As far as question #2 goes:
I believe this is already known as far as ownership of equipment. NWBO owns everything, including the lease. They are akin to the Prime Contractor in the ship repair business, among others (or General Contractor in the building business). Advent is the subcontractor in that they are simply a management company for the scientists/technicians who are performing the actual work of manufacturing. They have specialists who have been involved with the manufacture of DCVax and understand it completely. NWBO subcontracts this work as the Prime Contractor so they do not have to deal with all the management, the payroll, payroll taxes, insurance, hiring, etc. I’m not sure why this is an issue to be frank.
As a subcontractor in the ship repair business my specialty was the work. We figured out how to increase efficiency, manage the process, develop new ways of doing our part to add value. The Prime Contractor owned (or leased) the dry docks, the cranes, and the physical plant. They provided the raw materials, sand blasted the steel and provided a primer coat, provided the welding machine bank, the oxygen/acetylene tanks, the cranes, etc. They had a small crew for these things. I had 100 men working for me and supplied the welding rods, the physical torches and hose, the wiring to connect the welding electrodes to the welding machine bank, and any other consumable materials needed to accomplish our work. The Prime Contractor paid us a fee based on weight, i.e. $4/pound of steel replaced. If we did 60 tons of replaced steel we got paid $480,000. We were not some subsidiary or any other entity. We were subcontractors. If I brought a project to the shipyard in the form of a contract we got the work and we got a commission on the sale of the job. It was in our best interest to bring the work to the place we knew, and the place we understood the facility and what the physical plant’s capabilities were. I think the arrangement with Advent is very similar so I’m not sure what the controversy is; this appears like typical Prime-Sub contractor stuff to me.
