This is a pretty exciting case: it's in the International Trade Commission (ITC), which is an administrative law court belonging to the US Department of Commerce. ITC cases are similar to patent cases in district court except for two things: first, there's no jury, and second, the schedule is compressed so that you're very busy! The advantage to the ITC from the plaintiff's point of view is that unlike district court judgements, which you pretty well have to enforce yourself, an ITC judgement directs the Customs Service to refuse infringing goods entry into the US.
The case covers some very complex technology: automatic aberration correction for deep-UV step-and-scan tools for semiconductor lithography. These things cost tens of millions of dollars each, and are what makes modern lithography possible. Aberrations are measured using moire or interferometric methods, and then corrected by microscopic tilts of the lens elements, all under computer control.
