Gemalto has licensed the contactless smart card patent from Leighton Technologies.
The license with Gemalto is an outcome of a patent infringement lawsuit, Leighton Technologies LLC v. United States of America. Gemalto was not a defendant in this lawsuit, but was given notice of the action by the U.S. Government because, as a government vendor, it might have had an interest under applicable law. Gemalto opted to take a license for the Leighton patents on a non-exclusive basis.
The particular Leighton patent covers the manufacturing of the cards or the “hot lamination method for a hybrid radio frequency optical memory card converting sheets into a web process.”
