The Mavexar crab is starting to sweat.

It looks like activity is picking up again in the Mavexar cases. If you haven't followed all of our coverage so far (I don't blame you!), here is a summary of where we left off.

Today, Chief Judge Connolly issued an order denying a Mavexar entity's motions to set aside or stay compliance with the Court's March order requiring them to produce various documents, including potentially privileged documents.

He found that Supreme Court precedent shows that the District Court retains jurisdiction regarding collateral issues—like this one—even after a dismissal. According to the Court, that remains true regardless of whether the issues are raised by the parties or by the Court itself (as …

There was an interesting oral order from Judge Burke last week in Natera, Inc. v. CareDX, Inc., C.A. No. 20-38 (D. Del. Apr. 28, 2023). Defendant apparently asserted a large number of § 112 defenses based on lack of enablement or written description. The Court held that the defendant had to narrow it's defenses.

The parties further disputed whether the parties should count § 112 arguments by limitation or by claim. The Court held that they should be counted by claim limitation, not by claim:

With respect to the parties' dispute as to whether an argument that a claim is invalid under section 112 based on a particular claim limitation counts …

The defendants in Corteva Agriscience LLC v. Monsanto Company, C.A. No. 22-1046-GBW (D. Del. Apr. 27, 2023) moved to stay after a third party initiated an ex parte reexamination of the patents-in-suit.

To meet the "simplification" factor in moving to stay, defendants offered to drop their obviousness-type double patenting defense:

The first factor—whether granting the stay will simplify the issues for trial—disfavors a stay. Defendants assert a stay would simplify the case. First, Bayer claims it will agree to not argue that the '555 Patent is invalid for obvious-type double patenting ("OTDP") on the basis of U.S. Patent No. 11,149,283 ("the '238 patent" ) and that dropping this argument will simplify the issues for trial. D.I. 41 at 9.

The Court quickly dispatched with that idea, noting that it was essentially a throw-away argument:

However, Defendants recognize that Corteva can overcome the OTDP argument if Corteva files a terminal disclaimer. 3 Id. at 9-10. Because it is likely that this OTDP argument will not make it to trial anyway, the Court does not find that Bayer's offer to drop the argument will simplify the case.

The Court found that the factors did not favor a stay, especially considering the plaintiff had added two additional patents in the time since defendants filed their motion, and those two patents are not subject to re-examination. Beyond that, a stay would likely preclude injunctive relief (due to a patent expiration).

All told, it's not clear how they could have prevailed on this motion at all after the plaintiff asserted the two additional patents.

I usually don't expect a fight about withdrawing a claim. Adding one? sure. Striking one? Also Sure. Squishing two of them together and pretending they're dancing? Definitely.

Generally though, the voluntary withdrawal of a claim makes life easier for the parties and the Court and passes from the case without comment or concern. That said, you can see why the withdrawal in MirTech, Inc. v. AgroFresh, Inc, C.A. No. 20-1170-RGA (D. Del. Mar. 23, 2023) (Mem. Op.) was more contentious.

The case had been pending for almost two years when Judge Andrews "encouraged the parties to avoid the over-litigation that [he] thought was happening in th[e] case." This "encouragement" took place about a week before the Defendant moved for SJ on several topics. plaintiff filed its opposition brief a month after that.

The defendant then took the unusual step of withdrawing one of the claims it had moved on—nominally without ...

Broken Communication

Parties can freely stipulate to many things in the District of Delaware, and often stipulations to extend deadlines are filed close to the last minute, especially where the parties are working toward agreement but ultimately cannot agree on the final filing in time (or else are having trouble connecting with the other side).

However, stipulations filed close to the Delaware witching hour (5:00PM EST) can be fraught with risk of the Court's denial, as we’ve seen in past heart-stopping examples. We’ve warned before that requests to move Court-scheduled conferences are in the “iffy” category, and combined with last minute filing, can end in disappointment for everyone, as shown in an oral order from Judge Noreika last week in Neurocrine Biosciences, Inc. v. Lupin Limited et al., C.A. 21-1042, D.I. 197 (D. Del. Jul. 16, 2021):

On April 17, 2023, the Court instructed the parties to talk to each other about their disputes so that a follow-up call with the Court (set for April 21, 2023) would be more productive than the prior call. On April 21, 2023, a few hours before the set call, the parties submitted a stipulation requesting the April 21 call be delayed. After further inquiries, it became clear that, in the five days after the Court directed the parties to TALK, they did not do so. The Court intended to address that during the April 21 call, but no counsel appeared for the call (notwithstanding that the Court had not granted the request for a delay). THEREFORE, IT IS HEREBY ORDERED that, should the parties not inform the Court that they have resolved their dispute in full by Tuesday April 25, 2023, lead trial counsel SHALL appear in person in Courtroom 4A on April 26, 2023 at 3:00 p.m. ORDERED by Judge Maryellen Noreika on 4/21/2023.

