The invention relates to a method and a neural network for computer-assisted knowledge management, based on a neural network (1) that is formed by a computer in its memory location. The invention method and neural network are especially for use in a decentralized, computer-assisted patent system that can be used via the Internet system, in the broad sense. The neural network (1) forms a system of artificial intelligence (KI), covering a fundamental knowledge base in the form of computer-readable texts. The neural network (1) consists of elements (2) that are associated with each other and weighted in relation to each other so that the sets of knowledge available can be managed and analyzed in relation to each other by computer means.
