get_wheel_of_innovation
Analyze hierarchical keyword and IPC relationships in patent data to uncover common terms and their associations. Supports filtering by date, authority, and language for targeted technology insights.
Instructions
Provides a two-tiered hierarchical view of keywords/phrases in a technology space. Identify common terms and their associations. Based on the most recent 5,000 publications. Either keywords or IPC classification must be specified.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| apply_end_time | No | Patent application end year (yyyy format). Filters by application filing date. | |
| apply_start_time | No | Patent application start year (yyyy format). Filters by application filing date. | |
| authority | No | Patent authority code (e.g., CN, US, EP, JP). Filters by patent office. Use OR for multiple, e.g., "US OR EP". | |
| ipc | No | Patent IPC classification code. Used to specify a particular technology field. | |
| keywords | No | Keywords to search within patent title and abstract/summary. Supports AND, OR, NOT logic. Example: "mobile phone AND (screen OR battery)" | |
| lang | No | Language setting. Default is "en" (English). Choose "cn" (Chinese) or "en". | |
| public_end_time | No | Patent publication end year (yyyy format). Filters by publication date. | |
| public_start_time | No | Patent publication start year (yyyy format). Filters by publication date. |
