Patent Claims Analyzer

Required Data

This skill uses the automated claims analyzer from: Location: ${CLAUDE_PLUGIN_ROOT}/python\claims_analyzer.py

How to Use

When this skill is invoked:

1. Load the claims analyzer:

   import sys
   sys.path.insert(0, os.path.join(os.environ.get('CLAUDE_PLUGIN_ROOT', '.'), 'python'))
   from python.claims_analyzer import ClaimsAnalyzer
   
   analyzer = ClaimsAnalyzer()
   

2. Analyze claims:

   claims_text = """
   1. A system comprising:
       a processor;
       a memory; and
       said processor configured to...
   """
   
   results = analyzer.analyze_claims(claims_text)
   

3. Present analysis:

   • Show compliance score (0-100)
   • List issues by severity (critical, important, minor)
   • Provide MPEP citations for each issue
   • Suggest specific fixes

    ]
}

Common Issues Detected

1. Antecedent Basis Errors:

   • Using "said/the" before "a/an" introduction
   • Terms appearing in dependent claims not in parent
   • Missing antecedent in claim body

2. Definiteness Issues:

   • Subjective terms: "substantially", "about", "approximately"
   • Relative terms: "large", "small", "thin"
   • Ambiguous language: "and/or", "optionally"

3. Structure Issues:

   • Means-plus-function without adequate structure
   • Improper claim dependencies
   • Missing preamble or transition
