Review of Patents Issued to Computer Architecture Companies in 2021—Part II

In the last article (Part I), which appeared in the March/April 2022 issue of IEEE Micro, the following was analyzed: 1) the number of all patents and the number of computer architecture patents issued in 2021 and 2) the distribution of those patents across patent classes, for 18 computer architecture companies. The author then presented a notable patent for five of those companies. This article presents a notable patent for the remaining companies. As described in more detail in the previous article, each of the following patents is from the G06F (“Electric digital data processing”) patent class as that patent class had the largest number of patents for all but three companies and because it was the only patent class where all companies had a least one patent. Furthermore, the below patents are from large patent families, which are generally considered to be more valuable.
