STEWART D. AARON, United States Magistrate Judge: Presently before the Court is a dispute regarding a privileged document referred to by the parties as the “Inaba Memo,” which is a January 30, 2009 document authored by Atsuhiro Inaba (“Inaba”),* the first page of which contains the production page number TAKACTOS_ 000527151. (See Pls.’ 7/25/23 Ltr. Mot., ECF No. 531/532, at 2 & Ex. A (ECF No. 531-2).) For the reasons set forth below, the Court finds that Takeda has waived privilege with respect to the Inaba Memo. BACKGROUND This is an antitrust class action in which Plaintiffs allege that 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 (“FDA”). See In re Actos End-Payor Antitrust Litig., 848 F.3d 89, 92 (2d Cir. 2017). As part of its regulatory compliance defense, Takeda chose to expressly waive privilege with respect to the applicability of pre-2003 regulations governing the submission of patent information to the FDA for the two subject

Inaba, an employee of Takeda’s Japanese parent company, Takeda Pharmaceutical Company Limited (Defs.’ 4/7/22 Ltr., ECF No. 487, at 4), was identified in contemporaneous email communications as “Chief Patent Counsel” for Takeda Pharmaceuticals North America, Inc. (See, e.g., 10/18/20 Takeda email, ECF No. 483-6.)

patents, and Takeda’s compliance with the pre-2003 regulations. See In re Actos Antitrust Litig., 628 F. Supp. 3d 524, 534-35 (S.D.N.Y. 2022). Following Takeda’s waiver of privilege, the Inaba Memo was produced by Takeda in 2022.

(See Pls.’ 9/8/22 Ltr. Reply, ECF No. 405, at 13-14; Defs.’ 7/28/23 Ltr. Resp., ECF No. 536, at 1.)2 The Inaba Memo later was filed by Plaintiffs under seal on September 8, 2022 as an exhibit to a Letter Reply filed by Plaintiffs regarding documents subject to Takeda’s privilege waiver. (Pls.’ 9/8/22 Ltr. Reply, Ex. F, ECF No. 405-6.) On September 9, 2022, during a telephone conference with the Court addressing the scope of Takeda’s waiver, Takeda’s counsel stated on the record that Takeda was not seeking to claw back the Inaba Memo. (See 9/9/22 Tr., ECF No. 410, at 6

(“No, we are not proposing to claw back any of the documents that are attached to the reply brief.”).) In addition, Takeda’s counsel stated, with respect to the documents that were exhibits to Plaintiffs’ Letter Reply (which included the Inaba Memo), that Takeda had “endeavored to produce documents that related to the subject matter of the waiver.” (Id.; see also id. at 5 (“we did intend to produce those documents”).) Thereafter, on September 16, 2022, this Court issued

its Opinion and Order regarding the scope of Takeda’s waiver of privilege. See In re Actos Antitrust Litig., 628 F. Supp. 3d at 534-36. On November 4, 2022, during a meet and confer regarding the scope of Takeda’s privilege waiver, counsel for Plaintiffs and counsel for Takeda specifically discussed the Inaba Memo. (See Weiner Decl., ECF No. 532-1, ¶ 2.) During the meet and confer, Plaintiffs’ counsel reminded

2 On the present record, it is unclear whether Takeda first produced the Inaba Memo in August 2022, as Takeda posits (see Defs.’ 7/28/23 Ltr. Resp. at 1), or in May 2022, as Plaintiffs state. (See Pls.’ 7/25/23 Ltr. Mot. at 1; Fernández-Silber Ltr., ECF No. 531-6, at PDF p. 6; see also Pls.’ 7/31/23 Reply, ECF No. 537 at 3 n.4 (“Plaintiffs’ document management system shows the Inaba Memo was produced in a May 2022 production. Takeda asserts that it was first produced unredacted on August 8, 2022.”).) Takeda’s counsel that the Inaba Memo had been attached to a filing made by Plaintiffs on September 8, 2022, and that Takeda’s counsel represented at the hearing on September 9, 2022 that the document would not be clawed back. (See id.) Takeda’s counsel never stated during the

meet and confer that the Inaba Memo was inadvertently produced and would be clawed back. (See id.) On February 27, 2023, Plaintiffs sent Takeda a letter regarding Takeda’s assertions of privilege. (Pls.’ 2/27/23 Ltr., ECF No. 532-5.) In that letter, Plaintiffs identified the Inaba Memo and requested that the cover email be produced without any redactions. (See Pls.’ 7/25/23 Ltr. Mot at 2; see also Pls.’ 2/27/23 Ltr. at PDF p. 5 (identifying TAK-ACTOS_000527151).) Following

another meet and confer between counsel, Takeda agreed to re-review the documents subject to the letter. (Pls.’ 7/25/23 Ltr. Mot at 2.) As a result of its review, Takeda did not claw back the Inaba Memo but, on March 17, 2023, Takeda reproduced the Inaba Memo, removing the earlier redactions to the cover email. (Id.) Later, on April 3, 2023, Plaintiffs again filed the Inaba Memo under seal, this time in

connection with Plaintiffs’ Letter Motion to compel Takeda to produce documents subject to the Court’s September 16, 2022 Order. (See Fernández-Silber Decl., Ex. A, ECF No. 480-1, at PDF pp. 13-15.) On April 7, 2023, Takeda’s counsel sought to claw back the Inaba Memo, pursuant to Section 11 of the Protective Order,3 on the ground that it had been inadvertently produced. (See

3 Section 11(a) of the Protective Order provides in relevant part: The inadvertent production of any document, by any party or person, that such party or person later claims should have been withheld on grounds of a privilege (an “Inadvertently Produced Privileged Document”), including but not limited to the attorney-client privilege, the work product doctrine, a joint defense or common interest privilege, or other applicable privilege will not be deemed, in itself, to waive any privilege DiMattio 4/7/23 Email, ECF No. 531-6, at PDF p. 5.) On April 11, 2023, at 1:31 p.m., Plaintiffs’ counsel sent by email a detailed letter explaining why they opposed the claw back and arguing that “the circumstances surrounding Takeda’s production of the Inaba Memo clearly indicate

intentional disclosure.” (See Fernández-Silber Ltr., ECF No. 531-6, at PDF pp. 4-8.) On April 11, 2023, at 5:31 p.m., Takeda’s counsel responded by stating: “We are investigating the statements in your letter regarding TAK ACTOS_000527151.” (See Huyett 4/11/23 email, ECF No. 531-6, at PDF pp. 3-4.) Then, on the evening of April 12, 2023, Takeda’s counsel sent an email stating that, although they were “maintain[ing] [their] position that unredacted portions of TAK-

ACTOS_000527151 were inadvertently produced,” they were agreeing to withdraw their claw back “in light of the statements made during the September 9, 2022 hearing and the passage of time.” (See 4/12/23 Fee email, ECF No. 531-6, at PDF p. 3.) Takeda asserts that, in the course of preparing Inaba for his deposition in July 2023, Takeda’s counsel learned for the first time that the legal analysis and advice provided in the Inaba Memo was not generated by Inaba himself, but that he was recounting advice provided during a

meeting that took place in Chicago in January 2009 that was attended by Takeda in-house counsel and outside patent litigation counsel. (Defs.’ 7/28/23 Ltr. Resp. at 2.) According to Takeda, “any lingering questions as to whether the Inaba Memo was privileged and not within the scope of Takeda’s waiver. . . were put to rest by this new information.” (Id.)
