The base patent, control # 12/891,875 issued Nov 1

Nunchi is not a new mobile phone, not an  application and many people are surprised to find that mobile devices are actually only a part of the Nunchi framework. Nunchi is a technology which retrieves data from an array of existing mobile phone sensors and uses this information to recognize, understand and affect interactions among people. 

Nunchi based services utilize cloud-based servers, existing communication networks, sensor fusion, adaptive algorithms and relational databases to understand and anticipate the needs of people. The actual effect of Nunchi ranges from simplistic tasks such as communication screening (based on the user’s availability and the nature of the call) to much more complex tasks such as optimizing a user’s interactions and activities to enrich their lives.

Me again...

When a new idea comes up, EDIG files add on patent apps and claims them to be the benefit of it's base 875.  All of them are called continuation patent applications.

The same thing was done with the Flash-R Patent Portfolio.  774 was 1st, then 4 more followed.  Each addition to the base makes the portfolio stronger, boxing out the competition to a degree.

Very smart move on EDIG's part to continue strengthening it's platform.
