Opinion

KAMRAN MAMMADOV, an individual, Case No.: 25-cv-2652-BJC-SBC Plaintiff, ORDER GRANTING IN PART AND DENYING IN PART DEFENDANT’S v. MOTION TO DISMISS PHARMACEUTICALS, a Pennsylvania [ECF No. 4] corporation; BTG INTERNATIONAL, a Pennsylvania corporation; SERB SPECIALTY PHARMACEUTICALS, a Pennsylvania corporation; and DOES 1 through 100, inclusive, Defendants. Defendant BTG International Inc. (“BTG”) moves to dismiss Plaintiff Kamran Mammadov’s Complaint for lack of personal jurisdiction, insufficient process, and insufficient service of process. ECF No. 4. Plaintiff opposes the motion. For the following reasons, the Court GRANTS IN PART AND DENIES IN PART Defendant BTG’s motion to dismiss. // // Defendant BTG is incorporated in Delaware and has its corporate headquarters in Pennsylvania. ECF No. 4-3 ¶ 3. Plaintiff Kamran Mammadov lives in San Diego, California, and was hired by BTG in 2023. ECF No. 6-1 ¶¶ 6, 10. The parties discussed plans for Plaintiff to move to the East Coast to work, but he started working out of his “field-based home office” in San Diego, where he resided prior to, during, and after his employment with BTG. ECF No. 4-3 ¶ 10; ECF No. 6-1 ¶ 19. Although the parties disagree on how certain these plans were when Plaintiff was hired, Defendant knew Plaintiff would be working remotely from California for some indefinite period. ECF No. 6-1 ¶ 19. Plaintiff alleges that Defendant violated numerous California laws by forcing him to work during medical leave, retaliating and discriminating against him for his health conditions and religious background, and terminating him on October 21, 2024, for internal whistleblower activities. ECF No. 1-2 ¶¶ 127, 135-40, 141-76, 256. Plaintiff originally filed a complaint in San Diego Superior Court on June 10, 2025, asserting claims for retaliation, wrongful termination, employment discrimination, failure to engage in the interactive process, failure to accommodate, harassment, failure to prevent discrimination, and unfair business practices. ECF No. 1-2. He filed a Proof of Service of Summons in San Diego Superior Court on September 16, 2025, claiming to have served process on Samuel Angie at 5235 North Front Street, Harrisburg, Pennsylvania 17110, on September 5, 2025. ECF No. 4-2 ¶ 2, Exhibit 1. The service was directed to “BTG INTERNATIONAL, A PENNSYLVANIA CORPORATION,” which is not a legal entity. ECF No. 1-3 ¶ 5. Plaintiff also filed a Proof of Service of Summons in San Diego Superior Court on “SERB SPECIALTY PHARMACEUTICALS, A PENNSYLVANIA CORPORATION,” which is also not a legal entity. Id. ¶ 4, 5. This proof of service explained that service was made on Jeffrey Ginn at 46 Shelby Thames Dr., Hattiesburg, Mississippi, 39402. ECF No. 4-2, Exhibit 2. // Defendant removed the action to federal court on October 6, 2025, and filed its Motion to Dismiss pursuant to Federal Rules of Civil Procedure 12(b)(2), (4), and (5) on October 14, 2025. ECF Nos. 1, 4. Plaintiff filed an Opposition to Defendant’s Motion to Dismiss on November 18, 2025, and Defendant filed a Reply to Plaintiff’s Opposition on November 24, 2025. ECF Nos. 6, 8. A. Personal Jurisdiction i. Legal Standard A motion to dismiss under Federal Rule of Civil Procedure 12(b)(2) should be granted when a court lacks personal jurisdiction over a defendant. Fed. R. Civ. P. 12(b)(2). “Where a defendant moves to dismiss a complaint for lack of personal jurisdiction, the plaintiff bears the burden of demonstrating that jurisdiction is appropriate.” Schwarzenegger v. Fred Martin Motor Co., 374 F.3d 797, 800 (9th Cir. 2004) (quoting Sher v. Johnson, 911 F.2d 1357, 1361 (9th Cir. 1990)). The plaintiff need only make a prima facie showing of jurisdictional facts when a court determines personal jurisdiction through the use of affidavits from the parties, without an evidentiary hearing. Ballard v. Savage, 65 F.3d 1495, 1498 (9th Cir. 1995). “[F]ederal courts ordinarily follow state law in determining the bounds of their jurisdiction over persons.” Daimler AG v. Bauman, 571 U.S. 117, 125 (2014). “Because California’s long-arm statute allows the exercise of personal jurisdiction to the full extent permissible under the U.S. Constitution,” personal jurisdiction is proper if it “comports with due process.” Picot v. Weston, 780 F.3d 1206, 1211 (9th Cir. 2015). Due Process requires minimum contacts “such that the maintenance of the suit does not offend ‘traditional notions of fair play and substantial justice.’” Int’l Shoe Co. v. Washington, 326 U.S. 310, 316 (1945) (quoting Milliken v. Meyer, 311 U.S. 457, 463 (1940)). Personal jurisdiction over a non-resident defendant may be either general or specific. Boschetto v. Hansing, 539 F.3d 1011 (9th Cir. 2008). General jurisdiction requires that the defendant maintain “affiliations with the [forum state that] are so ‘continuous and systematic’ as to render them essentially at home in the forum state.” Goodyear Dunlop Tires Operations, S.A. v. Brown, 564 U.S. 915, 919 (2011) (quoting Int’l Shoe, 326 U.S. at 317). By contrast, specific jurisdiction requires less extensive contacts with the forum state, but it can only apply to a “cause of action arising directly out of [the defendant’s] forum contacts . . . .” CollegeSource, Inc. v. AcademyOne, Inc., 653 F.3d 1066, 1075 (9th Cir. 2011). ii. Analysis Defendant argues the Court lacks general and specific personal jurisdiction over Defendant BTG. Plaintiff does not challenge the lack of general personal jurisdiction but argues that specific personal jurisdiction over Defendant BTG is proper. The Ninth Circuit employs a three-prong test for specific personal jurisdiction: (1) The non-resident defendant must purposefully direct his activities or consummate some transaction with the forum or resident thereof; or perform some act by which he purposefully avails himself of the privilege of conducting activities in the forum, thereby invoking the benefits and protections of its laws;

(2) the claim must be one which arises out of or relates to the defendant’s forum- related activities; and

(3) the exercise of jurisdiction must comport with fair play and substantial justice, i.e. it must be reasonable.