Judge Noreika previously indicated frustration with the magnitude of this particular discovery dispute (on search methods to find responsive documents), so the parties were on thin ice long before ...

It begins with a series of interminably long emails. I say that you really should be producing these documents—I cite cases, exhaustively describe the items sought, and cite check the whole thing like it's headed to the Supreme Court. You respond by pointing out that I am just hopelessly misguided, and have perhaps been drinking. You also cite cases.

Eventually everyone gets on the phone to hash things out. Two hours later you agree to take my positions "under advisement" and call it a day.

Meet and confer accomplished.

It's not always that bad, but there is definite potential for one or both parties to drag the process out. It's rare to see any consequences to this sort of slow-rolling, as it's usually invisible to the Court.

Every now and then, though, someone gets called out for it, and yesterday was one of those days. The dispute in TwinStrand Biosciences, Inc. v. Guardant Health, Inc., C.A. No. 21-1126-GBW-SRF (D. Del. Apr. 24, 2023) (Oral Order) was your usual request that a party supplement an interrogatory. Judge Fallon granted the motion, but took the unusual step of noting the somewhat tortured history of the parties' correspondence

Guardant's second supplemental response to Interrogatory No. 6 provides some of this information for only one of the Asserted Patents. Guardant represented that it would produce and identify documents responsive to the Interrogatory under Fed. R. Civ. P. 33(d) as discovery continued. Guardant's responses to Plaintiffs' requests for supplementation of Interrogatory No. 6 during the meet and confer process suggest that Guardant may have additional responsive information that has not yet been disclosed. (As of March 17, 2023, Guardant represented it "will provide our position or a supplementation in due course"); (As of April 4, 2023, Guardant was "considering [Plaintiffs'] proposal and hope[s] to have a response soon."). Otherwise, Guardant could have put the matter to rest and avoided burdening the Court by simply confirming that it had no additional information responsive to Interrogatory No. 6.

The phrasing here is not quite a rebuke, but parties generally like to keep their name as far removed from ...

"Did I remember to disclose my infringement counter-arguments? Ah well, I'll just argue that they're responsive." Tim Bogdanov, Unsplash

Judge Williams unsealed a detailed Pennypack decision Friday, where he struck an expert's infringement argument after the party failed to disclose it in their contentions.

The motion and brief provide some helpful context here. The defendant moved to strike material in the expert's opening report that apparently responded for the first time to arguments made in the defendant's non-infringement contentions. Cirba Inc. v. VMWare, Inc., C.A. No. 19-742-GBW, D.I. 1460 at 1 (D. Del. Nov. 28, 2022); Id., D.I. 1461 at 2-3.

The Court rejected an attempt to argue that the argument was "responsive" to a filing …

Words to live by when thinking about whether you need to go to the Court on your nth dispute this week.

It's easy, especially at trial or in the lead-up to trial, to feel like you need to bring every dispute to the Court. The stakes in patent cases tend to be high, clients want to see progress, and sometimes every little dispute ends up feeling critical (particularly if the outcome impacts your trial plans).

Beyond that, sometimes more junior associates are tasked with handling disputes as trial approaches—and may be given the implicit authority to raise disputes, but not to resolve them. Shockingly, disputes can then multiply pretty quickly.

What happens when you start …

Today I noticed for the first time what may be a new move in the redaction game. I neither like nor understand chess (the two may be related), but it feels like I witnessed the birth of the French defense.

As we've discussed ad nauseum, it has become standard practice for Judge Andrews to reject filings that redact exhibits in their entirety (or nearly so) with an oral order like the following:

ORAL ORDER: The redacted filing (D.I. 163 ) is REJECTED because parts of it are redacted in its entirety. Absent a compelling reason, supported by a statement under oath by a party, redactions in their entirety are impermissible; redactions must be done so as to redact the least possible amount of the materials submitted. Failure to make a good faith attempt at such redactions may result in sanctions, the most common of which would be simply unsealing the entire filing. Redacting in its entirety a document or parts of it that contains publicly available materials is prima facie evidence of bad faith. A revised redacted filing is DUE within five business days.

Vertex Pharms. Inc. v. Sun Pharm. Ind. Ltd., C.A. No. 20-988-RGA (D. Del. Apr. 12, 2023).

Despite this repeated refrain, I still see at least a couple such orders every month. This week, however, was the first time I saw a party take the step of submitting "a statement under oath by a party" at the same time it submitted its redactions, rather than waiting for them to first be rejected.

Interestingly, the statement itself was fairly light on detail stating only that it was redacting "the proprietary formulation contained in its ANDA" and describing ...
