Russia Extends Patent Filing Window After Public Disclosure of an Invention

Russia has approved a change that gives inventors 12 months instead of six to file a patent application after publicly disclosing an invention, including at international exhibitions. The move aligns the filing window with the Paris Convention standard and is intended to reduce the risk of losing patent rights after public presentation.

• The law was approved by the Federation Council on 16 July 2026, placing the change close to the publication date and within the target month.
• The rule applies to inventions disclosed publicly, which is especially relevant for technology inventions shown at international forums, trade fairs, and scientific exhibitions.
• Supporters frame the reform as a practical measure for researchers and developers who need more time to complete patent paperwork after demonstrating new technical solutions.
• The change also strengthens Russia’s patent system in response to concerns about patent trolling and the protection of legitimate inventors.
