Motion to Strike Delay

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.

AI Companies Have a Rough Road Ahead on Copyright Issues

I don't talk about it much on the blog, but my other hobby (beyond writing about litigation and the District of Delaware for funsies, photography, and having an absurd-by-today's-standards number of children) is writing and speaking about AI and the law. I've been speaking about AI issues on panels at conferences since 2018. Most recently, I moderated a Sedona Conference panel about Copyright and AI.

In the context of copyright and AI, the question of whether training an AI model on copyrighted content is fair use is basically life-or-death for a lot of current AI models. Big generative models like ChatGPT are (typically) trained on giant masses of data collected from books, …

Order Of Operations

Bond Preliminary Injunction

If you've spent way too much time on the internet lately, you'll likely have seen way too many memes about how kids today don't understand the order of operations. The typical format is some bookface (tm) post along the lines of:

999,999 out of 1,000,000 people get this wrong:
3 + 4(3+2) - 2 X 3 = ?
  1. 17
  2. The darkness at the end of all time
  3. 97
  4. (audible belch)

And then there's someone confidently giving the wrong answer.

Of course, the correct answer can only be arrived at by following the prescribed order of operations. This same concept comes up quite often in civil procedure, but the application is often less straightforward than good old …

"A Physicist, a Chemist, and an Economist Find Themselves on a Desert Island with a Single Can of Food . . ."

Visiting Judge Wolson of the Eastern District of Pennsylvania issued a colorful opinion on Monday. It starts with a joke:

Economists love assumptions. One joke recites that a physicist, a chemist, and an economist find themselves on a desert island with a single can of food. The physicist offers to calculate the force needed to use a coconut to open the can. The chemist offers to make a solution that will eat through the can’s top. The economist tells them they are making it too complicated and just to assume a can opener.

Read Those "So Ordered" Entries Closely! Court Rejects Stipulation After Warning Parties In PDF Copy of Previous "So Ordered" Stipulation

Andrew E. Russell, Nov. 3, 2023
Stipulation Litigation

In D. Del., stipulated extensions of the schedule are routine and are normally granted, with occasional exceptions. Usually, when the Court grants them, it results in an unremarkable order like this:

Order re Stipulated Extension

There's really nothing there. Occasionally, though, it results in an order like the below. Can you spot the difference?

Order re Stipulated Extension with Attachment

Can you see it? It's tiny. The only difference is that the docket number ("52") is a link. I don't blame you if you missed it.

Usually, clicking on that link, you'll find a plain-Jane stamped or signed version of the stip as filed. Nothing remarkable or meaningful at all. It feels wrong to bill .1 hours to a client to click on the stip and look at …

Judge Bibas gave us this gift of a general interest (comparatively) post with his decision yesterday in Thomson Reuters Enterprise Centre GmbH v. ROSS Intelligence Inc., C.A. No. 20-613-SB (D. Del. Sept. 25, 2023) (Mem. Op.).

The case deals with the exceptionally buzzy issue of AI data scrubbing. Thompson Reuters runs the hugely popular Westlaw legal research platform. As part of that service they provide they provide vaguely useful "headnotes" describing the holdings of the cases.

(Eds. Note - Westlaw, if you are reading this, we can be bought. Every 10% you discount our service will result in an improvement of the adjective above. We can go all the way from "vaguely", to "quite", to "masterfully." It's about time this blog started paying the bills).

Judge Bibas Notes Delaware Split Regarding Unclean Hands Counterclaims in Patent Cases

MTD Motion to Dismiss

In an opinion on Friday, visiting Judge Stephanos Bibas of the Third Circuit pointed out a split in District of Delaware cases regarding whether a party can bring unclean hands counterclaims in patent cases:

Nor does TexasLDPC persuade me this declaratory-judgment counterclaim fails as a matter of law. True, courts disagree whether “unclean hands” can support a declaration that a patent is unenforceable. Compare In re Gabapentin Patent Litig., 649 F. Supp. 2d 340, 348 (D.N.J. 2009) (concluding it cannot), and Kimberly-Clark Worldwide, Inc. v. Cardinal Health 200, LLC, 2012 U.S. Dist. LEXIS 104983, at *2–3 (D. Del. Jul. 27, 2012) (same),[ ]with The Meds. Co. v. Teva Parenteral Meds., Inc., 2011 WL 13141923, at *1 n.2 (D. Del. Oct. 6, 2011) (denying motion to dismiss or strike unclean hands counterclaim).

Judge Bibas sided with the cases holding that "unclean hands" is a proper counterclaim in a patent action:

Still, I will not stop Defendants from demanding a declaratory judgment about the unclean-hands doctrine. In my view, I may grant such relief. See Qualcomm Inc. v. Broadcom Corp., 548 F.3d 1004, 1025–26 (Fed. Cir. 2008) (“[A] district court ...

Judge Bibas: "Equivalent" Doesn't Imply "Bioequivalent"

Drugs

Sitting by designation in D. Del., Circuit Judge Bibas recently issued an interesting 12(b)(6) opinion on false-advertising claims in the pharma context. These opinions tend to fly under the radar, but they often contain helpful practice tips.

The parties "both sell a medical cream, each with the same active ingredients in the same strength." Although the defendant's cream "is not an FDA-approved generic and has not been tested for bioequivalence[,]" it was listed in a database of pharmaceutical products "as an 'Equivalent Drug[.]'"

Judge Bibas found that this statement was neither false nor misleading:

Yet Sebela insists that “equivalent” implies more: bioequivalence and FDA approval. . . . The FDA has not approved TruPharma’s cream. But …

Judge Bibas: "Deadlines are not suggestions. Litigants must respect them."

Substantial Completion FRCP 26

As we've discussed, parties sometimes treat the deadline for "substantial completion of document production" as a soft deadline, doing a "rolling production" afterwards that can be quite voluminous. An opinion from Judge Bibas today shows the risk of not taking that deadline seriously.

In the opinion, Judge Bibas excluded over 60,000 rows of spreadsheet sales data that were produced by a defendant in an Fair Labor Standards Act class action, after the defendant waited until six months after the deadline for substantial completion of document production to produce the data.

As usual for Judge Bibas, his opinion is an interesting read and a bit different from what we typically see from other judges in Delaware. …

As we mentioned in our last post, Judge Bibas of the Third Circuit has taken two D. Del. patent cases by designation, along with a number of other cases.

I've seen a number of his opinions in other cases come through over the course of the year. They are easy to identify, as his writing style differs from any other judge we've had, in a way that is interesting to see.

One particularly notable opinion of his issued back in March, and apparently slipped our notice at the time. In it, he denies an FRCP 12(b)(6) motion, holding that a defendant's own patents can serve as circumstantial evidence that its products practice the claims, if those patents describe an infringing configuration. ...
