I was curious what IBM still makes that people use since they sold their Thinkpad division to Lenovo years ago, so I googled it:

> IBM produces and sells computer hardware, middleware and software, and provides hosting and consulting services in areas ranging from mainframe computers to nanotechnology. IBM is also a major research organization, holding the record for most U.S. patents generated by a business (as of 2019) for 26 consecutive years.

What on Earth are all of those patents for?
