Does anyone know what happened to SUMO Electronics?

I just did a web search and found piles of Sumo info…Jason Stoddard of Schiit was very involved, Jim Bongiorno…a Sumo fan Youtube site, etc.

The SUMO trademark appears to have been cancelled in 2009.  Here is the record from the U.S. Trademark and Patent Office --

The company was bought by Califone International in the 1980s.  Here is an interview that mentions it, originally published in 1988.

The former president of Califone, Michael Custer, is now CEO at Chatsworth Products, an IT services company.

Thanks James.
That’s about all I found also.
