SAN DIEGO, CA, Oct 09, 2013 (Marketwired via COMTEX) -- e.Digital Corporation
(OTCQB: EDIG), a long standing source of innovation and future-defining patented
technologies, today announced that it has, through its law firm Handal &
Associates, filed a notice of appeal to the Federal Circuit Court of Appeals,
formally challenging the ruling by the Honorable Judge Dana Sabraw to apply the
collateral estoppel doctrine in e.Digital's recent string of cases to enforce
its Flash-R(TM) patent portfolio.

e.Digital filed multiple law suits in the Federal Court in and for the Southern
District of California asserting claims of patent infringement against several
companies. The defendants as a group filed a joint motion asking the District
Court to prevent the Company from relitigating the meaning of certain terms of
the Company's US Patent No. 5,491,774 ("the '774 patent") and US Patent No.
5,839,108 ("the '108 patent") as defined by the judge in the Company's 2010
Colorado litigation against a separate group of defendants. The Company's law
firm opposed the motion on a number of grounds. If successful, the Company's
appeal will require the District Court to take a fresh look at the meaning of
those claim terms and allow e.Digital to argue a different meaning of certain
claim terms in light of, among other things, proceedings before the U.S. Patent
and Trademark Office that took place after the conclusion of the Colorado case.
A reversal of Judge Sabraw's collateral estoppel ruling could also have a
substantial impact on unresolved cases by potentially requiring the Court to
hold a new claim construction hearing on the disputed terms of the '774 patent
and the '108 patent.

"e.Digital takes very seriously its obligations to its shareholders and will
therefore take every step it can to defend the Company's intellectual
properties," said Fred Falk, president and CEO of e.Digital.
