Trademarks are intangible assets of an enterprise. There is no fixed determination of the value of a trademark. The value of a trademark as an asset in the investment or business process is the amount of capital contained in the trademark asset. It refers to its capital value, not its honorary or subjective value. Common value judgments are usually determined by the awareness and recognition of the trademark, and are evaluated based on the estimated value that the trademark can bring to the enterprise.
