Leigh M. Rothschild has launched his first new litigation campaign of the year, with Rothschild Biometric Systems, LLC—a recently formed entity managed by the inventor—asserting a single user verification patent (8,799,088) against USAA Bank (2:17-cv-00061). January has also seen a fresh wave of filings in the QR code campaign waged by Symbology Innovations, LLC, another NPE controlled by Rothschild.
