Carestream Health Inc. accused Caliper Life Sciences Inc. of violating one of its patents, nearly five months after Caliper slapped Carestream with a patent infringement lawsuit of its own.
The Carestream suit, filed in the U.S. District Court for Western Wisconsin, alleges that Hopkinton, Mass.-based Caliper infringed Carestream’s patent for "Apparatus and Method for Multi-Modal Imaging" with its Ivis Lumina XR imaging system. Rochester, N.Y.-based Carestream alleged that the willful infringement also included the intent to cause others to infringe the patent, according to court documents. The company is seeking an injunction against further sales of the device, triple damages and attorney’s fees.
In February, Caliper sued Carestream in the U.S. District Court for Eastern Texas over a suite of seven patents it licenses from Stanford University. That lawsuit alleged that Carestream’s In-Vivo Molecular Imaging Solutions and Image Station Molecular Imaging Solutions lines, including a series of Kodak-brand devices Carestream acquired from Eastman Kodak Co. in 2007, infringes the patents covering Caliper subsidiary Xenogen Corp.’s IVIS imaging system. The IVIS devices are used for preclinical non-invasive imaging of mammals covered by the Caliper patents.
