   InvenSense, Inc. : InvenSense® Announces Stay Motion Court Win in Patent
                  Litigation Brought by ST Microelectronics

SUNNYVALE, Calif., March 6, 2013 - InvenSense, Inc. (NYSE: INVN), the leading
provider of MotionTracking^(TM) devices, today announced that it won its
motion to stay the patent litigation action brought by ST Microelectronics
(ST) (NYSE:STM) in the Northern District of California due to progress in
separate proceedings with the United States Patent Office (USPTO) challenging
the validity of all of ST's asserted patents.

All of ST's claims asserted in this litigation initiated by ST are now subject
to USPTO reexamination proceedings. The USPTO has already determined that
substantial questions of patentability exist for seven of the nine patents
asserted by ST, and USPTO office actions have already issued for four of the
patent reexamination requests. The USPTO has rejected all of ST's asserted
claims in those office actions. In view of the pending reexaminations, the
United States District Court for the Northern California agreed with
InvenSense that it is unnecessary to currently proceed with the litigation
initiated by ST and has granted InvenSense's motion to stay the litigation.

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

On May 16, 2012, despite entering the market for consumer MEMS gyroscopes
years after InvenSense, ST initiated a lawsuit against InvenSense alleging
that InvenSense's leading MEMS solutions infringes nine of ST's patents.
Shortly thereafter, InvenSense filed requests for reexamination of each of the
nine patents-in-suit with the USPTO based on substantial new questions of
patentability related to the claims of the patents-in-suit.

According to the court's order, the case is stayed until the United States
Patent Office completes its reexamination process and ST has completed any
appeals of the Patent Offices findings, at which time the parties are to
provide the court with a status report on the re-examination. InvenSense
believes the reexamination process in the USPTO is an important and useful
step particularly when companies initiate litigation based upon patent claims
that are invalid because of prior art that has not been disclosed or
considered by the USPTO.

Management Qualitative Comments
"We are very pleased with this decision," said Alan Krock, vice-president and
Chief Financial Officer of InvenSense. "The decision provides necessary time
for the United States Patent Office to fully reevaluate ST's patents. Based
upon our work and actual USPTO rulings in this case to date, we expect ST's
patents to be found invalid under the USPTO reexamination proceedings."
