The District of Delaware supports contention interrogatories generally (but not contention 30(b)(6) topics). I remember that, back before the Court adopted the Default Standard in 2011, contention interrogatories were the main way to define and limit the scope of the case during fact discovery.

But contention interrogatories are not without limits. On Friday, in LeFebvre v. Extrabux, Inc., C.A. No. 23-167 (D. Del.), Judge Burke issued a decision on a discovery dispute about a contention interrogatory seeking claim construction positions. He held that a party can't just ask the opposing party for its …

Last month, we wrote about the Mavexar-related witness who spent about $44,400 and counting just to avoid a trip to Delaware. Our post was prompted by the Federal Circuit affirming Judge Connolly's order imposing sanctions for her failure to appear in-person (even though, oddly, she agreed to appear remotely) for questioning by the Court related to potential misbehavior by her LLC, its attorneys, and Mavexar/IP Edge.

Well, yesterday the Court set a new hearing date, once again ordering the witness to appear for an in-person examination by the Court:

At Wilmington on this Twenty-third day of August in 2024, having received the Federal …

Money—Exactly the thing that this accused infringer may not actually wind up collecting

We're back! During our brief intermission, the Court issued an exceptional case finding in Wireless Discovery LLC v. eHarmony, Inc., C.A. No. 22-480-GBW (D. Del.), and awarded fees.

I always like reading these opinions both (1) as a guide on what not to do and (2) to figure out how to better threaten NPEs with the risk of fee awards. I'm not sure this one is going to be particularly helpful in those regards, because there were some exceptional facts.

First, the patentee filed a patent that asserted previously invalidated claims. Worse, after the accused infringer called them …

For some reason, one of the references stands out...

Judge Bryson unsealed a discovery dispute opinion last week in Impossible Foods Inc. v. Motif Foodworks, Inc., C.A. No. 22-311-WCB (D. Del.), addressing a motion to supplement infringement contentions after the deadline for final contentions. The patentee argued that it had good cause to supplement because it did so quickly after the accused infringer added a totally new prior art reference in their final invalidity contentions.

There are a couple of interesting things about the opinion, but I wanted to call out one in particular.

The case included a deadlines for final contentions, and then for case narrowing, with the defendant to drop to a list of 10 references. The defendant initially cut …

Chief Judge Connolly issued an opinion today addressing whether a claim to a COVID "vaccine" can extend to something that is not a "vaccine," and ultimately calling for the Federal Circuit to address its inconsistent precedent on construction of patent claim preambles.

The claims at issue claimed "[a] vaccine comprising . . ." a certain formulation. They agreed on what a vaccine is, but disagreed as to whether that term in the preamble to the claims should be limiting:

What the parties dispute is whether the term "vaccine" is "limiting" in claims 27 and 28. "Limiting" is patent-speak for "is an element of the claim." . . . Notwithstanding the fact that claim 27 …

I've noticed that, since November of last year, Judge Burke has been issuing claim construction opinions in some cases in the form of a series of oral orders on the docket, rather than a formal memorandum opinion or an order with footnotes. I thought I'd flag this so that people know what may happen if you have claim construction in a case before Judge Burke.

I first saw the Court construe terms via oral orders on the docket in November 2023, in The Nielsen Company (US), LLC v. TVision Insights, Inc., C.A. No. 22-057, D.I. 140-141 ( …

Last week in Ignite Enterprise Software Solutions, LLC et al. v. NGData, US Inc. and NGData N.V., C.A. 23-1209 (D. Del. Aug. 2, 2024), Judge Murphy dinged defendants for stale citations, including failing to cite recent Federal Circuit precedent on the level of detail required in patent pleadings.

We flagged the case that this Court called the "most recent and most relevant Federal Circuit authority" back when it came out: Bot M8 LLC v. Sony Corp. of Am., C.A. No. 2020-2218, 2021 U.S. App. LEXIS 20624 (Fed. Cir. July 13, 2021).

"By careful review of literally just the face of the patent, we have determined that the conception date is no later than the 2/3/2017 filing date. You're welcome." AI-Generated, displayed with permission

I admit, sometimes I write about things because I want to be able to find them next time I need them. This is one of those posts.

As we've discussed before, most patent cases involve an interrogatory to the patentee asking for the date of conception. Patentees often give a low-effort initial response along the lines of "no later than x," where x is the date of filing or some other easy-to-identify date. Then they wait to see whether they need an earlier date, and supplement if so.

This has two benefits for the patentee: (1) it makes it hard for the accused infringer to weigh the relative merits of the prior art, because it has to hit a moving target, and (2) it's super easy, because the patentee doesn't have to review any of the materials. Thus, it's a common response.

The Court has rejected this response in the past, including the idea that "[a patentee] has no obligation to investigate whether the patent-in-suit is entitled to an earlier priority date at least until Defendant has provided its invalidity contentions." The Court in that transcript forced the patentee to actually respond to the interrogatory—making it a handy transcript for accused infringers.

But as of today we have ...

There's a patent trial starting on Monday in Ferring Pharmaceuticals Inc. v. Finch Therapeutics Group, Inc., C.A. No. 21-1694-JLH (D. Del.), and filings are flying back and forth across the docket this week. The Court's order on motions in limine included this line, which piqued my interest:

To say that the Court is troubled by the occurrences to date would be an extreme understatement.

What was so troubling? It's tough to decipher exactly what is going on from the docket, which is fragmented and redacted. But it has to do with the parties' actions related to an inventor of certain of the asserted patents.

As far as I can tell, the allegations are …

Parties in patent cases often fight about the sufficiency of infringement and invalidity contentions. Parties may offer broad initial contentions, keeping their options open as the case develops and avoiding the cost of detailed contentions. The opposing party, though, may want detailed contentions to narrow and explain the case and to tie parties to their positions.

Often, one side or the other moves to compel more detailed contentions knowing that, if they lose and if the opposing party refuses to supplement, they will be better positioned to exclude the more detailed contentions inevitably offered later.
