Court Upholds Award of $467 Million to Masimo for Philips' Patent Infringement

May 19, 2015

IRVINE, CA -- (Marketwired) -- 05/19/15 -- Masimo (NASDAQ: MASI), inventor of breakthrough noninvasive Measure-through Motion and Low Perfusion™ pulse oximetry and rainbow® Pulse CO-Oximetry™, announced today that the Delaware federal court upheld a jury verdict of $467 million against Philips Electronics North American Corporation and Philips Medizin Systeme Boblingen GMBH for infringing two Masimo patents.

In so doing, the District Court rejected all of Philips' numerous invalidity challenges, denied Philips' motion for a new trial, denied Philips' motion to lower the damages award, and held that Masimo did not commit inequitable conduct in obtaining one of the infringed patents. Because the District Court also determined that Philips had pled a misuse defense, which had been stayed earlier in the case, the court asked that the parties submit proposals on how to proceed.

After years of unsuccessfully trying to reach an out-of-court solution to Philips' patent infringement of Masimo's breakthrough Measure-through Motion and Low Perfusion pulse oximetry technology, on Feb. 3, 2009, Masimo filed its patent infringement action in Delaware. Philips asserted, among other things, that it did not infringe Masimo's patents, although it later conceded infringement, and then argued Masimo's patents were invalid. After a 10-day trial, a jury on Oct. 1, 2014 returned a verdict in favor of Masimo on every issue and awarded Masimo$466,774,783 in damages.

Joe Kiani, founder and CEO of Masimo, said, "This ruling reaffirms Masimo's innovative creation of measure-through-motion pulse oximetry that has dramatically improved patient care worldwide."

About Masimo:
Masimo (NASDAQ: MASI) is a global leader in innovative noninvasive monitoring technologies that significantly improve patient care-helping solve "unsolvable" problems. In 1995, the company debuted Measure-Through Motion and Low Perfusion™ pulse oximetry, known as Masimo SET®, which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies have shown that Masimo SET® outperforms other pulse oximetry technologies, even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced rainbow SET® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI).
