Chief Judge Connolly held a second Mavexar-related hearing yesterday, this time in Swirlate IP LLC v. Quantela, Inc., C.A. No. 22-235-CFC (D. Del.). This was after the one in the Backertop action that we just posted about.
Chief Judge Connolly questioned both the out-of-town attorney who represented Swirlate as lead counsel in the action, and the sole member of the Swirlate NPE
The Court addressed several topics with the attorney, including:
Gaps and redactions in the court-ordered document production, which was supposed to include communications with his client.

Judge Andrews issued a lengthy summary judgment and Daubert opinion on Thurday in Acceleration Bay, LLC v. Amazon Web Services, Inc., C.A. No. 22-904-RGA (D. Del.). The opinion hits multiple interesting issues, and we may have a couple of posts on it this week.
But the one ruling that jumped out to me was the Court's rejection of the fairly typical, low-effort motivation-to-combine language that many experts rely on in their obviousness opinions.
Motivation to combine is often an afterthought. I've seen many initial contentions that address it only in a short paragraph that basically just lists characteristics of each reference (same field, same problem, etc.). Expert reports sometimes uncritically adopt paragraphs like that no elaboration.
If you've ever been involved in reading or writing invalidity contentions, you've probably seen motivation-to-combine paragraphs just like this one, from Thursday's opinion:
As those charts show, [the first reference] ATT Maxemchuk builds upon [the second reference] ’882 Maxemchuk and informs a POSITA of additional details related to ’882 Maxemchuk’s grid-based mesh network. A POSITA would be motivated to combine these references for several reasons. Both references are in the network architecture field and are directed to improving mesh networks. Both teach the simplification of routing of data that arises from the grid-based mesh network. And both disclose the same grid-based mesh network. In addition, ATT Maxemchuk includes additional implementation details for the grid-based mesh network that ’882 Maxemchuk describes.
The paragraph gives just four one-sentence reasons for its statement that a person of skill in the art would combine the references. Three of the reasons are about general similarities between the references.
The fourth sentence is a bit more helpful, and says that the first reference provides "additional implementation details" for part of the second reference.
The Court found that this paragraph—which the parties agreed was representative—simply could not provide support for a motivation to combine the references. The Court granted summary judgment of no obviousness:
Mr. Greene “fails to explain why a person of ordinary skill in the art would have combined elements from specific references in the way the claimed invention does.” . . . His opinion does nothing more than explain why the prior art references are analogous to each other and to the claimed invention. . . . Plaintiff’s “assertions that the references were analogous art, . . . without more, is an insufficient articulation for motivation to combine.” . . .
As Defendant’s invalidity contentions rely on Mr. Greene’s testimony, Mr. Greene’s failure to opine on a POSA’s motivation to combine the asserted prior art references proves fatal to Defendant’s obviousness theory. I grant summary judgment of nonobviousness as to all asserted obviousness defenses.
Acceleration Bay, LLC v. Amazon Web Services, Inc., C.A. No. 22-904-RGA, at 37-38 (D. Del. Sept. 12, 2024).
A perennial question in disputes about late disclosures is whether the demandingFRCP 16 "good cause" standard applies, which hinges on diligence, or whether the more forgivingPennypack factors apply.
When it comes to case narrowing, there seems to be a building trend that the good cause standard applies, not the Pennypack factors. We've seen that multipletimes when it comes to a plaintiff's decision to drop claims, and on Wednesday, Judge Burke issued a detailed opinion finding that good cause is likewise required to revise a defendant's election of prior art references.

Last week, Nate wrote a post titled "Demonstrative Lost" about an instance where the Court rejected the parties' attempt to lodge demonstrative exhibits used at trial in the record.
In response, we heard from a reader about an upcoming and brand-new rule of evidence, FRE 107, that may address exactly this point, plus some other issues regarding demonstratives at trial.

Yesterday, the Court dismissed a case where the plaintiff failed to list a related case involving one of the same patents in the civil cover sheet (one of several documents required for a new case). Witricity Corp. v. Ideanomics, Inc., C.A. No. 24-895-JLH, D.I. 15 (D. Del. Aug. 22, 2024).
The first case was assigned to visiting Judge Goldberg, who had stayed it. When the plaintiff filed the second case, it did not list the first case in the cover sheet, and the Court randomly assigned the second case to Judge Hall.
The defendant in the second case smartly informed the Court of the issue by filing a short "Notice Regarding Related Case" …

Our blog readership remains pretty high these days, and we continue to grow subscribers. But not all District of Delaware attorneys follow the blog—yet.
That may be why, even though we've talkedabouttheseatlength, parties continue to file separate "concise statements of material fact" in support of their summary judgment motions that list non-material facts and do not include pinpoint citations—potentially resulting in denial of their motion.
Here are some guidelines for when you are putting together a concise statement of material facts in support of an SJ motion:
Include only the material facts. If you could still win your motion if a fact …

This is another one where I saw a potentially useful order about an issue that comes up from time to time, and thought "I should write a blog post about that, so I can find it later." I hope this will be helpful for others as well.
Last week in Nexus Pharmaceuticals, Inc. v. Exela Pharma Sciences, LLC, C.A. No. 22-1233-GBW (D. Del.), the Court addressed the question of whether a plaintiff in a "competitor-competitor" patent case could compel production of the defendant's corporate-level financials. It held that no, it could not, …
The Court often limits parties to a total of 10 terms for construction. But sometimes it seems like, under O2 Micro, a party can't really waive a claim construction position. After all, if there is a dispute, the Court will have to construe the term one way or another, right? It can't go to the jury like that?
We got a clear answer to that question on Friday when Judge Williams held that both parties had waived their right to offer certain constructions, which they offered just three days before trial.
The parties asked to construe a total of five terms. The Court held that it was within its discretion to …
It's hornbook law that demonstratives are not evidence. Nevertheless, you'll sometimes see parties file some or all of them on the docket, if for no other reason than to explain a portion of the transcript where an expert is otherwise gesturing vaguely at a powerpoint.

Unfortunately, there's no rule squarely addressing when it is appropriate to lodge these demonstratives with the Court. Fortunately, Judge Hall gave us all a bit of guidance last week in Ferring Pharms. Inc. v. Finch Therapeutics Group, Inc., C.A. No. 21-1694-JLH, D.I. 494 (D. Del. Aug. 28, 2024).
In that case, both parties filed their trial demonstrative a few weeks after the verdict (via notices of lodging). Just …

There is a lot of precedent in D. Del. regarding when the parties can and can't present evidence from post-grant patent proceedings such as IPRs. Most often, the Court holds that such evidence is inadmissible or constrained, to prevent it from unduly influencing the jury. "We already won this once" can be a powerful argument.
Last week, Judge Williams issued an opinion taking the usual position as to most evidence. But the Court also held that simply asserting a prior art reference that was raised in post-grant proceedings opens the door for the patentee to introduce …
