Visualizing patent data using hyperbolic tree

The paper reviews the basic principles, technical implementation of the hyperbolic tree, and its shortcomings in application of patent analysis. And then, the paper designs and realizes three applications of the hyperbolic tree to visualize the patent data for improving the data utilization efficiency of the patent citations, patent families and patent claims. For the patent citation visualization, the user-concerned patent citations are added into the hyperbolic tree for display based on the users' demands, and the tree hierarchy is not limited, which expends the applications of the hyperbolic tree in the patent citations. For the patent family visualization, the priority node and state mode are established, so that his users could quickly and easily access "where the patent being does analyzed have the family, what is the priority date, and which country the patent is from". For the patent claim visualization, the independent claims and the dependent claims are merged into the hyperbolic tree, thus the users could easily understand the contents of the independent claims and the dependent claims, and their dependencies.
