Masimo files lawsuit against Philips for pulse oximetry patent infringement

16 February 2009

Masimo, the inventor of various technologies for pulse oximetry has announced that it has filed a patent infringement suit against Philips Electronics North America Corporation and Philips Medizin Systeme Boblingen Gmbh related to Philips FAST pulse oximetry technology and certain Philips patient monitors.

The suit was brought in the United States District Court for the District of Delaware. Masimo Founder and CEO, Joe E. Kiani, said: "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."

Masimo says that it and Philips continue to be engaged in a long-term OEM agreement and that it intends to comply with the terms of the agreement, continuing to provide Philips with Masimo SET technology for integration into Philips monitoring products, to the benefit of both companies' mutual customers.
