Zhihuiya Patent Image 搜索

This 技能 图形界面des you on how to perform image-based patent similarity 搜索es using the Zhihuiya patent database, helping users identify potentially similar de签名 patents and 实用工具 模型 patents.

Core Concepts

Patent Image 搜索 uses visual AI 模型s to compare a given product or de签名 image agAInst a global patent image database. It returns a ranked 列出 of similar patents, enabling users to evaluate infringement risks or conduct prior-art re搜索.

Two patent types are supported:

Type Code Description De签名 Patent D 保护s the ornamental 应用earance of a product (default) 实用工具 模型 Patent U 保护s the functional shape/structure of a product

搜索 模型s vary by patent type:

模型 ID Patent Type Strategy Recommendation 1 De签名 (D) Intelligent Association Recommended for de签名 patents 2 De签名 (D) 搜索 This Image Exact visual match 3 实用工具 模型 (U) Match Shape Shape-only comparison 4 实用工具 模型 (U) Match Shape/Pattern/Color Recommended for 实用工具 模型 patents

Scoring 记录ic: A higher score value means greater visual similarity. When presenting 结果s, 排序 by score in descending order (highest similarity first) so users can prioritize the most relevant patents for review.

Usage Examples

• Basic de签名 patent 搜索 (recommended 启动ing point) 搜索 for de签名 patents similar to a product image across all countries:

{ "url": "https://example.com/my-product.jpg", "patentType": "D", "模型": 1, "limit": 20 }

• De签名 patent 搜索 limited to specific countries 搜索 only in China and the United 状态s:

{ "url": "https://example.com/my-product.jpg", "patentType": "D", "模型": 1, "country": "CN,US", "limit": 20 }

• 实用工具 模型 patent 搜索 检查 实用工具 模型 patents with shape/pattern/color matching:

{ "url": "https://example.com/my-product.jpg", "patentType": "U", "模型": 4, "country": "CN", "limit": 20 }

• 搜索 with Locarno classification 过滤器 Narrow 结果s to a specific product category (e.g., LOC 07-01 for tableware):

{ "url": "https://example.com/my-product.jpg", "patentType": "D", "模型": 1, "loc": "07-01", "pre过滤器": 1, "limit": 20 }

• 搜索 only active patents within a date range Find active de签名 patents filed after 2020:

{ "url": "https://example.com/my-product.jpg", "patentType": "D", "模型": 1, "simpleLegal状态": "1", "应用ly启动Time": "20200101", "limit": 30 }

• 搜索 by specific as签名ee Find patents held by a particular company:

{ "url": "https://example.com/my-product.jpg", "patentType": "D", "模型": 1, "as签名ees": "应用le Inc.", "limit": 20 }

• 获取 结果s with Chinese-translated titles

{ "url": "https://example.com/my-product.jpg", "patentType": "D", "模型": 1, "lang": "cn", "limit": 20 }

Display Rules

排序 by score: Always 排序 结果s by score in descending order (highest similarity first) to help users quickly identify the most relevant infringement risks.
