Excellent reference post, particularly for some of the new patents.
Looking again at that Canadien patent, and the changes made in May 2020, before allowance by November 19, 2020, upcoming issuance on Jan 11, 2022, and finally, no expiration until at least December 8, 2025, I believe I am seeing another little manufacturing (secret recipe) detail revealed.
I think there will also be some extension time allowed on that patent and its future twin patents as it undoubtedly moves across the international patent highway.
There’s something about the timing above that provides a sense of hope, moving forward, after this long struggle.
Meanwhile, awaiting the next step — Aka: Sawston GMP certification.
Note: NWBO clearly held off years to make the final move on that Canadien patent. I think that was primarily not to prematurely alert the competition.
