## 3. Copyright Assessment

### Elements Reviewed

| Element | Assessment | Status |
|---------|------------|--------|
| Reference ranges | Medical/scientific facts — not subject to copyright | Clear |
| Explanatory text | AI-generated original prose, not copied from any source | Clear |
| UI/UX design | Common web patterns, no proprietary elements copied | Clear |
| Tool names | "Claudius", "Aryash" — original, no trademark conflicts found | Clear |
| "Questions for your GP" feature | Original concept, not found in competitor tools | Clear |
| NHS blue colour scheme (#005eb8) | Not trademarked — widely used across NHS-adjacent services | Clear |

### Content Originality

- All explanatory text was generated by AI (Claude/Anthropic) based on clinical guidance
- No text was copied from NHS, Lab Tests Online UK, or other sources
- Reference ranges derived from NHS/NICE clinical guidelines (factual, not copyrightable)
- GP questions are original, created specifically for this tool

### Closest Equivalent

**Lab Tests Online UK** (labtestsonline.org.uk) is the most similar established resource:
- Run by Royal College of Pathologists, IBMS, and ACB
- Provides detailed test explanations
- However: text-only reference format, no interactive elements, no "questions for GP" feature

**Key differentiators from Lab Tests Online UK:**
1. Interactive slider demonstration (Claudius)
2. "Questions for your GP" for every test
3. Simpler language (reading age ~12 vs medical reference level)
4. Mobile-first design
5. Distinct "learning" vs "results" tool separation

| "Claudius" | No conflicts found in health/medical sector |
| "Aryash" | Original name, no conflicts found |
| "Aryash Health" | Original brand name |
