"Back in my day, we locked our first year associates in a room stacked with banker's boxes for weeks on end! None of this 'search term' mumbo jumbo!" AI-Generated, displayed with permission

Judge Williams issued a lengthy decision today in GlaxoSmithKline Biologicals SA v. Pfizer Inc., C.A. No. 24-512-GBW (D. Del.), addressing a number of disputes relating to proposed protective and ESI orders in multiple related actions.

There is a lot of interesting material in the decision, but one ruling in particular caught my eye, because it's an issue that comes up a lot: whether a party has to use search terms to search ESI.

Most, but not all, of our judges have adopted the Court's Default Standard for Discovery, Including Discovery of Electronically Stored Information ("ESI")—a document that, despite it's catchy name, is usually referred to as the "Default Standard."

The Default Standard places the option of using search terms in the producing party's hands:

If the producing party elects to use search terms to locate potentially responsive ESI, it shall disclose the search terms to the requesting party. Absent a showing of good cause, a requesting party may request no more than 10 additional terms terms to be used in connection with the electronic search. Focused terms, rather than over-broad terms (e.g., product and company names), shall be employed. The producing party shall search (i) the non-custodial data sources identified in accordance with paragraph 3(b); and (ii) emails and other ESI maintained by the custodians identified in accordance with paragraph 3(a).

Thus, producing parties sometimes decide not to use search terms, and to instead review and produce their ESI the old-fashioned way (potentially including hours of brutal contract-attorney document-by-document review).

Occasionally the opposing party will ask the producing party to use search terms. In cases governed by the Default Standard, I would expect a producing party to feel little pressure in responding "no," since the Default Standard recognizes that using search terms is optional.

In GlaxoSmithKline, however, the Court ...

Discovery on discovery -- i.e., discovery asking how you're collecting documents, or when you started your litigation hold, or why all your documents smell like bubblegum -- is generally not allowed in Delaware (and most other districts I'm aware of). To get that sweet, sweet, disco on disco, you need to make a "threshold showing that significant, relevant, and non-cumulative information has been withheld or overlooked." British Telcoms. PLC v. IAC/Interactivecorp,. C.A. No. 18-366-WCB, 2020 U.S. Dist. LEXIS 37271, at *21 (D. Del. Mar. 4, 2020). This is a pretty big ask in the context of a discovery dispute, so we only rarely see the issue come up.

We missed an interesting decision from Judge Fallon last month. In Marquinez et al v. Dole Food Company Inc., C.A. No. 12-695-RGA-SRF, D.I. 582 (D. Del. Apr. 24, 2025), Judge Fallon rejected an attempt to "recycle" an expert opinion from a prior, related action.

Apparently the plaintiff had previously retained the experts, and attempted to re-use their prior expert opinions, by admitting the transcript of their prior testimony:

The Hendler Declaration confirms that both witnesses were formally retained as expert witnesses in a prior litigation, they served expert reports in the prior litigation, and both were asked but declined to serve as retained expert witnesses in this case. (D.I. 580 at ¶¶ 9-13) Plaintiffs …

The difficulty with a request for admission is right there in the name. When someone asks you to admit that you did something, it's only natural that you push back a bit, whatever the admission may be.

Admit that you were the one who brought the potato salad!

Admit that you were wearing a striped suit!

Admit that you love conures!

But even if one overcomes these hurdles, there are further difficulties in RFA practice, waiting under every upturned rock. For instance, many scheduling orders place a limit on the number of RFAs that can be propounded, and so, like with rogs, there may be a dispute over whether a given RFA covers too much ground. Such was the case in Friday's decision in Scale Biosciences, Inc. v. Parse Biosciences, Inc., C.A. No. 22-1597-CJB, D.I. 410 (D. Del. May 23, 2025).

In that case, the plaintiff sent RFAs asking the defendant to "Admit that the following graphic illustrates, at least in part, the operation of the Parse Mini, Parse Mid Products, and Parse Mega Products," and several similar RFAs directed to several products. Defendant objected that ...

