A Santa Clara businessman faces up to 240 years in prison after being convicted in federal court in Chicago of defrauding investors of more than $5 million over 13 years, with some of the financing he received coming through crowdfunding methods.

Jeffrey Batio, 50, was found guilty Friday in the U.S. Court for the Northern District of Illinois of all 12 fraud charges brought against him — six counts of wire fraud and six counts of mail fraud — and could receive up to 20 years in prison for each count. Batio’s sentencing has been set for Sept. 3.

The charges stemmed from claims made by two of Batio’s computer businesses, Armada Systems and Idealfuture, which purported to be able to make a portable computer that combined a laptop, tablet and smartphone into a single device. That product was said to be produced under various names, including Stealth, IF Convertible, and Dragonfly Futurefon. Court documents also said that Batio’s companies claimed to make a multi-screen laptop computer called the Radian.

Batio was found to have made “material misrepresentations about his companies and products,” such as saying the products were close to coming to market when, in reality, the devices were nowhere near completion — and wouldn’t be within a stated timeframe.

The jury determined that Batio’s fraud began in 2003 and continued until 2016, with Batio raising more than $700,000 via the Indiegogo crowdfunding site from 2014 to 2016.
