Brazil – Grace Periods under the Industrial Property Law (Law No. 9,279/96)
| Modality | Grace Period | Legal Basis | Triggering Event | Consequences of Missing the Deadline |
| Patent of Invention | 12 months | Art. 12, LPI | Disclosure made by the inventor or by third parties who obtained the information directly or indirectly from the inventor. | The disclosure becomes prior art; novelty is destroyed; application is rejected. |
| Utility Model | 12 months | Art. 12, LPI | Same rule as patents of invention. | Same consequence: loss of novelty and rejection. |
| Industrial Design | 180 days | Art. 96, §3, LPI | Disclosure made by the creator or third parties who obtained the information directly or indirectly from the creator. | The disclosure becomes prior art; loss of novelty; registration is denied. |
Key Notes for Clients
- Evidence is critical: To benefit from the grace period, applicants must be able to prove the date and source of disclosure (e.g., invoices, catalogues, exhibition records).
- Hague System: For industrial designs filed via the Hague System designating Brazil, the grace period still applies, provided the filing/priority date falls within the 180-day window.
- Risk factor: Reliance on the grace period can be challenged by third parties in administrative or judicial proceedings. Filing before disclosure remains the best practice.
