Preparing for the European Unitary Patent: Transitional Translation Requirements at the EPO
As the sunrise period and transitional measures begin in January 2023 ahead of the Unitary Patent system’s entry into force, patent applicants must navigate mandatory full-text human translation rules under Regulation (EU) No 1260/2012.
Transitional Measures Activated on January 1, 2023
On January 1, 2023, the European Patent Office (EPO) activated its transitional measures allowing applicants to file early requests for unitary effect and delay the grant of a European patent ahead of the Unitary Patent system’s full launch. Under Regulation (EU) No 1260/2012 establishing the translation arrangements for the Unitary Patent, a transitional period of at least six years (and up to twelve years) mandates that patent proprietors submit one full, high-precision human translation of the complete patent specification.
Language Pair Rules and Strict Exclusion of Pure Machine Translation
Specifically, if the language of proceedings before the EPO is French or German, the proprietor must provide a full translation of the European patent specification into English. Conversely, if the language of proceedings is English, the applicant must submit a full translation into any other official language of an EU Member State. Crucially, the regulation explicitly stipulates that during the transitional period, these statutory translations must be carried out by human patent translators and cannot be produced purely by automated machine translation, ensuring legal certainty in potential litigation before the Unified Patent Court.
Executive Takeaways for Global Enterprises
- Key Insight: EPO transitional measures starting January 1, 2023 allow applicants to file early requests for Unitary Patent protection.
- Key Insight: Regulation (EU) No 1260/2012 requires a full human translation into English (if granted in FR/DE) or into any EU official language (if granted in EN).
- Key Insight: Pure machine translation is legally prohibited for Unitary Patent filings during the transitional period.
