A Bifurcated Apple

Earlier this year Judge Hall bifurcated the upcoming patent trial in Apple Inc. v. Masimo Corporation, C.A. No. 22-1377-JLH (D. Del.), keeping Apple's patent claims, the related invalidity and unenforceability defenses, and a portion of a Walker Process anti-trust counterclaim—but moving other claims to a later trial:

ORAL ORDER: Having held a case management conference on March 20, 2024, . . . IT IS HEREBY ORDERED that a 5-day jury trial is scheduled beginning October 21, 2024, with a pretrial conference scheduled for October 4, 2024 at 11:00 AM in courtroom 6D. The remaining claims and defenses in C.A. No. 22-1377 and C.A. No. 22-1378 shall be joined and/or bifurcated for trial such …

Best wishes and get well soon.

Visiting Judge Murphy decided a stay motion in a patent action yesterday, and included language that could be helpful to any patent plaintiffs who are opposing an early stay.

In Ignite Enterprise Software Solutions, LLC v. NGData, US Inc., C.A. No. 23-1209 (D. Del.), the defendant moved for a 30-day stay after its lead counsel suffered a head injury in a car accident.

The Court moved shockingly fast (for a busy Court), requesting that the plaintiff respond within two days, and then ruling on the motion the same day the plaintiff responded—just two days after the initial paper.

The Court denied the stay due to prejudice to the patentee:

Defendant seeks a 30-day …

True D. Del. patent litigators know that, no matter which side you're on, you're going to have to narrow your claims and defenses before trial. It's just unwise and unworkable to go into a five-day trial with 100 claims, or with 30 prior art references and hundreds (or millions) of potential obviousness combinations. There isn't time to cover it all.

That said, sometimes the parties in patent cases delay case narrowing for a long time. And while the Court will often narrowing, it doesn't do that in every case. Instead, judges sometimes take the approach that …

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.
  • Swirlate (the NPE) and its …

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.

Narrowing
AI-Generated, displayed with permission

A perennial question in disputes about late disclosures is whether the demanding FRCP 16 "good cause" standard applies, which hinges on diligence, or whether the more forgiving Pennypack 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 multiple times 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.

In State Farm Mutual Automobile v. Amazon.com, Inc., C.A. No. 22-1447-CJB (D. Del.), the Court ordered the defendant to cut …

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 …

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 …

I hope the Third Circuit one day revisits the Pennypack factors, which are what it directs the lower courts to apply to determine whether late disclosures are subject to sanctions such as preclusion.

The factors can be lenient on parties that are very late in disclosing critical facts. Pennypack sets up a system where, oddly, the more critical the late-disclosed fact is, the later the party can be, and the less likely it is to be excluded. Isn't that backwards?

In practice, the factors often seem to turn on whether there is incurable prejudice, and that can be hard to establish. But a rule that "you …
