Know-how means any form of technical information or assistance relating to the manufacture or placing into operation of the said products. It also means any practical knowledge, techniques, and skill that are required to achieve some practical end. It is considered a intangible property in which rights may be bought and sold. Know-how also means the technical skill which large groups of men acquire through extensively financed experimentation and cooperation.
The following is a case law defining know-how:
Know-how is generally defined as factual knowledge not capable of precise, separate description. However when used in an accumulated form, after being acquired as the result of trial and error, gives to the one acquiring it an ability to produce something which otherwise would not have known how to produce with the same accuracy or precision found necessary for commercial success.[ Hooker Chemical Corp. v. Velsicol Chemical Corp., 235 F. Supp. 412 (W.D. Tenn. 1964)].
