STMicroelectronics Re-Asserts Its MEMS Patent Leadership and Requests 
International Trade Commission Investigation of InvenSense 
COPPELL, TX -- (Marketwire) -- 03/11/13 --  STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the
spectrum of electronics applications and the worldwide technology
leader of motion, environmental, audio and micro-fluidic MEMS
(Micro-Electro-Mechanical Systems), announced today that its U.S.
subsidiary, STMicroelectronics, Inc., has filed a complaint with the
United States International Trade Commission (ITC). The complaint
requests that the ITC initiate an investigation into the alleged
infringement of five ST patents covering all of InvenSense, Inc.'s
MEMS device offerings, as well as products from two of InvenSense's
customers, Black and Decker, Inc. and Roku, Inc. ST has requested
that the ITC issue an order excluding InvenSense's infringing
gyroscopes and accelerometers, as well its customers' products that
include those InvenSense devices, from importation into the United
This is the second patent lawsuit that ST has brought against
InvenSense. In May 2012, ST filed a patent infringement lawsuit
against InvenSense in the Northern District of California, alleging
infringement of nine ST patents and seeking injunctive relief and
monetary damages. Rather than litigating ST's claims before the
court, InvenSense used the delaying tactic of filing requests for ex
parte reexamination of ST's patents with the United Stated Patent and
Trademark Office ("USPTO"), even though historically over 89% of
reexamined patents are confirmed upon ex parte reexamination. 
On February 27th, 2013, the district court granted InvenSense's
request for a stay of proceedings pending the USPTO's reexamination.
ST is confident in the validity of its patents and is eager to resume
the district court proceedings at the earliest opportunity.  
"While we welcome fair competition, ST cannot tolerate continued
infringement of our strong and unique patent portfolio, which is the
result of more than 15 years of intensive R&D efforts and substantial
investment, to bring competitive and innovative solutions to
customers worldwide," said Bob Krysiak, President and Chief Executive
Officer of STMicroelectronics, Inc. 
With mo
re than 800 MEMS-related patents and patent applications
worldwide, including more than 350 in the US, ST is the acknowledged
world leader in motion, environmental, audio, and micro-fluidic MEMS,
and leads the way towards intelligent and independent sensing
devices. The company's comprehensive portfolio of micro-machined
accelerometers, gyroscopes, pressure sensors, magnetic sensors, and
microphones -- together with its manufacturing and packaging prowess
and ability to integrate multi-sensor combos with on-board signal
processing, control functions, sensor-fusion algorithms, and wireless
connectivity -- aim to open new horizons in consumer electronics,
healthcare, environmental sciences, and many other domains.
