The legal consequences of the beginning of the war: 1. Diplomatic and consular relations are severed; 2. Treaty relations change. General political, economic and commercial treaties: cease to be effective. Unless the treaty provides otherwise, the treaty may be reinstated once the war is over. This depends on the intentions of the belligerents on both sides. 3. Economic and trade exchanges are cut off. Therefore, no matter from which point of view, such patent transfer trade cannot continue, and if it does not proceed, there will generally be no legal liability. Because legally, war is also a force majeure. :)
