This skill guides you on how to search for similar utility (invention) patents based on a product's title, description, and target selling region. It helps cross-border e-commerce sellers identify potential patent infringement risks before listing products.
Utility patent (also called invention patent) protects new and useful inventions or functional improvements. Unlike design patents that protect appearance, utility patents protect how a product works, its structure, or its composition. Infringing on a utility patent can lead to product removal, lawsuits, or TRO orders.
Similarity score: Each returned patent includes a similarity field (0 to 1). A higher value means the patent is more closely related to the queried product. Patents with high similarity scores deserve careful review.
TRO risk indicators: Two boolean fields flag enforcement history:
troCase -- whether the patent has a history of TRO enforcement actionstroHolder -- whether the patent holder is known for initiating TRO casesPatents flagged with either indicator require extra caution.
Patent validity: The patentValidity field shows whether a patent is Active or Invalid. Only active patents pose infringement risk.
| Parameter | Type | Required | Description |
|---|---|---|---|
| productTitle | string | Yes | Product title (max 1000 characters) |
| productDescription | string | Yes | Product description (max 1000 characters) |
| region | string | Yes | Target selling country/region code, comma-separated for multiple. Currently supports: US. Default: US |
| topNumber | integer | Yes | Number of patent results to return. Range: 10--200. Default: 100 |
US is supported. Always set to US unless the user specifies otherwise.POST /ruiguan/utilityPatentDetection (see references/api.md for full parameters/response/error codes)python scripts/utility_patent_detector.py '<JSON parameters>' [--inline]Output strategy (default script behavior):

1. Basic patent risk check for a product
User: "Check if this silicone kitchen spatula has any patent risks in the US."
Build the request with a descriptive product title and description, region set to US, and a reasonable topNumber.
2. Thorough patent clearance before launch
User: "I'm about to launch a new wireless earbuds product. Do a comprehensive patent check."
Use topNumber=200 for maximum coverage. Include detailed product description covering Bluetooth version, charging case design, noise cancellation features, etc.
3. Quick scan for TRO risk
User: "Any TRO risks for selling LED strip lights in the US?"
After retrieving results, filter and highlight patents where troCase or troHolder is true.
4. Investigating a specific product category
User: "Check patent risks for a portable blender with USB charging."
Provide both the product title and a detailed description emphasizing the functional aspects (motor type, blade design, charging mechanism, capacity).
troCase=true or troHolder=true, display a prominent warning about elevated enforcement risk.title) and Chinese title (titleCn) to aid understanding.Applicable -- Patent-related queries for product risk assessment:
| User Says | Scenario |
|---|---|
| "Check patent risk for my product" | Basic patent detection |
| "Any utility/invention patent issues" | Utility patent search |
| "Is this product safe to sell (patent-wise)" | Patent clearance check |
| "TRO risk for this product" | TRO enforcement risk |
| "Similar patents for this product" | Patent similarity search |
| "Patent infringement check" | Pre-launch risk assessment |
| "Will I get sued for selling this" | Patent risk evaluation |
