Try in Sandbox

Intelligently parse claim text to automatically identify independent claims, dependent claims and their structural information. Provides detailed claim type analysis, paragraph structure division, technical feature extraction and other functions to help users deeply understand the composition and hierarchical relationships of patent claims.

Features: 1. Automatically identify independent and dependent claims 2. Analyze claim technical types (method, device, composition, etc.) 3. Divide claim paragraph structure (concept, transitional, refinement parts) 4. Extract technical features and limitations of claims 5. Supports parsing of Chinese and English claim texts
