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.
This skill supports utility model patents only:
TypeCodeDescription
Utility Model Patent
U
Protects the functional shape/structure of a product
Search models for utility model patents:
Model IDStrategyRecommendation
3Match ShapeShape-only comparison
4Match Shape/Pattern/ColorRecommended for utility model patents (default)
Design patents (model 1/2) are not supported by this skill. Use
linkfox-zhihuiya-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.
Patent Image Search 利用视觉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,返回相似专利的排序列表,帮助用户评估侵权风险或开展现有技术研究。
本技能仅支持utility model patent:
类型代码说明
Utility Model Patent
U
保护产品的功能性形状/结构
实用新型专利搜索模型:
模型ID匹配策略推荐说明
3仅匹配形状仅进行形状比对
4匹配形状/图案/色彩实用新型专利推荐使用(默认)
本技能不支持外观设计专利(模型1/2),请使用
linkfox-zhihuiya-patent-image-search
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),以便用户优先查看最相关的专利。

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.
本工具需要可公开访问的图片URL。如果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image URL参数使用。

Display Rules

展示规则

  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
    • IPC/UPC classification information
    • 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).
  1. 按评分排序:始终按
    score
    降序排列结果(相似度从高到低),帮助用户快速识别最相关的侵权风险。
  2. 展示完整细节:总结结果或生成报告时,需为每个专利包含以下所有信息,不得省略或缩写:
    • 申请号(
      apno
    • 中文专利标题(使用
      lang: cn
      参数或提供翻译)
    • 发明人(
      inventor
    • 专利附图(匹配的
      url
      图片)
    • 图片列表中的每一张专利图片
    • 专利摘要
    • 专利说明书
    • IPC/UPC分类信息
    • 若有Radar结果(
      radarResult
      )需包含
    • 专利说明书全文
  3. 法律声明:在结果末尾必须添加友好提示:
    本搜索结果由LinkfoxAgent生成,建议咨询专业专利律师获取法律意见。
  4. 评分说明:提醒用户评分代表视觉相似度——分数越高表示匹配度越高,但不构成侵权的法律判定。
  5. 分页指引:当总结果数超过返回数量时,告知用户匹配专利的总数,并引导其使用
    offset
    limit
    参数获取更多页面结果。
  6. 错误处理:查询失败时,说明原因并建议调整方案(例如:验证图片URL是否可公开访问、检查国家代码、调整日期格式)。
