Knobbe Martens Again Successfully Defends Masimo in Litigation


is pleased to announce that it has obtained a dismissal of
patent litigation brought by Dominion Assets LLC ("Dominion") against
longtime Knobbe client Masimo
. This is the fourth patent case against Masimo by an
entity not practicing the asserted patents, all dismissed with no
payment by Masimo.

"We would not be able to stand up to bullies and opportunists if it were
not for the talented lawyers from Knobbe Martens," stated Joe Kiani,
Masimo's founder and CEO. "We value our long history with this
world-class team."

Knobbe Martens Partner Stephen
remarked, "It's great to have a client that is principled and
will not simply pay to settle when they know they are right. Our firm
has been honored to represent Masimo from its earliest days, helping
Masimo protect and defend its revolutionary pulse oximetry and Pulse
CO-Oximetry to the benefit of patients worldwide."

In 2012, Dominion filed a lawsuit alleging that Masimo infringed three
United States patents related to noninvasive blood analyte measurement.
In 2014, the court granted Masimo's motion to dismiss the case. After
Dominion refiled, dropping one of its patents, the court agreed with
Masimo that several asserted claims were indefinite, and thus invalid.
In 2016, Masimo prevailed on summary judgment of invalidity of one
Dominion patent on two separate grounds. Recently, Masimo narrowed the
case to one asserted claim of a single patent.

On August 14, 2018, Knobbe obtained a dismissal of the case with
prejudice and a covenant not to sue Masimo on all of Dominion's patents.
