"Did I forget to say why we should win the motion?"AI-Generated, displayed with permission
When you're drafting a brief, it can easy to get bogged down in all of the in-the-weeds counter-arguments and surrounding issues, and to kind of forget about the main point you need to make.
Years ago, in a patent case, I wound up needing to write three initial drafts of three summary judgment briefs in a week. Fun, right? The first two came together OK. The third one, not so much. It was a complicated motion involving many potential counter-arguments.
I remember thinking the initial draft was pretty good when I clicked send on the e-mail attaching it. How could it not be? In just …
Anyone who's been a lawyer long enough to read blogs about will have purchased some custom-made legal accessories. A monogrammed briefcase is a classic, as are cuff links and (for the daring) a bolo tie. The especially theatrical amongst you might get a cape, walking stick or dark altar. The important thing is that it fits, and is monogrammed.
I wasn't sold on the dark altar, but it actually came with a monogrammed cape, so...AI-Generated, displayed with permission
This of course, naturally leads me to contributory infringement and especially whether a product is "especially made or adapted for use" in an infringing process and not "suitable for substantial non-infringing use."
This analysis is often factually intense, but it doesn't …
Whew! The 2025 District of Delaware Bench and Bar conference wrapped up on Friday (has it really been twoyears!?). It was a wonderful event, as always, and the organizers did an amazing job. All of the panels were great, but I particularly enjoyed Judge Andrews' incredible interview of Judge Bryson (and I heard the same from others).
The conference was especially fun for me this year, because I received a lot of in-person feedback about this blog. Thank you all!! One request was to keep our posts short, and I'll try to do that today.
For anyone who missed it, here are some notes from the conference, organized loosely by topic:

Last year we had a post entitled "Use This One Simple Trick to Not Get Your Summary Judgment Motion Instantly Denied." That post related to motions before judges who require a concise statement of facts with summary judgment motions. The "one simple trick" was that, rather than including a long list of atomic facts like "x said this at deposition" and "lines x:xx - y:yy of the patent specification say z," you state the actual material fact that you are relying on and cite those atomic facts as support for the broader fact.
As a man of letters, I am often astounded by the power of certain small and simple expressions to remain in the general consciousness for decades.
Why does taco Tuesday still ring so true? Any number of callow admen must have attempted to start Fish Friday (a natural choice for many reasons), macaroni Monday, or Waldorf Salad Wednesday, yet all of these efforts are long forgotten.
Will any of us recognize the next great cultural alliteration when it arrives, or will it be known only in history's telling?
In the District of Delaware, Daubert motions (i.e., motions to exclude expert testimony under FRE 702) are normally due at the same time as case dispositive motions, and often share a page limit.
This makes a lot of sense, since Daubert motions are often more or less dispositive of central substantive issues in the case. Sometimes, if the party cannot present expert testimony on a particular substantive issue, they essentially just lose (although for other things, not so much).
Often, parties will present their primary Daubert issues at the deadline, only to realize later on that there are other lingering issues that fit the Rule 702 case law. …
How many attorneys would have made the choice to re-assert § 101 at trial after conclusively losing on that issue at the MTD stage? Not many, I'm guessing.Oliver Roos, Unsplash
I still remember when, as a first-year associate (circa 2009), a senior attorney explained to me that courts will not hold a patent "valid," and instead will normally only say that it is "not invalid." It seemed like a bit of a silly distinction at the time, but it actually makes perfect sense, and it has come up again and again in my practice since then.
Courts do not typically hold that a patent is "valid" because that would suggest it is impervious to future challenges. Instead, courts often hold that a patent is "not invalid," i.e., that the moving party in a case before the Court failed to show that the patent was invalid due to some circumstance. That language recognizes that another party on another day might yet prove the opposite: that the patent is invalid.
This came up recently in Laboratory Corporation of America Holdings v. Natera, Inc., C.A. No. 21-669-GBW (D. Del.). In that case, the defendant had originally brought a motion to dismiss on § 101 grounds, and Judge Stark denied it. Id., D.I. 28 at 7.
Now, almost four years later and in the lead-up to trial, the plaintiff moved in limine to preclude the defendant from re-raising its failed § 101 argument:
Plaintiff "seeks to preclude Natera from presenting argument or evidence regarding patent eligibility of the Asserted Patents under § 101." . . . Plaintiff contends that such preclusion is warranted because (purportedly) "[t]he Court has already spoken on patent eligibility and has ruled that the Asserted Patents are directed to eligible subject matter."
Id., D.I. 325 at 4.
The Court denied the motion, and will permit the defendant to re-raise its § 101 argument at trial. The Court offered ...

Hello again dear friends and readers. In the time the blog has been on hiatus I have built a fence 20 feet high and 20 feet long, gained 400 ELO in chess, and seen many old friends for the first time in ages. But the blog is back, and those days are behind me as I feed more content into its insatiable maw. So let's get right into today's case.
You'll all be aware that a couple of our judges require litigants to rank their summary judgment motions. For instance, and relevant to today's case. Judge Williams' form scheduling order states that "The Court will review the party’s summary …
Figure 2A -- the figure at issue.U.S. Patent No. 11,012,647
This is an issue I don't recall having seen before. In VTT Technical Research Centre of Finland Ltd. v. Teledyne Flir, LLC, C.A. No. 25-348 (D. Del.), the plaintiff filed a pretty typical-looking patent complaint, where it alleged infringement of its patent by the defendant's products.
The complaint, however, relied on an allegation that the product was marked as practicing a particular patent, and that figure 2A of that patent showed a circuit that infringed on the plaintiff's patent:
According to VTT, the figure (“Figure 2A”) [of the defendant's own patent] depicts the allegedly infringing functionality. . . . In the complaint, VTT alleges on information …
Aaaand we're back! We extended the blog break a bit because I was traveling last week to participate on a panel about AI-related litigation at the Sedona Conference. There have been several interesting AI-related copyright decisions this year (including in Delaware), and we may post about them down the line.
For now, I wanted to alert everyone that Judge Burke posted a set of "Tips Regarding Markman Briefing and Hearings" on his website.
The document has 10 total tips, all directed towards Markman practice before Judge Burke. But I would say that it is definitely worthwhile reading for any Delaware litigator. The tips include guidance regarding (spoiler alert):
The number of terms Judge Burke will hear and decide …
