Research On Patent Innovation Guider Based On Citation Path Analysis

Patent map is the way to visualize patents, systemically manage patents and assist in establishing patent strategy. Citation path analysis statistics, concludes and compares the citation information. And it is the metric way to visualize the citation information, open out the citation quantity characters and inter rules. This paper presents patent innovation guider based on patent citation database. This kind of map combines patents visualization with patent technology map and adds the analysis of patent technology development in time serial. This way makes patent innovation guider differentiate from other patent maps. Patent innovation guider can clear technology developing skeletons, dig technology hotspots, forecast technology developing ways and confirm competitors.This paper contains the following studies and results:①It definitely presents the principle of patent innovation guider based on citation path analysis. We consider that via analyzing patent citations, visualizing patent citation paths and analyzing the development of citing relations, the map can clearly exhibit the technology innovation path, namely the origin, development and technology manufactures.②It definitely presents that in order to draw patent innovation guider, it is necessary to create the subject patent citation database. And this paper systematically designed the way to create the subject patent citation database.③It systematically designs the qualifications, approaches and effecting factors of drawing patent innovation guider. The approaches of making patent innovation guider includes collecting patents, creating patent citation database, re-clarifying patents, making matrix map of patent technology & efficacy, analyzing patent citation paths and making patent innovation guider.④This paper takes medical endoscope patents as the case. According to above ways and approaches, it created the endoscope patent citation database. It statistics and analyzes the source patents and cites patents of endoscope and backward searches the cited patents. Combining with the citation path analysis, this paper arranges patents in time serial, makes endoscope matrix map of patent technology & efficacy, endoscope patents citation path analysis map and endoscope patent innovation guider. It also analyzes the developing course of endoscope from fiberscope to capsule endoscope, and forecasts the developing direction of endoscope. This case absolutely approves the way of making patent innovation guider based on citation path analysis is feasible and effective.
