Most-Cited Opinions

The 100 opinions most often cited by later opinions within this collection, ranked by the number of distinct later opinions that cite them. 466 opinions here are cited at least once.

This counts citations between the 6,707 documents on this site only. It is not a measure of how often a case is cited anywhere — an opinion cited constantly outside the Eastern District of Texas and the Federal Circuit will not show that here.
