# Ruiguan Utility Patent Detection

This skill guides you on how to search for similar utility (invention) patents based on a product's title, description, and target selling region. It helps cross-border e-commerce sellers identify potential patent infringement risks before listing products.

## Core Concepts

**Utility patent** (also called invention patent) protects new and useful inventions or functional improvements. Unlike design patents that protect appearance, utility patents protect how a product works, its structure, or its composition. Infringing on a utility patent can lead to product removal, lawsuits, or TRO orders.

**Similarity score**: Each returned patent includes a `similarity` field (0 to 1). A higher value means the patent is more closely related to the queried product. Patents with high similarity scores deserve careful review.

**TRO risk indicators**: Two boolean fields flag enforcement history:
- `troCase` -- whether the patent has a history of TRO enforcement actions
- `troHolder` -- whether the patent holder is known for initiating TRO cases

Patents flagged with either indicator require extra caution.

**Patent validity**: The `patentValidity` field shows whether a patent is `Active` or `Invalid`. Only active patents pose infringement risk.

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| productTitle | string | Yes | Product title (max 1000 characters) |
| productDescription | string | Yes | Product description (max 1000 characters) |
| region | string | Yes | Target selling country/region code, comma-separated for multiple. Currently supports: US. Default: `US` |
| topNumber | integer | Yes | Number of patent results to return. Range: 10--200. Default: `100` |

### Parameter Guidelines

1. **productTitle**: Use the product's actual listing title or a concise descriptive title. Be specific rather than generic -- "portable USB-C fast charger 65W" is better than "charger".
2. **productDescription**: Include key features, materials, mechanisms, and technical attributes. The more detail provided, the more accurate the similarity matching.
3. **region**: Currently only `US` is supported. Always set to `US` unless the user specifies otherwise.
4. **topNumber**: Default is 100. Increase to 200 for a broader search when doing thorough patent clearance. Decrease to 10--20 for a quick preliminary scan.

## 调用方式

- **API 端点**：`POST /ruiguan/utilityPatentDetection`（完整参数/响应/错误码见 `references/api.md`）
- **Python 脚本**：`python scripts/ruiguan_utility_patent_detection.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-ruiguan-utility-patent-detection-<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 references/onboarding.md 引导解决问题：

### 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。

## Usage Examples

**1. Basic patent risk check for a product**

User: "Check if this silicone kitchen spatula has any patent risks in the US."

Build the request with a descriptive product title and description, region set to US, and a reasonable topNumber.

**2. Thorough patent clearance before launch**

User: "I'm about to launch a new wireless earbuds product. Do a comprehensive patent check."

Use topNumber=200 for maximum coverage. Include detailed product description covering Bluetooth version, charging case design, noise cancellation features, etc.

**3. Quick scan for TRO risk**

User: "Any TRO risks for selling LED strip lights in the US?"

After retrieving results, filter and highlight patents where `troCase` or `troHolder` is true.

**4. Investigating a specific product category**

User: "Check patent risks for a portable blender with USB charging."

Provide both the product title and a detailed description emphasizing the functional aspects (motor type, blade design, charging mechanism, capacity).

## Display Rules

1. **Present data in tables**: Show results in a clear, structured table format. Key columns to display: patent title, similarity score, patent validity, application number, publication date, TRO flags, and estimated expiration date.
2. **Sort by relevance**: Display patents sorted by similarity score in descending order (highest similarity first).
3. **Highlight high-risk patents**: Call attention to patents with similarity above 0.7, active validity status, and/or TRO flags.
4. **TRO warnings**: If any returned patents have `troCase=true` or `troHolder=true`, display a prominent warning about elevated enforcement risk.
5. **Validity filtering**: When presenting results, clearly distinguish between Active and Invalid patents. Emphasize that only Active patents require attention.
6. **Volume notice**: When results are large, show the most relevant patents (e.g., top 10--20 by similarity) and summarize the rest.
7. **Error handling**: When a query fails, explain the reason and suggest adjusting the product title or description for better results.
8. **Bilingual titles**: When available, show both the English title (`title`) and Chinese title (`titleCn`) to aid understanding.
9. **No legal advice**: Present patent data factually. Do not provide legal conclusions about infringement -- recommend consulting a patent attorney for definitive assessments.
## Important Limitations

- **Region support**: Currently only US patents are searchable
- **Result cap**: Maximum 200 patents per query
- **Input length**: Both productTitle and productDescription are limited to 1000 characters each
- **Not legal advice**: Results indicate similarity, not confirmed infringement. Professional patent review is always recommended.

## User Expression & Scenario Quick Reference

**Applicable** -- Patent-related queries for product risk assessment:

| User Says | Scenario |
|-----------|----------|
| "Check patent risk for my product" | Basic patent detection |
| "Any utility/invention patent issues" | Utility patent search |
| "Is this product safe to sell (patent-wise)" | Patent clearance check |
| "TRO risk for this product" | TRO enforcement risk |
| "Similar patents for this product" | Patent similarity search |
| "Patent infringement check" | Pre-launch risk assessment |
| "Will I get sued for selling this" | Patent risk evaluation |

**Not applicable** -- Needs beyond utility patent detection:

- Design patent searches (appearance/ornamental design)
- Trademark or brand infringement checks
- Copyright issues
- Product compliance or certification (FCC, CE, etc.)
- General legal advice or contract review
