The opinion of the court was delivered by: Ellen Segal Huvelle United States District Judge
Plaintiff Malibu Media, LLC, the owner of the copyright for a movie entitled "Pretty Back Door Baby" (the "Movie"), has sued 11 Doe defendants alleging that they infringed plaintiff's copyright by downloading a portion of the Movie by means of the BitTorrent protocol. (Complaint, July 9, 2012 [Dkt. No. 1] ("Compl.") ¶¶ 11, 14--42.) Plaintiff's complaint identifies the Doe defendants by their Internet Protocol ("IP") addresses only. (Id., Ex. B.) On July 9, 2012, the Court granted in part and denied in part plaintiff's motion for leave to serve third party subpoenas on the Doe defendants' internet service providers (ISPs) prior to a Rule 26(f) conference. (See Order, July 9, 2012 [Dkt. No. 5].) The Court's July 9 Order permitted plaintiff to subpoena the Doe defendants' ISPs, but required the ISPs to provide notice to the targeted subscribers that plaintiff was seeking their identifying information at least ten days prior to providing plaintiff with that information. (See id. at 1 (citing Malibu Media, LLC v. John Does 1--16, No. 12-cv-0235, 2012 WL 1681819, at *2 (D.D.C. April 11, 2012)).)
Before the Court is John Doe 7's Motion to Dismiss or Sever for Misjoinder (Aug. 23, 2012 [Dkt. No. 9] ("Doe Mot.")) and plaintiff's opposition (September 6, 2012 [Dkt. No. 12]
("Pl. Opp'n")). Doe 7 argues that he and the other Doe defendants have been improperly joined in this single action and that, pursuant to Fed. R. Civ. P. 21, severance and dismissal are proper. For the reasons stated, the Court will grant Doe 7's Motion and dismiss Does 2--11 from this case without prejudice.
The legal principles governing severance and joinder are well established.
"The court may sever claims if parties are improperly joined." Davidson v. Dist. of Columbia, 736 F. Supp. 2d 115, 119 (D.D.C. 2010) (citing Fed. R. Civ. P. 21). "In determining whether parties are misjoined for purposes of Rule 21, courts apply the permissive joinder requirements of Rule 20(a)." Id. (citing Montgomery v. STG Int'l, Inc., 532 F. Supp. 2d 29, 35 (D.D.C. 2008)). Defendants are properly joined if "any right to relief is asserted against them . . . with respect to or arising out of the same transaction, occurrence, or series of transactions or occurrences," and if "any question of law or fact common to all defendants will arise in the action." Fed. R. Civ. P. 20(a)(2). "[T]he two prongs of Rule 20(a) 'are to be liberally construed in the interest of convenience and judicial economy . . . in a manner that will secure the just, speedy, and inexpensive determination of th[e] action.'" Davidson, 736 F. Supp. 2d at 119 (second and third alterations in the original) (quoting Lane v. Tschetter, No. 05-cv-1414 (EGS), 2007 WL 2007493, at *7 (D.D.C. July 10, 2007)). If the Rule 20(a) test is not satisfied, however, then defendants are not properly joined and the claims against them can be severed under Rule 21. See, e.g., id. at 119--22.
