These can be found in Art. 54 of the Patent Law of 2007. Pursuant to Art. 54(1) PL, any person may apply for a compulsory licence if a patented invention has not been used in Latvia or has been used to an insufficient degree within four years from the date of application or three years from the date on which the grant of a patent was published. Pursuant to Art. 16(1) PL, importation of a patented product qualifies as use of that invention. The licence will be refused if the patent proprietor proves to the court that there are reasonable grounds why the invention has not been used or has been used to an insufficient degree.
