context: Trademarks existed in the ancient world. 3000 ago, Indian artisans used to imprint their signatures on artistic creations before sending them to Iran. Later, about a thousand different Roman pottery brands were used, including the FORTIS factory brand, which became so famous that it was copied and faked. One of the first brands of packaged goods - (red wine) - was used in Pompeii about 2000 ago. The name of the product is derived from the Latin words (Vesuvius) and (wine) [5]. The use of trademarks has grown in the face of flourishing trade in the Middle Ages.
