Intangible Assets refer to identifiable non-monetary assets that have no physical form and are owned or controlled by enterprises. Intangible assets can be divided into broad sense and narrow sense. In broad sense, intangible assets include monetary funds, accounts receivable, financial assets, long-term equity investment, patent rights, trademark rights, etc. Because they have no material entities, they are manifested as some legal rights or technologies. However, intangible assets are usually understood in a narrow sense in accounting, that is, patent rights and trademark rights are called intangible assets.
