Your comments regarding the recent financing sound very naive. Do you understand how toxic financings work and why they are called toxic? Do you understand the role that warrants play in these financings and how they are used?
Four M, aka Meheil still owns the patents. NWBO is refusing the repay the very small loans even though at least one is past due. One can only assume that there is an agreement that the sums will never be paid. That's just a way to keep it off the books.
If you don't believe me, just search the USPTO for patents assigned to Four M Purchasers. Actually, just do a google search for Four M Purchasers. You will see for yourself.
Sort by role and you will see the actual scientists assigning their work to NWBO, a normal activity when there is an employee/employer relationship.
If you sort by date you will see the history of all the applications/patents and publications. You will see that on 4/18/2012, virtually all the IP was assigned to Four M. Go back a little to 3/29/2012 you will see that most of the IP was assigned back to NWBO from Toucan Capital Fund II, LP.
In short, the patents/applications/publications were developed by employees, who were paid by the company. The company assigned most of these to Toucan Capital Fund II, LP, which in 2012 reassigned them back to NWBO, which turned around three weeks later and assigned them to Four M Purchasers, which currently is the owner. Not all of these may represent nefarious actions, however the company has chosen not to repay a really small amount of money, to enable the IP to stay in the hands of other owners.
Note that Four M etc owns not just the patents, but also all the patent applications and even the publications of the company on that list, ALL the IP until the loans are repaid, which NWBO has so far refused to do.
