Zhihuiya Patent Fulltext Image

This skill guides you on how to retrieve fulltext images (drawings, figures, diagrams) from patent documents using the Zhihuiya patent data service, helping users access and analyze visual content within patents.

Core Concepts

Patent fulltext images are the figures, drawings, and diagrams embedded in patent documents. They are essential for understanding the technical details of an invention. This tool queries the Zhihuiya patent database and returns image metadata including download paths and image types for a given patent.

Lookup methods: You can look up images by either patent ID (an internal identifier) or publication number (the publicly visible patent number such as US20230012345A1 or CN115000000A). At least one of these must be provided.

Parameter Guide

Parameter	API Name	Required	Description	Example
Patent ID	patentId	No*	Internal patent identifier	8a7b6c5d-...
Publication Number	patentNumber	No*	Public patent publication/grant number	US20230012345A1
Limit	limit	No	Maximum number of images to return (max 100, default 100)	50
Offset	offset	No	Pagination offset for image results	0

*At least one of patentId or patentNumber must be provided.

Response Fields

Field	Description
total	Total number of image records available
data	Array of image entries
data[].patentId	Patent identifier
data[].pn	Publication/grant number
data[].fulltextImagePath	URL path to download the image
data[].imageType	Type/category of the image
columns	Column rendering metadata
costToken	Token cost of the request
type	Rendering style hint

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_fulltext_image.py directly to run queries.

Usage Examples

1. Get all images for a patent by publication number

Retrieve fulltext images for patent US20230012345A1.

Parameters: {"patentNumber": "US20230012345A1"}

2. Get images for a patent by patent ID

Fetch the drawings for patent ID abc123def456.

Parameters: {"patentId": "abc123def456"}

3. Paginated retrieval of images

Get the first 20 images for patent CN115000000A.

Parameters: {"patentNumber": "CN115000000A", "limit": "20", "offset": "0"}

4. Get the next page of images

Get images 21-40 for patent CN115000000A.

Parameters: {"patentNumber": "CN115000000A", "limit": "20", "offset": "20"}

Display Rules

1. Present data clearly: Show image results in a structured table with image type, download path, and patent number
2. Image links: Always present fulltextImagePath values as clickable links so users can view or download images directly
3. Pagination notice: When total exceeds the number of returned results, inform the user that more images are available and offer to fetch the next page
4. Error handling: When a query fails, explain the reason and suggest verifying the patent ID or publication number
5. No fabrication: Never invent patent IDs, publication numbers, or image URLs -- only display data returned by the API
6. Total count: Always mention the total number of images available for the patent

Important Limitations

• Image limit: Each request returns a maximum of 100 images
• Identifier required: At least one of patentId or patentNumber must be supplied
• All parameters are strings: Even numeric values like limit and offset must be passed as strings

User Expression & Scenario Quick Reference

Applicable -- Requests involving patent visual content:

User Says	Scenario
"Show me the drawings for patent XX"	Fulltext image retrieval
"Get the figures from this patent"	Fulltext image retrieval
"Download patent images for XX"	Fulltext image retrieval
"What diagrams does patent XX contain"	Fulltext image listing
"How many figures are in patent XX"	Image count query
"Show me the technical drawings"	Fulltext image retrieval

Not applicable -- Needs beyond patent fulltext images:

• Patent text/abstract/claims search
• Patent family or citation analysis
• Patent legal status queries
• Patent assignee or inventor search
• General image search unrelated to patents
