2. Analysis Summary: This case is a claim dispute between international buyers and sellers of goods due to the guarantee of goods ownership. According to the facts and the provisions of the United Nations Convention on Contracts for the International Sale of Goods, we (the seller) have the obligation to waive the guarantee of the ownership of the goods, and the French businessman (the buyer) claims that there is insufficient evidence for our claim, so we (the seller) are not responsible for the compensation claimed by the French businessman, which is the focus of the dispute. In this case, we are not responsible for the buyer's claim. 2. Reason: According to the provisions of the United Nations Convention on Contracts for the International Sale of Goods, ① the rights of the third party are obtained according to the laws of the destination country or region where the goods are expected to be sold or used in the contract. In this case, the seller knew or could not have been unaware of the existence of the rights of the third party and should bear the responsibility. (2) Obtaining the rights of a third party according to the laws of the country where the buyer's place of business is located shall be borne by the seller. ③ The Convention also stipulates: "When the buyer knows or cannot be unaware of the intellectual property claims and requirements of a third party when concluding a contract, and the seller sells the goods to a country other than the destination without knowing it, the seller is exempted from the obligation of ownership guarantee." In combination with this case, we (the seller) delivered the goods to the French businessman according to the contract, but we didn't know that the French businessman sold the goods to the United States and European countries other than the destination. In addition, according to French law, French businessmen knew or could not have been unaware of the intellectual property requirements of third parties when concluding contracts. For this reason, we are not responsible for the claims made by French businessmen.
