In an example embodiment, there is a method of maintaining a database of patent claim entries. The patent claim entries are associated with one or more patent documents as well as one or more parameters characterizing a patent claim. The database may be accessed to retrieve a selection of one or more patent claim entries. This may be accomplished by retrieving the one or more parameters associated with the selection of the one or more patent claim entries. Additionally, one or more of the parameters characterizing a patent claims may be selected. A report chart is presented on a display device. The report chart depicts relationships between the selected parameters and the one or more patent claim entries retrieved from the database. The relationships are depicted as a plurality of data points. Also a visualization option may be selected and the report chart may be modified based on the selection. The visualization options may include highlighting related data points, presenting claim language associated with a data point, and presenting more parameters associated with the data point.
