For Brazilian market sellers, one of the first hurdles is understanding the Brazilian design patent drawing requirements. In Brazil, industrial design is called "Industrial Design Registration" (Registro de Desenho Industrial), and INPI has very specific rules about what views you need to submit.
1. The "6+1" View Standard
INPI requires a minimum of 6 orthogonal views: front view, back view, left side view, right side view, top view, and bottom view. The "+1" refers to one additional perspective or isometric view showing the overall design appearance. All views must be black and white line drawings — no photographs allowed.
2. Common Reasons for Office Actions
- Missing views: not submitting all 6 required orthogonal views.
- Photographs instead of drawings: INPI requires formal line drawings, not product photos.
- Inconsistent dimensions: proportions must be consistent across all views.
3. How to Avoid Correction Actions
Prepare your design views according to INPI's published standards before filing. Use professional industrial design illustrators who are familiar with Brazilian requirements. Include all 7 views (6 orthogonal + 1 perspective) in your initial filing to avoid office actions.
4. Summary
Brazilian design patent applications must follow INPI's "6+1" view standard. Getting the drawings right the first time saves months of office action responses. If you are filing for Brazilian design protection, invest in proper professional drawings before submission.
