DM remained with the encryption patent pending part (11/522,000) which is no longer as of 4-30-14.
There are I believe 2 settlements from the CO 19 that are paid once per year as royalties, which totals per year about 35 or 40K? I can't remember which 2, maybe all 3 of: Ikagami, Woverine and Roland.
DM gets their 40% plus misc expenes as per the settlement agreement until it's expiration.
To my limited knowledge/memory, this is all that's left with DM.
