3. Compliance Checking

Uses automated analyzers:

Claims Analysis (35 USC 112(b)):

from python.claims_analyzer import ClaimsAnalyzer
analyzer = ClaimsAnalyzer()
results = analyzer.analyze_claims(claims_text)

Checks:

• Antecedent basis (a/an before said/the)
• Definiteness (no subjective terms)
• Claim dependencies (proper structure)
• Cross-references (valid pointers)

Specification Analysis (35 USC 112(a)):

from python.specification_analyzer import SpecificationAnalyzer
analyzer = SpecificationAnalyzer()
results = analyzer.analyze_specification(claims_text, spec_text)

Checks:

• Written description support
• Enablement sufficiency
• Best mode disclosure
• All claim elements supported

Formalities Check (MPEP 608):

from python.formalities_checker import FormalitiesChecker
checker = FormalitiesChecker()
results = checker.check_formalities(title, abstract, spec, has_drawings)

Checks:

• Abstract: 50-150 words
• Title: < 500 characters
• Required sections present
• Drawing references valid

4. Claim Strategy

Prior Art Driven:

1. Review prior art from search
2. Identify distinguishing features
3. Claim novel aspects broadly
4. Add dependent claims for specifics

Claim Set Structure:

• Independent Claim 1: Broad system claim
• Claims 2-7: System dependent claims
• Independent Claim 8: Broad method claim
• Claims 9-15: Method dependent claims
• Independent Claim 16: Alternative embodiment
• Claims 17-20: Alternative dependent claims

Coverage Strategy:

• Multiple independent claims (different angles)
• Layered dependent claims (broad to narrow)
• Fall-back positions (if independent rejected)
• Alternative embodiments (design-arounds)

3. Draft Dependent Claims:

   • Add 10-20 dependent claims
   • Cover specific implementations
   • Include preferred features
   • Create fall-back positions

4. Analyze Claims:
