Hi Lois!!!
Based on the wording of the 8-K, no strings attached.
DM had a lien on the Flash-R Portfolio as collateral 1st of all, and if there was a buyout, DM received "15% of the value of the patents." Those liens were released when EDIG terminated the agreement.
No such terms and conditions have been disclosed, which would be considered a material event and EDIG required to add whatever clause there was in that same 8-K. If buyout terms and conditions were to be negotiated at a later date, a new 8-K would surface.
Looks to me we are "safe."
