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
| Parameter | Type | Required | Description |
|---|---|---|---|
| patentId | string | Conditionally | Patent ID(s). At least one of patentId or patentNumber must be provided. Separate multiple values with commas. Max 100 entries. |
| patentNumber | string | Conditionally | Publication/announcement number(s). At least one of patentId or patentNumber must be provided. Separate multiple values with commas. Max 100 entries. |
| replaceByRelated | string | No | Whether to substitute with a family patent PDF when the original is unavailable. 1 = yes, 0 = no. Defaults to no substitution. |
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
| Field | Description |
|---|---|
| total | Number of records returned |
| data | Array of patent objects, each containing download information |
| data[].patentId | The patent ID |
| data[].pn | The publication/announcement number |
| data[].pdfPath | The PDF full-text download URL |
| data[].pnRelated | Publication number of the substitute family patent (only present when family substitution is used) |
| costToken | Tokens consumed by the request |
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
- Present download links clearly: For each patent, show the publication number and its PDF download link in a clean table or list format.
- Highlight substitutions: If a PDF was provided via family patent substitution, explicitly note this and show the
pnRelatedvalue so the user knows which family patent was used. - 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).
- 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
replaceByRelatedwas not enabled, suggest enabling it as an alternative. - 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
patentIdorpatentNumbermust be provided; the request will fail if both are empty. - Priority rule: When both identifiers are provided,
patentIdtakes precedence overpatentNumber. - PDF availability: Not all patents have PDFs available. Use the
replaceByRelatedoption to fall back to family patents.
User Expression & Scenario Quick Reference
Applicable -- Patent PDF document retrieval tasks:
| User Says | Scenario |
|---|---|
| "Download the PDF for patent XX" | Single patent PDF retrieval |
| "Get full-text documents for these patents" | Batch patent PDF download |
| "I need the PDF for publication number XX" | Lookup by publication number |
| "Can I get the patent document even if it's not directly available" | Family substitution scenario |
| "Batch export patent PDFs" | Multi-patent batch download |
Not applicable -- Needs beyond patent PDF retrieval:
- Patent search or discovery (finding patents by keyword, assignee, etc.)
- Patent citation or legal status analysis
- Patent claim interpretation or translation
- Patent portfolio analytics or landscape mapping
