Wasn't there a total of 19 companies listed in the press release and something like 30 companies including all of the different subsidiaries listed in the actual court documents?

From the company website...

Wolverine Data 12-10-09

Ikegami 3-1-10

Roland Systems Group and Roland Corporation 3-9-10

3 settlements out of 19, not 4

I hope that number goes up shortly as in today please!
