I’ve only watched a little bit so far and looked up the first two or three patents he listed. If you read one of the patents, it is often over my head and they are long documents, but you can get the gist of what they are applying for. (Of note, can you patent a genome, even a genome you manipulated? That is a good question For another day). That guy may know patents but it doesn’t seem like he know science that well. Just because there are patents for a coronavirus prior to SARS (one of the patents were for some coronavirus that infects pigs or some other mammal) doesn’t mean it has anything to do with the subsequent 2002-2003 SARS outbreak. There are labs all over the world that work with these viruses, funded by NIADH, pharma, other countries. If you start out with one that infects pigs/rabbits/whatever you can work on developing a vaccine for the animal, wheather mRNA or a traditional vaccine. If they were work on the animal and are safe, that is a bridge to a human vaccine. Back in the 2000s they only knew of 3 or so corona viruses that infected humans. The “patents” appear to have nothing to do with human coronavirus. The only way to know if these “patents” had anything to do with this outbreak is you have to see the genome/what animal infected/similarity to humans/what type of genetic manipulation they were doing and see how close it is to the current sars Cov 2. Labs are about getting funding, writing grants, and everyone making money. Just because they are working on how to develop a vaccine and messing around with coronavirus has nothing to do with this outbreak - except for the Wuhan lab, anything Fauci, or his cronies that shunted money to Wuhan, or labs that worked on similar human related corona viruses. But all those previous patents, research, vaccine stuff ultimately led to the purposeful or accidental release of the Kung Flu.
I haven’t gotten to far so I don’t know about the more recent patents but I would take what this guy says as very suspect with what I have heard so far.
