get_simple_legal_status

Analyze the simple legal status of patents (e.g., Active, Inactive, Pending) by searching with keywords or IPC codes. Filter results by application, publication dates, or patent authority to assess the proportion of patents currently in effect.

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)"
`public_end_time`	No	Patent publication end year (yyyy format). Filters by publication date.
