Zhihuiya Patent Expression Search

This skill searches the Zhihuiya (PatSnap) patent database using an Analytics query expression (e.g. TACD: virtual reality), returning a list of matching patents with their patent IDs and publication numbers, plus the total hit count.

Core Concepts

Expression-based patent search uses Zhihuiya's Analytics query syntax to retrieve patents matching a field-scoped boolean expression. Unlike image-based search, this is a text query against the full patent corpus.

Query expression (queryText) holds an Analytics expression. Common field-scoped syntax:

Syntax	Scope
`TACD: <term>`	Title + Abstract + Claims + Description
`TAC: <term>`	Title + Abstract + Claims
`TA: <term>`	Title + Abstract
`AND` / `OR` / `NOT`	Boolean operators (combine terms/fields)

This skill returns a list of patents (patentId + pn). To retrieve detailed bibliographic data, full text, legal status, family, or images for a specific patent, feed the returned patentId/pn into the corresponding linkfox-zhihuiya-bibliography / linkfox-zhihuiya-simple-bibliography / linkfox-zhihuiya-legal-status / linkfox-zhihuiya-patent-family skills.

Data Fields

Each data[] item (one matching patent):

Field	Description
patentId	Zhihuiya internal patent ID
pn	Publication (announcement) number
title	Patent title
apdt	Application date (integer, YYYYMMDD)
pbdt	Publication date (integer, YYYYMMDD)
apno	Application number
authority	Patent office / authority (e.g. `US`)
inventor	Inventor(s), pipe-separated
originalAssignee	Original applicant(s), pipe-separated
currentAssignee	Current assignee(s), pipe-separated

Top-level fields:

Field	Description
data	专利列表（每项含上表 10 个字段）
total	Number of records returned in this response
allRecordsCount	Total hits matching the query expression
costToken	Token cost for this query
columns	Render metadata (display hints, not data records)
type	Render style (e.g. `tableListWorkbenches`)
errcode	`200` on success
errmsg	`ok` on success

The top-level columns array is render metadata and may be longer than the real data list — do not treat it as data.

调用方式

API 端点：POST /zhihuiya/querySearchPatent（完整参数/响应/错误码见 references/api.md）
Python 脚本：python scripts/zhihuiya_query_search_patent.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、翻页或改检索式连续试探；需要继续检索或翻页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-retrieval-patent-search-<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
响应提示积分或权限不足：消息含"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/No permission/API package quota/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。

Parameter Guide

Parameter	Required	Default	Description
queryText	Yes	-	Analytics 检索式，最大 12000 字符
limit	No	10	返回专利个数，1–1000
offset	No	0	偏移量，0–19999；`limit + offset` ≤ 20000
sort	No	-	排序数组，元素 `{field, order}`
stemming	No	0	截词检索：`1` 开启 / `0` 关闭，默认关闭
collapseType	No	ALL	去重方式：ALL / APNO / DOCDB / INPADOC / EXTEND
collapseBy	No	-	去重排序字段：APD / PBD / AUTHORITY / SCORE
collapseOrder	No	-	去重排序顺序：OLDEST / LATEST
collapseOrderAuthority	No	-	受理局优先级数组（仅 `collapseBy=AUTHORITY` 时有效），按输入顺序保留对应专利

Sort object

`field`	Meaning
PBDT_YEARMONTHDAY	Publication date
APD_YEARMONTHDAY	Application date
ISD	Issue / grant date
SCORE	Query relevance

order: DESC or ASC. Example: [{"field":"SCORE","order":"DESC"}].

Collapse (deduplication)

`collapseType`	Description
ALL	No dedup
APNO	By application number
DOCDB	By simple family
INPADOC	By INPADOC family
EXTEND	By PatSnap extended family

collapseBy selects which representative record to keep (APD/PBD/AUTHORITY/SCORE); collapseOrder picks OLDEST or LATEST.

Usage Examples

1. Basic expression search

检索 TACD: virtual reality 的专利，返回 10 条

Action: {"queryText": "TACD: virtual reality", "limit": 10}

2. Sort by relevance

用检索式 TACD: drone AND camera 查专利，按相关性排序

Action: {"queryText": "TACD: drone AND camera", "sort": [{"field": "SCORE", "order": "DESC"}]}

3. Paginate

翻到第 2 页，每页 10 条

Action: {"queryText": "TACD: virtual reality", "offset": 10, "limit": 10}

4. Dedup by DOCDB family

检索 TACD: virtual reality，按简单同族去重，保留最新

Action: {"queryText": "TACD: virtual reality", "collapseType": "DOCDB", "collapseBy": "APD", "collapseOrder": "LATEST"}

Display Rules

Present results as a table: show pn, title, apdt/pbdt (format as dates), inventor, currentAssignee, authority per item.
Show totals: always state allRecordsCount (total hits) and the current page range (offset–offset+limit).
Default sort: if the user does not specify a sort, actively inject {"field": "SCORE", "order": "DESC"} so results are relevance-ordered; respect any sort the user explicitly requests.
Large result sets: present a summary table first, note the total, and offer to expand specific patents.
Expand via sibling skills: to get full metadata for a patent, direct the user to linkfox-zhihuiya-bibliography / linkfox-zhihuiya-simple-bibliography; do not re-query this search skill for details.
No fabrication: only display fields actually present in the response; never invent titles, dates, or assignees not returned.

Important Limitations

queryText is required and must be a valid Analytics expression. Missing it returns errcode 400.
Paging ceiling: limit + offset must be ≤ 20000; limit max 1000; offset max 19999.
List-only output: this skill returns patentId + pn (and basic fields). Full bibliographic/full-text/legal data must be fetched via dedicated linkfox-zhihuiya-* skills.
No auto-retry on empty/error: if the query returns no hits or an error, do not automatically swap keywords or rewrite the expression; confirm with the user first (each call costs credits).
Permission/quota: a 501 "No permission or API package quota" response means the current key lacks the query-search permission/quota. This is a permission/package issue (not merely low balance) and cannot be resolved by recharging alone — do not retry; surface it to the user to open/enable the query-search API package.

User Expression & Scenario Quick Reference

Applicable — Find patents by query expression:

User Says	Scenario
"检索 TACD: virtual reality 的专利"	Basic expression search
"用检索式查虚拟现实相关专利"	Expression search
"检索式：TAC AND camera"	Boolean expression
"按公开日排序检索"	Sorted search
"按简单同族去重"	Deduplicated search
"翻到第 2 页"	Pagination

Not applicable — Needs beyond expression search:

Bibliographic detail of a known patent ID/number (use linkfox-zhihuiya-bibliography)
Image-based patent search (use linkfox-zhihuiya-patent-image-search)
Legal status / family / full-text / PDF (use dedicated linkfox-zhihuiya-* skills)

Boundary judgment: When the user already has a patent ID or publication number and wants its metadata → use the bibliography skill. When the user wants to discover patents matching a query expression → this skill.

积分消耗规则

按动态规则计费：消耗积分 = 3 × 返回data条数。每条为 1 条检索式检索专利结果

重要：本技能的服务按倍数动态计算，返回条数越多消耗越大，必须提醒用户，由用户决定是否继续。优先用较小的 limit 验证检索式命中，确认后再决定是否扩大范围或翻页。
