My only reason to post the article (without comments) was in reference the latest PR when Fred said:

"We are extremely pleased with the grant of our first set of patents teaching context and interpersonal awareness systems," said Fred Falk, president and CEO of e.Digital Corporation. "These patents are foundational of the larger Nunchi™ patent portfolio that we expect to play an important role in the future of mobile communications. Additional Nunchi patent applications are in progress that we expect to add value to our portfolio."

We were unclear about the use of teaching (tteddy & others...such as me).
