Sonitor® Technologies Wins Patent Dispute With CenTrak

Stamford, CT (August 30, 2017) Sonitor Technologies, a global leader in indoor, ultrasound-based positioning technologies today announced that it has won its patent dispute with CenTrak. In a decision dated August 30, 2017, the United States District Court in Delaware ruled that Sonitor does not infringe CenTrak's U.S. Patent No. 8,604,909, and that CenTrak's patent is invalid.

CenTrak had sued Sonitor in February 2014, accusing the Sonitor Senseâ„¢ products of infringement of that patent. The court first found that there was no evidence to support a finding of infringement by Sonitor. The court also held that Sonitor had demonstrated that all claims of CenTrak's patent are invalid because the patent does not disclose an ultrasonic real-time location system (RTLS), noting that ultrasound is "fundamentally different" than the CenTrak infrared technology disclosed in the patent.

"We are extremely pleased with the Court's decision and have always believed that we would prevail in this case," said Arne Oyen, Group President & CEO at Sonitor Technologies AS. Anne Bugge, President and CEO, Sonitor Technologies, Inc. added, "This decision solidifies and further vindicates and supports our leading position in ultrasound-based indoor positioning and RTLS."
