In fact, most patents are not discovered by accident, but are designed and developed with purpose. For many enterprises, it is a great waste of research and development to manufacture products that others already have or have similar technologies. Some enterprises want to enter the European market and the American market, and after investing a lot of money to prepare the market, they find that the core technology patents of products to be promoted are in the hands of some enterprises in Europe and America. If a clear patent map is set in advance for product patent research and development without touching other people's patents, there will be no dilemma in patent application and a lot of manpower and material resources will not be wasted.
Patent map plays an important role in the utilization of patent information, which refers to sorting, processing, synthesizing and summarizing the retrieved patent information into charts in the form of data for quantitative analysis and qualitative analysis; Enlightenment refers to the comparison, analysis and research of patent maps to make predictions and judgments, so as to obtain the information of available technical level, trends and development trends, and specify business strategies, patent strategies, selected development goals and other services for enterprises. It can be seen that patent map, as a tool for collecting, sorting out and utilizing patent information, is of great significance to enterprises. As early as a few years ago, it was valued and utilized by developed countries and regions. For example, in order to help promote the use of patent information by enterprises, the Japanese government has been collecting and analyzing patent information in every technical field for the past two decades to make patent maps and put these maps on the Internet for free. For example, only in the field of communication, patent maps involve fifteen aspects such as infrared sensing and application, image recognition technology, etc. The Korean Intellectual Property Organization (WIPO) plans to make and promote patent maps in all industrial fields according to the mechanism of its typical project-mobile phone patent map application. In recent 10 years, Taiwan Province Province has also successfully produced patent maps in many fields, such as speech recognition, multi-film module, MPEG video, carbon nanotubes and so on, which has played an important guiding role in the technical research and development and strategic deployment of future products.
