Intellectual property is an intangible creation of the human mind, usually expressed or translated into a tangible form, that is assigned certain rights of property. Examples of intellectual property include an author's copyright on a book or article, a distinctive logo design representing a soft drink company and its products, unique design elements of a web site, or a patent on the process to manufacture chewing gum. Intellectual property law covers the protection of copyrights, patents, trademarks, and trade secrets, as well as other legal areas, such as unfair competition. In effect, intellectual property laws give the creator of a new and unique product or idea a temporary monopoly on its use. The value of intellectual property to an individual or company is not based on physical properties, such as size and structure. Instead, intellectual property is valuable because it represents ownership and an exclusive right to use, manufacture, reproduce, or promote a unique creation or idea. In this way, it is perhaps the most valuable asset a person or small business can own.
