDs.
- Publication Number (
patentNumber): The public-facing patent number (e.g., US20230012345A1, CN115000000A). Use this when the user provides standard patent numbers.
Response Fields
| Field | Description |
|---|
| total | Number of records returned |
| data | Array of patent objects, each containing download information |
| data[].patentId | The patent ID |
| data[].pn | The publication/announcement number |
| data[].pdfPath | The PDF full-text download URL |
| data[].pnRelated | Publication number of the substitute family patent (only present when family substitution is used) |
| costToken | Tokens consumed by the request |
调用方式
- API 端点：
POST /zhihuiya/pdfData（完整参数/响应/错误码见 references/api.md）
- Python 脚本：
python scripts/zhihuiya_pdf_data.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-pdf-data-<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. Single Patent by Publication Number
Retrieve the PDF for patent publication number US20230012345A1.
Parameters: {"patentNumber": "US20230012345A1"}
2. Multiple Patents by Publication Number
Download PDFs for CN115000000A, CN115000001A, and CN115000002A.
Parameters: {"patentNumber": "CN115000000A,CN115000001A,CN115000002A"}
3. Single Patent by Patent ID
Get the full-text PDF for patent ID 12345678.
Parameters: {"patentId": "12345678"}
4. With Family Substitution Enabled
Download the PDF for EP4000000A1. If it is unavailable, use a family patent PDF instead.
Parameters: {"patentNumber": "EP4000000A1", "replaceByRelated": "1"}
5. Batch Download by Patent IDs
Retrieve PDFs for patent IDs 11111111, 22222222, 33333333.
Parameters: {"patentId": "11111111,22222222,33333333"}
Display Rules
- Present download links clearly: For each patent, show the publication number and its PDF download link in a clean table or list format.
- Highlight substitutions: If a PDF was provided via family patent substitution, explicitly note this and show the
pnRelated value so the user knows which family patent was used.
- Batch results: When multiple patents are returned, present them in a table with columns: Publication Number, Patent ID, PDF Link, and Substitution Note (if applicable).
- Error handling: When a query fails or returns no results, explain the reason and suggest the user verify the patent ID or publication number. If
replaceByRelated was not enabled, suggest enabling it as an alternative.
- No PDF available: If a patent entry is returned without a
pdfPath, inform the user that the PDF is not available and suggest enabling family substitution.
Important Limitations
- Batch limit: A maximum of 100 patents per request.
- Identifier requirement: At least one of
patentId or patentNumber must be provided; the request will fail if both are empty.
- Priority rule: When both identifiers are provided,
patentId takes precedence over patentNumber.
- PDF availability: Not all patents have PDFs available. Use the
replaceByRelated option to fall back to family patents.
User Expression & Scenario Quick Reference
Applicable -- Patent PDF document retrieval tasks:
| User Says | Scenario |
|---|
| "Download the PDF for patent XX" | Single patent PDF retrieval |
| "Get full-text documents for these patents" | Batch patent PDF download |
| "I need the PDF for publication number XX" | Lookup by publication number |
| "Can I get the patent document even if it's not directly available" | Family substitution scenario |
| "Batch export patent PDFs" | Multi-patent batch download |
Not applicable -- Needs beyond patent PDF retrieval:
- Patent search or discovery (finding patents by keyword, assignee, etc.)
- Patent citation or legal status analysis
- Patent claim interpretation or translation
- Patent portfolio analytics or landscape mapping
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 PDF 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。
