Inventors

The named inventors are Valentina Dargam and Joshua Hutcheson. Both were employed by Florida International University (FIU) at the time of filing, as indicated by the assignment of their interest to "THE FLORIDA INTERNATIONAL UNIVERSITY BOARD OF TRUSTEES" (Reel 058909/0423). No unusual patterns, such as departure from the original assignee, are discernable from the provided information.

Original assignee

The original assignee named on the issued patent is Florida International University (FIU). FIU is a public research university whose primary line of business is education and scientific research. As a research institution, FIU develops technologies and intellectual property, which it may then license, rather than directly shipping commercial products embodying the claims. The university is currently operating.
