Reexam of Flash Memory ‘737 and ‘774 Patents Favorably Concluded

(SAN DIEGO, CA, – September 25, 2012) – e.Digital Corporation (OTCQB: EDIG), a long standing source of innovation and future-defining patented technologies, today reported that the United States Patent and Trademark Office (USPTO) has accepted its supplemental declaration filed in response to an earlier rejection by the USPTO of one claim in the Company’s patent US 5,742,737. “We are very pleased with the USPTO’s decision to admit our supplemental declaration thereby allowing the original claim without substantive modification,” said Fred Falk, president and CEO of e.Digital Corporation.

“This concludes the reexamination of the ‘737 patent, and along with previous modifications to our ‘774 patent announced in May 2012, concludes all open reexamination matters,” added Falk. “Overall we believe the reexam process has strengthened and reaffirmed important patent claims allowing us to aggressively move forward with Flash-R patent portfolio monetization activities.”
