Expect Delays

Don't let your discovery motions sit! We got another opinion this month denying a discovery motion in part due to a party's delay, this time from visiting Judge Bibas of the Third Circuit:

ORAL ORDER: I DENY Vertex's motion to strike, D.I. 178 . I apply the Pennypack factors: (1) the surprise or prejudice to Vertex; (2) the ability of Vertex to cure the prejudice; (3) the likelihood of disruption of trial; (4) the bad faith or willfulness involved in not complying with the disclosure rules; and (5) the importance of the evidence sought to be excluded. Meyers v. Pennypack Woods Home Ownership Ass'n, 559 F.2d 894, 90405 (3d Cir. 1977). Lupin had disclosed enough that …

We've been following a series of hearings in Rein Tech, Inc. v. Mueller Systems, LLC, C.A. No. 18-1683-MN (D. Del.), a now-dismissed case where the inventor attempted to serve the expert witness but was excluded due to protective order violations.

The defendant later alleged that the same inventor again violated the protective order by continuing to prosecute another patent application in the same field, despite a prosecution bar.

In response, counsel for the inventor argued that the inventor did sign the prosecution document, but did not "prosecute" the patent:

Although signed by [the inventor], he did not prosecute the ‘454 patent application [Request for Continued Examination] and response that was submitted . . …

It's not just you. Multiple firms in town have been experiencing issues with the Court's PACER system since yesterday. Most parts of the website work fine, and you can still make filings. But one of the most critical part of the site, pulling a list of docket items in a case, appears to be down. Others report that it's still working.

This feature is something I use multiple times per day. When I'm making a request of the Court, I like to check the docket to make sure I have the most up-to-date info about what's going on in the case. I also like to use exactly the same documents thatthe Court sees. Plus, it's helpful …

Typically, final judgment is the end of the road for a patent case. It's right there in the name. Sometimes, however, it is just a further maneuver in a forever war which the parties have little hope of resolving in their lifetimes.

There are, of course, only limited legal avenues for keeping the fires burning after final judgment. Today's case (oddly, the same as yesterday's case) deals with contempt.

As we discussed yesterday, BioDelivery Sciences International, Inc. v. Alvogen Pb Research & Development LLC, C.A. No. 18-1395-CFC-CJB (D. Del.) had proceeded to judgment years ago, with the plaintiff generally prevailing.

Like most ANDA cases, the judgment contained a clause enjoining the defendant from making/selling/using the "ANDA Products" until after the expiration of the infringed patents. D.I. 308.

Years later, the defendant filed a new ANDA based on the same listed drug, apparently reformulated to design around the relevant patents. The Plaintiff, in addition to filing a new ANDA case against this ANDA, brought a motion to enforce the judgment.

Judge Connolly denied the motion, finding that it was procedureally improper:

I need not decide whether the products covered by ANDA No. 220582 are an "ANDA Product" covered by paragraph 7's injunction because I agree that the motion is procedurally improper, and I will deny it for that reason . . .
I agree that to the extent BDSI seeks to enforce the injunction in paragraph 7, it must do so by way of a contempt motion. An injunction is "an equitable decree compelling obedience under the threat of contempt[.]" And thus "injunctions are enforced through the district court's civil contempt power." Accordingly, "[i]f a party contends that another party is violating an injunction, the aggrieved party should move the court for an order to show cause why the other party should not be held in civil contempt."

D.I. 423 at 9-10 (internal citations omitted).

It's not clear from the opinion whether the door is technically open for a further motion for contempt. However, given that the Court took the parties to task for the "waste of judicial resources" and "obstreperous behavior by both sides to a degree I have rarely experienced as a judge" I would not be at all surprised if the plaintiff just let it lie and continued with the new case. Only time shall tell.

Well, this is a new one. Apparently, in BioDelivery Sciences International, Inc. v. Alvogen Pb Research & Development LLC, C.A. No. 18-1395-CFC-CJB (D. Del.), the defendant found out just a little bit too late that their expert had an ethical conflict because he had previously represented the plaintiff.

It's hard to tell exactly what the circumstances were here, because it looks like the relevant motion and all related briefing is fully sealed, with no redacted versions available.

But from what I can see, the plaintiff received a judgment in its favor on some of its claims back in 2022. (D.I. 308). …
