N-Spec examines every aspect of your patent application for common issues that lead to objections and rejections
Automatically checks all claim elements for proper antecedent basis. Identifies missing antecedents and suggests closest matches to help you quickly diagnose and fix issues.
Quantifies the degree of descriptive support for each claim element in the specification. Helps identify potentially weak claim language before filing.
Reviews all figure references for naming and numbering consistency between the specification and drawings. Catches missing or mismatched figure references.
Automatically generates a complete parts list showing all reference numerals and their associated part names. Identifies inconsistent naming across the specification.
Scans for common "patent profanities"—words and phrases that examiners flag or that weaken your application. Helps maintain professional, precise language.
Visualizes claim dependency structure and validates proper claim formatting. Ensures claims comply with USPTO requirements and identifies potential dependency issues.
Verifies that title and abstract conform to USPTO requirements for length and format. Flags potential formality issues before filing.
Provides an overall quality score based on all checks performed. Track quality metrics across applications and communicate standards with your team.
