基于智慧芽的专利图片相似度搜索，支持通过图片URL检索外观设计专利。当用户提到专利图片搜索、外观设计专利侵权检查、外观专利搜索、视觉专利查询、以图搜专利、专利相似度检测、专利图片匹配、洛迦诺分类搜索、检查产品设计是否侵犯已有专利、patent image search, design patent search, patent reverse image search, design patent lookup, PatSnap, patent similarity时触发此技能。即使用户未明确提及"智慧芽"或"专利图片"，只要其需求涉及通过图片查找相似外观专利或排查外观专利风险，也应触发此技能

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. Parameter Guide Required Parameters Parameter Description Example url The image URL to search against https://example.com/product.jpg patentType Patent type, fixed to D (design) by this skill D model Search model ID: 1 (recommended) or 2 1 Common Optional Parameters Parameter Description Default country Patent authority country codes, comma separated (e.g., CN,US,JP ) All countries loc Locarno classification codes, connectable with AND/OR/NOT None legalStatus Legal status codes, comma separated None simpleLegalStatus Simple legal status: 0 (expired), 1 (active), 2 (pending) None assignees Applicant / patent holder name None applyStartTime Application start date ( yyyyMMdd ) None applyEndTime Application end date ( yyyyMMdd ) None publicStartTime Publication start date ( yyyyMMdd ) None publicEndTime Publication end date ( yyyyMMdd ) None limit Number of results to return (1 100) 10 offset Pagination offset (0 1000) 0 field Sort field: SCORE , APD , PBD , ISD SCORE order Sort order: desc or asc (for APD/PBD/ISD) desc lang Title language preference: original , cn , en original preFilter Enable country/LOC pre filtering: 1 (on) / 0 (off) 1 stemming Enable stemming: 1 (on) / 0 (off) 0 mainField Search within title, abstract, claims, description, publication number, application number, applicant, inventor, IPC/UPC/LOC None includeMachineTranslation Include machine translated data in search None scoreExpansion Enable score expansion None isHttps Return HTTPS image URLs: 1 (yes) / 0 (no) 0 returnImgId Return image IDs in results false Commonly Used Country Codes Code Country/Region CN China US United States JP Japan KR South Korea EP European Patent Office WO WIPO DE Germany GB United Kingdom FR France AU Australia 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 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。 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: 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: 2. Design patent search limited to specific countries Search only in China and the United States: 3. Search with Locarno classification filter Narrow results to a specific product category (e.g., LOC 07 01 for tableware): 4. Search only active patents within a date range Find active design patents filed after 2020: 5. Search by specific assignee Find patents held by a particular company: 6. Get results with Chinese translated titles 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 Applicable Image based patent similarity searches: User Says Scenario "Check if my product design infringes any patents" Design patent infringement check "Search for similar design patents" Design patent similarity search "Find patents that look like this image" Visual patent lookup "Are there any patents similar to my product appearance" Appearance risk assessment "Utility model patent search by image" Utility model search "Check patent risks for this product in China and US" Multi country patent check "Find active design patents in this category" Filtered patent search "Who holds patents similar to this design" Competitor patent discovery Not applicable Needs beyond patent image search: Text based patent search (keyword/abstract/claim search) Patent legal status monitoring or annuity management Patent valuation or licensing negotiation Freedom to operate (FTO) legal opinions Patent family or citation analysis 积分消耗规则消耗 81 积分。用户会因积分消耗而支付费用。请充分评估：当需要高频调用本技能，或用户对积分消耗量预期不足时，务必提醒用户，由用户决定是否继续。 Feedback: Auto detect and report feedback via the Feedback API when any of the following apply: 1.
