Compressed in as little as a word or two, or perhaps an expressive phrase, trademarks communicate powerful stories about who businesses are and what they stand for. They are at once guardians of reputations, ambassadors of goodwill and advocates of consumption. They have two principal functions: distinguishing one business from another and signifying sources of goods or services. Trademarks are accordingly highly prized, and not only by their owners. They are targeted by predators in both the physical and cyber marketplaces. Thus, the need for owners' constant vigilance to police their marks and protect their integrity. This cannot be done without having an informed understanding of venues and remedies for infringement.