Sad Lawyer Clown

Blogging about legal topics as an attorney can be tough. We at IP/DE post very frequently for a legal blog written by active, practicing attorneys, and I've occasionally been asked by other attorneys how it's going. I thought I'd offer some thoughts on legal blogging here at IP/DE, after 5 years of it, and about the successes and challenges we've faced.

(This was originally part of our Celebrating 5 Years post, but it was honestly kind of a buzz kill. So I followed my wife's wise advice to "split that part into its own post and add a sad clown face.")

Happy birthday to us! Believe it or not, IP/DE launched on May 25, 2020, so as of Sunday, this blog will be 5 years old.

Many many thanks to all of our contributors—both to our authors (Nate, Emily, and Lindsey, and former writers Jeff Castellano and David Fry) and to all of those in the community who have sent in post ideas and other thoughts over the last five years. We couldn't have done it without you!

As we discuss in today's post about the state of IP/DE, we hope to keep it up!

The service rules are relics of a different time. A time when New York and Vermont would occasionally shoot half-heartedly at one another over the land between the Connecticut and Hudson rivers—an area now mostly known for being the world's most boring drive.

In any event, the requirements remain and thus we are occasionally forced to make some poor courier drive to someplace terrible (see above) to drop off a paper packet. That's rule 4, for ya.

But the rules get a bit squishy if your defendant is foreign-based. FRCP 4(f)(1) initially suggests you might want to use the Hague convention, which is a great idea if you are a meticulous masochist. FRCP 4(f)(3) is where things get a bit more interesting, allowing service by "other means not prohibited by international agreement, as the court orders."

Naturally, very few means of service are specifically prohibited by international agreement. Yodeling, smoke signals, a swarm of vicious bees—all are typically fine under the relevant treaties.

This leads us to the case of the intrepid ...

Try not to forget that jury demand.

Other than in ANDA cases, most (but not all) patent cases these days involve a demand for jury trial. FRCP 38 sets a deadline for requesting a jury trial within 14 days after the last pleading directed to the issue is served:

On any issue triable of right by a jury, a party may demand a jury trial by . . . serving the other parties with a written demand—which may be included in a pleading—no later than 14 days after the last pleading directed to the issue is served; and . . . filing the demand . . . .

FRCP 38.

This rule includes a few interesting things, just from the text:

  • It sets out the demand requirement by issue, not by action
  • It says parties "may" include the jury demand in a pleading, not that they must
  • A party gets 14 days after service of the "last pleading directed to the issue" to serve a jury demand

District of Delaware Local Rule 38.1 also covers this issue, and defines the acceptable language for a jury demand in a pleading:

If a party demands a jury trial by endorsing it on a pleading, as permitted by Fed. R. Civ. P. 38(b), a notation shall be placed in the caption of the pleading stating "Demand For Jury Trial" or the equivalent. This notation will serve as a sufficient demand under Fed. R. Civ. P. 38(b).

D. Del. LR 38.1.

In my experience, parties who want to request a jury trial almost always ...

It has been pointed out that many of my references are so oblique as to be indecipherable. Rather than improve the practice, I have resolved to simply include a footnote at the bottom of each post, lest they go unappreciated.

Anyway, today's case is Cosmokey Solutions GmbH v. Duo Security, Inc., C.A. No. 18-1477-JLH-CJB (D. Del. May 19, 2025).

The defendant there brought a Daubert motion to preclude the plaintiffs' experts testimony on the grounds that he offered a "legally wrong construction" of one of the claim terms. Naturally, this motion was brought long after the Court issued its Markman order. Neither party had proposed …

This is basically what I imagine when I hear about a "corporate deponent" Chris Barbalis, Unsplash

On Friday, the Court unsealed an interesting Judge Bryson opinion on 30(b)(6) depositions.

As we've noted, Rule 30(b)(6) now parties to meet-and-confer prior to the deposition to resolve the scope of the testimony. But the rules leaves out the exact parameters of how and when parties object, and what happens when they do.

Judge Bryson's opinion addresses an instance where a responding party objected to a 30(b)(6) notice, designated witnesses on only portions of the noticed topics, and offered to meet-and-confer (an offer the noticing party never accepted).

As promised, the deponent was prepared to testify on only a portion of the …
