About once a month we provide an update on activity in important patent cases. In particular, we keep track of patent cases pending before panels of the Federal Circuit, where the cases involve at least one amicus brief. We also keep track of non-patent cases that attract amicus briefs, but only once those cases have been scheduled for oral argument. Finally, we also highlight panel cases we find important. You can find all of these cases in the “Other Cases” section of our blog. Today, with respect to these cases, we highlight two patent cases with new briefing, an argument recap in the only such case argued in April, and three upcoming oral arguments in these cases. Here are the details.
