This skill guides you on how to query translated patent claims from the Eureka patent data platform, enabling users to retrieve claim texts in Chinese, English, or Japanese for one or more patents.
Core Concepts
Patent claims define the legal scope of protection granted by a patent. This tool retrieves the translated text of patent claims from the Eureka platform, supporting three languages: Chinese (cn), English (en), and Japanese (jp). You can look up patents by their internal patent ID or by their publication (announcement) number.
Family patent substitution: When claims are unavailable for a specific patent, the tool can optionally substitute claims from a related family patent. This is controlled by the replaceByRelated parameter.
Parameter Guide
Parameter
Type
Required
Description
patentId
string
At least one of patentId or patentNumber
Internal patent ID. Separate multiple IDs with commas. Up to 100 patents per request.
patentNumber
string
At least one of patentId or patentNumber
Publication (announcement) number. Separate multiple numbers with commas. Up to 100 patents per request.
replaceByRelated
integer
No
Whether to substitute claims from a family patent when unavailable. 1 = yes, 0 = no. Default 0.
lang
string
No
Target translation language. en = English (default), cn = Chinese, jp = Japanese.
Key Rules
At least one identifier is required: You must provide either patentId or patentNumber (or both). If both are supplied, patentId takes priority.
Batch queries: Multiple patents can be queried at once by separating values with commas, up to 100 per request.
Default language is English: When the user does not specify a language, use en.
Family fallback: Set replaceByRelated to only when the user explicitly wants substitute claims from a family patent if the original is missing.

Usage Examples
1. Get English claims for a single patent by publication number
Show me the English claims for patent CN112345678A.
Parameters: patentNumber = "CN112345678A", lang = "en"
2. Get Chinese claims for multiple patents
Get the Chinese translation of claims for US20210012345A1 and EP3456789B1.
Parameters: patentNumber = "US20210012345A1,EP3456789B1", lang = "cn"
3. Get Japanese claims with family patent fallback
Get Japanese claims for JP2021123456A. If unavailable, try a family patent.
Parameters: patentNumber = "JP2021123456A", lang = "jp", replaceByRelated = 1
4. Query by patent ID
Get claims for patent ID 84a1b2c3 in English.
Parameters: patentId = "84a1b2c3", lang = "en"
5. Batch query with fallback enabled
Translate claims for these patents: CN112345678A, US20200012345A1, EP3456789B1. Use family patents if needed.
Parameters: patentNumber = "CN112345678A,US20200012345A1,EP3456789B1", lang = "en", replaceByRelated = 1
Display Rules
Present claims clearly: Show the translated claim text with proper formatting. If multiple patents are returned, separate each patent's claims with its publication number as a heading.
Family substitution notice: When pnRelated is present in the response, clearly inform the user that the claims were sourced from a related family patent and show the substitute publication number.
Language notice: State the language of the returned claims so the user knows which translation they are viewing.
Large results: When multiple patents are returned, summarize the count and show a few representative entries, reminding the user of the total.
Error handling: When a query fails, explain the reason based on the error response and suggest checking the patent ID or publication number.
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/eureka_claim_translated.py directly to run queries.
Important Limitations
At least one identifier required: Either patentId or patentNumber must be provided; otherwise the query will fail.
Batch limit: A maximum of 100 patents per request.
Language support: Only Chinese (cn), English (en), and Japanese (jp) are supported.
Family substitution: Substitute claims are only returned when replaceByRelated is set to 1 and the original claims are unavailable.
No claim analysis: This tool returns raw translated text only; it does not analyze or compare claims.
User Expression & Scenario Quick Reference
Applicable -- Queries related to patent claim text and translation:
User Says
Scenario
"Show me the claims for patent XX"
Single patent claim lookup
"Translate claims to Chinese/Japanese"
Claim translation
"What does patent XX claim?"
Claim content retrieval
"Get claims for these patents: XX, YY"
Batch patent claim lookup
"Claims unavailable, try family patent"
Family patent substitution
"Patent rights scope of XX"
Claim text retrieval
Not applicable -- Needs beyond patent claim translation:
Patent search or discovery (finding patents by keyword)
Patent citation or legal status analysis
Patent abstract or description retrieval
Patent portfolio analytics or statistics
Boundary -- Edge cases:
If the user asks for "patent text" without specifying claims, clarify whether they want claims, abstract, or description.
If the user provides more than 100 patents, split into multiple batches.

Handling Large Responses
To avoid overflowing the agent context, persist the response to disk and extract only the fields you need:
python scripts/response_io.py run --script scripts/eureka_claim_translated.py --out-dir <DIR> '<params>'
python scripts/response_io.py read <file> --fields "<paths>" # or --path "<JMESPath>"
Pick --out-dir outside any git working tree (e.g. /tmp/... on Unix, %TEMP%/... on Windows). Persisted responses may contain PII, pricing, or auth-sensitive data — do not commit them. Files are not auto-deleted; clean up when the task is done.
run writes the full response to a file and emits only a schema preview + file path. read projects specific fields, with --limit/--offset for slicing and --format json|jsonl|csv|table for output.
When to prefer this pattern — apply your judgment based on the response characteristics, e.g.:
High field count per record, or fields you don't need
Batch/paginated results (multiple items per call)
Long-text fields (descriptions, reviews, HTML, time series)
Output reused across later steps rather than consumed immediately
For small, single-use responses, calling the main script directly is fine.
⚠️ The preview is a truncated schema + sample, not the full data. Any field-level decision must read from the persisted file via read.
