This is compared to what NWBO is listed as the assignee on:
patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&Query=an%2Fnorthwest+and+an%2Fbiotherapeutics&d=PTXT
That lists patents for which NWBO was ever the assignee.
if you want to see current assignee and assignee history, you need to use their assignee search.
For example, if you want to see the current assignee of:
TANGENTIAL FLOW FILTRATION DEVICES AND METHODS FOR LEUKOCYTE ENRICHMENT
Patent:8518636
You need to search like this:
https://assignment.uspto.gov/patent/index.html#/patent/search/resultAbstract?id=8518636&type=patNum
There you will see that it was assigned to Four M along with 19 other NWBO properties (Patents and Patent Applications).
If you click the pdf symbol next to "security agreement" it will open the conveyance document.

Look at the assignment history of one of the older Patent Aps.
Generation of dendritic cells from monocytic dendritic precursor cells with GM-CSF in the absence of additional cytokines
https://assignment.uspto.gov/patent/index.html#/patent/search/resultAbstract?id=10789807&type=applNum
You will see it was assigned to Toucan.
again assigned to Toucan
released from assignment
assigned to Four M
and no subsequent release
My understanding is that Four M is the current assignee on 19 patent properties.
They also hold the second mortgage on Sawston since July 2017
