# Patent Application Creator Skill

Complete end-to-end patent application creation from invention disclosure to USPTO-ready filing.

## When to Use

Invoke this skill when users ask to:
- Create a complete patent application
- Draft a provisional patent application
- Prepare a utility patent application
- Write patent claims and specification
- Generate a full patent filing package

## What This Skill Does

Orchestrates the complete patent creation workflow:

1. **Prior Art Search** → Identify existing patents
2. **Claims Drafting** → Write independent and dependent claims
3. **Specification Writing** → Create detailed description
4. **Diagram Generation** → Produce technical figures
5. **Abstract Creation** → Write concise summary
6. **Compliance Checking** → Validate USPTO requirements
7. **IDS Preparation** → List prior art for disclosure

## Complete Workflow

### Phase 1: Discovery & Research (15-30 min)

1. **Invention Interview**:
   - Get detailed invention description from user
   - Extract key features and novel aspects
   - Identify problem being solved
   - List all components/steps

2. **Prior Art Search**:
   - Use **Prior Art Search** skill (7-step methodology)
   - Find 10-20 most relevant patents
   - Document key differences
   - Assess patentability

3. **Technology Landscape**:
   - Identify CPC classifications
   - Review competing approaches
   - Find terminology used in field

   - No claim limitations
   - Broad technical description

2. **Title Page Info**:
   - Inventors
   - Assignee
   - Correspondence address
   - Prior applications (if any)

3. **Cross-References**:
   - Related applications
   - Priority claims
   - Provisional references

**Output**: Complete front matter

---

### Phase 6: Compliance & Validation (15-20 min)

1. **Formalities Check**:
   - Use **Patent Claims Analyzer** skill (formalities mode)
   - Abstract length: 50-150 words
   - Title length: < 500 characters
   - Required sections present
   - Drawing references valid

2. **Claims Compliance**:
   - 35 USC 112(b) definiteness
   - Antecedent basis correct
   - No indefinite terms
   - Proper dependencies

3. **Specification Compliance**:
   - 35 USC 112(a) written description
   - Enablement complete
   - Best mode disclosed
   - All claims supported

4. **MPEP Guidance**:
   - Use **MPEP Search** skill
   - Verify format requirements
   - Check section 608 compliance
   - Review any special requirements

**Output**: Compliance report with fixes

---

### Phase 7: Final Assembly (10-15 min)

1. **Document Assembly**:
   - Title page
   - Abstract
   - Drawings (brief description)
   - Specification
   - Claims
   - Abstract (at end)

2. **IDS Preparation**:
   - List all prior art from search
   - Include publication numbers
   - Add filing/grant dates
   - Note relevance

3. **Filing Package**:
   - Specification document
   - Claims document
