In world of 360-degree video, a claim of patent infringement

April 12, 2011 -- A lawsuit filed recently in the U.S. District Court, Northern District of Illinois, alleges patent infringement in the area of 360-degree, wide-angle video surveillance technology.

A statement from Grandeye Ltd. alleges that Sentry360 violated a nondisclosure agreement and was "misappropriating Grandeye's information for use in its own products." The full complaint alleges "patent infringement, the misappropriation of trade secrets and breach of contract." Grandeye said it is seeking an injunction against Sentry360 as well as monetary damages.

"Grandeye's management is determined to protect its intellectual property from the continued unlawful use by Sentry360," said Paul Storm, a partner at the Dallas, Texas-based law firm of Storm LLP and a specialist in intellectual-property cases.

A statement from Sentry360 called the allegations "without legal basis" and "wrongfully filed," and the company said that allegations from Grandeye that Sentry360 had signed a nondisclosure in 2006 were simply "untrue."

"The patents about which Grandeye has filed the lawsuit were assigned to it by another party in December, 2009," said Sentry360 President and CEO Thomas Carnevale in a statement provided to "Sentry 360 signed a limited confidentiality agreement in 2006 in order to become a reseller for products. No proprietary information was given by Grandeye or used by Sentry360."

Carnevale added that his company "extremely surprised" when Grandeye filed suit.

"No prior notice of Grandeye's claim of purported infringement was given," wrote Carnevale. "Despite the greater resources of Grandeye, Sentry intends to challenge Grandeye's efforts to block legitimate competition and innovation in this area."

The technology in question dates back to the days of IPIX, a since-defunct company offering panoramic, 360-degree video surveillance. Some of IPIX's technology ended up with Sony, but rights to use some of the former IPIX technologies also found their way to Oncam Global Group, the parent company of Grandeye. Dr. James Ionson, CEO of Oncam, was a board member for IPIX.
