13. A computer readable medium containing computer code comprising a system for segmenting claims from a patent document, the system comprising: a display device; a segmentation engine configured to extract and receive text from the patent document, the text comprising the claims, wherein the segmentation engine is further configured to divide the text into segments, each of which comprises only one of the claims, and to further divide at least one of the segments into subsegments; wherein the segmentation engine is further configured to segment the subsegments into at least one element phrase; wherein the segmentation engine is further configured to segment the at least one element phrase into at least one elemental phrase and at least one attribute phrase, wherein the at least one attribute phrase consists of at least one substantive claim limitation, wherein said substantive claim limitation recites a limitation to the invention; and a display engine configured to receive the extracted segments, subsegments and the element phrase, and to display the extracted segments according to a first hierarchal format that indicates a first relationship between the segments and to display the subsegments according to a second hierarchical format that indicates a second relationship between the subsegments and at least one of the segments.
14. The computer readable medium of claim 13 , wherein the first relationship comprises a dependency of one of the first and second claims on the other of the first and second claims; and wherein the segmentation engine is further configured to segment the preamble into a title phrase and an attribute phrase.
