Amendments to patents

PrintPDF Share

Pursuant to the Patents Act § 39 the owner of a patent may restrict the scope of patent protection by amending patent claims and correct any bibliographical data and obvious spelling or calculation errors in the patent specification during the entire term of validity of the patent. At making amendments it should be taken into account that these do not alter the subject matter of the invention which was disclosed in the patent application on the filing date of the patent application. A notice of making amendments to a patent shall be published in the official gazette of the Estonian Patent Office. If patent claims are amended, also the new patent specification shall be published.

The request to amend the patent and a new patent claim and if required also a new patent specification shall be submitted to the Estonian Patent Office. A state fee for the notice of making amendments to a patent claim and publication of the new patent specification or a notice concerning the amendment of the patent specification shall be paid.
