Here is an update on activity in cases pending before panels of the Federal Circuit where the case involves at least one amicus brief. We keep track of these cases in the “Other Cases” section of our blog. Today with respect to these cases we highlight two new response briefs, one in a case raising questions related to whether a district court erred in denying a motion to intervene and to unseal court records and another in a patent case involving a challenge to a district court’s injunction requiring the delisting of patents from the Food and Drug Administration’s Orange Book; two new reply briefs, one in a patent case raising questions related to eligibility, claim construction, and infringement and another in a patent case raising questions related to eligibility; and five new amicus briefs in the patent case challenging the delisting of patents from the Orange Book. Here are the details.
