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."
