Zhihuiya Patent Claims (Translated)

This skill guides you on how to query translated patent claims from the Zhihuiya (PatSnap) patent database, enabling users to retrieve claim texts in Chinese, English, or Japanese for a single patent per request.

Core Concepts

Patent claims define the legal scope of protection granted by a patent. This tool retrieves the translated text of patent claims, 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.

Data Fields

Field	API Name	Description	Example
Patent ID	patentId	Internal patent identifier	84a1b2c3-...
Publication Number	pn	Publication (announcement) number of the patent	CN112345678A
Related Publication Number	pnRelated	Publication number of the substitute family patent (only present when family substitution is used)	US20210012345A1
Claims	claims	Translated patent claim text	1. A method for...

Supported Languages

Code	Language
en	English (default)
cn	Chinese
jp	Japanese

Default language is en (English). Use English when the user does not specify a language.

Calling the Tool

• API Endpoint: /zhihuiya/claimDataTranslated (full parameters/responses/error codes in references/api.md)
• Python Script: python scripts/patent_claims_translation.py '<JSON params>' [--inline]
• Cost constraint: This tool consumes credits. Within the same session and same parameter combination, it defaults to a single call with a 24-hour local cache. Do not automatically retry with different keywords, pagination, or parameters on failure/empty results. Inform the user of additional credit consumption before continuing retrieval.

Output strategy (script default behavior):

• Always write the full response to <cwd>/nexscope/<YYYY-MM-DD>/<session>/data/ecommerce-patent-claims-translated-<timestamp>.json (<cwd> is the working directory when the script executes, which in Claude Code is the current project directory; <session> is taken from the SESSION_ID environment variable, automatically grouped by user task; do not write to /tmp; error if the current directory is not writable)
• Response body <= 8 KB: write to disk then print full JSON to stdout
• Response body > 8 KB: write to disk then print only a summary to stdout (top-level fields, common counts like total/costToken, length of the largest list field + first 3 samples)
• Add --inline to force full output to stdout (still writes to disk)

Reading data: Check the summary first to determine if it is sufficient. When specific fields are needed, use jq or ConvertFrom-Json to extract from the saved JSON file as needed, avoiding loading the entire JSON into context.

Authentication & Credits

If you encounter authentication or credit issues:

Error conditions

• API Key not configured: The NEXSCOPE_API_KEY environment variable is not set.
• HTTP 401 or 402 status code
• Insufficient credits/balance: Response message indicates credit balance exhausted, quota exceeded, subscription expired, or recharge required.

Resolution steps

1. Set the NEXSCOPE_API_KEY environment variable with a valid API key.
2. If credits are insufficient, visit https://www.nexscope.ai/pricing?co-from=skillNS to top up your balance.

Parameter Guide

Patent Identification

You must provide at least one of the following:

• patentId -- The internal patent ID. When both patentId and patentNumber are provided, patentId takes precedence. Single patent ID only. Do NOT pass comma-separated multiple IDs.
• patentNumber -- The publication or announcement number. Single publication/announcement number only. Do NOT pass comma-separated multiple numbers.

Optional Parameters

• lang -- Target translation language: en (English, default), cn (Chinese), or jp (Japanese).
• replaceByRelated -- Whether to substitute claims from a family patent when the original claims are unavailable: 1 = yes, 0 = no (default).

Single-patent limit: This endpoint consumes significant credits. To query multiple patents, obtain explicit user consent and make separate calls for each. Only 1 patent per call (patentId and patentNumber do not accept comma-separated multiple values).

Usage Examples

1. Get English claims for a single patent by publication number

patentNumber: "CN112345678A"
lang: "en"

3. Get Japanese claims with family patent fallback

patentNumber: "JP2021123456A"
lang: "jp"
replaceByRelated: 1

4. Query by patent ID

patentId: "84a1b2c3-d4e5-6f78-9abc-def012345678"
lang: "en"

Display Rules

1. Present claims clearly: Show the translated claim text with proper formatting. Results contain a single patent's data per call.
2. 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.
3. Language notice: State the language of the returned claims so the user knows which translation they are viewing.
4. Large results: When the response is large, summarize the count and show a few representative entries, reminding the user of the total.
5. Error handling: When a query fails, explain the reason based on the error response and suggest checking the patent ID or publication number.

Important Limitations

• At least one identifier required: Either patentId or patentNumber must be provided; otherwise the query will fail.
• Single patent per request: Only one patent ID or publication number may be passed per call (no comma-separated batches).
• 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.

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
"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
