The Delaware Default Standard for Discovery, which has been around in its present form for about a decade now, applies to some extent in every Delaware patent case. Given how frequently discovery issues are litigated in Delaware, I was somewhat surprised to see a new ruling from Judges Connolly and Hall clarifying a bit of the Default Standard that I don't believe has ever come up before.

In the vast majority of patent case in Delaware, the parties are required to serve initial patent disclosures in the form of infringement and invalidity contentions (separate from the contentions they might otherwise serve as part of written discovery). These initial contentions set the stage for fact discovery, claim construction, expert reports, and (in some cases) settlement.

Initial patent disclosures were formalized in this District to some degree by the Court's creation of the Default Standard for Discovery nearly a decade ago. The Default Standard established a staged set of initial disclosures that was eventually adopted by most of the Judges here.
