The New Student's Reference Work/Trade-Mark

Trade-Mark, the name or device used to distinguish the merchandise of a firm from that of others. Trade-marks are protected by law in nearly all countries, in order to protect buyers from frauds and enable a merchant or manufacturer to profit by the superiority of his goods. In the United States a merchant or firm registers its trade-mark in the patent-office (q. v.), and is entitled to its use for 30 years and to renew it for 30 years more.
