I used to belong to the IEEE, I've not been overly impressed with them of late, especially some of their pro-patent nonsense, like when they were saying that software isn't math. They then went on to describe what is essentially the successor function while claiming it's only meaningful in programming and not math... Anyhow, as you point out, expert witnesses are valued largely by their credentials, so at least that guy has done something worthwhile in tech, which is more than I can say for the plaintiff in this case.
