# Zhihuiya Patent Image Search

This skill guides you on how to perform image-based patent similarity searches using the Zhihuiya patent database, helping users identify potentially similar **design patents**. This skill supports design patents only; for utility model patents use `linkfox-zhihuiya-utility-patent-image-search`.

## Core Concepts

**Patent Image Search** uses visual AI models to compare a given product or design image against a global patent image database. It returns a ranked list of similar patents, enabling users to evaluate infringement risks or conduct prior-art research.

**This skill supports design patents only:**

| Type | Code | Description |
|------|------|-------------|
| Design Patent | `D` | Protects the ornamental appearance of a product |

**Search models** for design patents:

| Model ID | Strategy | Recommendation |
|----------|----------|----------------|
| 1 | Intelligent Association | Recommended for design patents (default) |
| 2 | Search This Image | Exact visual match |

> Utility model patents (model 3/4) are not supported by this skill. Use `linkfox-zhihuiya-utility-patent-image-search` instead.

**Scoring logic**: A higher `score` value means greater visual similarity. When presenting results, sort by score in descending order (highest similarity first) so users can prioritize the most relevant patents for review.

## 调用方式

- **API 端点**：`POST /zhihuiya/patentImageSearch`（完整参数/响应/错误码见 `references/api.md`）
- **Python 脚本**：`python scripts/zhihuiya_patent_image_search.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-image-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。

## Local Image Upload

This tool requires a **publicly accessible image URL**. If the user provides a local image file path (e.g., `C:\Users\...\photo.png`, `/home/.../image.jpg`), you must upload it first to obtain a public URL.

Run the upload script:
```bash
python scripts/upload_image.py /path/to/local/image.png
```

The script will return a public URL (valid for 24 hours) that can be used as the image URL parameter.

## Usage Examples

**1. Basic design patent search (recommended starting point)**
Search for design patents similar to a product image across all countries:
```json
{
  "url": "https://example.com/my-product.jpg",
  "patentType": "D",
  "model": 1,
  "limit": 20
}
```

**2. Design patent search limited to specific countries**
Search only in China and the United States:
```json
{
  "url": "https://example.com/my-product.jpg",
  "patentType": "D",
  "model": 1,
  "country": "CN,US",
  "limit": 20
}
```

**3. Search with Locarno classification filter**
Narrow results to a specific product category (e.g., LOC 07-01 for tableware):
```json
{
  "url": "https://example.com/my-product.jpg",
  "patentType": "D",
  "model": 1,
  "loc": "07-01",
  "preFilter": 1,
  "limit": 20
}
```

**4. Search only active patents within a date range**
Find active design patents filed after 2020:
```json
{
  "url": "https://example.com/my-product.jpg",
  "patentType": "D",
  "model": 1,
  "simpleLegalStatus": "1",
  "applyStartTime": "20200101",
  "limit": 30
}
```

**5. Search by specific assignee**
Find patents held by a particular company:
```json
{
  "url": "https://example.com/my-product.jpg",
  "patentType": "D",
  "model": 1,
  "assignees": "Apple Inc.",
  "limit": 20
}
```

**6. Get results with Chinese-translated titles**
```json
{
  "url": "https://example.com/my-product.jpg",
  "patentType": "D",
  "model": 1,
  "lang": "cn",
  "limit": 20
}
```

## Display Rules

1. **Sort by score**: Always sort results by `score` in descending order (highest similarity first) to help users quickly identify the most relevant infringement risks.

2. **Show complete details**: When summarizing results or generating reports, include ALL of the following for each patent -- do NOT omit or abbreviate:
   - Application number (`apno`)
   - Patent title in Chinese (use `lang: cn` or provide translation)
   - Inventor (`inventor`)
   - Patent drawing (the matched `url` image)
   - **Every** patent image in the image list
   - Patent abstract
   - Patent description
   - LOC classification information (`loc`)
   - Radar result (`radarResult`) if available
   - Patent specification

3. **Legal disclaimer**: Always append a friendly reminder at the end of results:
   > This search result was generated by LinkfoxAgent. It is recommended to consult a professional patent attorney for legal advice.

4. **Score explanation**: Remind users that the score represents visual similarity -- a higher score indicates a closer match, but does not constitute a legal determination of infringement.

5. **Pagination guidance**: When the total count exceeds the returned results, inform users about the total number of matching patents and guide them to use `offset` and `limit` for additional pages.

6. **Error handling**: When a query fails, explain the reason and suggest adjustments (e.g., verify the image URL is publicly accessible, check country codes, adjust date formats).
## User Expression & Scenario Quick Reference
