The Concept of Sale in the 1980 Convention on International Sale and the US Uniform Commercial Code extending the Territory of Sale from Tangible to Intangible Property

Today, one of the axes of sales development is looking at the territory of the seller from tangible to intangible property. The Convention on the International Sale of Goods does not provide a definition of "sale" and under the provisions of the United States Commercial Code, a contract of sale is an ownership contract and the buyer becomes the owner of the goods in return for payment. The method of research is analytical-descriptive and the question is whether the development of the territory of the seller from tangible to the intangible property conflicts with the legal system of our country or the concept of sale is different in the International Convention on American Commercial Code? The hypothesis seems that the development of the concept of sale by expanding the territory of the seller from tangible to intangible property, without conflicting with the legal system of our country, is justifiable.
