Your Mission

Draft a complete, filing-ready patent application including:

1. Patent claims (independent and dependent)
2. Detailed specification
3. Abstract
4. Background section
5. Summary section

Process

Step 1: Analyze Input

• Read invention disclosure or description
• Extract key inventive concepts
• Identify technical field
• Understand problem and solution
• Note advantages and embodiments

Step 2: Prior Art Check

• Check if prior art analysis exists in patents/analysis/
• If not, recommend conducting prior art search first
• Review any existing prior art to inform claim scope

Step 3: Draft Claims

Create patents/drafts/[invention-name]-claims.md:

Independent Claims (at least 3):

• System/apparatus claim
• Method claim
• Computer-readable medium claim (if software)

Dependent Claims (5-10 per independent):

• Add specific implementations
• Cover alternative embodiments
• Progress from broad to narrow
• Ensure claim differentiation

Quality Checks:

• Proper antecedent basis (a/an → the)
• Single sentence for independent claims
• Clear, definite language
• Avoid vague terms
• Run: cd tools && python claim-analyzer.py ../patents/drafts/[invention-name]-claims.md

Step 4: Draft Specification

Create patents/drafts/[invention-name]-application.md using template.

Title: 2-7 words, descriptive

Background:

• Technical field identification
• Problem description
• Limitations of existing solutions
• Need for invention

Summary:

• High-level description of invention
• Key features and advantages
• How it solves the problem
• 2-3 paragraphs

Detailed Description:

• Reference numbers assigned systematically (100s, 200s, etc.)
• Main embodiment first
• Alternative embodiments (at least 2)
• Detailed operation explanation
• All claim elements described with support
• Advantages and unexpected results

Ensure:

• Written description support for all claims
• Enablement (person skilled in art can make/use)
• Consistent terminology throughout
• Present tense, active voice
• Technical accuracy

Step 5: Draft Abstract

Create patents/drafts/[invention-name]-abstract.md:

• Single paragraph
• 50-150 words (must be ≤150)
• What invention is + what it does
• No reference numbers
• Present tense
• Run: cd tools && python word-count.py ../patents/drafts/[invention-name]-abstract.md

Step 6: Quality Assurance

Terminology Consistency:

• Create term glossary
• Verify same terms used throughout
• No synonyms for key concepts

Antecedent Basis:

• All claims checked
• Specification checked
• No improper introductions

Completeness:

• All sections present
• All claims supported
• All reference numbers explained
• Proper formatting

Run Tools:

cd tools
python claim-analyzer.py ../patents/drafts/[invention-name]-claims.md
python word-count.py ../patents/drafts/[invention-name]-abstract.md

Recommendations:

• Prior art search (if not done)
• Professional patent attorney review
• Figure preparation needed
• Filing strategy advice

Next Steps:

• Review and refine
• Prepare figures/drawings
• Conduct prior art search (if needed)
• Attorney review before filing

Templates to Use

• templates/applications/utility-patent-template.md
• templates/claims/claims-template.md
• templates/abstracts/abstract-template.md

Rules

Follow all guidelines in CLAUDE.md:

• Patent-specific writing standards
• Proper claim format
• Consistent terminology
• Quality checks before completion
• Professional disclaimer (not legal advice)

Work autonomously but ask for clarification if:

• Invention description is unclear
• Multiple valid approaches exist
• Technical details are missing
• Prior art impacts claim scope significantly

Be thorough, precise, and produce filing-ready documents.
