Here is some colorful writing from Magistrate Judge Burke of the District of Delaware, recommending dismissal of a claim for willfulness that failed to plead knowledge, and which relied on—at most—possible knowledge for a 15-hour period between when the complaint was served on an unknown person and when the patent expired:
From the docket, it appears that someone who is in some way affiliated with [defendant] Robinhood was served with the FAC at 9:08 a.m. on July 30, 2019. . . . But, as it turns out, the '633 patent expired on July 30, 2019—that same day. The Court guesses that, in light of all of this, it might be theoretically possible for Plaintiff to pursue what would have to go down as the most de minimis claim of willful infringement in this Court’s history. But whether such a claim—revolving around whether Robinhood knew of the patent and its infringement thereof, during a roughly 15-hour time period on July 30, 2019—would even be plausible would depend on exactly who got served with the Complaint on July 30, 2019 and what their relationship with Robinhood is. Yet the record provides little information on that front. Thus, in the Court’s view, the best course is to grant Robinhood’s Motion as to willful infringement, and if Plaintiff believes it can (and should) pursue such a claim here, then in a further amended pleading, it can attempt to set out the factual basis for such a claim.
