The court dismissed all bribery charges related to the export of armoured vehicles to Slovenia citing lack of evidence.
Five people were charged with bribery including former CEO of the company Jorma Wiitakorpi and Heikki Hulkkonen, CEO of a subsidiary.
There was also no evidence that Patria or its subsidiary paid anything to Slovenian officials, soldiers or the people around them or the Slovenian prime minister at the time.
Former Slovenian prime minister Janez Janša was convicted last summer and sentenced to two years in jail by a court in Slovenia in relation to the armoured vehicle deal.
The court ordered the state to pay the defendants legal costs totalling more than a million euros.
