SAN DIEGO, CA, Apr 04, 2012 (MARKETWIRE via COMTEX) -- e.Digital Corporation
(OTCBB: EDIG), a leading innovator of dedicated portable entertainment systems
and patented flash memory-related technology, today reported that it will
request amendment of its patent US 5,491,774 in response to a rejection of
certain claims from the United States Patent and Trademark Office (USPTO) which
was recently received. As is customary, e.Digital expects to incorporate
modifications to certain rejected claims while leaving a majority of US
5,491,774 claims unchanged. The Company expects, but cannot assure, that the
planned modifications will overcome the rejection and further believes the
modifications could clarify and strengthen its ability to enforce future
infringement of US 5,491,774.
