This skill guides you on how to retrieve abstract images (drawings) from the Eureka patent data platform, helping users quickly obtain the illustrative figures associated with specific patents.
Core Concepts
Abstract images (abstract drawings) are the representative figures attached to a patent document's abstract section. They provide a quick visual overview of the invention. This tool queries the Eureka patent platform and returns download paths for these images.
Lookup logic: You must provide at least one of two identifiers -- a patent ID or a publication number. If both are provided, patent ID takes priority. You can query up to 100 patents in a single request by separating values with commas.
Parameter Guide
| Parameter | API Name | Required | Description | Example |
|---|---|---|---|---|
| Patent ID | patentId | Conditionally (one of the two must be provided) | Internal patent identifier; multiple values separated by commas, max 100 | 5e6f7a8b9c |
| Publication Number | patentNumber | Conditionally (one of the two must be provided) | Patent publication/announcement number; multiple values separated by commas, max 100 | CN115059423A, US11234567B2 |
- At least one of
patentIdorpatentNumbermust be supplied. - If both are supplied,
patentIdtakes precedence. - Multiple values are separated by commas (English commas), with an upper limit of 100.
Response Fields
| Field | API Name | Description |
|---|---|---|
| Patent ID | patentId | The internal patent identifier |
| Publication Number | pn | The publication/announcement number |
| Abstract Drawing Path | abstractDrawingPath | URL path to the abstract image file |
| Total | total | Total number of records returned |
| Cost Token | costToken | Tokens consumed by the query |
How to Call
- API Endpoint：
POST /tool-eureka/abstractImage(For full parameters/responses/error codes, seereferences/api.md） - Python Script：
python scripts/eureka_abstract_image.py '<JSON 参数>' [--inline] - Cost Constraints: This tool consumes credits; by default, the same parameter combination in the same session is called only once, and the script has a 24h local cache. On failure/empty results, do not automatically switch keywords, turn pages, or change zip codes to probe continuously; if you need to continue searching, first explain to the user that additional consumption will be incurred.
Output Strategy (Default Script Behavior)：
- Alwayswrite the complete response to
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-eureka-abstract-image-<timestamp>.json（<cwd>is the working directory when the script is executed, which in Claude Code is the current project directory;<session>is taken from the environment variableSESSION_ID, automatically aggregated according to the user's task;writing to /tmp is prohibited, and if the current directory is not writable, report an error) - Response body ≤ 8 KB: after writing to disk, print the complete JSON to stdout
- Response body > 8 KB: after writing to disk, stdout outputs only a summary (top-level fields, common counts such as
total/costToken, length of the largest list field + first 3 samples) - Add
--inlineto force full printing to stdout (also written to disk)
Data Reading Suggestions: First look at the summary to determine whether it is sufficient; when specific fields are needed, prefer using jqorConvertFrom-Json to extract on demand from the saved json file, avoiding bringing the entire JSON into context.
Resolve Authentication and Credit Issues
When the following abnormal situations occur, take the following measures to handle them:
Abnormal Situation
- API Key not configured: The environment variable is not configured with
LINKFOX_AGENT_API_KEY, andLINKFOXAGENT_API_KEY。 - Response 401 or 402 status code
- Response indicates insufficient credits or balance: The message contains "insufficient credit balance/insufficient billing/insufficient balance/quota exceeded/insufficient balance/package expired/recharge required/please recharge", or content with a similar meaning.
Measures
- Prefer using onboarding.md within the skill to guide problem resolution.
- If the onboarding.md file cannot be found, load the /linkfox-onboarding skill and handle it according to its guidance. If not installed, please install it first:
- Fallback measure: Only when the previous two measures cannot work after all efforts, prompt the user to obtain an API Key according to the https://skill.linkfox.com/linkfoxskills/guide.htm guidance, or go to https://os.linkfox.com/ to add credits.
Usage Examples
1. Single patent lookup by publication number
Retrieve the abstract image for patent CN115059423A.
2. Multiple patents lookup by publication number
Get abstract drawings for patents US11234567B2, EP3456789A1, and CN115059423A.
3. Lookup by patent ID
Fetch the abstract image for patent ID 5e6f7a8b9c.
4. Batch lookup with mixed identifiers
I have the following patent IDs: abc123, def456. Please get their abstract images.
Display Rules
- Show the image: When the response includes an
abstractDrawingPath, display the image directly using Markdown image syntax so the user can see the drawing inline. - Patent identification: Always show the publication number (
pn) alongside each image so the user knows which patent each drawing belongs to. - Missing images: If a patent has no abstract drawing (empty
abstractDrawingPath), explicitly inform the user that no abstract image is available for that patent. - Batch results: When multiple patents are queried, present results in a clear, organized list or table format.
- Error handling: When a query fails, explain the reason based on the response and suggest the user verify their patent IDs or publication numbers.
Important Limitations
- Up to 100 patents per request: The maximum number of patent IDs or publication numbers in a single call is 100.
- At least one identifier required: Either
patentIdorpatentNumbermust be provided; the request will fail if both are empty. - Patent ID priority: When both
patentIdandpatentNumberare provided, the system usespatentIdand ignorespatentNumber. - Data coverage: Results depend on the Eureka patent platform's database coverage; some very recent filings may not yet be reflected.
User Expression & Scenario Quick Reference
Applicable -- Patent abstract image retrieval:
| User Says | Scenario |
|---|---|
| "Show me the abstract image for patent XX" | Single patent image lookup |
| "Get the drawings for these patents" | Batch patent image lookup |
| "What does the patent figure look like" | Abstract drawing retrieval |
| "Retrieve patent illustrations for XX" | Image download path retrieval |
| "I need the abstract drawing for publication number XX" | Lookup by publication number |
Not applicable -- Needs beyond abstract image retrieval:
- Full patent text or claims analysis
- Patent search by keyword or classification
- Patent legal status or family information
- Patent citation or prior art analysis
- Patent valuation or infringement analysis
Credit Consumption Rules
Billed according to dynamic rules: credits consumed = 81 × max(number of returned items, 1).
Important: The services of this skill are dynamically calculated by multiples and may consume a large number of credits at once. The user must be reminded, and the user decides whether to continue.
