infringe the Company's U.S. patents covering the use of flash memory
technologies. The patents in question are a part of e.Digital's
Flash-R(TM) patent portfolio. The recent filings bring the number of
cases currently on file against defendants alleged to infringe the
Company's patents to a total of twenty-one.  
The filings are against Motorola Mobility LLC, Apple Inc., Research
In Motion Limited dba BlackBerry, Research In Motion Corporation dba
BlackBerry, Huawei Technologies Co., Ltd., Futurewei Technologies,
Inc. dba Huawei Technologies (USA), Huawei Device USA, Inc., ZTE
Corporation, and ZTE (USA) Inc. all of whom the Company believes make
or sell infringing products. Along with them e.Digital has named
several of their distributors and retailers who are believed to carry
and sell infringing products. These distributors and retailers

The suits allege infringement of multiple claims across several
patents covering a broad spectrum of products. Notably, the suits
seek infringement damages against smartphones and tablets for
features related to, among other things, flash memory integrity
testing, noise suppression technology and file management
"The Flash-R patent portfolio is rich in technologies and teachings
that are central to the functionality of many current consumer
electronics products," said Anton
 Handal, counsel for e.Digital
Corporation. "Among these is the noise cancellation claims of the
'108 patent, which, generally speaking, teach the use of two
microphones in handheld devices to reduce background noise. We are
also seeing the use of file editing functionalities in these products
that are embodied in the '170 patent. In addition, we are seeing many
flash-based devices utilizing a memory integrity technology that was
patented by e.Digital. Determining memory integrity is very important
technology in today's highly-integrated consumer electronics." 
"We are very pleased with the progress Handal & Associates has made
in continuing to monetize our Flash-R patent portfolio," said Fred
Falk, president and CEO of e.Digital. "They have a comprehensive
understanding of the entire patent portfolio and are leveraging that
knowledge to continue to broaden our licensing opportunities. We
expect to file additional lawsuits throughout our new fiscal year as
we continue to gain momentum."
