According to aspects of the present invention, methods, systems, and media are provided for creating, storing, and using an interactive hierarchical arrangement of technical elements useful for conducting efficient patent infringement and similar analysis. The hierarchical arrangement of technical elements is adapted to be displayed on a user-engageable computer display in a manner that allows a user to select and de-select particular technical elements. Methods and systems include storing records of technical elements in hierarchical relationships, which elements are correlated to specific patent claims during an annotation process. The hierarchical arrangement of technical elements is displayed so as to indicate genus-species relationships among the technical elements, while the stored correlations are used as a basis to perform highly efficient claims-based patent analysis.
