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:
ne of my many litigation dreams is to develop an inescapable trap for my opponent. A no-win situation in which to prevail on infringement, they must lost validity or vice versa. In Insoluble dilemma that can only lead to their resigning the case.

On this note, I present to you the novel indefiniteness theory presented in Kaneka Corp. v. Designs for Health, Inc., C.A. No. 21-209-WCB (D. Del. June 16, 2025). The claims at issue there were your garden variety claims to a solution that specified at least X% of unobtanium, Y% of salt, etc. The claims did not specify the precise parameters under which one was to measure these percentages.
(Eds. Note—Always fun to see some analytical chem in an opinion. Shout out to my HPLC and HPLC-MS peeps, ride on)
The defendants' expert had apparently measured the percentages of their product using his preferred method, and found that it was outside of the claimed percentages. The defendants then made the unusual move of submitting a conditional expert report on indefiniteness, arguing that if the plaintiff's expert found that the product did infringe, it meant the claims were indefinite because different methods for analyzing the percentages could yield different results, and thus that a POSA would not know whether a given product infringed.
Judge Bryson rejected this theory, and granted a motion to strike the report:
The defendants’ theory of indefiniteness is that if different testing methodologies produce different results, such that one testing protocol shows infringement and another shows no infringement, the claim language at issue must be indefinite. That theory is fundamentally flawed. As long as the claim defines infringement according to a single measurable standard, the fact that two different testing protocols may produce different results creates only an issue of infringement. It does not create an issue of claim indefiniteness.
In such a case, if two measurement techniques produce different results—one infringing and the other not—the task of the litigants and the fact-finder is to determine which of the two techniques is the more accurate, and to base a judgment of infringement on that finding. In this case, the limitation at issue requires Kaneka to prove that “the proportion of reduced coenzyme Q10 relative to the total amount of coenzyme Q10 is not less than 90 wt %.” That is a fixed ratio with a single value for a specific chemical compound. Different testing methods, or testing done at different times and under different conditions, may produce varying results, either above or below the 90 wt % figure. But that is just to say that different testing procedures may be more or less accurate, and that particular samples of the accused product may infringe or not infringe depending on the conditions under which they are tested. But inconsistency in the results does not indicate that the claim limitation is indefinite, as 90 wt % of reduced coenzyme Q10 has only a single meaning, even though different tests at different times and under different conditions may produce results on either side of the 90 wt % value, which is fixed and definite.

I will speak a truth that many of you have suspected. Sometimes we (well, I) pick a case just because it has a fun name. My original post today was about HQ Specialty Pharma Corp. v. Fresenius Kabi USA, LLC, C.A. No. 21-1714-MN. Honestly the case was too fact intensive to easily convert to a general interest blog post. On the other hand, it contained a great deal of discussion of the testimony of a New Jersey Pharmaceutical executive named Mr. Pizza.

Deadline extensions are perhaps the most common of all requests to the Court. I have seen requests granted for medical reasons, conflicts with deadlines in other cases, prescheduled vacations, and the need to enact a dark ritual which can only take place when the moon fears to rise (we'll have a post about that one on the future, assuming the ritual is unsuccessful and does not result in all things returning to dust beneath the sacred ash and the profane oak).
Today's post, however, is a tale of an extension denied. The defendant in Purdue Pharma LP v. Accord Healthcare Inc., C.A. No. 22-913-WCB, D.I. 111 (D. Del. Oct. 2, 2024) had prevailed on its obviousness defense following a bench trial and filed a timely motion for fees 14 days after the Court entered final judgment.
The plaintiff, however, apparently intended to appeal the invalidity determination and thus requested that the defendant stipulated to defer briefing on fees until after the resolution of that appeal. When the defendant refused to stipulation, plaintiff moved to defer briefing until after the appeal and requesting expedited consideration of the motion (as the clock was already ticking on its 2-weeks to file a responsive fees brief).
Unlike in the true to life examples listed at the start of the blog, the plaintiffs motion was not based in any particular conflict with client or counsel. Instead, the deferment was based on the general proposition that "the appeal may impact or otherwise refute the bases for Accord’s motion." Id., D.I. 108 at 2. The defendant filed a short opposition to the motion, noting that this logic would apply to essentially any motion for fees.
Judge Bryson denied the motion to defer the briefing in a short order:
The motion to defer briefing on Accord's motion for attorneys fees 108 is denied. The court will determine when to rule on Accord's motion for attorneys fees after the briefing is complete.
We'll keep a watch out for that fees opinion and let you know if it comes before or after the appeal.
Motions to stay are common as dirt, and about as interesting.
The factors are exactly what you expect them to be, and the Court has broad discretion to apply them. Most of these motions could be reduced to a checklist:
I want you to take a deep breath and imagine yourself in the heady days of 2015. Every night you enjoy the newly released Doritos' loco taco. Every morning you practice the harlem shake. Game of Thrones has so much promise. Life is good.

