A formula, practice, process, design, instrument, pattern, or compilation of information used by a business to obtain an advantage over competitors within the same industry or profession
A formula, practice, device, idea, process, design, instrument, pattern, or compilation of information which is not patented and which is used by the owner to obtain an advantage over competitor within the marketplace and is treated in a way that can reasonably be expected to prevent the public or competitors from learning about it except when there is improper access, eavesdropping, data acquisition or theft (where the country's law recognises theft) of that trade secret and where the implementation of the trade secret does not allow reverse engineering
A trade secret is a piece of knowledge that you have, especially about how to do something, that you are not willing to tell other people. I'd rather not talk about it too much because I don't like giving trade secrets away. A secret formula, method, or device that gives one an advantage over competitors
A trade secret is information that is known, used, and kept secret by a particular firm, for example about a method of production or a chemical process. The nature of the polymer is currently a trade secret
