Ruiguan Text Trademark Detection

This skill guides you on how to perform text-based trademark detection against product titles and other product text, helping e-commerce sellers identify potential trademark infringement risks before publishing listings.

Core Concepts

Text Trademark Detection scans product text (titles, descriptions, bullet points) against registered trademark databases across 15 countries/regions. It returns matched trademarks along with risk scores, registration details, and holder information so sellers can avoid intellectual property violations.

Risk score logic: The highestModeScore field ranges from 0 to 5 -- a higher value indicates greater infringement risk. The textTrademarkRadar field classifies overall product risk into three levels: 0 (low risk), 1 (needs manual review), 2 (high risk).

Blacklist and whitelist: The response may include blacklistTrademarks (known dangerous trademarks to always avoid) and whitelistTrademarks (safe trademarks that can be ignored). Always surface blacklist matches prominently to the user.

How to Call

• API Endpoint: POST /ruiguan/textTrademarkDetection (see references/api.md for full parameters/response/error codes)
• Python Script: python scripts/text_trademark_detection.py '<JSON parameters>' [--inline]
• Cost constraint: This tool consumes credits; the same parameter combination in the same session is called only once by default, with 24h local caching in the script. On failure/empty results, do not automatically retry with different keywords, pagination, or filter changes; inform the user before making additional queries.

Output strategy (default script behavior):

• Always write the full response to <cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-ruiguan-text-trademark-detection-<timestamp>.json (<cwd> is the working directory at script execution time, i.e., the current project directory in Claude Code; <session> is taken from the SESSION_ID environment variable, auto-grouped by user task; do not write to /tmp, error if the current directory is not writable)
• Response body <= 8 KB: print the full JSON to stdout after writing to disk
• Response body > 8 KB: stdout only outputs a summary (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)

Data reading tip: Check the summary first to see if sufficient; for specific fields, prefer using jq or ConvertFrom-Json to extract from the saved JSON file on demand, avoiding loading the entire JSON into context.

How to Build Requests

Principles

1. Include the full product title: Always pass the complete product title in productTitle -- partial text may miss trademark matches.
2. Choose target regions: Select regions matching the marketplaces where the product will be sold. Use comma-separated codes for multi-region checks.
3. Provide additional text when available: If the user has bullet points, descriptions, or backend keywords, include them in productText for a more thorough scan.
4. Set an appropriate limit: Use the default of 100 for standard checks. Increase up to 500 when scanning titles with many potential matches.

Usage Examples

1. Basic US Trademark Check for a Product Title

productTitle: "Wireless Bluetooth Headphones Noise Cancelling Over Ear"
regions: "US"
limit: 100

2. Multi-Region Check (US + EU + UK)

productTitle: "Portable USB-C Charger Fast Charging Power Bank"
regions: "US,EM,GB"
limit: 100

3. Full Listing Scan with Additional Text

productTitle: "Stainless Steel Vacuum Insulated Water Bottle"
productText: "BPA-free, double-wall insulation, keeps drinks cold 24 hours, fits standard cup holders"
regions: "US,JP"
limit: 200

4. Broad Global Check

productTitle: "LED Ring Light with Tripod Stand for Streaming"
regions: "US,EM,GB,DE,FR,IT,ES,AU,CA,MX,JP,CN"
limit: 500

5. China Domestic Market Check

productTitle: "Bluetooth noise cancelling headphones"
regions: "CN"
limit: 100

Display Rules

1. Risk-first presentation: Always highlight the overall risk level (textTrademarkRadar) at the top of results. Use clear language: "Low Risk", "Needs Manual Review", or "High Risk".
2. Blacklist prominence: If blacklistTrademarks is non-empty, display them first with a clear warning.
3. Table format: Present trademark matches in a table with columns: Trademark Name, Region, Risk Score, Status, Holder, Application Number, Famous, Amazon Brand, Active Holder.
4. Score explanation: Remind users that highestModeScore ranges from 0 (safe) to 5 (highest risk).
5. Whitelist reassurance: If whitelistTrademarks contains entries, note them as safe/exempted trademarks.
6. Error handling: When a request fails, explain the issue and suggest the user check their product title or adjust regions.
7. No legal advice: Always remind users that results are for reference only and do not constitute legal advice. Recommend consulting an IP attorney for definitive trademark clearance.

Important Limitations

• Result cap: Maximum 500 results per request.
• Character limit: Both productTitle and productText are limited to 1000 characters each.
• Database coverage: Covers 15 countries/regions. Trademarks registered in other jurisdictions may not be detected.
