Appellate Decisionmaking: Unanimity or Dissent

The graph above is based on a review of almost 400 CAFC patent decisions that include a dissent. To calculate the percent of patent decisions that include a dissent, I pulled each decision associated with each judge and then added up the number of decisions that involved a dissent (regardless of whether the judge in question dissented). I am confident in these results, but a little more work is needed to handle the en banc decisions (which are more likely to involve a dissent). My RA Ryan Starnes helped in compiling the data.
