Judge Alsup is of a different school. He is definitely "hands on" and handles cases in ways that put the parties under significant pressure to trim their marginal claims and defenses, to scale back on wild discovery forays, and to give serious consideration to getting to an expeditious trial (or settling) rather than potentially be steamrolled by the judge (for example, as he has impliedly threatened to do to Oracle, if it otherwise did not trim its wilder claims, by sending it packing while he stays the litigation pending patent reexaminations). One can agree or not with such a style and it can sometimes border on judicial abuse but it definitely leads to leaner dockets and calendars that are far less cluttered with marginal garbage than one would find on the docket of a more latitudinarian judge. A good (but strict and tough) judge will only play this out in areas where the judge has lawful discretion to make such calls because trying to force things that are plainly against the rules is abusive, leads to injustice, and makes for hack judging. When a judge is tough in the right sense, however, it is amazing to watch how this can trim the excesses of the adversary system and lead to better justice than would otherwise be the case if the parties were simply allowed to run wild.
The arm-twisting that is evident in the appointment of the court's own expert on damages is a direct message to both parties that they should refrain from going to wildly speculative extremes and focus on credible claims of damages only. Since there is Ninth Circuit authority for such an appointment, this is not overtly out-of-bounds for the judge to do but it is definitely aggressive and does pose a risk of prejudicing jurors if not properly handled. Reasonable minds can differ on this one but, in terms of case handling, this is one more in a series of examples of a judge suffering no nonsense in his courtroom and is at that level quite admirable.
