Intellectual Property

e.Digital owns five patents which it refers to as its Flash-R patent portfolio. The company has made licensing of its patented "MicroOS" flash file system, originally called the "Norris Flash File System" or "NFFS," a priority since 1997. The company says it believes that its patent holdings relating to flash memory are "fundamental and valuable, particularly in the areas of content file management, optimal flash memory management, and in removable flash applications."

In February 2006, e.Digital announced that it was pursuing "monetization" of its patent portfolio.

On December 21, 2006 the company stated to shareholders that it had "identified 174 companies with 1,372 products that appear to employ our patent portfolio." On December 20, 2007 it further expanded its claim by stating: “To date, we have identified annual U.S. revenues of more than $20 billion from what we believe are infringing products from such companies."

In March 2007 the company engaged the law firm of Duane Morris LLP to pursue patent infringement claims on a contingent fee basis. The agreement grants Duane Morris 40 - 50% of all settlements and awards after full reimbursement for expenses incurred. The contigency fee agreement also provides a lien resulting in e.Digital's patents being officially assigned to Duane Morris.
