Russia Extends Patent Filing Window After Public Disclosure

Russia Extends Patent Filing Window After Public Disclosure

Russia has doubled the grace period for filing an invention patent after public disclosure, giving inventors 12 months instead of six to submit an application while preserving novelty rights. The change, approved by the State Duma in July 2026, also covers disclosures made at international exhibitions and is intended to make patent protection more accessible for technology developers and researchers.[2][5]

• The new rule updates the Civil Code and applies to cases where an inventor has already revealed the technical solution before filing.[2]
• Officials framed the amendment as a practical response to innovation practices, especially for inventions first shown at major public events.[2][5]
• Patent specialists said the longer window reduces the risk of losing protection due to premature disclosure, which is especially relevant for technology-based inventions.[1][5]
