Temporary protection for published applications for European patents, under which the Republic of Bulgaria (BG) is a specified country is provided on the basis of Art. 18 of the APRUM. The protection is granted retroactively from the publication for granting the patent, in case a European patent is issued and the same is valid on the territory of the Republic of Bulgaria.
The applicant has the right to receive fair compensation from any person who, without his permission, has committed any of the actions under Art. 19, para. 3 of the APRUM for the period from the publication of a received translation of the patent claims under a filed and published patent application until the date of publication for the grant of a European patent in the European Patent Bulletin.
