SmartMetric Inc., a maker of biometric smart cards, failed in its appeal of a court decision saying Visa Inc. and MasterCard Inc. don't infringe a patent for credit and debit cards containing chips.
In October 2013, in a nonjury trial, a federal court in Los Angeles found that the two credit-card companies didn't infringe patent 6,792,464. SmartMetric had sought damages in excess of $13 billion.
On Aug. 13 the U.S. Court of Appeals for the Federal Circuit, the Washington-based court that hears appeals of patent cases, affirmed the lower-court ruling without comment.
The lower court case is SmartMetric Inc. v. MasterCard International Inc., 11-cv-07126, U.S. District Court, Central District of California (Los Angeles). The appeal is SmartMetric Inc. v. Mastercard International Inc., 14-0937, U.S. Court of Appeals for the Federal Circuit (Washington).
