I see no evidence of that. A search of that # comes back empty. And a search of your Application # returns no patent.

Which is not surprising as it can take several years after filing for a patent to issue. If patent numbers are issued sequentially (I assume they are) then it appears the latest issued US patent is 10,820,461 issued to Kawai on October 27, 2020. That's another way of saying ... they haven't hit 10,999,999 yet.

Perhaps the larger question is ... does David's invention work? Any evidence it can actually prevent or cure COVID-19 in humans?
