Glad to help! I deal with engineering-related patent stuff (e.g., electrical, mechanical) in my day to day, so feel free to let me know if you are curious about certain aspects of patents. I haven't had a chance to look in detail at the big pharma patents listed above. But, patents can only be directed to man-made stuff (i.e., cannot claim a law of nature or natural substance on its own, although you can claim things like an inventive way to use something natural). Probably not a surprise to anyone here, but a quick glance at the SARs patent 8,506,968 and the Coronovirus patent 10,130,701 shows that they patented the composition of their man-made viral particles..
