OPINION AND ORDER
STEWART D. AARON, United States Magistrate Judge:
Pending before the Court is Plaintiffs’ Letter Motion seeking to compel Defendants
Takeda Pharmaceutical Co. Ltd., Takeda America Holdings, Inc., Takeda Pharmaceuticals U.S.A.,
Inc. and Takeda Development Center Americas, Inc. (collectively, “Defendants” or “Takeda”) to
(1) produce all nonprivileged, responsive earlier-in-time emails that are part of the most-inclusive
email threads Takeda already has produced or will produce to Plaintiffs; and (2) provide privilege
log entries for earlier-in-time emails that are part of email threads redacted or withheld for
privilege. (Pls.” 3/22/22 Ltr. Mot., ECF No. 359.) For the reasons set forth below, Plaintiffs’ Letter
Motion is GRANTED IN PART and DENIED IN PART.
BACKGROUND
This is a complex antitrust class action in which Plaintiffs allege that the Takeda prevented
competitors from timely marketing a generic version of Takeda’s diabetes drug ACTOS by falsely
describing two patents to the Food and Drug Administration. See In re Actos End-Payor Antitrust
Litig., 848 F.3d 89, 92 (2d Cir. 2017). Plaintiffs are drug purchasers who allege that they wrongfully
were obliged to pay monopoly prices for ACTOS from January 2011, when Takeda’s patent on the
active ingredient in ACTOS expired, to at least February 2013, when the mass of generic market
entry occurred. See id.
This action was filed on December 31, 2013. (See Compl., ECF No. 1.) On March 18, 2015,
the Court approved the Order Governing Protocol for Discovery of Electronically Stored
Information and Hard Copy Documents (the “Discovery Protocol”) that the parties had proposed.
(See Discovery Protocol, ECF No. 193.) The Discovery Protocol calls for the production of
electronically stored information (“ESI”) in native format, together with the metadata and coding
fields set forth in Exhibit 1 to the Protocol. (See id. at 6-7 & Ex. 1.) The Protocol requires the
parties to de-duplicate the ESI that is produced, so as to avoid the production of “exact duplicate
documents.” (See id. at 4-5.) However, the Protocol nowhere provides for the production of only
the most inclusive email threads. (See generally Discovery Protocol.)
After motion practice and two appeals to the Second Circuit, on August 25, 2021, the
Circuit remanded this action to this Court. See United Food & Com. Workers Loc. 1776 &
Participating Emps. Health & Welfare Fund v. Takeda Pharm. Co. Ltd., 11 F.4th 118, 138 (2d Cir.
2021)
Beginning in February 2022, Takeda made multiple rolling productions of non-privileged
documents from 25 agreed custodians, including six in-house lawyers. (See Pls.’ 3/22/22 Ltr. Mot.
at 1; Defs.’ 3/25/22 Opp., ECF No. 362, at 1.) In its production, Takeda used email threading, “by
which a party reviews and produces the most-inclusive email in a thread.” (See Defs.’ 3/25/22
Opp. at 3.) Plaintiffs object to Takeda’s use of email threading and seek to compel Takeda to
produce what they refer to as “earlier-in-time emails,” as well as the metadata associated with
those emails. (See Pls.’ 3/22/22 Ltr. Mot. at 3; Pls.’ 3/28/22 Reply, ECF No. 366, at 3.)
Plaintiffs also seek to compel Takeda to provide privilege log entries for all emails,
including the earlier-in-time emails. (See Pls.’ 3/22/22 Ltr. Mot. at 2; Pls.’ 3/28/22 Reply at 1-2.)
Takeda responds that compelling such an approach “would impose an enormous burden.” (See
Defs.’ 3/25/22 Opp. at 2.) The parties have exchanged drafts of a privilege log protocol, but have
been unable to agree to the terms. (See Defs.’ 3/25/22 Opp., Ex. 1.)
The Court held a telephone conference on March 29, 2022, during which Plaintiffs’ Letter
Motion was addressed.
DISCUSSION
I. Email Threading
The first issue before the Court, i.e., regarding email threading, highlights the importance
of negotiating a comprehensive ESI protocol before data production is undertaken. The issue
arises here because Takeda made its initial rolling productions using email threading even though
the Discovery Protocol, by its terms, did not permit such approach.
Rule 34 of the Federal Rule of Civil Procedure requires a party to produce designated ESI.
See Fed. R. Civ. P. 34(a)(1)(A). The Federal Rules of Civil Procedure do not contain provisions
regarding the use of email threading, nor do the Local Civil Rules of this Court.1 However, Rule
1 During the March 29 conference, Takeda argued that email threading was consistent with Rule 34(b)(2),
which permits production “in a reasonably usable form or forms.” See Fed. R. Civ. P. 34(b)(2)(E)(ii).
