Chief Judge Connolly issued a short opinion this morning denying a motion for summary judgment that a patent was not patent ineligible, in C.R. Bard, Inc. v. Angiodynamics, Inc., C.A. No. 20-1544-CFC-SRF (D. Del. Jan. 3, 2024).
In short, the patentee had previously succeeded on the issue of § 101 ineligibility at the Federal Circuit, which reversed a lower-court finding of ineligibility and held that:
[T]he asserted claims in Bard’s three patents are directed to eligible subject matter under § 101.

The District of Delaware's Default Standard for Discovery requires contentions in patent cases.
One common Delaware counsel question is: what level of detail is required for contentions?
The answer varies on what the concern is. There is a certain level of detail that will probably preclude the Court from ordering you to supplement your contentions—but providing just that bare level of detail may not be enough to preserve all arguments that you later want to make.
On Monday, Judge Burke denied a motion to strike invalidity contentions where a party had disclosed an obviousness theory as to a patent based on modification of a prior art reference, but had not disclosed their intent to cite and rely on their own product as evidence that the modification was obvious.
The plaintiff had moved to strike the discussion of the defendants' own product from their expert reports, on the theory that their contentions failed to to disclose their intent to use that product in their obviousness analysis. Judge Burke denied the motion, and explained that a party need not disclose all evidence in support of its contentions:
Although this is a difficult issue, the Court is not prepared to say that Defendants' actions amounted to an untimely disclosure. This is because Defendants have affirmatively represented that they are not relying on the direct aortic Engager system as prior art itself; instead, they rely on it only as a piece of evidence that will be used to "show that a direct aortic version would have been an obvious modification to Engager 3.0 at the relevant time." (D.I. 361 at 2) In other words, Defendants are relying on the system simply as evidence in support of a theory that was itself timely disclosed. And as Defendants note, courts generally hold that: (a) in validity-related or infringement-related contentions, a party is not required to cite to every piece of evidence that will be used to support a given theory; and (b) it is proper for an expert to expand upon such theories in his expert report. . . . The Court also notes that it is not as if Plaintiff had zero prior knowledge of the existence of the [Defendants'] system. As Defendants point out, they produced documents in discovery regarding this system, and their engineers testified at some length about the device during depositions. . . . (4) In light of the above, the Court cannot say that Defendants' conduct amounts to untimely disclosure that should be stricken.
Speyside Medical, LLC v. Medtronic CoreValve LLC, C.A. No. 20-361, D.I. 447 (D. Del. Dec. 18, 2023).
In my view, the Court is not saying that no evidence at all needs to be disclosed in support of the contentions—just that this particular evidence went beyond what was necessary, under the facts of the case.

The District of Delaware generally suspended its mediation program in 2021, and mediations before a magistrate judge rarely happen in patent cases these days (although they do sometimes happen in some other cases, such as employment cases).
Since then, parties have sometimes moved to private mediations—especially when ordered to—but generally in my experience the overall number of cases that go through mediation has declined, and there aren't a huge number of local patent-case mediators.
When we last discussed this, we noted from comments at the 2023 Bench and Bar conference that …
Chief Judge Connolly's scheduling order requires parties to rank their Daubert motions, and gives the Court the discretion to automatically deny all lower-ranked motions if it denies any one motion. In other words, if a party files five Daubert motions, and the Court grants the first-ranked motion but denies the second, the Court can then deny motions three, four, and five:
If the Court decides to deny a motion filed by the party, barring exceptional reasons determined sua sponte by the Court, the Court will not review any further Daubert motions filed by the party.
It has a similar provision for summary judgment motions Thus, it's important that parties split up their motions and rank them. …

Last month, Judge Williams granted a permanent injunction in Natera Inc. v. ArcherDX, Inc., C.A. No. 20-125-GBW (D. Del. Nov. 21, 2023). The Court unsealed the opinion on Friday, and I thought there were enough interesting things about it to warrant a short post.
The Court granted the injunction only in part, and permitted the defendant to continue using the personalized cancer monitoring product, referred to as "PCM," for "ongoing clinical trials, for updating old studies undergoing peer review, and for limited quality control." The parties also agreed that the injunction should exclude use …
"Here is our argument. The rest of the pieces are in our concise statement of facts."T.J. Breshears, Unsplash
Years ago, I wrote a really terrible first draft of a summary judgment brief arguing invalidity of a patent for obviousness.
I wrote it immediately after expert reports, and my draft failed to actually say why the claims were obvious. Instead, the whole draft read like a sur-rebuttal to the patentee's expert: here is why their first argument doesn't work, here is why their second argument doesn't work, and so on. Never "here is why the claims are obvious."
To me, at the time, it looked great. I rebutted all of their arguments! How can we lose! To others, it …
In AlterWAN, Inc. v. Amazon.com, Inc., C.A. No. 19-1544-MN (D. Del.), the parties stipulated to a judgment of non-infringement after the Court construed certain terms of the patent, and then appealed to the Federal Circuit.
The Federal Circuit vacated the stipulated judgment because it found it was not specific enough, and remanded the case. See AlterWAN, Inc. v. Amazon.com, Inc., 63 F.4th 18, 23 (Fed. Cir. 2023) (“[W]e cannot ‘ascertain the basis for the judgment’ of non-infringement, . . . because the parties did not adequately explain how the claim construction rulings related to the accused systems.”).
"Yes, your honor, it literally meets the claim elements of an 'animal' in a 'structure' with a 'gable roof.' But under the reverse doctrine of equivalents . . ."Go to Tomas Tuma's profile Tomas Tuma, Unsplash
The reverse doctrine of equivalents and ensnarement are great for accused infringers, but for whatever reason they often seem to get set by the wayside.
Reverse doctrine of equivalents has a terrible name. It's really just the argument that even if the accused product meets the literal elements of the claim, it does not infringe because it is performs the claimed function in a substantially different way than the claimed invention.
The parties in Stragent, LLC v. Volvo Car USA, LLC, C.A. No. 22-293-JDW (D. Del.) filed a joint appendix of exhibits alongside some supplemental SJ briefing. The defendant filed a motion to seal its SJ brief, which apparently discussed internal software specifications.
The Court granted the motion to seal the SJ brief, but criticized the brief in strong terms:
Volvo seeks to file its supplemental summary judgment brief under seal, but it’s supporting brief doesn’t say much. For example, while Volvo makes generic references to “proprietary commercial, financial and business information” and …
Where IPRs are concerned, post-institution stays are fairly routine. But there are also instances where cases are not stayed, and it can lead to surprising results. For example, we talked last year about a case where where a defendant won on invalidity in an IPR, but had to proceed to trial anyway—and faced estoppel on their prior art.
We saw an order in a somewhat similar category this week, when Judge Williams denied a post-trial motion to stay following the invalidation of the asserted claims by the PTO in an ex parte reexamination:
ORAL ORDER: Having reviewed the Joint Status Report, D.I. 1856, filed by the parties on October 23, 2023, the Court …
