A trademark is a recognizable sign, design, expression, or logo used to identify products or services of a particular source from those of others. It can be a word, phrase, symbol, or combination thereof. Trademarks are legally protected intellectual property assets that help consumers distinguish between different brands and ensure that businesses can maintain their unique identity in the marketplace. Registering a trademark provides exclusive rights to use the mark in connection with specific goods or services within a particular geographic area, offering legal protection against unauthorized use by competitors.