Pursuant to the first prong of the Rule 20(a) test, [plaintiff's] claims against defendants "aris[e] out of the same transaction, occurrence, or series of transactions or occurrences," Fed. R. Civ. P. 20(a)(2), only if they are "'logically related.'" Maverick Entm't Grp., Inc. v. Does 1--2,115, 810 F. Supp. 2d 1, 12 (D.D.C. 2011) (quoting Disparte v. Corporate Exec. Bd., 223 F.R.D. 7, 10 (D.D.C. 2004)); accord Bederson v. United States, 756 F. Supp. 2d 38, 54 (D.D.C. 2010). "The logical relationship test is flexible because 'the impulse is toward entertaining the broadest possible scope of action consistent with fairness to the parties; joinder of claims, parties and remedies is strongly encouraged.'" Disparte, 223 F.R.D. at 10 (quoting United Mine Workers of Am. v. Gibbs, 383 U.S. 715, 724 (1966)). Yet, [plaintiff] "cannot join defendants who simply engaged in similar types of behavior, but who are otherwise unrelated; some allegation of concerted action between defendants is required." Grynberg v. Alaska Pipeline Co., No. 95-cv-725(TFH), 1997 WL 33763820, at *1 (D.D.C. March 27, 1997) (emphasis added); see id. at *2 (examining cases and concluding that "[c]courts have not joined totally independent actors, without any allegation of concert or conspiracy" (citing United States v. Mississippi, 380 U.S. 128 (1965); Nassau Cnty. Ass'n of Ins. Agents v. Aetna Life & Cas., 497 F.2d 1151 (2d Cir. 1974); Cohen v. Dist. of Columbia Nat'l Bank, 59 F.R.D. 84 (D.D.C. 1972))). Spaeth v. Mich. State Univ. Coll. of Law, 845 F. Supp. 2d 48, 53 (D.D.C. 2012) (footnote omitted, citation format altered).*fn1
The Court concludes that plaintiff has not satisfied the Rule 20(a) test because plaintiff has not alleged concerted action among the Doe defendants. Plaintiff alleges that each Doe defendant used BitTorrent, a "common peer-to-peer file sharing protocol" (Compl. ¶ 14), to download the same piece of a larger file containing the Movie. (See id. ¶¶ 16--42.) Key to plaintiff's joinder theories are the following allegations:
Once a peer receives a piece of the computer file, here a piece of the [Movie], it starts transmitting that piece to the other peers. . . . In this way, all of the peers and seeders are working together in what is called a "swarm." . . . Here, each [Doe defendant] peer member participated in the same swarm and directly interacted and communicated with other members of that swarm through digital handshakes, the passing along of computer instructions, uploading and downloading, and by other types of transmissions. (Id. ¶¶ 31--33.*fn2
"[A] growing number of district courts have recently held that swarm joinder is not appropriate." Malibu Media, LLC v. John Does 1--54, No. 12-cv-1407, 2012 WL 3030302, at *2 (D. Colo. July 25, 2012) (collecting cases); see also Raw Films, Inc. v. Does 1--32, No. 1:11-cv-2939, 2011 WL 6840590, at *2 (N.D. Ga. Dec. 29, 2011) (The swarm joinder theory "has been considered by various district courts, the majority of which have rejected it."). This Court agrees.*fn3 "[A] plaintiff must allege facts that permit the court at least to infer some actual, concerted exchange of data between [the Doe defendants]." Malibu Media, LLC v. John Does 1-- 54, 2012 WL 3030302, at *2 (internal quotation marks and citation omitted). Plaintiff has not done so here.
Nothing in the complaint negates the inference that the downloads by the various [Doe] defendants were discrete and separate acts that took place at different times; indeed, the complaint alleges that separate defendants shared access to a file containing a pornographic film in separate and isolated incidents over the course of  days. [(See Compl., Ex. B.)] In other words, what we have here [are 11] separate and discrete transactions in which  individuals used the same method to access a file via the Internet-no concerted action whatever, and no series of related occurrences-at least, not related in any way except the method that was allegedly used to violate the law.
Digital Sins, Inc. v. John Does 1--245, No. 11-cv-8170, 2012 WL 1744838, at *3 (S.D.N.Y. May 15, 2012).*fn4
"There is no need for this Court to write another lengthy opinion discussing why plaintiff's theory is wrong." Id. at *2; see also Malibu Media, LLC v. John Does 1--54, 2012 WL 3030302, at *3 ("Given the amount of discourse already produced by courts around the country on this issue, the Court finds it unnecessary to write a lengthy opinion about whether joinder is appropriate."). Rather, the Court explicitly adopts the reasoning put forward by Judge McMahon in Digital Sins, Inc. v. John Does 1--245, 2012 WL 1744838, at *1--4, by Judge Motz in Patrick Collins, Inc. v. Does 1--23, No. 8:12-cv-087, 2012 WL 1144918, at *1--7 (D. Md. April 4, 2012), and by Magistrate Judge Spero in Hard Drive Productions, Inc. v. Does 1--188, 809 F. Supp. 2d 1150, 1157--65 (N.D.
