A design which distinguishes the goods of one producer from those of others is called a "trade mark". A trade mark is a unique symbol, design, or word that is used to identify and distinguish the goods or services of one business from those of another. For example, the Nike "swoosh" symbol is a trade mark that distinguishes Nike's products from those of other sportswear brands. The trade mark helps consumers identify and choose Nike products over competitors' products. Trade marks are important for businesses because they help to build brand recognition and loyalty. They also protect businesses from other companies using their brand to sell similar products or services, which could result in consumer confusion or damage to the business's reputation. In order to protect their trade mark, businesses can register it with the appropriate government agency, such as the United States Patent and Trademark Office (USPTO). This gives the business exclusive rights to use the trade mark in commerce and allows them to take legal action against any other businesses that infringe on their trade mark rights.
