You're most welcome. I don't have all of the answers here but I'll give two examples of what I see.

For the first abandoned one in the list (date of 7-8-22), the activity that I'm seeing in Patent Center says that the patent application received a non-final rejection on 12-3-21. Usually when a non-final rejection is received, the applicant has six months to appeal the decision and request continued review (after revising their submittal to address the issues raised in the rejection). The next entry in the file basically just says that the company failed to submit a timely reply in response to the non-final rejection, so it's considered abandoned.

Another example:
On the one that says Expired (non-payment), the last status update in Patent Center says "Patent Expired Due to NonPayment of Maintenance Fees Under 37 CFR 1.362 05/01/2017"

I would like to assume that this isn't just pure negligence in both of these example cases. Perhaps the company decided that it wasn't worth the resources (expensive patent attorney fees) to continue fighting the one that kept getting rejected. Maybe they decided that the one that expired wasn't going to yield any meaningful business impacts going forward. Impossible to know for sure.
