Masimo filed a patent infringement suit Feb. 3 against Philips Electronics North America Corp. and Philips Medizin Systeme Boblingen Gmbh related to Philips FAST pulse oximetry technology and Philips patient monitors.
The lawsuit was brought to the District of Delaware United States District Court.
“Given that Philips and Masimo have a long-term business relationship, we have patiently tried to resolve our differences regarding Philips' infringement of Masimo's patents without seeking the courts' intervention. Unfortunately, since our best efforts have not been successful, we believe we have no choice but to rely on the courts to resolve this dispute," said Joe E. Kiani, Masimo founder and CEO.
Masimo, the creator of pulse co-oximetry and measure-through motion and low-perfusion pulse oximetry ,and Philips will continue to be engaged in a long-term OEM agreement, despite the lawsuit.
