Paper

When it comes to summary judgment and Daubert motions, the local rules here in D. Del. set a limit for the number of pages, but don't set a limit for the number of motions. Our judges' form scheduling orders for patent actions address this, and set length limits for brifing dispositive motions (and sometimes for combined SJ/Daubert briefing).

Sometimes, however, parties end up with scheduling orders that place no limits on the number of motions. In that case, in theory, a party can file as many SJ motions as it wants under the rules, with 20 pages for each motion. In practice, that may not pan out so well.

We saw …

Back in 2021, Chief Judge Connolly instituted a new ranking procedure for summary judgment motions in his cases, in which parties rank their SJ motions and, if the top-ranked motion is denied, all lower-ranked motions are denied as well. The Court later expanded that procedure to encompass Daubert motions as well. Judge Williams has adopted it (for SJ motions only), and Judge Noreika has experimented with it—although at least one other judge has declined to adopt it.

To put the procedures in context, judges on the Court have long applied various measures to control the workload generated by summary judgment motions. Former Chief Judge Sleet, for example, required parties to request leave before filing summary judgment …

Earlier this month we talked about the required structure for briefs in the District of Delaware. As to the required "argument" section, I said "We all know what this is." Maybe I was wrong.

An "Argument" Section That Wasn't

On Friday, the Court denied a motion for summary judgment for violating the local rule on briefing structure, because it's "argument" section failed to conform to the local rule on briefing structure, LR 7.1.3(c)(1)(f), and had exceeded the page limits for briefing. Roger P. Jackson, M.D. v. NuVasive, Inc., C.A. No. 21-53-RGA, D.I. 443 (D. Del. Mar. 14, 2025).

Basically, the patentee moved for summary judgment of infringement. But, rather than laying …

Hole in One

Looks like someone got a hole in one. On Friday, Judge Hall issued a relatively short memorandum order granting a § 101 summary judgment motion, and it neatly encapsulates what § 101 analyses seem to be trending towards.

The Court found that the 10 asserted claims, across three patents, are all directed to a simple abstract idea:

I agree with Netflix that each and every one of the asserted claims is directed to “the abstract idea of collecting, organizing, and automatically displaying content (e.g., a playlist of Internet content).” . . . The asserted claims contain a lot of words, and some of those words sound complicated.[] But what the claims cover is not complicated. …

Proof I have other hobbies

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, …

All of the Delaware judges have rules in their form scheduling orders limiting the circumstances in which summary judgment motions can be filed. Most notably, each forbids the filing of summary judgment motions in ANDA cases absent leave. In other patent cases, SJ motions cannot be filed more than 10 days before the deadline for dispositive motions without leave.

As part of my ongoing series of posts about analytics when I have nothing else to write about (why can't I find Al Capone's cave?), I've compiled some statistics on how likely these motions are to be granted, based on the issue (infringement, validity, something weird).

Looking at all the cases for the last three years (and a bit extra so I could get to 20 and not have to do math) the general success rates for these is a pretty abysmal 20%. Validity issues fair a bit better at about 29%. Infringement/noninfringement also beat the average at about 25%. Weirdly, inequitable conduct seems to fair the worst, at a whopping 0.0% (rounding up).

I've got some more analytics on specific judges, but I'm saving them in case I need another one of these on Thursday.

Both Chief Judge Connolly and Judge Williams require parties to rank their summary judgment motions. This is an effort to deter meritless summary judgment motions. Upon denying a higher-ranked motion, the Court will automatically deny lower-ranked motions as well.

In other words: You had better be careful when ranking your summary judgment motions. But it can be tricky! Do you put the one with the highest chance of success first, even if it's on an issue you don't care as much about? Or do you rank the tougher SJ motion first because it addresses a critical issue first, to ensure that the Court will at least address it?

And what if a motion is granted, but …

Reservation of Rights
AI-Generated, displayed with permission

We don't often write about claim construction opinions, because they can be very fact-specific. But Judge Hall's opinion yesterday in Apple Inc. v. Masimo Corporation, C.A. No. 22-1377-JLH (D. Del.) included some generally applicable points worth noting.

Sometimes a Reservation of Rights Actually Works

There's a reason we've all seen countless discovery documents, disclosures, expert reports, and briefs that are larded up with endless reservations of rights: sometimes they work!

This is one of those times. The patentee (Apple) had filed a response to invalidity contentions regarding a design patent in an IPR. In it, Apple described the scope of its patent, but included a reservation stating that it wasn't taking claim …

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 …

Lightning Strike

Sometimes summary judgment motions or responses end up involving arguments that material should be struck or not considered by the Court. A common question is whether, in making that kind of argument, a party needs to bring a separate motion, or if they can just make it as part of their summary judgment briefing—in an (ugh) footnote, for example.

The answer varies by judge. But we got some guidance from Judge Andrews in his Acceleration Bay opinion last week (which we also wrote about yesterday).

The opinion addressed a motion for summary judgment barring the plaintif from asserting the claims based on a prior contract that contained a non-assertion clause. The plaintiff responded by citing …