However, Rule 34(b)(2)(E)(ii) only comes into play if the form of production is not “otherwise stipulated
or ordered by the court.” See Fed. R. Civ. P. 34(b)(2)(E). Here, the Discovery Protocol, which was approved
by Judge Abrams, called for the production of ESI in native format, together with the metadata and coding
fields set forth in Exhibit 1 to the Protocol, and did not permit the exclusion of any ESI or metadata from
production. (See Discovery Protocol at 6-7 & Ex. 1.) In addition, as the Advisory Committee Notes to the
2006 Amendments to Rule 34 make clear, where “the responding party ordinarily maintains the
information it is producing in a way that makes it searchable by electronic means, the information should
not be produced in a form that removes or significantly degrades this feature.” See Fed. R. Civ. P. 34, Adv.
Comm. Notes, 2006 Amend. In the present case, by performing threading, Takeda has degraded Plaintiffs’
ability to conduct searches of the emails for senders and recipients, as discussed below.
29 of the Federal Rules of Civil Procedure permits the parties to stipulate to procedures governing
discovery, see Fed. R. Civ. P. 29(b), for example, by use of discovery protocols. Indeed, the Sedona
Principles2 encourage the parties to have “early discussions” regarding “procedural issues
relating to the form of production,” and to enter into an “agreed upon protocol governing the
production of ESI and avoid downstream misunderstandings or disputes.” See The Sedona
Principles, Third Edition: Best Practices, Recommendations & Principles for Addressing Electronic
Document Production, 19 Sedona Conf. J. 1, Comment 3.c. (2018) (hereinafter, “Sedona Elec. Doc.
Prod. Principles”), available at https://thesedonaconference.org/publications (italics omitted);
see also id., Comment 12.b. (“Ideally, the form or forms used for production of ESI should be
agreed upon early.” (italics omitted)).
It is not uncommon for ESI protocols to address the use of email threading. As Takeda
notes, such protocols have been entered in cases in this Court. (See Defs.’ 3/25/22 Opp. at 1 n.2.)
In unrelated litigation in another federal court in which Takeda was a party, a provision was
included in a protocol regarding email threading, as follows:
E-mail Threading: The producing Party may identify e-mail threads where all
previous emails which make up the thread are present in the body of the final e-
mail in the thread. Any party electing to use this procedure must notify all
receiving parties that e-mail thread suppression has been proposed to be
performed on a specified production and the Parties agree to meet and confer
regarding the format of this production, and reserve the right to seek Court
guidance on the issue should agreement not be reached.
2 The Sedona Conference is “a nonprofit legal policy research and education organization, has a working
group comprised of judges, attorneys, and electronic discovery experts dedicated to resolving electronic
document production issues.” Aguilar v. Immigr. & Customs Enf’t Div. of U.S. Dep’t of Homeland Sec., 255
F.R.D. 350, 355 (S.D.N.Y. 2008). “Since 2003, the Conference has published a number of documents
concerning ESI, including the Sedona Principles.” Id. “Courts have found the Sedona Principles instructive
with respect to electronic discovery issues.” Id. (citation omitted).
In re Actos (Pioglitazone) Prod. Liab. Litig., No. 6:11-MD-2299, 2012 WL 7861249, at *11 (W.D.
La. July 27, 2012). But, ESI protocols must be negotiated by the parties to address any legitimate
concerns the parties to the protocol may have and no similar agreement on email threading was
reached here.
Takeda’s exclusion of lesser included emails from production has resulted in the exclusion
of the metadata associated with earlier emails in a chain (which may be weeks or even months
prior to the last email in a chain).3 This exclusion materially has reduced Plaintiffs’ ability to search
for all correspondence within a date range. In addition, in certain email chains, only the sender
of particular emails earlier in a chain are reflected, and not the recipients of such emails. (See,
e.g., Pls.’ 3/28/22 Reply, Ex. C.) Finally, Takeda’s email threading has removed Plaintiffs’ ability
to see if anyone was blind-copied on lesser included emails, even though this information was
among the metadata the parties agreed in the Discovery Protocol to produce.
If the issue of email threading had been raised at the time the parties were negotiating
the Discovery Protocol, Plaintiffs may have been able to ameliorate the foregoing issues by
including, for example, a protocol provision requiring the exchange of certain metadata for any
excluded, lesser-included emails. However, Plaintiffs were not provided the opportunity to
negotiate how email threading might be accomplished in an acceptable manner. In the
circumstances presented, and based upon careful review of the parties’ submissions, the Court,
in its discretion, declines to impose email threading on Plaintiffs. Moreover, although the Court
recognizes that the production of earlier-in-time emails will cause some additional burden on
3 Plaintiffs included with their reply examples of email chains that spanned a four- to eight-month period.
(See Pls.’ 3/28/22 Reply, Exs. E, F & G.)
Takeda, the Court finds that any additional burden is not undue since Takeda agreed to the
Discovery Protocol and likely already has reviewed many of the emails at issue. Thus, Takeda shall
produce all responsive ESI to Plaintiffs, including earlier-in-time emails.
