8 Plaintiff, ORDER QUASHING SERVICE TO LBF 9 v. TRAVEL; ORDER TO SHOW CAUSE WHY DEFENDANT SKYSCANNER 10 SKYSCANNER, INC, et al., SHOULD NOT BE DISMISSED FOR IMPROPER SERVICE; ORDER 11 Defendants. DISPOSING OF REMAINING MOTIONS; ORDER CONTINUING 12 CASE MANAGEMENT CONFERENCE 13 Re: ECF Nos. 22, 24, 37, 39, 41, 48, 49, 57

14 I. BACKGROUND 15 In this action, Pro Se Plaintiff Sergey Firsov seeks damages for alleged deceptive practices 16 concerning the sale of airline tickets, naming LBF Travel, Inc., Compania Panamena de Aviacion, 17 S.A., and Skyscanner, Inc., as defendants. ECF No. 1; ECF No. 5. Defendant Compania 18 Panamena de Aviacion has been voluntarily dismissed from the action. ECF No. 38. After Firsov 19 paid the filing fee and the Court issued the summons, Firsov filed a proof of service, although the 20 sufficiency of that service is discussed further below. ECF Nos. 31, 32, 34. 21 Firsov filed a motion for default judgment on September 24, 2025, ECF No. 39, and refiled 22 it on October 6, 2025, ECF No. 48. Firsov asserts that default judgment is warranted against 23 Defendants LBF Travel and Skyscanner because they failed to respond to the complaint within 21 24 days. ECF No. 48 at 1, 2. 25 On October 8, 2025, LBF Travel filed a motion to dismiss the complaint for improper 26 service. ECF No. 41. On the same day, LBF Travel also filed an opposition to Firsov’s 27 application for default judgment, arguing that it was not required to respond to the complaint 1 effected proper service by serving the complaint upon an LBF Travel employee who identified 2 herself as authorized to receive service. ECF No. 43 at 2-3. 3 Firsov did not file an opposition to LBF Travel’s motion to dismiss the complaint for 4 improper service. However, he filed a separate motion to strike the motion to dismiss (also on 5 October 8), arguing that LBF Travel labeled it incorrectly. 1 ECF No. 44. Firsov’s motion to 6 strike also reiterated his position that the individual whom he served agreed to accept service and 7 claimed that he had also mailed the summons and complaint to LBF Travel. ECF No. 44 at 3. 8 LBF Travel opposed the motion to strike on October 22. ECF No. 53. On October 29, LBF 9 Travel also filed a “reply” in support of its motion to dismiss, noting that Firsov had failed to file 10 an opposition to it. ECF No. 55 at 1–2. 11 Firsov has also filed motions for sanctions (1) against all defendants to recover the cost of 12 formal service, ECF No. 37; and (2) against LBF Travel’s attorneys for filing the motion to 13 dismiss. ECF No. 54 at 2; ECF No. 57 at 2. LBF Travel opposed the latter motion. ECF No. 58. 14 In this order, the Court first denies Firsov’s motion to strike the motion to dismiss. 15 Turning to the motion to dismiss, the Court then finds that LBF Travel was not properly served 16 and grants Firsov 30 days to effect proper service. Next, the Court considers Firsov’s motion for 17 default judgment. Because Firsov did not file a request for entry of default by the Clerk, the 18 motion is premature. Even if he had requested the Clerk enter default, however, the Court would 19 deny the request as to LBF Travel because LBF Travel was never properly served. As to 20 Skyscanner, the Court notes inconsistencies in the proof of service filed and orders Firsov to show 21 cause why Skyscanner was properly served. Finally, the Court disposes of the remaining motions. 22 II. JURISDICTION 23 The Court has jurisdiction under 28 U.S.C. § 1331. 24 III. MOTION TO STRIKE 25 Firsov’s motion to strike the motion to dismiss, ECF Nos. 44, 49, is denied. Under Federal 26 Rule of Civil Procedure 12(f), the Court “may strike from a pleading an insufficient defense or any 27 1 redundant, immaterial, impertinent, or scandalous matter.” “[T]he function of a 12(f) motion to 2 strike is to avoid the expenditure of time and money that must arise from litigating spurious issues 3 by dispensing with those issues prior to trial . . . .” Sidney-Vinstein v. A.H. Robins Co., 697 F.2d 4 880, 885 (9th Cir. 1983). 5 The basis for Firsov’s motion to strike is that LBF Travel “filed wrong Motion to dismiss 6 with context of Motion to quash service of summons instead valid Motion to set default aside.” 7 ECF No. 44 at 1. Specifically, he complains that the motion to dismiss occasionally used the 8 phrase “quash service,” which is terminology used in California state court. ECF No. 44 at 2; see 9 ECF No. 41 at 5. The motion, however, repeatedly refers to itself properly as a motion to dismiss 10 for improper service under Federal Rule of Civil Procedure 12(b)(5). ECF No. 41 at 1–5. Firsov 11 also suggests that LBF Travel was required to file a motion to set aside a default under Federal 12 Rule of Civil Procedure 55, but the Court has not entered default in this case. ECF No. 44 at 2; 13 ECF No. 53 at 2; see Fed. R. Civ. P. 55(c). 14 Firsov has identified no “redundant, immaterial, impertinent, or scandalous” material and 15 provides no other basis upon which the Court could strike the LBF Travel’s motion to dismiss. 16 The motion is denied. 17 IV. MOTION TO DISMISS 18 Having determined that Firsov’s motion to strike the motion to dismiss is meritless, the 19 Court turns to LBF Travel’s motion to dismiss for insufficient service. ECF No. 41. 20 Rule 12(b)(5) authorizes dismissal due to insufficient service of process. In fact, the 21 procedural requirement of service of summons is a prerequisite to the Court’s exercise of personal 22 jurisdiction over a defendant. See Strong v. Countrywide Home Loans, Inc., 700 Fed. App’x 664, 23 667 (9th Cir. 2017) (citing Omni Capital Int’l, Ltd. v. Rudolf Wolff & Co., 484 U.S. 97, 104 24 (1987)); Direct Mail Specialists, Inc. v. Eclat Computerized Technologies, Inc., 840 F.2d 685, 688 25 (9th Cir. 1988). 26 On a Rule 12(b)(5) motion, the plaintiff bears the burden of establishing the validity of 27 service. See Brockmeyer v. May, 383 F.3d 798, 801 (9th Cir. 2004). The process server’s “signed 1 strong and convincing evidence.” S.E.C. v. Internet Sols. for Bus. Inc., 509 F.3d 1161, 1166 (9th 2 Cir. 2007) (internal quotation marks and citations omitted). 3 Under both California and federal law, a plaintiff must personally serve a summons and a 4 copy of the complaint upon a defendant. Federal Rule of Civil Procedure 4(h)(1) provides that a 5 corporation must be served either “in the manner prescribed by Rule 4(e)(1) for serving an 6 individual,” or “by delivering a copy of the summons and of the complaint to an officer, a 7 managing or general agent, or any other agent authorized by appointment or law to receive service 8 of process.” See Fed. R. Civ. P. 4(h)(1)(A)-(B).
