Can the applicant file voluntary amendments during the processing of a Russian invention patent application?
It goes without saying that an applicant can file amendments to the application in response to an office action. In addition, he or she has an opportunity to file voluntary amendments (irrespective of received office actions) once, at any time after receiving the search report.
From 1 August 2021 an amendment to Article 1378 of the Civil Code gave applicants another opportunity to amend their applications. Applicants can make a voluntary amendment when filing a substantive examination request, which can be filed within three years of the filing date (for PCT applications, the international filing date).
