get_simple_legal_status
Analyze patent legal status (Active, Inactive, Pending) for a specific technology field using keywords or IPC codes. Filter by application, publication dates, and patent authorities to understand active patent proportions.
Instructions
Provides a breakdown of the simple legal status (e.g., Active, Inactive, Pending) for patents in the technology field. Understand the proportion of patents currently in effect. Note: Search must contain either keywords or IPC. If both are provided, IPC is prioritized.
Input Schema

|---|---|---|---|
| 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)" | |
