What is "know-how"?

Proprietary technology refers to the unique and novel design, modeling, formula, structure and technology of products, which does not need to be registered in the patent office, but is similar to patent right and has the nature of monopolizing the production and sales of goods, but it is not protected by law and has no clear terms, but it can be effectively used and can be taught and transferred with compensation. Refers to the advanced and practical technical secrets that have not been patented, including design drawings, formulas, data formulas, and the experience and knowledge of technicians. Proprietary technology is also called "technical secret" and "technical know-how". With the emergence of a large number of technical assistance contracts, this is a term often used in contracts. So far, there is no accepted definition of know-how in the world.

The National Bureau of the World Intellectual Property Organization has given the following definition in the Model Invention Law of Developing Countries formulated by 1964: "The so-called proprietary technology refers to the manufacturing process and the use and knowledge of industrial technology". In the Dictionary of Modern Economic Law published by Peking University Publishing House, the definition of proprietary technology is: "Proprietary technology is technical knowledge, technical information, experience, methods or their combination that has certain value, can be used, is unknown to the public, and can be transferred or taught, and does not enjoy patent rights." In a word, proprietary technology is the sum of secret technology knowledge, experience and skills. It can be expressed as written materials, such as design drawings, design schemes, operating procedure guidelines, data, etc. It can also be manifested in the technical demonstration, training and oral teaching of engineering and technical personnel. But as far as proprietary technology itself is concerned, it is an idea and concept contained in these forms of expression.
