Despite the worsening legal battle between Mitek Systems Inc. and USAA of technology rights this week, Mitek continues to press hard to sell its remote deposit capture product to banks.

Mitek announced today that it has intensified its mobile remote deposit capture technology lawsuit against USAA. Specifically, the San Diego-based vendor has filed a motion in Delaware federal court to amend its complaint to also include two more claims alleged against USAA: defamation and unfair business practices.

“We had to make a public statement,” James DeBello, Mitek CEO and President tells Bank Innovation. “We will defend our rights rigorously.”

The legal war between the bank and vendor first began in late March, when USAA alleged the mobile imaging software vendor stole its mobile RDC trade secrets and technology. In April, Mitek filed a counter suit against USAA.

“USAA is confident in the merits of our case,” a USAA spokesperson told Bank Innovation in an email today. “We look forward to presenting the facts surrounding this case in a court of law.”

Since the legal rumble first begun, DeBello says that banks have launched and gone public with its technology that lets consumers deposit their checks through camera-equipped smartphones. Among the banks on its client roster are Wells Fargo and Citi.

The vendor has signed up 333 banks as of last March, its last announcement period. Next Tuesday, July 24th, Mitek will update its client list.

“More and more people are adapting remote RDC,” he says. “The momentum continues to grow.”

In other words, the heavy sales efforts go on, despite the USAA scrap.
