NEW YORK (GenomeWeb News) – Caliper Life Sciences has filed a suit against Shimadzu claiming that the Japanese firm's microfluidic system infringes 11 patents held by Caliper.
The suit, which was filed last week in the US District Court for the Eastern District of Texas, alleges that Shimadzu's MCE-202 MultiNA instrument system, a microchip-based electrophoresis system that performs DNA and RNA size confirmation and quantitation, infringes its patents. The Shimadzu instrument uses the microchip technology to conduct fully automated, high-speed electrophoresis separation and uses fluorescence detection to perform high-sensitivity analysis, Caliper said in its suit.
Caliper sells LabChip systems that also conduct electrophoretic DNA separation and IVIS molecular imaging systems using fluorescence and bioluminescence.
Caliper has asked the court to declare that Shimadzu and its American subsidiary, Shimadzu Scientific Instruments, are infringing Caliper's patents. It also has asked the court to enter a permanent injunction barring Shimadzu from selling its microfluidic system, and it has asked for the court to award it triple damages due to alleged willful infringement.
