Zhihuiya Patent Image Search

智慧芽专利图片搜索

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 and utility model patents.

本技能将指导您如何使用智慧芽专利数据库进行基于图片的专利相似度搜索，帮助用户识别潜在相似的外观设计专利和实用新型专利。

Core Concepts

核心概念

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.

Two patent types are supported:

Type	Code	Description
Design Patent	`D`	Protects the ornamental appearance of a product (default)
Utility Model Patent	`U`	Protects the functional shape/structure of a product

Search models vary by patent type:

Model ID	Patent Type	Strategy	Recommendation
1	Design ( `D` )	Intelligent Association	Recommended for design patents
2	Design ( `D` )	Search This Image	Exact visual match
3	Utility Model ( `U` )	Match Shape	Shape-only comparison
4	Utility Model ( `U` )	Match Shape/Pattern/Color	Recommended for utility model patents

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.

专利图片搜索借助视觉AI模型，将给定的产品或设计图片与全球专利图片数据库进行比对，返回按相似度排序的专利列表，助力用户评估侵权风险或开展现有技术研究。

支持两种专利类型：

类型	代码	描述
外观设计专利	`D`	保护产品的装饰性外观（默认类型）
实用新型专利	`U`	保护产品的功能性形状/结构

搜索模型因专利类型而异：

模型ID	专利类型	策略	推荐场景
1	外观设计（ `D` ）	智能关联	推荐用于外观设计专利搜索
2	外观设计（ `D` ）	原图搜索	精确视觉匹配
3	实用新型（ `U` ）	形状匹配	仅比对形状
4	实用新型（ `U` ）	形状/图案/颜色匹配	推荐用于实用新型专利搜索

评分逻辑：

score

值越高表示视觉相似度越高。展示结果时，需按score降序排列（相似度从高到低），方便用户优先查看最相关的专利。

API Usage

API使用说明

This tool calls the LinkFox tool gateway API. See

references/api.md

for calling conventions, request parameters, and response structure. You can also execute

scripts/zhihuiya_patent_image_search.py

directly to run queries.

本工具调用LinkFox工具网关API。调用规范、请求参数和响应结构详见

references/api.md

。您也可以直接执行

scripts/zhihuiya_patent_image_search.py

来运行查询。

Local Image Upload

本地图片上传

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.

本工具要求图片URL必须可公开访问。若用户提供本地图片文件路径（例如：

C:\Users\...\photo.png

、

/home/.../image.jpg

），您必须先上传图片以获取公开URL。

运行上传脚本：

bash

python scripts/upload_image.py /path/to/local/image.png

脚本将返回一个有效期为24小时的公开URL，可作为图片URL参数使用。
