No substantive examination on inventions is stipulated by the Latvian legislation, a patent is issued on the responsibility of an applicant and may be appealed in court. A patent is issued after payment of the registration and publication fees.

Foreign applicants must be represented before the Office by a registered Latvian patent attorney.
