In another ruling from the In Re ChanBond litigation as it approaches trial, Judge Andrews today issued an in-depth opinion granting a motion in limine to exclude reference to prior expert testimony from a related IPR proceeding, on the grounds that the testimony is hearsay.

Plaintiff sought to admit the material as former testimony under FRE 804(b)(1), because it is helpful to its infringement case. The rule requires, however, that the former testimony was offered against the parties' predecessor who had "an opportunity and similar motive to develop it."

Here, Judge Andrews found that an IPR petitioner's motive in developing expert testimony to show invalidity is different from a defendant's motive developing its non-infringement position:

I …

Judge Andrew's In re Chanbond opinion an Friday focused primarily on reopening discovery, but it also addressed a second issue, which I thought merited a separate post.

Shortly before trial, in a reply brief, Defendants sought production of an "Advisory Services Agreement" between the plaintiff and third party IPNav. They had previously informally requested the document at a deposition, and renewed that request as part of their motion to reopen discovery after the document's importance became apparent in light of the standing dispute. Defendants request at the deposition was apparently on the record, and Plaintiff indicated it would look for the document, but Defendants did not follow up with a formal document request:

I agree with Plaintiff that Defendants …

In In Re Chanbond, LLC Patent Litigation, Judge Andrews denied a request for post-pretrial-order discovery on Friday. The request came after Defendants received an e-mail from attorneys from third-party Deirdre Leane alleging that her consent was required for any settlement between the defendants and plaintiff ChanBond:

On September 2, 2020, Defendants received an email from Ms. Leane’s counsel, informing them of a dispute between Ms. Leane and ChanBond. . . . The email stated, “As we read Section 8.3 of the ISA, Ms. Leane’s written consent is required given that a license is a transfer of an interest in the patents-in-suit, which in turn are material assets of ChanBond.” . . . The email warned, “[P]lease take notice …

We've noted previously that it is tremendously difficult to win a motion for interlocutory appeal in Delaware (and pretty much everywhere else). So it comes as no surprise that litigants—innovators all—will occasionally come up with new ways to achieve the same result without all the difficulties attendant with actually moving. We now know that at least one of these methods does not work.

The parties in Malvern Panalytical, Inc. v. TA Instruments-Waters LLC, C.A. No. 19-2157-RGA (D. Del.) filed a joint stipulation dismissing the 5-patent case following a claim construction opinion that apparently definitively absolved the defendant of infringing 2 of the patents. Id., D.I. 163. The stipulation, however, only dismissed the claims as to those 2 patents with prejudice while specifically reserving the plaintiff's right to "reassert the [remaining] [p]atents in the future, including in the event of a reversal and remand to this Court following the expected appeal from the final judgment entered pursuant to this Joint Stipulation of Non-Infringement." Id.

Despite that fact that this was a joint stipulation ...

Earlier today, Judge Burke unsealed an interesting order addressing the applicability of the common-interest doctrine to communications between a generic pharmaceutical company and its API manufacturer.

No attorneys directly participated in most of the underlying communications, but the defendants argued that they shared "a common legal interest" with their API manufacturer in avoiding a lawsuit "and that their communications furthered that interest." Although Judge Burke found that this "argument has some initial, superficial appeal[,]" in that "the subject of these communications is in some sense legal in nature[,]" he concluded that any shared legal interest came too late:

when one contextualizes the communications with regard to what was happening in the relevant time period, Defendants have not met …

In response to early Section 101 motions, plaintiffs often assert that claim construction is necessary before a ruling on patent eligibility can occur. For plaintiffs looking for quick settlements and dismissals, avoiding an early ruling on Section 101 is a win. In most cases, successfully arguing that claim construction is required pushes the timeline out for resolution of Section 101 issues substantially. That is not always the case, however. Judge Stark recently ordered an "expedited Markman proceeding" on terms the plaintiff had identified during Section 101 briefing, short-circuiting the usual process and setting up a possible second round of Section 101 motions.

Judge Connolly put this oral order on the docket on Thursday:

ORAL ORDER: The Court has read Plaintiffs' April 7 letter . . . . The Court understood Mr. Groombridge's response to be in substance what Plaintiffs outline in their letter. The Court asked an imprecise question. But the Court had in mind what Mr. Groombridge had in mind. Mr. Groombridge has appeared before the Court on numerous occasions and the Court appreciates and respects his practice of conceding points he should concede and getting to the heart of the disputed matters before the Court. All counsel would do well to follow his lead in that regard.

Amgen Inc. v. Hospira, Inc., C.A. …

Just as Delaware gears up to resume jury trials, Judge Stark has released his post-trial opinion for his first fully remote trial of the pandemic in AO Smith Corp. v. Bradford White Corp., C.A. No. 18-412-LPS.

The opinion -- long in the manner of all post-trial opinions -- is worth a read in full. But for my money the main takeaway is how large a roll witness credibility appeared to play in the final outcome, as the difficulty in assessing these things has long been an argument against fully remote trials.

As often happens, the infringement case amounted to a battle of the experts, and there does not appear to be any dispute about who won. Somewhat unusually, the …

Pop quiz: What's the easiest way to get your SJ motion denied in a single page? Answer: Tell the judge that a disputed fact is material to your motion.

Several of the D. Del. judges require parties to include a concise statement of material facts with their summary judgment motions. This is exactly what it sounds like: a statement of each fact that the moving party contends is (a) essential to resolve the motion and (b) undisputed.

Judge Noreika, Judge Connolly, and Magistrate Judge Hall each require a concise statement to be filed with the opening brief, as well as a responsive statement with the answering brief. Judge Noreika and Magistrate Judge Hall also require …

Despite a 2020 change in the law designed to make obtaining a preliminary injunction easier for plaintiffs in trademark cases, Judge Stark denied a trademark plaintiff's motion for preliminary injunction, finding that the defendant had effectively rebutted the statutorily-imposed presumption of irreparable harm.

In Nichino America, Inc. v. Valent U.S.A., LLC, C.A. No. 20-704-LPS, the plaintiff sought preliminary injunctive relief, arguing that the defendant's use of the Senstar mark in connection with an insecticide product was infringing its Centaur mark, also used to market insecticides. After applying the ten-factor Lapp test, Judge Stark concluded that the plaintiff had shown a likelihood of confusion and thus …
