         InvenSense, Inc. : InvenSense® Provides Legal Matters Update

SUNNYVALE, Calif., May 15, 2013 - InvenSense, Inc. (NYSE: INVN), the leading
provider of MotionTracking^(TM) devices, today provided an update regarding
certain legal matters.

Today InvenSense announced that on May 14, 2013 it brought a legal suit
against ST Microelectronics, Inc. (NYST: STM) in federal court in Marshall,
Texas. In the lawsuit InvenSense alleges that ST Microelectronics infringes 3
of its patents and seeks to prevent ST's unauthorized use of InvenSense
intellectual property and asks that money damages be awarded to InvenSense.
The complaint filed with the court includes diagrams which visually indicate
clear infringement of InvenSense intellectual property patents by ST

InvenSense has been the recognized technology leader for its series of world
first innovations, including:

  o2005: World's first dual-axis gyroscope
  o2009: World's first three-axis gyroscope
  o2011: World's first integrated 6-axis motion sensing product, with a
    3-axis gyroscope and 3-axis accelerometer on the same die
  o2012: World's first 9-axis motion-sensing product including a 3-axis
    compass in the same package as a 3-axis gyroscope and 3-axis accelerometer
    on the same die

ST Microelectronics, Inc. did not develop a two-axis gyroscope for this market
until 2009 and its three-axis gyroscope until 2010. InvenSense continues to
innovate sensor technology with the first integrated six-axis gyroscope and
accelerometer products introduced in 2011.

Historically, one year ago, on May 16, 2012, ST Microelectronics, Inc. (NYST:
STM) elected to pursue a litigation based approach to resolving Intellectual
Property matters between the two companies. On that date, ST filed a complaint
in the Northern District of California alleging that InvenSense infringes 9 of
its patents.

All of ST`s claims asserted in that initial litigation are subject to USPTO
reexamination proceedings. To date, the USPTO has determined that substantial
questions of patentability exist for eight of the nine patents asserted by ST
and has issued office actions rejecting ST`s asserted claims in four of the
patent reexamination requests. In view of the pending USPTO reexaminations,
the United States District Court for Northern California stayed the initial
litigation brought by ST.

On March 12, 2013, despite the findings of the USPTO and the action of the
federal district court in the first case initiated by ST, almost a year later,
ST filed a new complaint with the International Trade Commission (ITC) with
respect to three of the same patents it asserted in the initial federal
district court case, all three of which patents are currently being
re-examined by the USPTO. The claims associated with two of the three ST
patents from the prior case, now in the ITC case, have already been rejected
by the USPTO in initial office actions. ST is also asserting two additional
patents that were not in the initial federal court litigation. InvenSense has
reviewed the claims of the two additional patents asserted by ST in the ITC
matter, and considers ST`s new patent claims to be wholly without merit.
InvenSense is defending itself vigorously before the ITC and has filed
requests for inter partes review citing prior art references for each of the
two additional patents-in-suit with the USPTO.

Management Qualitative Comments
"InvenSense developed the first integrated dual-axis MEMS gyroscope for
consumer electronics applications, and by 2006, its novel applications in
consumer electronics products created very significant customer demand for
similar products," said Alan Krock, vice-president and Chief Financial Officer
of InvenSense. "ST did not enter the consumer MEMS gyroscope market until
2008, when it tried to catch up to InvenSense and target the growing consumer
electronics market. InvenSense expects that ST's entry into these markets
subsequent to InvenSense and related unauthorized use of InvenSense
intellectual property will become most evident through this new court case."
