Balloting errors in Florida were once again the subject of a legal dispute during this year’s election. But this time is was about patent infringement.

The day before the 2012 election, the U.S. Court of Appeals for the Federal Circuit affirmed a federal district court’s summary judgment findings of invalidity and non-infringement in a dispute about patents for electronic voting machines in Voter Verified v. Premier Election Solutions, No. 2011-1553, 2012-1017 (Nov. 5, 2012). The Federal Circuit’s ruling was coincidentally issued the day before the 2012 election.
