Zhihuiya Patent PDF Downloader

This skill guides you on how to retrieve patent PDF full-text download links from the Zhihuiya patent database, supporting lookup by patent ID or publication number.

Core Concepts

The Zhihuiya Patent PDF service provides direct download links to the full-text PDF documents of patents worldwide. You can query by patent ID or publication number (also called public announcement number), and retrieve up to 100 patents in a single request.

Lookup priority: When both patentId and patentNumber are supplied, the service uses patentId first. This is important to remember when both identifiers are available.

Family substitution: If a patent's own PDF is unavailable, the service can optionally return the PDF of a related family patent instead.

Parameter Guide

How to Choose the Right Identifier

• Patent ID (patentId): An internal numeric identifier within the Zhihuiya system. Use this when the user provides Zhihuiya-specific IDs.
• Publication Number (patentNumber): The public-facing patent number (e.g., US20230012345A1, CN115000000A). Use this when the user provides standard patent numbers.

Response Fields

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_pdf_data.py directly to run queries.

Usage Examples

1. Single Patent by Publication Number

Retrieve the PDF for patent publication number US20230012345A1.

Parameters: {"patentNumber": "US20230012345A1"}

2. Multiple Patents by Publication Number

Download PDFs for CN115000000A, CN115000001A, and CN115000002A.

Parameters: {"patentNumber": "CN115000000A,CN115000001A,CN115000002A"}

3. Single Patent by Patent ID

Get the full-text PDF for patent ID 12345678.

Parameters: {"patentId": "12345678"}

4. With Family Substitution Enabled

Download the PDF for EP4000000A1. If it is unavailable, use a family patent PDF instead.

Parameters: {"patentNumber": "EP4000000A1", "replaceByRelated": "1"}

5. Batch Download by Patent IDs

Retrieve PDFs for patent IDs 11111111, 22222222, 33333333.

Parameters: {"patentId": "11111111,22222222,33333333"}

Display Rules

1. Present download links clearly: For each patent, show the publication number and its PDF download link in a clean table or list format.
2. Highlight substitutions: If a PDF was provided via family patent substitution, explicitly note this and show the pnRelated value so the user knows which family patent was used.
3. Batch results: When multiple patents are returned, present them in a table with columns: Publication Number, Patent ID, PDF Link, and Substitution Note (if applicable).
4. Error handling: When a query fails or returns no results, explain the reason and suggest the user verify the patent ID or publication number. If replaceByRelated was not enabled, suggest enabling it as an alternative.
5. No PDF available: If a patent entry is returned without a pdfPath, inform the user that the PDF is not available and suggest enabling family substitution.

Important Limitations

• Batch limit: A maximum of 100 patents per request.
• Identifier requirement: At least one of patentId or patentNumber must be provided; the request will fail if both are empty.
• Priority rule: When both identifiers are provided, patentId takes precedence over patentNumber.
• PDF availability: Not all patents have PDFs available. Use the replaceByRelated option to fall back to family patents.