II. Privilege Log
The parties have exchanged drafts of a privilege log protocol, but have been unable to
agree to terms regarding how email threads should be logged. (See Defs.’ 3/25/22 Opp., Ex. 1.)
However, because the Court now is requiring Takeda to produce earlier-in-time emails, which
will affect the scope of the privilege log, the parties may be able to reach an agreement on the
privilege log issue. Accordingly, the parties are directed to meet and confer to seek to agree on a
revised privilege log protocol, taking into account the Court’s ruling above. The following
discussion is designed to provide guidance to the parties regarding the terms of such protocol.
Rule 26(b)(5) provides that a withholding party must “describe the nature of the
documents, communications, or tangible things not produced or disclosed—and do so in a
manner that, without revealing information itself privileged or protected, will enable other
parties to assess the claim.” Fed. R. Civ. P. 26(b)(5)(A). Rule 26(b)(5) needs to be read in
conjunction with Local Civil Rule 26.2(c). Local Civil Rule 26.2(c) provides:
Efficient means of providing information regarding claims of privilege are
encouraged, and parties are encouraged to agree upon measures that further this
end. For example, when asserting privilege on the same basis with respect to
multiple documents, it is presumptively proper to provide the information
required by this rule by group or category. A party receiving a privilege log that
groups documents or otherwise departs from a document-by-document or
communication-by-communication listing may not object solely on that basis, but
may object if the substantive information required by this rule has not been
provided in a comprehensible form.
S.D.N.Y. Local Civ. R. 26.2(c). The Committee Note to the Rule expands on the rule, as follows:
With the advent of electronic discovery and the proliferation of e-mails and e-mail
chains, traditional document-by-document privilege logs may be extremely
expensive to prepare, and not really informative to opposing counsel and the
Court. There is a growing literature in decisions, law reviews, and other
publications about the need to handle privilege claims in new and more efficient
ways. The Committee wishes to encourage parties to cooperate with each other
in developing efficient ways to communicate the information required by Local
Civil Rule 26.2 without the need for a traditional privilege log. Because the
appropriate approach may differ depending on the size of the case, the volume of
privileged documents, the use of electronic search techniques, and other factors,
the purpose of Local Civil Rule 26.2(c) is to encourage the parties to explore
methods appropriate to each case. The guiding principles should be cooperation
and the “just, speedy, and inexpensive determination of every action and
proceeding.” Fed. R. Civ. P. 1. See also The Sedona Cooperation Proclamation,
available at www.TheSedonaConference.org, whose principles the Committee
endorses.
Id., Committee Note; see also Sedona Elec. Doc. Prod. Principles, Comment 10.h. (“Logging large
volumes of withheld ESI is often costly, burdensome, time-consuming, and disproportionate to
the needs of the case.” (citing 1993 Advisory Comm. Note to Rule 26(b)(5)).
Accordingly, categorical privilege logs are appropriately used in this Court. “[A] categorical
privilege log is adequate if it provides information about the nature of the withheld documents
sufficient to enable the receiving party to make an intelligent determination about the validity of
the assertion of the privilege.” Rekor Sys., Inc. v. Loughlin, No. 19-CV-07767 (LJL), 2021 WL
5450366, at *1 (S.D.N.Y. Nov. 22, 2021) (citation omitted). The categorical privilege log found
acceptable by Judge Liman in Rekor contained groupings of multiple documents over discrete
date ranges to and from individuals at identified firms, listing the general subject matter. (See
Priv. Log, 19-CV-07767, ECF No. 180-1.)
Plaintiffs’ proposal of permitting categorical logging of emails only where all emails
“involved the same participants and subject matter” (see Pls.’ 3/22/22 Ltr. Mot. at 1) is
inconsistent with the foregoing principles, since there is no requirement that all participants be
identical for categorical logging to be appropriate. Takeda’s proposal of only logging the threaded
emails (see Defs.’ 3/25/22 Opp. at 2) also is inconsistent with the foregoing principles, since it is
unlikely that the log would contain sufficient information for Plaintiffs to assess the claim of
privilege for each email in the thread. However, now that the Court now is requiring the
production of all responsive ESI, the parties are directed to meet and confer with respect to the
privilege log protocol, consistent with the principles set forth above, and seek to agree to terms.
CONCLUSION
By reason of the foregoing, Plaintiffs’ Letter Motion is GRANTED IN PART and DENIED IN
PART. Takeda shall produce all responsive ESI to Plaintiffs, including earlier-in-time emails. In
addition, the parties are directed to meet and confer and seek to agree to terms of a privilege log
protocol. No later than April 15, 2022, the parties shall file to the ECF docket the agreed-upon
privilege log protocol, for approval by the Court. If the parties are unable to agree to the terms
of a privilege log protocol, then, no later than April 15, 2022, the parties shall file to the ECF
docket their competing proposals.
SO ORDERED.
