Research And Application Of The Patent Map

It is revealed by WIPO that over 90% of all the world's inventions are found in patent documents. Additionally, it is also disclosed by EPO that "patents reveal solutions to technical problems, and they represent an inexhaustible source of information: more than 80% of man's technical knowledge is described in patent literature." But patents are often straitjacketed as legal documents that aim to cloak a technology in the name of market interests rather than project it. Therefore two issues arise at the onset when dealing with patents. Patents describe technological innovation in detail, going deeply into the semantics of the subject. The substantive data in a patent document is primarily intended for experts in the field and often, non-specialists in the field cannot evaluate the value of a patent. Furthermore, the data in a patent document does not represent the defacto value of the technology described in that patent if it is evaluated without reference to other patents and competing technologies in the field. It is thus necessary to obtain actionable information from patents using data processing and comparative intelligence tool. Such tools have to serve two purposes - to extract valuable technologies from among a range of patents and present the best implementations for specialists, as well as to present the information in a form palatable to non-specialists. Patent map is a field that has evolved from a simple concept to an important new discipline in intellectual property. Therefore the function, style, procedure and others of patent map is research, and the results indicate:Patent map is at the forefront of such techniques. It is based on clustering, aggregation, and other operations to extract the technological value from patents in...
