24 INTRODUCTION 25 In this false-advertising action, plaintiff moves for a permanent injunction, which would 26 depart from the now-in-place interim injunction based on new information, and for entry of 27 default judgment. For reasons and to the extent below, the motion is granted in part and denied 1 STATEMENT 2 1. THE CLAIMS AND PROCEDURE PROMPTING INTERIM RELIEF. 3 Plaintiff KHN Solutions LLC makes blood-alcohol concentration breathalyzers (2d Amd. 4 Compl. ¶¶ 44–48). Defendants make breathalyzers, too — but theirs don’t work and are 5 popularized by fake reviews and false quality assurances on www.amazon.com (see id. ¶¶ 1–8, 6 12–39). So, plaintiff brought false-advertising claims under federal and state law (id. ¶¶ 87– 7 108). 8 The magistrate judge overseeing the case ultimately granted alternative service via email 9 (see Dkt. No. 108 (“Interim Order”) at 2). Defendants did not appear. Then, lacking 10 defendants’ consent to decide the case, the magistrate judge recommended to the district judge 11 that default judgment be entered (Dkt. No. 102; see Dkt. No. 101 (“1st KHN Br.”)). Because 12 the recommended injunction burdened a third party, Amazon.com, Inc. (Dkt. No. 101-2), the 13 district judge asked Amazon to show cause why the injunction should not be entered (Dkt. 14 No. 105). (Note that Amazon.com, Inc. is a non-party filer in this action (Dkt. Nos. 98, 106, 15 110), as is Amazon.com Services, LLC (Dkt. No. 84), represented herein by Attorney Arthur 16 Kats of Davis Wright Tremaine LLP; this order refers to both corporate entities as Amazon, 17 and to the retail platform through which defendants’ products have been sold as 18 www.amazon.com.) 19 In response, Amazon pointed to problems with the proposed injunction. Ultimately, 20 plaintiff joined Amazon in requesting changes to the proposed injunction, agreeing that it now 21 saw the unresolved problems and furthermore agreeing on how best to solve them by 22 modifying the proposed injunction (Dkt. No. 106 § II (“Prior Proposed Inj.”)). 23 This prompted the district judge to take a fresh look at the contemplated relief, turning up 24 more problems. Nonetheless, plaintiff needed relief (Interim Order 8–9). Plaintiff had asserted 25 allegations and produced some evidence that some defendants were selling an important safety 26 product — a breathalyzer — that simply did not work. Defendants were profiting from 27 American markets by diverting at least some sales from plaintiff (and endangering consumers) 1 Thus, to smoke out defendants, an order granted interim relief to disable the sellers’ 2 accounts on Amazon’s platform and to impound revenues accrued from selling the specific 3 breathalyzer that the supporting evidence showed was clearly defective. The relief was 4 “designed to prompt defendants to appear to defend their conduct so that we c[ould] reach a 5 decision on the merits. [If] defendants fail[ed] to appear as ordered, this Court w[as to] invite 6 plaintiff to enter a renewed motion for default judgment” (id. at 10). 7 2. THE EFFECT OF INTERIM RELIEF. 8 Plaintiff served defendants using the approved alternatives (see Dkt. No. 112 (“2d KHN 9 Br.”) at 1). Amazon disabled the sellers’ accounts and sent additional, voluntary notices to the 10 sellers using its own methods (Dkt. No. 110). 11 Plaintiff soon received an email asking that the injunction be dissolved as to one enjoined 12 seller account (2d KHN Br. 1 n.1) — an email that evolved into a motion on our docket. The 13 email and motion came from a Florida-based lawyer representing two third parties who 14 claimed to sell only wigs, not breathalyzers, and who said they had been voluntarily dismissed 15 from this suit in 2023. These third parties were the company Jinhua Kalu Wigs. Co., Ltd. and 16 the person Zhou Chan, apparently the company’s owner and operator (collectively 17 “Wigs. Co.”) (see ibid.; Dkt. No. 77 (prior dismissal); Dkt. No. 118 (“Wigs. Co. Br.”)). 18 Because plaintiff admitted to the Court that it could not disprove this chain of purported facts 19 with certainty, plaintiff agreed to drop the Wigs. Co. seller account from the injunction 20 (Amazon Seller ID A3RBBHIOC0BOQY) (see 2d KHN Br. 1 n.1). 21 At a hearing on this interim request, the Court interrogated counsel for plaintiff and then 22 counsel for Wigs. Co. (see Dkt. No. 124). It seemed to the Court that plaintiff’s lawyers might 23 be seeking a quick payday by letting parties that showed up leave the suit while seeking 24 impoundment only as to those who failed to put up a fight. It also seemed to the Court that 25 plaintiff’s lawyers might not have sufficient documentation to merit default judgment if they 26 could not reliably trace specific offending sales to specific seller accounts to specific 27 defendants in our case. 1 Plaintiff’s counsel said none of this was so. To avoid even the appearance of seeking a 2 payday, plaintiff’s counsel agreed to drop any damages from the proposed final relief. Indeed, 3 plaintiff’s counsel represented that the interim injunction in fact had failed to impound funds in 4 the sellers’ accounts at all because all funds had left those accounts sometime after this 5 litigation began but before the interim injunction (see Dkt. No. 124). What mattered most to 6 the plaintiff client was enjoining sales of the cheap but defective breathalyzer. And, to that 7 point, counsel produced in camera the records it had used to perform its tracing. It now 8 seemed Wigs. Co. had been wrongly ensnared as a defendant from the start despite having 9 made no sales of the offending product, and that after Wigs. Co. was voluntarily dismissed a 10 mistake by plaintiff’s counsel resulted in the Wigs. Co. seller account number remaining 11 lumped in with the seller account numbers of the others still in suit. 12 The Court pressed counsel to document end to end the exact links between problematic 13 sales and the defendants and to pare down the proposed injunction accordingly in order to 14 prevent mistake and to provide only the most robustly supported relief (e.g., Dkt. No. 123). 15 3. THE PARED-DOWN, PROPOSED PERMANENT INJUNCTION. 16 Plaintiff submitted a freshly proposed injunction and default judgment (Dkt. No. 125 17 (“Proposed Inj.”)). Its scope was pared down. And, its support was shored up by 18 supplementary briefing and evidentiary submissions that tried to link the offending sales to the 19 seller accounts to the defendants in our case (Dkt. No. 129). 20 This proposal remains the one at issue in this motion. It nearly resolves the problems 21 earlier identified, through these critical changes: 22 1. Now only one identified product — not three — is to be enjoined from being sold, this product being the only 23 breathalyzer for which specific record evidence shows false advertising and defective performance (compare Prior 24 Proposed Inj. ¶ a.ii, with Proposed Inj. ¶ 3); 25 2.
