The products of the human mind are at the root of all business, but they are legally protectable only to a certain degree. Inventions that are truly novel may qualify for a twenty-year patent; the inventor may then prohibit anyone from using the art (machine, process, manufacture, and the like) or license it on his own terms. A business may sue a person who improperly gives away its legitimate trade secrets, but it may not prevent others from using the unpatented trade secret once publicly disclosed. Writers or painters, sculptors, composers, and other creative artists may generally protect the expression of their ideas for the duration of their lives plus seventy years, as long as the ideas are fixed in some tangible medium. That means that they may prevent others from copying their words (or painting, etc.), but they may not prevent anyone from talking about or using their ideas. Finally, one who markets a product or service may protect its trademark or service or other mark that is distinctive or has taken on a secondary meaning, but may lose it if the mark becomes the generic term for the goods or services.
