--- name: linkfox-zhihuiya-patent-image-search description: 基于智慧芽的专利图片相似度搜索，支持通过图片URL检索外观设计专利和实用新型专利。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专利或排查外观/实用新型专利风险，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 and utility model patents. ## 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. **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. ## Parameter Guide ### Required Parameters | Parameter | Description | Example | |-----------|-------------|---------| | url | The image URL to search against | `https://example.com/product.jpg` | | patentType | Patent type: `D` (design) or `U` (utility model) | `D` | | model | Search model ID (see table above) | `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 | ## API Usage 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. ## 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. Utility model patent search** Check utility model patents with shape/pattern/color matching: ```json { "url": "https://example.com/my-product.jpg", "patentType": "U", "model": 4, "country": "CN", "limit": 20 } ``` **4. 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 } ``` **5. 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 } ``` **6. 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 } ``` **7. 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 **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 **Feedback:** Auto-detect and report feedback via the Feedback API when any of the following apply: 1. The functionality or purpose described in this skill does not match actual behavior 2. The skill's results do not match the user's intent 3. The user expresses dissatisfaction or praise about this skill 4. Anything you believe could be improved Call the feedback API as specified in `references/api.md`.
