Russia Extends the Patent Filing Window After Public Disclosure

Russia’s State Duma approved a law doubling the deadline for filing a patent application after an invention has been publicly disclosed, extending it from 6 months to 12 months. The change applies to disclosures made in settings such as international exhibitions and is part of amendments to the Russian Civil Code.[2]

This shift is significant for technology inventors and companies because it gives them more time to secure patent protection after showcasing a new technical solution, especially in cross-border innovation and exhibition-driven markets.[2][1]

• What changed: The post-disclosure grace period for patent filing was increased from 6 months to 12 months.

• Why it matters: Inventors presenting technological developments at international venues now have a longer window to preserve patent rights in Russia.

• Broader impact: The move could reduce the risk of accidental loss of patentability for companies operating in global technology markets.
