Samsung and Apple agreed to drop all litigation cases between them in all countries, except for those currently pending in the United States.
That means some 30 lawsuits will be dropped in courts in eight countries, including Korea, Japan, Germany and France.
However the joint statement released Wednesday says the agreement does not cover any cross-licensing arrangements between the two smartphone rivals.
The lawsuits between the world's two biggest smartphone makers began in 2011 when Apple sued Samsung for copying iPhone features.
Samsung responded by countersuing Apple for infringing its wireless-transmission technology.
The patent trials have since spread to courts around the globe.
The mood of rapprochement began in May, when Samsung and Apple agreed to drop lawsuits related to Motorola Mobility.
One month later, they agreed to dismiss their appeals of a patent case at the U.S. International Trade Commission.
This week's agreement leaves just two cases pending in the U.S., both currently in the appeals process.
In May, a jury ordered Samsung to pay Apple some 120 million U.S. dollars in damages, it also ordered Apple to pay some 160-thousand U.S. dollars to Samsung for patent infringements.
In a separate case in a U.S. court in 2012, a jury verdict ordered Samsung to pay Apple 930 million U.S. dollars.
Both cases are currently being appealed.
