Patent analysis is to analyze, process and sort out the patents of a specific technology or a specific theme, and finally form patent charts at all levels.
Patent analysis is generally divided into patent basic analysis and patent technology analysis. Fundamental analysis is realized by statistical patent description projects, and technical analysis is generally realized by patent indexing. By reading and indexing patent literature, the technology is classified, and finally detailed technical analysis and statistics are formed.
There are also two kinds of patent analysis, one is carried out by the government and the other is carried out by enterprises. The former is an industry patent analysis report issued by Japan Patent Office every year, while the latter is formulated by enterprises according to specific technologies or themes. The main purpose is to guide the project establishment, research and development, grasp the context of technological development, understand hot technologies, avoid patent barriers, find patent gaps for R&D layout, and find basic patents.
