PORTLAND, Maine — A Pennsylvania man admitted Wednesday in U.S. District Court that he sold fake cellphone covers made to look like OtterBox-brand phone covers to a vendor in Maine.

Michael Kurnik, 25, of York, Pennsylvania, pleaded guilty to conspiring to traffic in counterfeit goods, according to the U.S. attorney’s office. A charge of trafficking in counterfeit goods is expected to be dismissed at sentencing.

His sentencing date was set for Feb. 2.

Kurnik remains free on personal recognizance bail, according to information posted on the court’s electronic case filing system.

By pleading guilty, Kurnik admitted that he regularly purchased what purported to be OtterBox cellphone cases from suppliers in China and resold them to individuals in the United States, according to court documents. These individuals in turn often sold the cases on eBay and other online sites.

One of the resellers, who lived in Maine, told Kurnik in May 2013 that he had been contacted by OtterBox and told that he was going to be sued for selling counterfeit cases on eBay, the U.S. attorney’s office said Wednesday in a press release. In December 2013, Kurnik sent a shipment of counterfeit cases to the reseller in Maine, who was cooperating with law enforcement.

When police searched a warehouse in Manchester, Pennsylvania, that was used by Kurnik, about 6,700 counterfeit OtterBox cases were seized.

Kurnik was arrested July 15 in Pennsylvania after being indicted July 8 by the federal grand jury in Portland, according to a previously published report. The indictment was sealed until his arrest.

Kurnik faces up to 10 years in federal prison and a $2 million fine.

OtterBox was founded in 1998 in Fort Collins, Colorado, according to information posted on its website. The company sells protective cases for cellphones, tablets and other handheld devices.

The investigation was conducted by U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.