For the patent litigator (e.g., everyone reading this), the law is in an interesting place. Form 18 is about to be abolished, and there is a great deal of of hemming and hawing about how much detail will need to be included in a complaint for patent infringement. Yours truly even jumped on the hype train and wrote an article on it for Landslide (other than the Alice Cooper reference in the title, which I think went largely unnoticed, it bears little resemblance to the current blog).
For defendants, things were trickier still. The question of what level of detail was required for pleading the usual counterclaims of noninfringement and invalidity was even more up in the air. Several Delaware decisions even held that greater particularity was required for counterclaims than infringement claims. For instance, Judge Robinson made the following statement in dismissing invalidity counterclaims in Senju Pharm. Co. v. Apotex, Inc., 921 F. Supp. 2d 297, 302 (D. Del. 2013):
the fact that Form 18 (rather than Twombly and Iqbal) remains the standard for pleading infringement claims is an insufficient justification for deviating from Twombly and Iqbal for pleading other causes of action . . . Therefore, the court concludes that the pleading standards set forth in Twombly and Iqbal apply to counterclaims of invalidity.

Yesterday Nate wrote about Judge Bryson's opinion that a plaintiff was not bound by its prior allegation that a product infringed two claims, because plaintiff's statement deals with an issue of law, not fact.
Today, I think it's worth discussing another aspect of the same decision, where Judge Bryson addressed a motion by plaintiff to preclude the defendant from discussing the same two invalid claims, claims 9 & 9 of the two asserted patents.
The the PTAB canceled claims 9 and 9 in an IPR, and plaintiff now asserts only claims that depend on those two canceled claims. It moved to prevent defendant from …
Lawyers are famously careful. We double-knot our shoes. We check the expiration date on milk, cheese, and even BACOS-brand non-bacon chunks. More than anything, we are famous for hemming and hawing and avoiding a direct response to seemingly simple questions in a transparent attempt to avoid saying something that might later be used against us.
This is a tale of one such admission that turned out alright.
So maybe don't worry so much.

The initial complaint in Prolitec Inc. v. ScentAir Technologies, LLC, C.A. No. 20-984-WCB (D. Del. Jan. 12, 2024) (Mem. Op.) stated pretty baldly that the defendant infringed claim 9 of the patents-in-suit.
(Eds. note, for no sensible reason it was claim 9 of both patents. I spent about 15 minutes trying to figure out how best to parse that grammatically, briefly toying with "claims 9," like "attorneys general" before realizing I don't get paid for this and giving up).
There were claim charts and everything.
This is normally what you want in a complaint, really. You kind of have to accuse them of infringement after all. The difficulty is that claims the ninth (?) were both invalidated at IPR and so the plaintiff was left to assert various dependent claims. They amended the complaint accordingly, removing any reference to the now-cancelled niners (?).
When it came to trial, defendant wanted to use the earlier complaint as evidence that their own products practiced all but the few extra limitations of the dependent claims, thus bolstering their invalidity and damages cases.
Plaintiff argued that the original complaint could not be used against it because it had been superseded (I sometimes see this called "rendered a nullity" which I quite like) by the amended complaint. Accordingly, they moved in limine to prevent those statements from being used against them at trial.

Judge Bryson issued an opinion today in Michael R. Cahill, Trustee of the Hunt Irrevocable Trust v. Air Medical Group Holdings, Inc., C.A. No. 21-679-WCB (D. Del. Oct. 16, 2023). In it, he describes a clever procedural maneuver that failed, but resulted in a positive outcome anyway.
The case involves an breach of contract claim affirmative claim and counter-claim. The Court granted summary judgment for the plaintiff on their affirmative claim, holding that it was time-barred under a provision of the contract that set out a time for bringing claims.
